Cautionary Note regarding Forward-Looking Statements
In addition to historical information, this Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Forward-looking statements are those that predict or describe future events or trends and that do not relate solely to historical matters. You can generally identify forward-looking statements as statements containing the words “believe,” “expect,” “will,” “anticipate,” “intend,” “estimate,” “project,” “assume” or other similar expressions, although not all forward-looking statements contain these identifying words. Some of the things that could cause our actual results to differ from our expectations are: changes in our operating costs including fuel, which can be volatile; the competitive environment and other trends in our industry; our ability to meet our cost reduction goals; labor disputes; economic conditions; our reliance on automated systems; increases in government fees and taxes; actual or threatened terrorist attacks, global instability and potential U.S. military actions or activities; insurance costs; changes in laws and regulations; liability and other claims asserted against us; operational disruptions; compliance with financial covenants; our ability to attract and retain qualified personnel; third-party vendors and partners; continuing operating losses; our significant indebtedness; and downgrades of our credit ratings and availability of financing. For a discussion of these and other risk factors, see Item 7 of the Company’s Annual Report for the year ended December 31, 2004 on Form 10-K under the caption “Risk Factors.” All of the forward-looking statements are qualified in their entirety by reference to the risk factors discussed therein. These risk factors may not be exhaustive. We operate in a continually changing business environment, and new risk factors emerge from time to time. Management cannot predict such new risk factors, nor can it assess the impact, if any, of such new risk factors on our business or events described in any forward-looking statements. We disclaim any obligation to publicly update or revise any forward-looking statements after the date of this report to conform them to actual results. Over time, our actual results, performance or achievements will likely differ from the anticipated results, performance or achievements that are expressed or implied by our forward-looking statements, and such differences might be significant and materially adverse.

Alaska Air Group, Inc.
Note 1. Basis of Presentation and Significant Accounting Policies
Organization and Basis of Presentation
The accompanying unaudited condensed consolidated financial statements of Alaska Air Group, Inc. (Air Group or the Company) include the accounts of the parent company, Alaska Air Group, Inc., and its principal subsidiaries, Alaska Airlines, Inc. (Alaska) and Horizon Air Industries, Inc. (Horizon), through which the Company conducts substantially all of its operations. These interim condensed consolidated financial statements are unaudited and should be read in conjunction with the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2004. In the opinion of management, all adjustments have been made which are necessary to present fairly the Company’s financial position as of June 30, 2005, as well as the results of operations for the three and six months ended June 30, 2004 and 2005. The adjustments made were of a normal recurring nature.
The Company’s condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). In preparing these condensed consolidated financial statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities, as well as the reported amounts of revenues and expenses. Significant estimates made include assumptions used to record liabilities, expenses and revenues associated with the Company’s Mileage Plan, amounts paid to lessors upon aircraft lease terminations, the fair market value of surplus or impaired aircraft, engines and parts, assumptions used in the calculations of pension expense in the Company’s defined benefit plans, and the amounts of certain accrued liabilities. Actual results may differ from the Company’s estimates.
Reclassifications
Certain reclassifications have been made to conform the prior year’s data to the current format.
Stock Options
The Company applies the intrinsic value method in accordance with the provisions of Accounting Principles Board (APB) Opinion No. 25, “Accounting for Stock Issued to Employees”, and related Interpretations in accounting for stock options.

During the fourth quarter of 2004, the Financial Accounting Standards Board issued SFAS 123R, “Share Based Payment: An Amendment of SFAS Nos. 123 and 95”. The new standard requires companies to recognize as expense the fair value of stock options and other equity-based compensation issued to employees as of the grant date. This new standard will apply to both stock options that we grant to employees and our Employee Stock Purchase Plan, which features a look-back provision and allows employees to purchase stock at a 15% discount. Implementation of SFAS 123R will be effective January 1, 2006. Our options are typically granted with ratable vesting provisions, and we intend to amortize compensation cost over the service period using the straight line method. We intend to use the “modified prospective method” upon adoption whereby previously awarded but unvested equity awards are accounted for in accordance with SFAS 123R and prospective amounts are recognized in the income statement instead of simply being disclosed. Once adopted, we expect our stock based compensation expense, as measured under SFAS 123R, will be approximately $6 million to $10 million per year on a pre-tax basis.
Note 2. Change in Accounting Principle
Effective January 1, 2005, the Company changed its method of accounting for major airframe and engine overhauls from the capitalize and amortize method to the direct expense method. Under the former method, these costs were capitalized and amortized to maintenance expense over the shorter of the life of the overhaul or the remaining lease term. Under the direct expense method, overhaul costs are expensed as incurred. The Company believes that the direct expense method is preferable because it eliminates the judgment and estimation needed to determine overhaul versus repair allocations in maintenance activities. Additionally, the Company’s approved maintenance program for the majority of its airframes now focuses more on shorter, but more frequent, maintenance visits. Management also believes that the direct expense method is the predominant method used in the airline industry. Accordingly, effective January 1, 2005, the Company wrote off the net book value of its previously capitalized airframe and engine overhauls for all aircraft in a charge totaling $144.7 million pre-tax ($90.4 million after tax). The Company does not believe disclosing the effect of adopting the direct expense method on net income for the period ended June 30, 2005 provides meaningful information because of changes in the Company’s maintenance program, including the execution of a “power by the hour” engine maintenance agreement with a third party in late 2004.
Note 3. Restructuring Charges
During the second quarter of 2005, Alaska announced that it was contracting out ramp services at the Seattle-Tacoma International Airport. This event resulted in a reduction of approximately 475 employees in Seattle. Severance and related costs associated with this restructuring are estimated at $16.1 million, which was recorded in the second quarter.
During the third quarter of 2004, Alaska announced a management reorganization and the closure of its Oakland heavy maintenance base, contracting out of the Company’s fleet service and ground support equipment and facility maintenance functions, as well as other initiatives.

Restructuring charges totaling $53.4 million were recorded in 2004, with $38.7 million remaining accrued at December 31, 2004.
The following table displays the activity and balance of the severance and related costs components of the Company’s restructuring accrual as of and for the six months ended June 30, 2005. The restructuring charge adjustment relates to our change in estimated costs of medical coverage extended to impacted employees and a change in the number of employees affected. We expect to record similar adjustments in future quarters as actual medical costs become known. There were no restructuring charges during the first six months of 2004 ($ in millions):

The Company will make the majority of the remaining cash payments during the third and fourth quarters of 2005. The balance at June 30, 2005 is included in accrued wages, vacation and payroll taxes in the consolidated balance sheets.
During March 2005, the Company notified the Port of Oakland of its decision to terminate the lease for the Oakland hangar as part of its ongoing restructuring efforts. Accordingly, the Company recorded an impairment charge of $7.7 million in the first quarter of 2005 for the leasehold improvements that will be abandoned as a result of the lease termination. Additionally, the Company recorded a charge of $0.3 million for certain costs associated with the lease termination, all of which has been paid as of June 30, 2005.
Note 4. Derivative Financial Instruments
The Company records all derivative instruments, all of which are currently fuel hedge contracts, on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in earnings.
The Company’s operations are inherently dependent upon the price and availability of aircraft fuel, which accounted for 20.0% of all of 2004 and 22.2% of year-to-date 2005 operating expenses (excluding impairment and restructuring charges). To manage economic risks associated with fluctuations in aircraft fuel prices, the Company enters into swap agreements and call options for crude oil.

Because of variations in the spread between the prices of West Texas Intermediate crude oil and jet fuel since the second quarter of 2004, the Company’s hedge contracts are not “highly correlated” to changes in prices of aircraft fuel, as defined in SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities.” The impacts on the Company’s reported results are as follows:
    All changes in the fair value of fuel hedge contracts that existed as of March 31, 2004 or hedge positions entered into subsequent to March 31, 2004 are reported in other non-operating income (expense).
 
    Reported fuel expense includes only the effective portion of gains associated with hedge positions that settled during the current period on contracts that existed at March 31, 2004 to the extent that mark-to-market gains were already included in Accumulated Other Comprehensive Loss at March 31, 2004.

Note 8. Earnings Per Share
SFAS No. 128, “Earnings per Share” requires that companies use income from continuing operations before extraordinary items and the cumulative effect of an accounting change as the “control number” in determining whether potential common shares are dilutive or antidilutive. As the Company reported income before the accounting change for both the quarter and the six months ended June 30, 2005, the potential common shares from the Company’s common stock options and senior convertible notes are included in the calculation for diluted earnings (loss) per share. Therefore, for the three and six months ended June 30, 2005, the dilutive impact of common stock options and 5.8 million common shares that would have been outstanding upon conversion of the senior convertible notes were included in the calculations. Outstanding options to purchase 1.9 million common shares were excluded from the calculation in 2005 as the impact of those options would have been antidilutive. For the three and six months ended June 30, 2004, options to purchase 3.9 million shares and the effect of the senior convertible notes were excluded from the computation of diluted loss per share in 2004 because the impact would have been antidilutive. Income (loss) per share was calculated as follows (in millions except per share amounts).

During the first six months of 2005, Horizon issued $20.0 million of debt secured by flight equipment, having a fixed interest rate of 6.07% and a fifteen-year term.
During 2004, Alaska repaid its $150 million credit facility and, on December 23, 2004, that facility expired. On March 25, 2005, Alaska Airlines, Inc. finalized a $160 million variable rate credit facility with a syndicate of financial institutions that will expire in March 2008. The interest rate on the credit facility varies depending on certain financial ratios specified in the agreement with a minimum interest rate of LIBOR plus 200 basis points. Any borrowings will be secured by either aircraft or cash collateral. This credit facility contains contractual restrictions and requires maintenance of specific levels of net worth, maintenance of certain debt and leases to net worth, leverage and fixed charge coverage ratios, and limits on liens, asset dispositions, dividends, and certain other expenditures. Such provisions restrict Alaska Airlines from distributing any funds to Alaska Air Group in the form of dividends and limit the amount of funds Alaska Airlines can loan to Alaska Air Group. As of June 30, 2005, $300.0 million was available to loan to Alaska Air Group without violating the covenants in the credit facility. As of June 30, 2005, there are no outstanding borrowings on this credit facility.
In the second quarter of 2005, the Company exercised its option under several of its existing variable rate long-term debt arrangements to fix the interest rates through maturity. The fixed rates on these affected debt arrangements range from 5.2% to 6.3%. These changes did not result in any gain or loss in the consolidated statements of operations.
Note 11. Aircraft Commitments
Alaska entered into an aircraft purchase agreement during the second quarter of 2005 to acquire 35 B737-800 aircraft with deliveries beginning in January 2006 and continuing through April 2011. The purchase agreement also includes options to purchase an additional 15 aircraft. Concurrent with the execution of this purchase agreement, Alaska paid $110.9 million in aircraft purchase and option deposits using cash and a credit of $9.7 million received from the manufacturer. The $9.7 million credit has been deferred as other liabilities in the Company’s balance sheet and will be applied to the purchase price of future aircraft upon delivery.
As of June 30, 2005, the Company has firm purchase commitments for 44 aircraft requiring aggregate future payments of approximately $1.4 billion. In addition to the 15 options noted above, Horizon has options to purchase 11 Q400’s and 19 CRJ 700’s. Alaska and Horizon expect to finance the firm orders and, to the extent exercised, the option aircraft with leases, long-term debt or internally generated cash.
Note 12. Contingencies
The Company is a party to routine litigation incidental to its business and with respect to which no material liability is expected. Management believes the ultimate disposition of these matters is not likely to materially affect the Company’s financial position or results of operations. However, this belief is based on management’s current understanding of the relevant law and facts; it is

subject to various contingencies, including the potential costs and risks associated with litigation and the actions of judges and juries.
In May 2005, the Air Line Pilots Association filed a lawsuit in federal district court in Seattle to overturn the current labor contract covering Alaska’s pilots as established by an arbitrator, which was effective May 1, 2005. In the unlikely event that the arbitrator’s decision is overturned, Alaska may be required to pay wages retroactively to May 1, 2005 as if the contract that existed prior to the arbitrator’s decision were still in effect. On July 21, 2005, the Company filed a motion to dismiss the lawsuit. The motion will be decided on evidence submitted or following oral argument. A decision is expected in the third quarter of 2005. At this time, the Company has no reason to believe that an unfavorable outcome is likely.
In March 2005, the Company filed a claim against the International Association of Machinists (IAM) seeking to compel arbitration of the dispute regarding the subcontracting of the Company’s ramp service operation in Seattle. In May 2005, the IAM filed a counter claim against the Company alleging that the Company violated the status quo and engaged in bad faith bargaining. On May 13, 2005, the Company announced that it had subcontracted the ramp service operation in Seattle, resulting in the immediate reduction of approximately 475 employees represented by the IAM. Shortly after this event, the IAM filed a motion for a preliminary injunction seeking to reverse the subcontracting by the Company. That motion was heard and denied by a federal court judge on June 2, 2005. The Company’s lawsuit and the IAM’s counterclaim are still pending in federal court. A discovery schedule and trial date have not yet been set. At this time, the Company has no reason to believe that an unfavorable outcome is likely.

Note A:
Pursuant to Item 10 of Regulation S-K, we are providing disclosure of the reconciliation of reported non-GAAP financial measures to their most directly comparable financial measures reported on a GAAP basis. The non-GAAP financial measures provide management the ability to measure and monitor performance both with and without the cost of aircraft fuel (including the gains and losses associated with our fuel hedging program where appropriate), restructuring charges, and aircraft impairment charges. Because the cost and availability of aircraft fuel are subject to many economic and political factors beyond our control and we record changes in the fair value of our hedge portfolio in our income statement, it is our view that the measurement and monitoring of performance without fuel is important. In addition, we believe the disclosure of financial performance without impairment and restructuring charges is useful to investors. Finally, these non-GAAP financial measures are also more comparable to financial measures reported to the Department of Transportation by other major network airlines.
The following tables reconcile our non-GAAP financial measures to the most directly comparable GAAP financial measures for both Alaska Airlines, Inc. and Horizon Air Industries, Inc.:

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion should be read in conjunction with our condensed consolidated financial statements and the related notes contained elsewhere in this quarterly report on Form 10-Q. All statements in the following discussion that are not reports of historical information or descriptions of current accounting policy are forward-looking statements. Please consider our forward-looking statements in light of the risks referred to in this report’s introductory cautionary note.
Air Group’s filings with the Securities and Exchange Commission, including its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports are accessible free of charge at www.alaskaair.com . The information contained on our website is not a part of this quarterly report on Form 10-Q. As used in this Form 10-Q, the terms “Air Group,” “our,” “we” and the “Company” refer to Alaska Air Group, Inc. and its subsidiaries, unless the context indicates otherwise.
Second Quarter in Review and Current Events
In the second quarter of 2005, despite nearly flat capacity, revenues continued to improve due to increases in passenger traffic at both Alaska and Horizon, coupled with a modest improvement in ticket yields at Alaska over prior year. Operating expenses per available seat mile increased 4.2% at Alaska to 11.09 cents and 0.5% at Horizon to 15.57 cents compared to the second quarter of 2004. Fuel is a major component of our operating costs and fuel prices reached record highs once again in the second quarter. At Alaska, our unit costs excluding fuel, impairment, and restructuring charges during the second quarter of 2005 increased slightly compared to the second quarter of 2004. This is due to the reduction in capacity at Alaska from the prior year quarter due to the reduction of our 2005 summer flight schedule. Horizon, however, continued to see improvement in unit costs excluding fuel, impairment, and restructuring charges over the prior period. Our cost per available seat mile excluding fuel, impairment, and restructuring charges increased 1.4% at Alaska to 8.09 cents and declined 4.9% at Horizon to 12.78 cents compared to the second quarter of 2004.
Although revenues and pretax income at Alaska have improved over the prior year, we are facing several operational difficulties due to the combined effects of the recent labor and operational changes across our company. The result has been operational performance that is well below our goal. Our operational performance, measured by on-time arrivals and departures, declined significantly from the second quarter of 2004. In order to improve our operational performance, we reduced our capacity throughout the remainder of 2005 from our original expectations through schedule reductions and the elimination of certain flights. This capacity reduction will impact our revenue in the third and fourth quarters, although the impact is not known at this time.
Labor Costs and Negotiations
Despite ongoing negotiations in late 2003 and much of 2004, we were unable to reach a new agreement with the Air Line Pilots Association (ALPA) and, therefore, pursuant to the terms of the collective bargaining agreement, submitted to binding arbitration during the first quarter of 2005, the

25


Table of Contents

decision of which became effective on May 1, 2005. The arbitration resulted in an average pilot wage reduction of approximately 26%, various work rule changes that should result in productivity improvements, and higher employee health care contributions. No changes were made to the pilots’ pension plan. Subsequent to the arbitrator’s decision, the Company and ALPA reached a tentative agreement that, among other things, provided an across-the-board 20% reduction of pilot’s wages rather than the average 26% reduction from the arbitrator’s decision and a number of work rule changes. The pilot group rejected this agreement on July 11, 2005 and, therefore, the contract resulting from the arbitrator’s decision will stand and will become amendable on May 1, 2007. We have reached a tentative agreement with ALPA to resolve certain aspects of the current contract such as vacation and training pay, health care and profit sharing. ALPA filed a lawsuit in federal district court to vacate the arbitrator’s decision. At this time, the Company has no reason to believe that an unfavorable outcome is likely (See Part II: Other Information – Item 1: Legal Proceedings).
During the second quarter of 2005, we presented a contract offer to the International Association of Machinists (IAM, representing our ramp workers) that was rejected by this work group. We subcontracted our Seattle ramp operations to a third party effective May 13, 2005. This resulted in an immediate reduction of approximately 475 employees. We offered a severance package, substantially the same as the severance packages offered to other employees in late 2004, to those affected by the subcontracting that included cash payments based on years of service, one year of medical coverage after the severance date and continued travel benefits for a period of time. The IAM accepted the severance package in June 2005 and, as a result, we recorded a charge of $16.1 million in the second quarter of 2005 related to the restructuring, which was offset by a $1.4 million adjustment related to the remaining restructuring liability from our prior restructuring efforts, resulting in a net restructuring charge of $14.7 million. The IAM has filed a lawsuit in federal court alleging a violation of the status quo and that we engaged in bad faith bargaining. At this time, the Company has no reason to believe that an unfavorable outcome is likely (See Part II: Other Information – Item 1: Legal Proceedings).
A tentative agreement with the Association of Flight Attendants (AFA) was rejected by the majority of Alaska’s flight attendants on July 19, 2005. A tentative agreement with the Aircraft Mechanics Fraternal Association (AMFA) was rejected by the majority of Alaska’s aircraft technicians on July 27, 2005. The Company will resume talks with the AFA and AMFA soon to determine next steps in these processes.
Although we are disappointed that we have not been able to secure contracts with IAM, AFA, or AMFA thus far, we believe the negotiations to date have been productive. None of the contract negotiations is at an impasse or has reached the 30 day cooling off period required under the Railway Labor Act that would trigger self help. Therefore, we currently believe the risk of a work stoppage or other material service disruption in the near future is very low.

Mark-to-Market Fuel Hedging Gains
Beginning in the second quarter of 2004, we lost the ability to defer, as a component of comprehensive income, recognition of any unrealized gain or loss on our fuel hedge contracts until the hedged fuel is consumed. We lost this ability because the price correlation between crude oil, the commodity we use to hedge, and West Coast jet fuel fell below required thresholds. For more discussion, see Note 4 to our condensed consolidated financial statements.
The implications of this change are twofold: First, our earnings can be more volatile as we mark our entire hedge portfolio to market each quarter-end and report the gain or loss in other non-operating income or expense, even though the actual consumption will take place in a future period. In times of rising fuel prices such as the second quarter of 2005, this will have the effect of increasing our reported net income or decreasing our reported net loss. Our mark-to-market gains recorded in the second quarter of 2005 for contracts that settle in future periods were $3.0 million compared to $22.3 million in the second quarter of 2004. Second, to a large extent, the impact of our fuel hedge program will not be reflected in fuel expense. In the second quarter of 2005, we recorded gains from settled fuel hedges totaling $28.2 million, but only $3.7 million of that gain is reflected as an offset to fuel expense with the balance reported in other non-operating income. In the second quarter of 2004, gains of $5.0 million on settled hedges were recorded as an offset to fuel expense and gains of $3.6 million were recorded in non-operating income related to settled hedges.
We have provided information on mark-to-market gains or losses, as well as calculations of our economic fuel cost per gallon on pages 23 and 24.
We continue to believe that our fuel hedge program is an important part of our strategy to reduce our exposure to volatile fuel prices.
Impairment of 737-200C Aircraft in 2004
In the second quarter of 2004, our Board approved a plan to accelerate the retirement of our Boeing 737-200C fleet and remove those aircraft from service earlier than initially planned. As a result of this decision, we recorded an impairment charge totaling $36.8 million (pretax) to write down the fleet to its estimated fair market value.
Aircraft Commitment
On June 15, 2005, Alaska Airlines, Inc. entered into an aircraft purchase agreement with The Boeing Company to purchase 35 B737-800 aircraft with deliveries beginning in January 2006 and continuing through April 2011. The purchase agreement includes options to purchase an additional 15 aircraft with deliveries between July 2007 and April 2009. The order also includes rights to purchase an additional 50 737-800s under the same terms as the agreement.
Capacity Outlook
For 2005, Alaska and Horizon expect capacity to be flat and up approximately 10%, respectively, compared to 2004 capacity. We recently reduced the estimated capacity forecast for the remainder of

27


Table of Contents

the year for Alaska due to schedule reductions that are being made to improve operational reliability. Horizon’s expected capacity increase is due largely to the annualization of aircraft additions in the last half of 2004, the addition of one new CRJ-700 in the first quarter of 2005, and higher utilization resulting from the annualization of the contract flying for Frontier. In addition, Horizon has completed the addition of a row of seats to the Q400 fleet increasing capacity from 70 to 74 seats.
We expect to begin service to Dallas/Fort Worth in September 2005. During the second quarter, we announced service from Los Angeles to Mexico City beginning in August 2005.
Results of Operations
Comparison of Three Months Ended June 30, 2005 to Three Months Ended June 30, 2004
Our consolidated net income for the second quarter of 2005 was $17.4 million, or $0.56 per diluted share, versus a net loss of $1.7 million, or $0.06 per diluted share, in the second quarter of 2004.
Our consolidated operating income for the second quarter of 2005 was $9.1 million compared to an operating loss of $20.6 million during the same period of 2004. Our consolidated pre-tax net income for the quarter was $29.7 million compared to a pre-tax loss of $0.7 million for the second quarter of 2004. Both the 2005 and 2004 results include certain significant items that impact the comparability of the quarters. These items are discussed in the “Second Quarter in Review and Current Events” section beginning on page 25. Excluding those items, the quarter over quarter improvement can be characterized by higher revenues, offset by significantly higher fuel costs and relatively flat operating expenses. Wages and benefits declined significantly due to some of the recent initiatives and new pilot contract at Alaska. However, these declines were largely offset by higher operating expenses in other areas.
Financial and statistical data comparisons for Alaska and Horizon are shown on pages 21 and 22, respectively. On pages 23 and 24, we have included a reconciliation of reported non-GAAP financial measures to the most directly comparable GAAP financial measures.
Alaska Airlines Revenues
Operating revenues increased $38.7 million, or 6.7%, during the second quarter of 2005 as compared to the same period in 2004. For the quarter, revenue passenger miles (RPMs or traffic) increased 5.2% over prior year and ticket yields per passenger mile increased approximately 2.5%. The increase in yield per passenger mile was a result of a modest increase in ticket prices industry-wide designed to offset higher fuel prices.
Our operating revenues per available seat mile (ASM) increased by 8.4% compared to the prior year driven primarily by the increase in ticket yields as discussed above and a 1.6% decline in ASMs. The capacity decreases are primarily due to the reduction in our flight schedule that was announced in June 2005 and the retirement of two B737-200s in 2004, offset by the additional seats added to the B737-400 fleet during the fourth quarter of 2004 and the addition of two B737-800s in the first quarter of 2005. The increase in traffic offset by the capacity decrease, resulted in an increase in load factor

28


Table of Contents

from 72.8% to 77.9%. We expect that load factors will continue to be strong and that yields and passenger unit revenues will continue to trend slightly higher through the remainder of 2005.
Freight and mail revenues increased $0.8 million, or 3.5%, compared to the same period in 2004 because of a relatively new mail contract we have in the State of Alaska offset by lower freight revenues.
Other-net revenues decreased $3.4 million, or 9.8%, due to the termination of contract maintenance work that we were performing for third parties in the second quarter of 2004 and are no longer performing. This was offset by increases in Mileage Plan revenues, resulting from higher award redemption on our partner airlines and an increase in cash receipts from miles sold.
Alaska Airlines Expenses
For the quarter, total operating expenses increased $15.5 million, or 2.6%, as compared to the same period in 2004 despite a 1.6% decrease in capacity. Operating expenses per ASM increased 4.2% from 10.63 cents in the second quarter of 2004 to 11.09 cents in the second quarter of 2005. The increase in operating expenses is due largely to the significant increases in fuel costs, the restructuring charge related to the subcontracting of the ramp services operation in Seattle, contracted services costs, aircraft maintenance, and landing fees and other rentals, offset by a decline in wages and benefits and food and beverage service. Operating expense per ASM excluding fuel, restructuring and impairment charges increased 1.4% as compared to the same period in 2004. Our estimates of costs per ASM, excluding fuel and restructuring or impairment charges, for the third quarter, fourth quarter and full year of 2005 are 7.4 cents, 7.4 cents, and between 7.8 and 7.9 cents, respectively.
Explanations of significant period-over-period changes in the components of operating expenses are as follows:
    Wages and benefits decreased $21.7 million, or 10.7%, during the second quarter. Wages have been favorably impacted by the restructuring initiatives announced in August and September of 2004 and the reduction in pilot wages resulting from the arbitrator’s decision in May 2005. Additionally, during the second quarter of 2005, we subcontracted our ramp services operation in Seattle. We expect a greater year-over-year decline in wages in the third quarter of 2005 as we see the full effect of some of these changes, with the increase tapering down as we get into the fourth quarter. We estimate that wages and benefits will decline approximately $34 million, or 16%, in the third quarter and $19 million, or 10% in the fourth quarter as compared to the same periods in 2004 as we complete a full year under some of the restructuring changes that were made in the fourth quarter of the prior year. The period over period declines in wages and benefits are partially offset by increases in contracted services and maintenance expense due to the subcontracting of certain operations.
 
    Contracted services increased $2.2 million, or 7.5%, due largely to the contracting out of the Company’s fleet service and ground service equipment and facility maintenance in the

29


Table of Contents

      fourth quarter of 2004, and the Seattle ramp operations in the second quarter of 2005. We expect a larger increase from prior year in the third and fourth quarters due to the ramp service operations being subcontracted for the full quarters.
 
    Aircraft fuel increased $38.9 million, or 34.5%, due to a 38.8% increase in the GAAP fuel cost per gallon, offset by a 3.1% decrease in fuel gallons consumed. The increase in aircraft fuel expense is inclusive of $3.2 million of gains from settled hedges. During the second quarter of 2005, Alaska also realized $21.3 million of gains from settled hedges, which are recorded in other non-operating income. After including all gains on settled hedges recorded during the quarter, our “economic,” or net, fuel expense increased $20.8 million, or 19.0%, over the same period in 2004. Our economic fuel cost per gallon increased 22.7% over the second quarter of 2004 from $1.23 to $1.51. At current market prices, we expect that the cost per gallon in the third and fourth quarters will meet or exceed second quarter levels.
 
      See page 23 for a table summarizing fuel cost per gallon realized by Alaska (the economic cost per gallon), the cost per gallon on a GAAP basis (including hedging gains recorded in aircraft fuel and non-operating income (expense)) and fuel cost per gallon excluding all hedging activities.
 
    Aircraft maintenance increased $9.5 million, or 23.3%, due largely to our power-by-the-hour maintenance agreement, whereby we expense B737-400 engine maintenance on a flight-hour basis, regardless of whether the work was actually performed during the period. Other factors causing the increase were the contracting out of related heavy maintenance to third parties, which resulted in a shift of costs from wages and benefits into aircraft maintenance, more airframe work and engine overhauls in 2005 compared to 2004, and the change in our accounting policy regarding engine and airframe overhauls (see Note 2 to our condensed consolidated financial statements). We expect that maintenance expense will be higher by $15 million and $6 million in the third and fourth quarters of 2005, respectively, compared to the same periods in 2004 as a result of the factors above and our decision to move the timing of some maintenance activities up from 2006.
 
    Aircraft rent increased $1.4 million, or 5.0%, due to the additional operating lease on a B737-800 that was delivered in March 2005, offset by lower rates on extended leases.
 
    Food and beverage service expense decreased $1.5 million, or 11.5%, due primarily to increased focus on cost reduction resulting in a decrease in average food and beverage cost per passenger.
 
    Landing fees and other rentals increased $5.2 million, or 14.7% despite a decrease in the number of departures. The higher rates reflect increased rental costs, primarily in Seattle, Portland and Los Angeles. We expect landing fees and other rentals to continue to increase

30


Table of Contents

      by 10% to 15% in the third and fourth quarters compared to 2004 as a result of airport facility expansions and higher costs related to airport security.
 
    Other expense increased $3.4 million, or 8.9%, primarily reflecting increases in passenger remuneration costs, professional services costs, legal settlement costs and personnel and crew costs.
Horizon Air Revenues
For the second quarter, operating revenues increased $15.9 million, or 12.8% as compared to 2004. This increase is due largely to increased traffic in the native network, partially offset by a 1.9% decline in ticket yields.
For the three months ending June 30, 2005, capacity increased 7.2% and traffic was up 15.9%, compared to the same period in 2004 due primarily to the addition of one CRJ 700, four additional seats on each of our Q400’s and an increase in the average trip length. Passenger yield decreased 1.9% to 22.08 cents per passenger mile due primarily to an increase in average trip lengths across the native network, partially as a result of increased harmonization flying with Alaska. Passenger revenues increased by $16.5 million, or 13.7%, due primarily to the increase in traffic resulting from increased harmonization flying with Alaska and in our native network.
Horizon Air Expenses
Operating expenses increased $9.5 million, or 7.7%, as compared to the same period in 2004. Operating expenses per ASM increased 0.5% as compared to 2004. Operating expenses per ASM excluding fuel and impairment charges decreased 4.9% as compared to the same period in 2004. Operating expenses in 2004 include $0.4 million related to an impairment charge on our held-for-sale F-28 aircraft and spare engines to lower the carrying value of these assets to their estimated fair value. Our estimates of costs per ASM, excluding fuel and special charges, for the third quarter, fourth quarter and full year of 2005 are 12.2 cents, 13.6 cents, and 13.2 cents, respectively.
Explanations of other significant period-over-period changes in the components of operating expenses are as follows:
    Wages and benefits increased $2.2 million, or 5.4%, reflecting a slight increase in the average wage per employee and a new performance-based incentive program for all employees, partially offset by lower workers compensation expense based on favorable claims activity.
 
    Aircraft fuel increased $7.7 million, or 48.1%, due to a 40.2% increase in the GAAP fuel cost per gallon from $1.31 in 2004 to $1.84 in 2005 and a 5.7% increase in fuel gallons consumed. The increase in aircraft fuel expense is inclusive of $0.5 million of gains from settled hedges. During the quarter, Horizon also realized $3.2 million of gains from settled hedges, which are recorded in other non-operating income (expense). After including all gains on settled hedges recorded during the quarter, our “economic,” or net, fuel expense increased $4.9

31


Table of Contents

      million, or 31.4%, over 2004. Our economic fuel cost per gallon increased 25.0% from $1.28 in 2004 to $1.59 in 2005. At current market prices, we expect that the cost per gallon in the third and fourth quarters will meet or exceed second quarter levels.
 
      See page 24 for a table summarizing fuel cost per gallon realized by Horizon (the economic cost per gallon), the cost per gallon on a GAAP basis (including hedging gains recorded in aircraft fuel and non-operating income (expense)) and fuel cost per gallon excluding all hedging activities.
 
    Aircraft maintenance expense decreased $1.3 million, or 13.8%, primarily due to the timing of our airframe and engine events and the elimination of amortization expense on capitalized airframe and engine overhauls as a result of the accounting change in the first quarter (see Note 2 to our condensed consolidated financial statements).
 
    Depreciation and amortization increased $1.0 million, or 9.0%, primarily due to the addition of one CRJ-700 at the end of the first quarter of 2005 and a Q400 delivered in the third quarter of 2004.
 
    Landing fees and other rentals increased $1.4 million, or 13.6%. Higher landing fees are a result of significant rate increases in several of our key airports. We expect landing fees and other rentals to continue to increase as a result of airport facility expansions and increased costs for security.
 
    Other expenses declined $1.1 million, or 10.3%, due primarily to reductions in aircraft liability insurance and property taxes and a gain on the sale of one of our F-28’s during the second quarter of 2005.
Consolidated Nonoperating Income (Expense )
Net nonoperating income was $20.6 million in the second quarter of 2005 compared to $19.9 million during the same period of 2004. Interest income increased $1.0 million due to a larger average marketable securities portfolio in the second quarter of 2005. Interest expense (net of capitalized interest) increased $1.7 million primarily due to interest rate increases on our variable rate debt and the changes to some of our variable rate debt agreements to slightly higher fixed rate agreements.
Fuel hedging gains include $24.5 million in gains from fuel hedging contracts settled in the second quarter of 2005 compared to $3.6 million in 2004. In addition, fuel hedging gains include net mark-to-market gains on unsettled hedge contracts of $3.0 million in 2005 and $22.3 million in 2004.
Comparison of Six Months Ended June 30, 2005 to Six Months Ended June 30, 2004
Our consolidated net loss for the six months ended June 30, 2005 was $63.1 million, or $1.82 per diluted share, versus a net loss of $44.4 million, or $1.66 per diluted share, during the same period of 2004.

Table of Contents

Our consolidated operating loss for the six months ended June 30, 2005 was $71.8 million compared to an operating loss of $79.1 million during the same period of 2004. Our consolidated income before income tax and the accounting change for the six months of 2005 was $46.7 million compared to a pre-tax loss of $66.9 million for the first six months of 2004. Both the 2005 and 2004 results include certain significant items that impact the comparability of the six-month periods. Our 2005 consolidated net income includes a $144.7 million pre-tax ($90.4 million after tax) charge resulting from the change in the method of accounting for major airframe and engine overhauls as discussed in Note 2 to the consolidated financial statements. Additionally, we recorded restructuring charges of $22.1 million ($13.8 million, net of tax) in the first six months of 2005 related primarily to the termination of the lease at our Oakland heavy maintenance base and severance and related costs resulting from the subcontracting of the ramp services operation in Seattle. The results also include mark-to-market fuel hedging gains on contracts that settle in future periods of $93.0 million during the first six months of 2005 compared to $22.8 million in the same prior year period. Financial and statistical data comparisons for Alaska and Horizon are shown on pages 21 and 22, respectively. On pages 23 and 24, we have included a reconciliation of reported non-GAAP financial measures to the most directly comparable GAAP financial measures. A discussion of the six-month data follows.
Alaska Airlines Revenues
Operating revenues increased $70.7 million, or 6.6%, during 2005 as compared to 2004.
Yield per passenger mile decreased 0.3%, although the yield trended higher in the second quarter, and passenger load factor increased 4.2 points during the first six months of 2005 as compared to the same period in 2004. The increases in traffic with relatively flat yields drove the 6.5% increase in passenger revenues in 2005.
Freight and mail revenues increased slightly by $2.4 million, or 5.9%, compared to the same period in 2004 because of a relatively new mail contract we have in the State of Alaska, offset by lower freight revenues.
Other-net revenues increased $5.0 million, or 8.5%, due largely to an increase in Mileage Plan revenues, resulting from higher award redemption on our partner airlines and an increase in cash receipts from miles sold, offset by the termination of contract maintenance work that we were performing for third parties in the second quarter of 2004 and are no longer performing.
Alaska Airlines Expenses
For the six months ended June 30, 2005, total operating expenses increased $70.1 million, or 6.2%, as compared to the same period in 2004. Operating expenses per ASM increased 5.2% in 2005 as compared to 2004. The increase in operating expenses is due largely to the significant increases in fuel costs, restructuring charges related to the subcontracting of the ramp services operation in Seattle and the closure of the Oakland hangar, contracted services costs, aircraft maintenance, and landing fees and other rentals, offset by a decline in wages and benefits, food and beverage service, other

33


Table of Contents

selling expenses and commissions and depreciation and amortization. Operating expense per ASM excluding fuel, restructuring and impairment charges increased 0.4% as compared to the same period in 2004. As noted above, operating expense per ASM was also negatively impacted by the summer capacity reductions.
Explanations of significant period-over-period changes in the components of operating expenses are as follows:
    Wages and benefits decreased $22.8 million, or 5.6%, during the first six months of 2005 compared to the same period in 2004. Wages have been favorably impacted by the restructuring initiatives announced in August and September of 2004 and the reduction in pilot wages resulting from the arbitrator’s decision in May 2005. Additionally, during the second quarter of 2005, we subcontracted our ramp services operation in Seattle. During the first six months of 2005, there were 9,180 full-time equivalents (FTEs), which is down by 940 FTEs from 2004.
 
    Contracted services increased $6.9 million, or 13.1%, due largely to the contracting out of the Company’s fleet service and ground service equipment and facility maintenance in the fourth quarter of 2004, and the Seattle ramp operations in May 2005.
 
    Aircraft fuel increased $72.9 million, or 35.4%, due to a 36.5% increase in the GAAP fuel cost per gallon, offset by a 0.8% decrease in fuel gallons consumed. The increase in aircraft fuel expense is inclusive of $6.6 million of gains from settled hedges. During the first six months of 2005, Alaska also realized $37.0 million of gains from settled hedges, which are recorded in other non-operating income. After including all gains from settled hedges recorded during the period, our “economic,” or net, fuel expense increased $39.1 million, or 19.3%, over the same period in 2004. Our economic fuel cost per gallon increased 20.2% over the first six months of 2004 from $1.42 to $1.18.
 
      See page 23 for a table summarizing fuel cost per gallon realized by Alaska (the economic cost per gallon), the cost per gallon on a GAAP basis (including hedging gains recorded in aircraft fuel and non-operating income (expense)) and fuel cost per gallon excluding all hedging activities.
 
    Aircraft maintenance increased $16.1 million, or 19.1%, due largely to our power-by-the-hour maintenance agreement, whereby we expense B737-400 engine maintenance on a flight-hour basis, regardless of whether the work was actually performed during the period. Other factors causing the increase were the contracting out of related heavy maintenance to third parties, which resulted in a shift of costs from wages and benefits into aircraft maintenance, more airframe work and engine overhauls in 2005 compared to 2004, and the change in our accounting policy regarding engine and airframe overhauls (see Note 2 to our condensed consolidated financial statements).

34


Table of Contents

    Food and beverage service expense decreased $1.8 million, or 7.4%, due primarily to increased focus on cost reduction resulting in a decrease in average food and beverage cost per passenger.
 
    Other selling expenses and commissions decreased $1.3 million, or 2.0% due to a decline in advertising expense, offset by increases in commissions and codeshare fees.
 
    Depreciation and amortization decreased $2.2 million, or 3.5%. In the second quarter of 2004, we recorded an impairment charge of $36.8 million to reduce the carrying value of the Boeing 737-200C fleet, which results in lower depreciation expense in future periods. This is offset by the increased depreciation on two new owned aircraft delivered during the first six months of 2005.
 
    Landing fees and other rentals increased $12.6 million, or 18.4%. The higher rates reflect increased rental costs, primarily in Seattle, Portland and Los Angeles.
 
    Other expenses increased $4.1 million, or 5.4%, primarily reflecting increases in passenger remuneration costs, professional services costs, legal settlement costs and personnel and crew costs.
Horizon Air Revenues
For the first six months of 2005, operating revenues increased $26.8 million, or 11.4% compared to 2004. This increase is due largely to the increased traffic in the native network and the contract flying for Frontier Airlines, which began in January 2004, partially offset by a 4.7% decline in ticket yields.
For the six months ended June 30, 2005, capacity increased 9.9% and traffic was up 17.8%, compared to the same period in 2004, due to an increase in contract flying with Frontier, the addition of one CRJ 700 in March 2005 and four additional seats on each of our Q400’s. Contract flying with Frontier represented approximately 9.5% of passenger revenues and 22.4% of capacity, during the first half of 2005 compared to 8.6% and 19.5%, respectively, in the first six months of 2004. Passenger load factor increased 4.7 percentage points to 71.1%. Passenger yield decreased 4.7% to 21.95 cents, reflecting the inclusion of the Frontier contract flying, the yield for which is significantly lower than native network flying and an increase in average trip lengths across the native network, partially due to an increase in harmonization flying with Alaska. Passenger revenues increased by $27.7 million, or 12.2%, due primarily to the increase in traffic resulting from increased harmonization flying with Alaska and the increase in Frontier contract flying.
Horizon Air Expenses
Operating expenses for the first six months of 2005 increased $20.3 million, or 8.4%, compared to the same period in 2004. Operating expenses per ASM decreased 1.4% as compared to 2004. Operating expenses per ASM excluding fuel and impairment charges decreased 4.5% as compared to the same

Table of Contents

period in 2004. Operating expenses in 2004 include $2.8 million related to an impairment charge on our held-for-sale F-28 aircraft and spare engines to lower the carrying value of these assets to their estimated fair value.
Explanations of other significant period-over-period changes in the components of operating expenses are as follows:
    Wages and benefits increased $3.9 million, or 4.7%, reflecting a slight increase in the average number of employees, wages per employee, and a new performance-based incentive program for all employees, partially offset by favorable reductions of medical and workers compensation accruals.
 
    Aircraft fuel increased $12.6 million, or 41.7%, due to a 38.3% increase in the GAAP fuel cost per gallon from $1.24 in 2004 to $1.72 in 2005. The increase in aircraft fuel expense is inclusive of $0.8 million of gains from settled hedges. During the first six months of 2005, Horizon also realized $5.7 million of gains from settled hedges, which are recorded in other non-operating income (expense). After including all gains from settled hedges recorded during the period, our “economic,” or net, fuel expense increased $7.3 million, or 24.5%, over 2004. Our economic fuel cost per gallon increased 21.3% from $1.23 in 2004 to $1.49 in 2005.
 
      See page 24 for a table summarizing fuel cost per gallon realized by Horizon (the economic cost per gallon), the cost per gallon on a GAAP basis (including hedging gains recorded in aircraft fuel and non-operating income (expense)) and fuel cost per gallon excluding all hedging activities.
 
    Aircraft maintenance expense increased $2.5 million, or 15.0%, primarily due to a higher number of routine maintenance activities and engine overhauls for the Q200 and Q400 fleets and fewer aircraft covered by warranty. These increases are partially offset by the elimination of amortization expense on capitalized airframe and engine overhauls as a result of the accounting change in the first quarter of 2005 (see Note 2 to our condensed consolidated financial statements).
 
    Depreciation and amortization increased $1.6 million, or 25.4%, primarily due to the addition of one CRJ-700 at the end of the first quarter of 2005 and a Q400 in the third quarter of 2004.
 
    Landing fees and other rentals increased $3.3 million, or 16.3%. Higher landing fees are a result of significant rate increases in several of our key airports, modest volume growth and an increase in airport fees and increased costs for security.
Consolidated Nonoperating Income (Expense )
Net nonoperating income was $118.5 million for the first six months of 2005 compared to $12.2 million in the same period of 2004. Interest income increased $2.3 million due to a larger average marketable securities portfolio in 2005. Interest

36


Table of Contents

expense (net of capitalized interest) increased $2.6 million due to interest rate increases on our variable rate debt and the changes to some of our variable rate debt agreements to slightly higher fixed rate agreements.
Fuel hedging gains include $42.7 million in gains from fuel hedging contracts settled in the first six months of 2005 compared to $3.6 million in 2004. In addition, fuel hedging gains include net mark-to-market gains on unsettled hedge contracts of $93.0 million in 2005 and $22.8 million in 2004.
Consolidated Income Tax Expense (Benefit)
Accounting standards require us to provide for income taxes each quarter based on either our estimate of the effective tax rate for the full year or the actual year-to-date effective tax rate if it is our best estimate of our annual expectation. As the volatility of airfares and fuel prices and the seasonality of our business make it difficult to accurately forecast full-year pretax results, we use the actual year-to-date effective tax rate to provide for income taxes. In addition, a relatively small change in pretax results can cause a significant change in the effective tax rate due to the magnitude of nondeductible expenses, such as employee per diem costs, relative to pretax profit or loss. Our effective income tax rate on pre-tax income before the accounting change for the second quarter and first six months of 2005 is 41.4% and 41.5%, respectively. We applied our estimated 2005 year-to-date composite rate of 37.5% for the cumulative effect of the accounting change. In arriving at these rates, we considered a variety of factors, including year-to-date pretax results, the U.S. federal rate of 35%, estimated year-to-date nondeductible expenses and estimated state income taxes. We evaluate our tax rate each quarter and make adjustments when necessary.
Change in Accounting Policy
Effective January 1, 2005, the Company changed its method of accounting for major airframe and engine overhauls from the capitalize and amortize method to the direct expense method. Under the former method, these costs were capitalized and amortized to maintenance expense over the shorter of the life of the overhaul or the remaining lease term. Under the direct expense method, overhaul costs are expensed as incurred. The Company believes that the direct expense method is preferable because it eliminates the judgment and estimation needed to determine overhaul versus repair allocations in maintenance activities. Additionally, the Company’s approved maintenance program for the majority of its airframes now focuses more on shorter, but more frequent, maintenance visits. Management also believes that the direct expense method is the predominant method used in the airline industry. Accordingly, effective January 1, 2005, the Company wrote off the net book value of its previously capitalized airframe and engine overhauls for all aircraft in a charge totaling $144.7 million pre-tax ($90.4 million after tax). The Company does not believe disclosing the effect of adopting the direct expense method on net income for the period ended June 30, 2005 provides meaningful information because of changes in the Company’s maintenance program, including the execution of a “power by the hour” engine maintenance agreement with a third party in late 2004.

During the six months ended June 30, 2005, our cash and marketable securities decreased $147.8 million to $726.1 million at June 30, 2005. This decrease reflects cash used for property and equipment additions, net of aircraft deposit returns and proceeds from asset dispositions of $236.8 million and cash used in financing activities of $4.3 million, partially offset by cash provided by operating activities of $90.3 million.
Cash Provided by Operating Activities
During the first six months of 2005, net cash provided by operating activities was $90.3 million, compared to $188.8 million during the first six months of 2004. The decrease is due largely to the significant increases in the cost of fuel in the current year, cash payments made for severance, and a $42.7 million tax refund in 2004.
Cash Used in Investing Activities
Cash used in investing activities was $82.8 million during the first six months of 2005, compared to $128.0 million during the same period of 2004. We had net sales of marketable securities of $153.0 million and net purchases of $236.8 million for property and equipment additions, net of aircraft deposit returns and proceeds from asset dispositions. During the first six months of 2005, our aircraft related capital expenditures, net of aircraft deposit returns and proceeds from asset dispositions, increased $152.5 million as compared to 2004, primarily reflecting the purchase of two aircraft in the first six months of 2005 and the net payment of $101.2 million related to the aircraft purchase commitment entered into during the second quarter of 2005 to acquire 35 B737-800 aircraft. As of

38


Table of Contents

January 1, 2005, we no longer have capital expenditures related to overhauls as those maintenance activities are expensed as incurred under our maintenance accounting policy adopted on that date. We expect capital expenditures to be approximately $350.0 million for the full year of 2005 and approximately $430 million in 2006 as we begin to take delivery of several aircraft.
Cash Used in Financing Activities
Net cash used in financing activities was $4.3 million during the first six months of 2005 compared to $48.6 million during the same period in 2004. There was one debt issuance during the first half of 2005 of $20.0 million, which is secured by flight equipment. This note has a fixed interest rate of 6.07% and the payment term is 15 years. Debt issuances during the period were offset by normal long-term debt payments of $26.5 million.
We plan to meet our capital and operating commitments through cash flow from operations and from cash and marketable securities on hand at June 30, 2005 of $726.1 million. We also have restricted cash of $8.7 million, which is intended to collateralize interest payments due over the next nine months on our $150.0 million floating rate senior convertible notes due 2023 issued in 2003.
Bank Line of Credit Facility
During 2004, Alaska repaid its $150 million credit facility and, on December 23, 2004, that facility expired. On March 25, 2005, Alaska Airlines, Inc. finalized a $160 million variable rate credit facility with a syndicate of financial institutions that will expire in March 2008. The interest rate on the credit facility varies depending on certain financial ratios specified in the agreement with a minimum interest rate of LIBOR plus 200 basis points. Any borrowings will be secured by either aircraft or cash collateral. This credit facility contains contractual restrictions and requires maintenance of specific levels of net worth, maintenance of certain debt and leases to net worth, leverage and fixed charge coverage ratios, and limits on liens, asset dispositions, dividends, and certain other expenditures. Such provisions restrict Alaska Airlines from distributing any funds to Alaska Air Group in the form of dividends and limit the amount of funds Alaska Airlines can loan to Alaska Air Group. As of June 30, 2005, $300.0 million was available to loan to Alaska Air Group without violating the covenants in the credit facility. As of June 30, 2005, there are no outstanding borrowings on this credit facility and the Company has no immediate plans to borrow using this credit facility.
Supplemental Disclosure of Noncash Investing and Financing Activities
We received a $9.7 million credit toward our purchase deposits related to the recent aircraft purchase agreement entered into during the second quarter of 2005. This credit was recorded as additional purchase deposits and is included in other liabilities in our consolidated balance sheet and will be applied to future aircraft upon delivery.
Contractual Obligations, Commitments and Off-Balance Sheet Arrangements
Aircraft Purchase Commitments
At June 30, 2005, we had firm orders for 44 aircraft requiring aggregate payments of approximately $1.4 billion, as set forth below. In addition, Alaska has options to acquire 15 additional B737’s, and

39


Table of Contents

Horizon has options to acquire 11 Q400’s and 19 CRJ 700’s. Alaska and Horizon expect to finance the firm orders and, to the extent exercised, the option aircraft with leases, long-term debt or internally generated cash. The B737-800 delivered on July 1, 2005 was acquired with cash on hand.

New Accounting Standards
During the fourth quarter of 2004, the Financial Accounting Standards Board (FASB) issued SFAS 123R, “Share Based Payment: An Amendment of SFAS Nos. 123 and 95”. The new standard requires companies to recognize as expense the fair value of stock options and other equity based compensation issued to employees as of the grant date. This new standard will apply to both stock options that we grant to employees and our Employee Stock Purchase Plan, which features a look-back provision and allows employees to purchase stock at a 15% discount. Our options are typically granted with ratable vesting provisions, and we intend to amortize compensation cost over the service period using the straight line method. Due to a recent decision by the Securities and Exchange Commission, implementation of SFAS 123R will be effective January 1, 2006. We intend to use the “modified prospective method” upon adoption whereby previously awarded but unvested equity awards are accounted for in accordance with SFAS 123R and prospective amounts are recognized in the income statement instead of simply being disclosed. Once adopted, we expect our stock based compensation expense, as measured under SFAS 123R, will be approximately $6 million to $10 million per year on a pre-tax basis.
In March 2005, the FASB issued Interpretation No. 47 (FIN 47), “Accounting for Conditional Asset Retirement Obligations — an interpretation of FASB Statement No. 143.” FIN 47 clarifies that an entity is required to recognize a liability for the fair value of a conditional asset retirement obligation when incurred if the liability’s fair value can be reasonably estimated. The FIN also clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. FIN 47 is effective no later than the end of our fiscal year ending December 31, 2005. FIN 47 is not expected to have a significant impact on our financial position, results of operations or cash flows.
Effect of Inflation and Price Changes
Inflation and price changes other than for aircraft fuel do not have a significant effect on our operating revenues, operating expenses and operating income.
ITEM 3. Quantitative and Qualitative Disclosure about Market Risk
There have been no material changes in market risk from the information provided in Item 7A “Quantitative and Qualitative Disclosure About Market Risk” in our 2004 10K except as follows:
Fuel Hedging
We purchase jet fuel at prevailing market prices, and seek to manage the risk of price fluctuations through execution of a documented hedging strategy. We utilize derivative financial instruments as hedges to decrease our exposure to the volatility of jet fuel prices. At June 30, 2005, we had fuel hedge contracts in place to hedge 106.1 million gallons of our expected jet fuel usage during the remainder of 2005, 181.4 million gallons in 2006, 86.0 million gallons in 2007 and 31.7 million gallons in 2008. This represents 50%, 42%, 20% and 7% of our anticipated fuel consumption in 2005, 2006, 2007 and 2008, respectively. Prices of these agreements range from $29 to $50 per crude oil barrel.

41


Table of Contents

We estimate that a 10% increase or decrease in crude oil prices as of June 30, 2005 would impact hedging positions by approximately $39.0 million and $37.7 million, respectively.
As of June 30, 2005 and December 31, 2004, the fair values of our fuel hedge positions were $194.5 million and $96.0 million, respectively. Of these amounts, $123.6 million of the 2005 fair value amounts and $65.7 million of the 2004 fair value amounts were included in current assets in the consolidated balance sheets based on the settlement dates for the underlying contracts. The remaining $70.9 million 2005 fair value and $30.3 million 2004 fair value is reflected as a non-current asset in the consolidated balance sheets.
Please refer to pages 23 and 24, as well as to Note 4 in the condensed consolidated financial statements, for company specific data on the results of our fuel hedging program.
Financial Market Risk
During the first half of 2005, we issued $20.0 million of debt secured by flight equipment, having an interest rate of 6.07% and a payment term of 15 years.
In the second quarter of 2005, the Company exercised its option under several of its existing variable rate long-term debt arrangements to fix the interest rates through maturity. The fixed rates on these recently affected debt arrangements range from 5.2% to 6.3%. These changes did not result in any gain or loss in the consolidated statements of operations.
ITEM 4. Controls and Procedures
As of June 30, 2005, an evaluation was performed under the supervision and with the participation of our management, including our chief executive officer and chief financial officer (collectively, our “certifying officers”), of the effectiveness of the design and operation of our disclosure controls and procedures. These disclosure controls and procedures are designed to ensure that the information required to be disclosed by us in our periodic reports filed with the Securities and Exchange Commission (the SEC) is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms, and that the information is communicated to our certifying officers on a timely basis.
Our certifying officers concluded, based on their evaluation, that disclosure controls and procedures were effective.
We made no changes in our internal controls over financial reporting during the fiscal quarter ended June 30, 2005, that our certifying officers concluded materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
We intend to regularly review and evaluate the design and effectiveness of our disclosure controls and procedures and internal controls over financial reporting on an ongoing basis and to improve

42

these controls and procedures over time and to correct any deficiencies that we may discover in the future. While we believe the present design of our disclosure controls and procedures and internal controls over financial reporting are effective, future events affecting our business may cause us to modify our these controls and procedures in the future.
PART II. OTHER INFORMATION
ITEM 1. Legal Proceedings
In May 2005, the Air Line Pilots Association filed a lawsuit in federal district court in Seattle to overturn the current labor contract covering Alaska’s pilots as established by an arbitrator, which was effective May 1, 2005. If the arbitrator’s decision is overturned, Alaska may be required to pay wages retroactively to May 1, 2005 as if the contract that existed prior to the arbitrator’s decision were still in effect. On July 21, 2005, the Company filed a motion to dismiss the lawsuit. The motion will be decided on evidence submitted or following oral argument. A decision is expected in the third quarter of 2005. At this time, the Company has no reason to believe that an unfavorable outcome is likely.
In March 2005, the Company filed a claim against the International Association of Machinists (IAM) seeking to compel arbitration of the dispute regarding the subcontracting of the Company’s ramp service operation in Seattle. In May 2005, the IAM filed a counter claim against the Company alleging that the Company violated the status quo and engaged in bad faith bargaining. On May 13, 2005, the Company announced that it had subcontracted the ramp service operation in Seattle, resulting in the immediate reduction of approximately 475 employees represented by the IAM. Shortly after this event, the IAM filed a motion for a preliminary injunction seeking to reverse the subcontracting by the Company. That motion was heard and denied by a federal court judge on June 2, 2005. The Company’s lawsuit and the IAM’s counterclaim are still pending in federal court. A discovery schedule and trial date have not yet been set. At this time, the Company has no reason to believe that an unfavorable outcome is likely.
We are a party to ordinary routine litigation incidental to our business and with respect to which no material liability is expected. Management believes the ultimate disposition of these matters is not likely to materially affect our financial position or results of operations. This forward-looking statement is based on management’s current understanding of the relevant law and facts; it is subject to various contingencies, including the potential costs and risks associated with litigation and the actions of judges and juries.
ITEM 2. Unregistered Sales of Equity Securities and Use of Proceeds

Customer will have 30 days from receipt of such notice to elect to have Boeing manufacture a replacement aircraft under the same terms and conditions of purchase, except that the calculation of the Escalation Adjustment will be based upon the scheduled delivery month in effect immediately prior to the date of such notice, or, failing such election, the applicable purchase agreement will terminate with respect to such aircraft. Boeing will not be obligated to manufacture a replacement aircraft if reactivation of the production line for the specific model of aircraft would be required.

7.6 Termination. Termination under this Article will discharge all obligations and liabilities of Boeing and Customer with respect to any aircraft and all related undelivered Materials (as defined in Exhibit B, Customer Support Document), training, services, and other things terminated under the applicable purchase agreement, except that Boeing will return to Customer, without interest, an amount equal to all advance payments paid by Customer for the aircraft.

5.5 If Boeing agrees to make arrangements on behalf of Customer for the use of airports for flight training, Boeing will pay on Customer's behalf any landing fees charged by any airport used in conjunction with the flight training. At least 30 days before flight training, Customer will provide Boeing an open purchase order against which Boeing will invoice Customer for any landing fees Boeing paid on Customer's behalf. The invoice will be submitted to Customer approximately 60 days after flight training is completed, when all landing fee charges have been received and verified. Customer will pay to Boeing within 30 days of the date of the invoice.

5.6 If requested by Boeing, in order to provide the flight training or ferry flight assistance, Customer will make available to Boeing an aircraft after delivery to familiarize Boeing instructor or ferry flight crew personnel with such aircraft. If flight of the aircraft is required for any Boeing instructor or ferry flight crew member to maintain an FAA license for flight proficiency or landing currency, Boeing will be responsible for the costs of fuel, oil, landing fees and spare parts attributable to that portion of the flight.

5.7 If any part of the training described in Article 1.1 of this Exhibit is not used by Customer within 12 months after the delivery of the last aircraft under the relevant purchase agreement, Boeing will not be obligated to provide such training.

6.3 Boeing Claim Processing.

6.3.1 Any claim for a Boeing Product returned by Customer or its Authorized Agent to Boeing for Correction must accompany the Boeing Product. Any claim not associated with the return of a Boeing Product must be submitted signed and in writing directly by Customer or its Authorized Agent to Boeing Warranty by any of the methods identified in Article 11, "Notice," of the AGTA or through an internet portal and process specified by Boeing.

6.3.2 Boeing will promptly review the claim and will give notification of claim approval or rejection. If the claim is rejected, Boeing will provide a written explanation.

7. Corrections Performed by Customer or Its Authorized Agent.

7.1 Facilities Requirements. Provided Customer, its Authorized Agent or its third party contractor, as appropriate, are certified by the appropriate Civil Aviation Authority or Federal Aviation Authority, Customer or its Authorized Agent may, at its option, Correct defective Boeing Products at its facilities or may subcontract Corrections to a third party contractor.

7.2 Technical Requirements. All Corrections done by Customer, its Authorized Agent or a third party contractor must be performed in accordance with Boeing's applicable service manuals, bulletins or other written instructions, using parts and materials furnished or approved by Boeing.

7.3 Reimbursement.

7.3.1 Boeing will reimburse Customer's reasonable costs of Direct Materials and Direct Labor by credit memorandum (excluding labor hours expended for overhaul) at Customer's Warranty Labor Rate to Correct a defective Boeing Product. Claims for reimbursement must contain sufficient information to substantiate Direct Labor hours expended and Direct Materials consumed. Customer or its Authorized Agent may be required to produce invoices for materials.

7.3.2 Customer's established Warranty Labor Rate will be the greater of the standard labor rate or 150% of Customer's Average Direct Hourly Labor Rate. The standard labor rate paid by Boeing to its customers is established and published annually. Prior to or concurrently with submittal of Customer's first claim for Direct Labor reimbursement, Customer may notify Boeing of Customer's then-current Average Direct Hourly Labor Rate and thereafter notify Boeing of any material change in such rate. Boeing will require information from Customer to substantiate such rates.

            7.3.3 Reimbursement for Direct Labor hours to perform Corrections

stated in a service bulletin will be based on the labor estimates in the service bulletin.

7.3.4 Boeing will provide to Customer a single, lump sum credit memorandum for Customer's Direct Labor hours expended to incorporate the Corrections (other than of random anomalies) identified in service bulletins and service letters in all in-warranty aircraft covered by such service bulletins or service letters after Customer's submission of a warranty claim and verification of the incorporation of such Corrections with respect to the first affected in-warranty aircraft. Such credit memoranda will not be provided in response to any other requests for reimbursement including, without limitation, those arising out of program letters or other special offers provided by Boeing.

7.3.5 Boeing will reimburse Customer's freight charges associated with a Correction of a defect on a Boeing Product performed by its Authorized Agent or a third party contractor.

7.3.6 Maximum Reimbursement. Unless previously agreed in writing, the maximum reimbursement for Direct Labor and Direct materials for repair of a defective Boeing Product will not exceed 65% of Boeing's then-current sales price for a new replacement Boeing Product. Inspection, removal, reinstallation labor, final testing, inspection and transportation costs are separate and are not to be included in the cost elements used to determine the 65% limit. By mutual agreement between Customer and Boeing, Boeing may provide a replacement Product to Customer in lieu of credit reimbursement.

7.4 Disposition of Defective Boeing Products Beyond Economical Repair.

7.4.1 A defective Boeing Product found to be beyond economical repair (see Para. 7.3.6) will be retained for a period of 30 days from the date Boeing receives Customer's claim. During the 30 day period, Boeing may request return of such Boeing Products for inspection and confirmation of a defect.

7.4.2 After the 30 day period, a defective Boeing Product with a value of U.S. $4,000 or less may be scrapped without notification to Boeing. Boeing will reimburse Customer or its Authorized Agent for the charge for any item determined to be defective under this Aircraft General Terms Agreement. If such Boeing Product has a value greater than U.S, $4,000, Customer must obtain confirmation of unrepairability by Boeing's on-site Customer Services Representative prior to scrapping. Confirmation may be in the form of the Representative's signature on Customer's claim or through direct communication between the Representative and Boeing Warranty.

                                      2-7


8.1 Freight Charges. Customer or its Authorized Agent will pre-pay freight charges to return a Boeing Product to Boeing. If during the period of the applicable warranty Boeing determines the Boeing Product to be defective, Boeing will pre-pay shipping charges to return the Corrected Boeing Product. Boeing will reimburse Customer or its Authorized Agent for freight charges for Boeing Products returned to Boeing for Correction and determined to be defective.

8.2 Customer Instructions. The documentation shipped with the returned defective Boeing Product may include specific technical instructions for additional work to be performed on the Boeing Product. The absence of such instructions will evidence Customer's authorization for Boeing to perform all necessary Corrections and work required to return the Boeing Product to a serviceable condition.

8.3 Correction Time Objectives.

8.3.1 Boeing's objective for making Corrections is 10 working days for avionics and electronic Boeing Products, 30 working days for Corrections of other Boeing Products performed at Boeing's facilities and 40 working days for Corrections of other Boeing Products performed at a Boeing subcontractor's facilities. The objectives are measured from the date Boeing receives the defective Boeing Product and a valid claim to the date Boeing ships the Corrected Boeing Product.

8.3.2 If Customer has a critical parts shortage because Boeing has exceeded a Correction time objective and Customer has procured spare Boeing Products for the defective Boeing Product in quantities shown in Boeing's Recommended Spare Parts List or, for 717 model aircraft only, in quantities shown in Boeing's Spares Planning and Requirements Evaluation Model, then Boeing will either expedite the Correction or provide an interchangeable Boeing Product, on a no charge loan basis, until the Corrected Boeing Product is returned.

8.4 Title Transfer and Risk of Loss.

8.4.1 Title to and risk of loss of any Boeing Product returned to Boeing will at all times remain with Customer or any other title holder of such Boeing Product. While Boeing has possession of the returned Boeing Product, Boeing will have only such liabilities as a bailee for mutual benefit would have but will not be liable for loss of use.

8.4.2 If a Correction requires shipment of a new Boeing Product, then at the time Boeing ships the new Boeing Product, title to and risk of loss for the returned Boeing Product will pass to Boeing, and title to and risk of loss for the new Boeing Product will pass to Customer.

9. Returning an Aircraft.

                                      2-8


9.1 Conditions. An aircraft may be returned to Boeing's facilities for Correction only if:

(i) Boeing and Customer agree a covered defect exists;

(ii) Customer lacks access to adequate facilities, equipment or qualified personnel to perform the Correction; and

(iii) it is not practical, in Boeing's estimation, to dispatch Boeing personnel to perform the Correction at a remote site.

9.2 Correction Costs. Boeing will perform the Correction at no charge to Customer. Subject to the conditions of Article 9.1, Boeing will reimburse Customer for the costs of fuel, oil, other required fluids and landing fees incurred in ferrying the aircraft to Boeing and back to Customer's facilities. Customer will minimize the length of both flights.

9.3 Separate Agreement. Prior to the return of an aircraft to Boeing, Boeing and Customer will enter into a separate agreement covering return of the aircraft and performance of the Correction. Authorization by Customer for Boeing to perform additional work that is not part of the Correction must be received within 24 hours of Boeing's request. If such authorization is not received within 24 hours, Customer will be invoiced for work performed by Boeing that is not part of the Correction.

10. Insurance.

The provisions of Article 8.2 "Insurance", of this AGTA, will apply to any work performed by Boeing in accordance with Customer's specific technical instructions to the extent any legal liability of Boeing is based upon the content of such instructions.

11. Disclaimer and Release; Exclusion of Liabilities.

(ii) For all other aircraft models:

P = CT

144

where:

P = price to Customer for the replacement part

C = SLP Component sales price at time of replacement

T = total age in months of the failed SLP Component from the date of delivery to Customer to the date of discovery of such condition.

4. Conditions.

Boeing's obligations under this Part 3 of Exhibit C, "Boeing Service Life Policy," (Policy) are conditioned upon the following:

4.1 Customer must notify Boeing in writing of the failure within three months after it is discovered.

(i) a defect or failure in a component not covered by this Policy,

(ii) an extrinsic force,

(iii) an act or omission of Customer, or

(iv) operation or maintenance contrary to applicable governmental regulations or Boeing's instructions.

PART 5: BOEING INTERFACE COMMITMENT

1. Interface Problems.

An Interface Problem is defined as a technical problem in the operation of an aircraft or its systems experienced by Customer, the cause of which is not readily identifiable by Customer but which Customer believes to be attributable to either the design characteristics of the aircraft or its systems or the workmanship used in the installation of Supplier Products. In the event Customer experiences an Interface Problem, Boeing will, without additional charge to Customer, promptly conduct an investigation and analysis to determine the cause or causes of the Interface Problem. Boeing will promptly advise Customer at the conclusion of its investigation of Boeing's opinion as to the causes of the Interface Problem and Boeing's recommendation as to corrective action.

2. Boeing Responsibility.

If Boeing determines that the Interface Problem is primarily attributable to the design or installation of any Boeing Product, Boeing will Correct the design or workmanship to the extent of any then-existing obligations of Boeing under the provisions of the applicable Boeing Warranty.

3. Supplier Responsibility.

If Boeing determines that the Interface Problem is primarily attributable to the design or installation of a Supplier Product, Boeing will assist Customer in processing a warranty claim against the Supplier.

4. Joint Responsibility.

If Boeing determines that the Interface Problem is partially attributable to the design or installation of a Boeing Product and partially to the design or installation of a Supplier Product, Boeing will seek a solution to the Interface Problem through the cooperative efforts of Boeing and the Supplier and will promptly advise Customer of the resulting corrective actions and recommendations.

5. General.

Customer will, if requested by Boeing, assign to Boeing any of its rights against any supplier as Boeing may require to fulfill its obligations hereunder.

ESCALATION ADJUSTMENT

AIRFRAME AND OPTIONAL FEATURES

between

THE BOEING COMPANY

and

ALASKA AIRLINES, INC.

Supplemental Exhibit AE1 to Purchase Agreement Number 2497

BOEING PROPRIETARY


1. Alternate Escalation Formula

Airframe and Optional Features price adjustments (Airframe Price Adjustment) are used to allow prices to be stated in current year dollars at the signing of this Purchase Agreement and to adjust the amount to be paid by Customer at delivery for the effects of economic fluctuation. The Airframe Price Adjustment will be determined at the time of Aircraft delivery in accordance with the following formula:

P(a) =(P)(L + M) - P

Where:

P(a) = Airframe Price Adjustment.

       (for the 737-800 Aircraft the Airframe Price includes
       the Engine Price at its basic thrust level)

L =    .65 x ( ECI
             -------
             ECI(b))  where ECI(b) is the base year index
                      (as set forth in Table 1 of this
                      Purchase Agreement)

M =    .35 x ( CPI
             -------
             CPI(b))  where CPI(b) is the base year index (as
                      set forth in Table 1 of this Purchase
                      Agreement)

P = Airframe Price plus Optional Features Price (as set forth in Table 1 of this Purchase Agreement).

ECI is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics Employment Cost Index Manufacturing
- Total Compensation (BLS Series ID ECU12402I), calculated by establishing a three-month arithmetic average value (expressed as a decimal and rounded to the nearest tenth) using the values for the 11th, 12th and 13th months prior to the month of scheduled delivery of the applicable Aircraft. As the Employment Cost Index values are only released on a quarterly basis, the value released for the month of March will be used for the months of January and February; the value for June used for April and May; the value for September used for July and August; and the value for December used for October and November.

CPI is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics Consumer Price Index (BLS Series ID

BOEING PROPRIETARY


CUUR0000SA0), calculated as a 3-month arithmetic average of the released monthly values (expressed as a decimal and rounded to the nearest tenth) using the values for the 11th, 12th and 13th months prior to the month of scheduled delivery of the applicable Aircraft.

As an example, for an Aircraft scheduled to be delivered in the month of July, the months June, July and August of the preceding year will be utilized in determining the value of ECI and CPI.

Note: i. In determining the values of L and M, all calculations and resulting values will be expressed as a decimal rounded to the nearest ten-thousandth.

ii. .65 is the numeric ratio attributed to labor in the Airframe Price Adjustment formula.

iii. .35 is the numeric ratio attributed to materials in the Airframe Price Adjustment formula.

iv. The denominators (base year indices) are the actual average values reported by the U.S. Department of Labor, Bureau of Labor Statistics. The actual average values are calculated as a 3-month arithmetic average of the released monthly values (expressed as a decimal and rounded to the nearest tenth) using the values for the 11th, 12th and 13th months prior to the airframe base year. The applicable base year and corresponding denominator is provided by Boeing in Table 1 of this Purchase Agreement.

v. The final value of P(a) will be rounded to the nearest dollar.

vi. The Airframe Price Adjustment will not be made if it will result in a decrease in the Aircraft Basic Price.

2. Values to be Utilized in the Event of Unavailability.

2.1 If the Bureau of Labor Statistics substantially revises the methodology used for the determination of the values to be used to determine the ECI and CPI values (in contrast to benchmark adjustments or other corrections of previously released values), or for any reason has not released values needed to determine the applicable Airframe Price Adjustment, the parties will, prior to the delivery of any such Aircraft, select a substitute from other Bureau of Labor Statistics data or similar data reported by non-governmental organizations. Such substitute will result in the same adjustment, insofar as possible, as would have been calculated utilizing the original values adjusted for fluctuation during the applicable time period. However, if within 24 months after delivery of the Aircraft, the Bureau of Labor Statistics should resume releasing values for the months needed to determine the Airframe Price Adjustment; such values will be used to determine any increase or decrease in the Airframe Price Adjustment for the Aircraft from that determined at the time of delivery of the Aircraft.

BOEING PROPRIETARY


2.2 Notwithstanding Article 2.1 above, if prior to the scheduled delivery month of an Aircraft the Bureau of Labor Statistics changes the base year for determination of the ECI and CPI values as defined above, such re-based values will be incorporated in the Airframe Price Adjustment calculation.

2.3 In the event escalation provisions are made non-enforceable or otherwise rendered void by any agency of the United States Government, the parties agree, to the extent they may lawfully do so, to equitably adjust the Aircraft Price of any affected Aircraft to reflect an allowance for increases or decreases consistent with the applicable provisions of paragraph 1 of this Supplemental Exhibit AE1 in labor compensation and material costs occurring since August of the year prior to the price base year shown in the Purchase Agreement.

2.4 If within 12 months of Aircraft delivery, the published index values are revised due to an acknowledged error by the Bureau of Labor Statistics, the Airframe Price Adjustment will be re-calculated using the revised index values (this does not include those values noted as preliminary by the Bureau of Labor Statistics). A credit memorandum or supplemental invoice will be issued for the Airframe Price Adjustment difference that results from the revised index values for the delivered Aircraft. Customer may elect that the credit or supplemental invoice be applied against the applicable delivered Aircraft, the next Aircraft to deliver, or to goods and services. The adjustment though added to the invoice of the next Aircraft to deliver will continue to relate to the delivered Aircraft. Interest charges will not apply for the period of original invoice to issuance of credit memorandum or supplemental invoice.

Note: i. The values released by the Bureau of Labor Statistics and available to Boeing 30 days prior to the first day of the scheduled delivery month of an Aircraft will be used to determine the ECI and CPI values for the applicable months (including those noted as preliminary by the Bureau of Labor Statistics) to calculate the Airframe Price Adjustment for the Aircraft invoice at the time of delivery. The values will be considered final and no Airframe Price Adjustments will be made after Aircraft delivery for any subsequent changes in published Index values, subject always to paragraph 2.4 above.

ii. The maximum number of digits to the right of the decimal after rounding utilized in any part of the Airframe Price Adjustment equation will be 4, where rounding of the fourth digit will be increased to the next highest digit when the 5th digit is equal to 5 or greater.

Subject: Aircraft Model Substitution

Reference: Purchase Agreement No. 2497 (the Purchase Agreement) between The Boeing Company (Boeing) and Alaska Airlines, Inc. (Customer) relating to Model 737-890 aircraft (the Aircraft)

This letter agreement (Letter Agreement) amends and supplements the Purchase Agreement. All terms used but not defined in this Letter Agreement have the same meaning as in the Purchase Agreement.

Customer may substitute the purchase of Boeing Model 737-900X aircraft (737-900X SUBSTITUTE AIRCRAFT) in place of any of the Aircraft, subject to the following terms and conditions:

1. 737-900X Offering.

Boeing's offer of the 737-900X Substitution Aircraft proposed herein is subject to Boeing's decision to launch the 737-900X Aircraft. Based on Boeing's launching the 737-900X Aircraft, Boeing may use up to two (2) of the 737-900X Substitution Aircraft prior to delivery for flight and ground testing relating to the development and certification. The parties shall mutually agree upon any special terms related to use of any Substitution Aircraft for flight and ground testing.

2. Customer's Written Notice.

Customer will provide written notice of its intention to substitute the purchase of an Aircraft with the purchase of a Substitute Aircraft,

(a) no later than the first day of the month that is fifteen (15) months prior to the scheduled month of delivery of the Aircraft for which it will be substituted, provided that a 737-900X Substitute Aircraft has been previously certified and delivered to Customer, or;

P.A. No. 2497

BOEING PROPRIETARY


Alaska Airlines, Inc.
2497-2 Page 2

(b) no later than the first day of the month that is twenty-four (24) months prior to the scheduled month of delivery of the Aircraft for which it will be substituted, if a 737-900X Substitute Aircraft has been made offerable but has not been previously certified and delivered to Customer.

2. Boeing's Production Capability.

Customer's substitution right is conditioned upon Boeing's having production capability for the 737-900X Substitute Aircraft in the scheduled delivery month of the Aircraft for which it will be substituted.

If offerable, Boeing will tentatively quote delivery positions for 737-900X Substitute Aircraft to allow Customer to secure quotes from Buyer Furnished Equipment vendors, and Boeing to secure quotes from Seller Furnished Equipment vendors which supports the required on-dock dates. If Boeing is unable to manufacture the 737-900X Substitute Aircraft in the scheduled delivery month of the Aircraft for which it will be substituted, then Boeing shall promptly make a written offer of an alternate delivery month for Customer's consideration and written acceptance within thirty (30) days of such offer.

3. Definitive Agreement.

Customer's substitution right and Boeing's obligation in this Letter Agreement are further conditioned upon Customer's and Boeing's executing a definitive agreement for the purchase of the 737-900X Substitute Aircraft within thirty
(30) days of Customer's substitution notice to Boeing or of Customer's acceptance of an alternate delivery month in accordance with paragraph 2. above.

4. Price, Escalation Adjustments and Advance Payments.

The Airframe Price and the price of Optional Features will be adjusted to Boeing's then-current prices for such elements as of the date of execution of the definitive purchase agreement for the 737-900X Substitute Aircraft. The Airframe Price and the price of Optional Features for 737-900X Substitute Aircraft will be escalated using 1) Boeing's standard escalation provisions (ECI-W formula) or alternate escalation provisions (ECI-MFG/CPI formula) to be selected by Customer at the date of execution of the definitive agreement for the 737-900X Substitution Aircraft, or 2) a different Boeing then current escalation provisions should such exist at the date of execution of the definitive agreement for the 737-900X Substitution Aircraft. The representative escalation indices and methodology will be used to estimate the Advance Payment Base Prices for 737-900X Substitution Aircraft.

If the Advance Payment Base Price for any 737-900X Substitute Aircraft is higher than that of the Aircraft, Customer will pay to Boeing the amount of the difference

P.A. No. 2497
Aircraft_Model_Substitution

BOEING PROPRIETARY


Alaska Airlines, Inc.
2497-2 Page 3

as of the date of execution of the definitive agreement for the 737-900X Substitute Aircraft. If the Advance Payment Base Price of the 737-900X Substitute Aircraft is lower than that of the Aircraft, Boeing will retain any excess amounts previously paid by Customer until the next payment is due from Customer, at which point Customer may reduce the amount of such payment by the amount of the excess. In no case will Boeing refund or pay interest on any excess amounts created by virtue of Customer's exercise of the rights of substitution described in this agreement.

5. Confidential Treatment.

Customer understands that certain commercial and financial information contained in this Letter Agreement are considered by Boeing as confidential. Customer agrees that it will treat this Letter Agreement and the information contained herein as confidential and will not, without the prior written consent of Boeing, disclose this Letter Agreement or any information contained herein to any other person or entity.

Subject: Demonstration Flight Waiver

Reference: Purchase Agreement No. 2497 (the Purchase Agreement) between The Boeing Company (Boeing) and Alaska Airlines, Inc. (Customer) relating to Model 737-890 aircraft (the Aircraft)

This letter agreement (Letter Agreement) amends and supplements the Purchase Agreement. All terms used but not defined in this Letter Agreement shall have the same meaning as in the Purchase Agreement.

Definition of Terms:

CORRECTION COSTS: Customer's direct labor costs and the cost of any material required to correct a Flight Discrepancy where direct labor costs are equal to the warranty labor rate in effect between the parties at the time such labor is expended.

FLIGHT DISCREPANCY: A failure or malfunction of an Aircraft, or the accessories, equipment or parts installed on the Aircraft which results from a defect in the Aircraft, Boeing Product, engine or Supplier Product or a nonconformance to the Detail Specification for the Aircraft.

The AGTA provides that each aircraft will be test flown prior to delivery for the purpose of demonstrating the functioning of such Aircraft and its equipment to Customer; however, Customer may elect to waive this test flight. For each test flight waived, Boeing agrees to provide Customer an amount of jet fuel at delivery that, including the standard fuel entitlement, totals the following amount of fuel:

AIRCRAFT                   TOTAL FUEL ENTITLEMENT
 MODEL                          (U.S. GALLONS)
--------           -----------------------------------
  737              Full tanks (approx. 5,300 to 6,800,
                          depending on model)

Further, Boeing agrees to reimburse Customer for any Correction Costs incurred as a result of the discovery of a Flight Discrepancy during the first flight of the aircraft by Customer following delivery to the extent such Correction Costs are

P.A. No. 2497
Demonstration_Flight_Waiver

BOEING PROPRIETARY


Alaska Airlines, Inc.
2497-4 Page 2

not covered under a warranty provided by Boeing, the engine manufacturer or any of Boeing's suppliers.

Should a Flight Discrepancy be detected by Customer which requires the return of the Aircraft to Boeing's facilities at Seattle, Washington, so that Boeing may correct such Flight Discrepancy, Boeing and Customer agree that title to and risk of loss of such Aircraft will remain with Customer. In addition, it is agreed that Boeing will have responsibility for the Aircraft while it is on the ground at Boeing's facilities in Seattle, Washington, as is chargeable by law to a bailee for mutual benefit, but Boeing shall not be chargeable for loss of use.

To be reimbursed for Correction Costs, Customer shall submit a written itemized statement describing any flight discrepancies and indicating the Correction Cost incurred by Customer for each discrepancy. This request must be submitted to Boeing's Contracts Regional Director at Renton, Washington, within ninety (90) days after the first flight by Customer.

                         above the departure airport altitude and retracting
                         flaps and landing gear.

      Climb:             The Aircraft climbs from [***] feet above the departure
                         airport altitude to [***] feet altitude at [***] KCAS.

                         The Aircraft then accelerates at a rate of climb of
                         [***] feet per minute to a climb speed of [***] KCAS.

                         The climb continues at [***] KCAS until 0.78 Mach
                         number is reached.

                         The climb continues at 0.78 Mach number to the initial
                         cruise altitude.

                         The temperature is standard day during climb.

                         Maximum climb thrust is used during climb.

(1) Changes to the Detail Specification or any other changes mutually agreed upon between the Customer and Boeing or otherwise allowed by the Purchase Agreement.

(2) The difference between the component weight allowances given in Appendix IV of the Detail Specification and the actual weights.

6 GUARANTEE CONDITIONS

6.1 All guaranteed performance data are based on the International Standard Atmosphere (ISA) and specified variations therefrom; altitudes are pressure altitudes.

6.2 The FAA Regulations (FAR) referred to in this Attachment are, unless otherwise specified, the 737-800 Certification Basis regulations specified in the Type Certificate Data Sheet A16WE, Revision 33, dated March 8, 2002.

6.3 In the event a change is made to any law, governmental regulation or requirement, or in the interpretation of any such law, governmental regulation or requirement that affects the certification basis for the Aircraft as described in Paragraphs 4.1 or 6.2, and as a result thereof, a change is made to the configuration and/or the performance of the Aircraft in order to obtain certification, the guarantees set forth in this Attachment shall be appropriately modified to reflect any such change.

6.4 The takeoff and landing guarantees, and the takeoff portion of the mission guarantee are based on hard surface, level and dry runways with no wind or obstacles, no clearway or stopway, 225 mph tires, with Category C brakes and anti-skid operative, and with the Aircraft center of gravity at the most forward limit unless otherwise specified. The takeoff performance is based on no engine bleed for air conditioning or thermal anti-icing and the Auxiliary Power Unit (APU) turned off unless otherwise specified. Unbalanced field length calculations and the improved climb performance procedure will be used for takeoff as required. The landing performance is based on the use of automatic spoilers.

Page 11

6.5 The climb, cruise, and descent portions of the mission guarantee include allowances for normal power extraction and engine bleed for normal operation of the air conditioning system. Normal electrical power extraction shall be defined as not less than a 50 kilowatts total electrical load. Normal operation of the air conditioning system shall be defined as pack switches in the "Auto" position, the temperature control switches in the "Auto" position that results in a nominal cabin temperature of 75(degrees)F, and all air conditioning systems operating normally. This operation allows a maximum cabin pressure differential of 8.35 pounds per square inch at higher altitudes, with a nominal Aircraft cabin ventilation rate of 3,300 cubic feet per minute including passenger cabin recirculation (nominal recirculation is 47 percent). The APU is turned off unless otherwise specified.

6.6 The climb, cruise and descent portions of the mission guarantee are based on an Aircraft center of gravity location of 26.2 percent of the mean aerodynamic chord.

6.7 Performance, where applicable, is based on a fuel Lower Heating Value (LHV) of 18,580 BTU per pound and a fuel density of 6.7 pounds per U.S. gallon.

7 GUARANTEE COMPLIANCE

7.1 Compliance with the guarantees of Sections 2, 3 and 4 shall be based on the conditions specified in those sections, the Aircraft configuration of
Section 5 and the guarantee conditions of Section 6.

7.2 Compliance with the takeoff and landing guarantees, the takeoff portion of the mission guarantee, and the community sound level guarantees shall be based on the FAA approved Airplane Flight Manual for the Model 737-800.

7.3 Compliance with the climb, cruise, and descent portions of the mission guarantee shall be established by calculations based on flight test data obtained from an aircraft in a configuration similar to that defined by the Detail Specification.

7.5 Compliance with the Manufacturer's Empty Weight guarantee shall be based on information in the "Weight and Balance Control and Loading Manual - Aircraft Report."

7.6 The data derived from tests shall be adjusted as required by conventional methods of correction, interpolation or extrapolation in accordance with established engineering practices to show compliance with these guarantees.

7.7 Compliance with the single event noise exposure level guarantee of Paragraphs 4.2.1 will be by calculations made by Boeing using standard engineering practices with noise information measured by Boeing using the Model 737-700 with CFM56-7B (SAC) engines. The noise calculation process will be as follows:

7.7.1 Noise (dBA) time histories for a range of brake release gross weights (BRGW) for the model 737-800W with CFM56-7B26 (SAC) engines will be calculated by combining full power takeoff and cutback dBA time histories from noise data measured at the noise certification test of May 1997. Adjustments will be appropriate to simulate the takeoff procedure described in Paragraph 4.2.2. These dBA time histories will then be integrated as described in CALIFORNIA NOISE STANDARDS (California Administrative Code, Title 21, Chapter 2.5, Sub-Chapter 6, effective January 1, 1986, Division of Aeronautics (Department of Transportation)), except that the threshold noise level will be 65 dBA as used at SNA for noise monitors M1 and M2 to calculate SENEL at each BRGW.

7.7.2 Curve fits of SENEL vs. BRGW will then be developed for noise monitors M1 and M2, using the data derived in Paragraph 7.7.1.

7.7.3 The SENEL versus BRGW curve fit of Paragraph 7.7.2 will then be entered at the noise limits of 93.5 dB SENEL for microphone location M1 and 93.0 dB SENEL for microphone location M2, respectively, to determine weights that correspond to the expected quarterly average weight capability of the Aircraft. These weights will be compared to the guarantee weight of Paragraph 4.2.1 to determine compliance with that guarantee.

7.7.4 A document will be prepared by Boeing to show compliance with the single event noise exposure level guarantees of Paragraph 4.2.
