Notes to Condensed Consolidated Financial Statements
(unaudited)

1. Basis of presentation - The accompanying unaudited condensed consolidated financial statements of Southwest Airlines Co. (Company) have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. The condensed consolidated financial statements for the interim periods ended September 30, 2000 and 1999 include all adjustments (which include only normal recurring adjustments) which are, in the opinion of management, necessary for a fair presentation of the results for the interim periods. Operating results for the three and nine month periods ended September 30, 2000 are not necessarily indicative of the results that may be expected for the year ended December 31, 2000. For further information, refer to the consolidated financial statements and footnotes thereto included in the Southwest Airlines Co. Annual Report on Form 10-K for the year ended December 31, 1999.

2. Dividends - During the three month periods ended September 30, 2000, June 30, 2000, and March 31, 2000, dividends of $.0055 per share were declared on the 499.6 million, 497.7 million, and 497.1 million shares of common stock then outstanding, respectively. During the three month periods ended September 30, 1999 and June 30, 1999, dividends of $.0055 per share were declared on the 504.1 million and 503.6 million shares of common stock then outstanding, respectively. During the three month period ended March 31, 1999, dividends of $.005 per share were declared on the 501.9 million shares of common stock then outstanding.

3. Reclassifications - Certain prior year amounts have been reclassified to conform to the current year presentation. Most notably, this includes the reclassification of $14.7 million and $46.9 million for the three months and nine months ended September 30, 1999, respectively, of "Other revenue" to "Passenger revenue" as a result of the change in accounting principle effective January 1, 2000. See Note 5 for further information.

4. Net income per share - The following table sets forth the computation of basic and diluted net income per share (in thousands except per share amounts):

5. Accounting Change - Effective January 1, 2000, the Company adopted Staff Accounting Bulletin 101 (SAB 101) issued by the Securities and Exchange Commission in December 1999. As a result of adopting SAB 101, the Company changed the way it recognizes revenue from the sale of flight segment credits to companies participating in its Rapid Rewards frequent flyer program. Prior to the issuance of SAB 101, the Company recorded revenue to "Other revenue" when flight segment credits were sold, consistent with most other major airlines. Beginning January 1, 2000, the Company recognizes "Passenger revenue" when free travel awards are earned and flown. Due to this change, the Company recorded a cumulative adjustment in first quarter 2000 of $22.1 million (net of income taxes of $14.0 million) or $.04 per share, basic and diluted. The third quarter 2000 impact of adopting SAB 101 was to reduce net income by $1.8 million. Excluding the impact of the change, basic and diluted net income per share for third quarter 2000 would have been $.37 and $.35, respectively. The Company also reclassified for comparison purposes the revenue reported in prior periods related to the sale of flight segment credits from "Other revenue" to "Passenger revenue."

6. Recently issued accounting standards - In 1998, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 133 (SFAS 133), Accounting for Derivative Instruments and Hedging Activities. In 1999, the FASB issued SFAS 137, which delayed the effective date of SFAS 133 by one year. In June 2000, the FASB issued SFAS 138, which further amended SFAS 133. SFAS 133 is required to be adopted in years beginning after June 15, 2000. The Company expects to adopt SFAS 133 effective January 1, 2001. SFAS 133 will require the Company to record all derivatives on the balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income. If the derivative is designated as a hedge, depending on the nature of the hedge, changes in the fair value of derivatives will be either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings or recorded in other comprehensive income until the hedged item is recorded in earnings. The ineffective portion of a derivative's change in fair value will be immediately recorded in earnings. The Company currently believes it will have all appropriate documentation in place as required by SFAS 133 and will be ready to complete the transition to SFAS 133 on January 1, 2001. The Company currently intends to account for its fuel hedge derivative instruments as cash flow hedges, as defined. Although the fair value of the Company's derivative instruments fluctuates daily, as of September 30, 2000, the Company has estimated the fair value of its off-balance sheet fuel hedge derivative instruments for periods subsequent to January 1, 2001 to be approximately $140 million. Under SFAS 133, this amount would have to be recorded as an asset on the Company's balance sheet. The Company believes the majority of the offset to this balance sheet adjustment would be an increase to other comprehensive income, a component of stockholders equity. Any difference between these amounts would be recorded as a cumulative effect of accounting adjustment on the Company's statement of income. The cumulative effect adjustment would represent any ineffectiveness from the Company's hedge positions, including items such as changes in time value that can be excluded in tests of effectiveness. The Company believes, upon the adoption of SFAS 133, more volatility may be incurred in its financial statements than in the past.

Material Changes in Results of Operations

Comparison of Three Months Ended September 30, 2000 to Three Months Ended September 30, 1999

Consolidated net income for the third quarter ended September 30, 2000 was $184.3 million, an increase of 45.1 percent compared to 1999. Diluted net income per share was $.35 compared to $.24 in 1999. Operating income for third quarter 2000 was $300.1 million, an increase of 45.4 percent compared to 1999.

Third quarter 2000 consolidated operating revenues increased 19.7 percent primarily due to a 20.2 percent increase in passenger revenues. The increase in passenger revenues primarily resulted from the Company's increased capacity, strong demand for commercial air travel, and excellent revenue management. The Company also benefited due to operational difficulties experienced by several airline competitors. Although the Company cannot precisely quantify this benefit, we believe the basic demand for our low fare service remained strong for third quarter 2000. The Company experienced a 10.5 percent increase in revenue passengers carried, a 14.1 percent increase in RPMs, and a 5.3 percent increase in passenger revenue yield per RPM (passenger yield). The increase in passenger yield is primarily due to an 8.8 percent increase in average passenger fare, partially offset by a 3.3 percent increase in average length of passenger haul.

The increase in RPMs exceeded the 12.4 percent increase in ASMs resulting in a load factor of 71.6 percent, or 1.0 points above third quarter 1999. The increase in ASMs resulted primarily from the net addition of 28 aircraft since third quarter 1999, which represents a 9.2 percent increase in the Company's fleet size. Thus far, load factors in October have exceeded those experienced in October 1999. Bookings for November and December are also good and we presently anticipate positive year over year unit revenue comparisons again in fourth quarter 2000. (The immediately preceding two sentences are forward-looking statements, which involve uncertainties that could result in actual results differing materially from expected results. Some significant factors include, but may not be limited to, competitive pressure such as fare sales and capacity changes by other carriers, general economic conditions, and variations in advance booking trends.)

Consolidated freight revenues increased 10.5 percent primarily due to an increase in capacity. Other revenues, which consist primarily of charter revenues, increased 3.2 percent. This increase was less than the Company's increase in capacity primarily due to the Company's decision to use more of its aircraft to satisfy the strong demand for scheduled service and, therefore, make fewer aircraft available for charters.

Operating expenses per ASM increased 2.0 percent to $.0770, compared to $.0755 for third quarter 1999, primarily due to an increase in average jet fuel prices. The average fuel cost per gallon was 27.0 percent higher than third quarter 1999's average cost per gallon. Excluding fuel expense, operating expenses per ASM decreased 1.2 percent. As detailed below, the Company has hedges in place for all of its anticipated fuel consumption in fourth quarter 2000 at prices well below market prices as of October 25, 2000. Including estimated hedging gains and taking into account current market prices, we are forecasting our fourth quarter 2000 average fuel cost to be in the $.80 range per gallon, which would exceed fourth quarter 1999's average cost of $.67 per gallon. Excluding fuel, the Company expects slightly lower unit costs in fourth quarter 2000 versus 1999. (The immediately preceding two sentences are forward-looking statements which involve uncertainties that could result in actual results differing materially from expected results. Such uncertainties include, but may not be limited to, the largely unpredictable levels of jet fuel prices and the Company's ability to control its non-fuel costs.)

Salaries, wages, and benefits per ASM increased slightly as an increase in average wage rates was partially offset by an increase in productivity in several of the Company's operational areas. Profitsharing and Employee savings plan expenses per ASM increased 18.4 percent, primarily due to the increase in Company earnings available for profitsharing.

Fuel and oil expense per ASM increased 21.0 percent due to a 27.0 percent increase in the average jet fuel cost per gallon compared to 1999. The average price paid for jet fuel in third quarter 2000 was $.7412 per gallon compared to $.5836 in 1999, including the effects of hedging activities. The Company's third quarter 2000 and 1999 average jet fuel prices are net of approximately $43.1 million and $2.5 million in gains from hedging activities, respectively. As of October 25, 2000, the Company had crude oil and/or heating oil hedge positions in place for 2000 and 2001 as follows:

                    Type      Average underlying       Approximate percentage
                  of hedge    price of crude oil       of expected jet fuel

As of October 25, 2000, the unrealized gains from these hedging activities were $64.6 million for fourth quarter 2000 and approximately $133.4 million for all of 2001. The majority of the Company's crude oil hedge positions in the above table have been converted to heating oil hedges. Heating oil prices have historically correlated more closely with jet fuel prices than has the price of crude oil. Despite these hedge positions, the Company is expecting higher average net jet fuel cost per gallon for fourth quarter 2000 compared to fourth quarter 1999. The Company's fuel hedging strategy could result in the Company not fully benefiting from lower jet fuel prices should crude oil and/or heating oil prices decline below prices implicit in the hedge instruments. (The immediately preceding two sentences are forward-looking statements, which involve uncertainties that could result in actual results differing materially from expected results. Such uncertainties include, but may not be limited to, the largely unpredictable levels of jet fuel prices.)

Maintenance materials and repairs per ASM decreased 11.0 percent primarily due to a decrease in engine maintenance related to its 737-200 aircraft fleet, as 1999 was an unusually high period for engine maintenance on these aircraft. The engines on these aircraft are not covered by the Company's "power-by-the-hour" maintenance contract with General Electric Engine Services, Inc.; therefore, repairs are expensed on a time and materials basis. These engine repairs represented approximately 59 percent of the total decrease, while a decrease in airframe inspections and repairs per ASM represented approximately 16 percent of the total decrease. The Company also expects maintenance materials and repairs expense per ASM to be lower in fourth quarter 2000 than the comparable 1999 period due to a decrease in scheduled engine maintenance on 737-200 aircraft, although not as much of a decrease as third quarter 2000. (The immediately preceding sentence is a forward-looking statement that involves uncertainties that could result in actual results differing materially from expected results. Such uncertainties include, but may not be limited to any unanticipated required aircraft airframe or engine repairs.)

Agency commissions per ASM decreased 6.9 percent, primarily due to an increase in direct sales. In third quarter 2000, approximately 30 percent of the Company's revenues were attributable to direct bookings through the Company's Internet site compared to approximately 20 percent in the same prior year period. The increase in Internet revenues contributed to the Company's percentage of commissionable revenues decreasing from 33.0 percent in 1999 to 29.0 percent in 2000.

Aircraft rentals per ASM decreased 13.5 percent due to a lower percentage of the aircraft fleet being leased.

Landing fees and other rentals per ASM decreased 2.2 percent primarily as a result of a decrease in landing fees per ASM of 6.5 percent, partially offset by a slight increase in other rentals. Although landing fees declined on a per ASM basis, they were basically flat on a per trip basis. The growth in ASMs exceeded the trip growth primarily due to an increase in the average distance per aircraft trip flown.

Other expenses (income) include interest expense, capitalized interest, interest income, and other gains and losses. Interest expense increased approximately 31.8 percent due primarily to the Company's issuance of $256 million of long-term debt in fourth quarter 1999. Capitalized interest decreased 15.7 percent primarily as a result of lower 2000 progress payment balances for scheduled future aircraft deliveries compared to 1999 and lower interest rates. Interest income increased 79.6 percent primarily due to higher invested cash balances.

Comparison of Nine Months Ended September 30, 2000 to Nine Months Ended September 30, 1999

Consolidated net income before the cumulative effect of change in accounting principle for the nine months ended September 30, 2000 was $470.6 million ($.89 per share, diluted), an increase of 23.6 percent compared to 1999. The cumulative effect of change in accounting principle for 2000 was $22.1 million, net of taxes of $14.0 million (see Note 5 to the unaudited Condensed Consolidated Financial Statements). Net income, after the cumulative change in accounting principle, for 2000 was $448.4 million. Diluted net income per share, after consideration of the accounting change, was $.85 compared to $.71 in 1999. Operating income was $770.1 million, an increase of 22.7 percent compared to 1999.

Consolidated operating revenues increased 18.4 percent primarily due to a 19.0 percent increase in passenger revenues. The increase in passenger revenues primarily resulted from the Company's increased capacity, strong demand for commercial air travel, and excellent revenue management. The Company experienced an 11.0 percent increase in revenue passengers carried, a 15.7 percent increase in RPMs, and a 2.8 percent increase in passenger revenue yield per RPM (passenger yield). The increase in passenger yield is primarily due to a 7.1 percent increase in average passenger fare, partially offset by a 4.1 percent increase in average length of passenger haul.

The increase in RPMs exceeded a 13.5 percent increase in ASMs resulting in a load factor of 71.0 percent, or 1.4 points above the same prior year period. The increase in ASMs resulted primarily from the net addition of 28 aircraft since third quarter 1999, which represents a 9.2 percent increase in the Company's fleet size.

Consolidated freight revenues increased 9.8 percent primarily due to an increase in capacity. Other revenues decreased 1.8 percent primarily due to a decrease in commercial charter revenue. The Company had less aircraft devoted to its charter business compared to 1999 due to the strong demand for scheduled passenger service.

Operating expenses per ASM increased 3.6 percent to $.0772, compared to $.0745 for 1999, primarily due to a significant increase in average jet fuel prices. The average fuel cost per gallon was 63.3 percent higher than the same 1999 period. Excluding fuel expense, operating expenses per ASM decreased 3.2 percent.

Salaries, wages, and benefits per ASM were flat, as increases in productivity were offset by increases in average wage rates and in Employee benefit costs, primarily health care and workers' compensation expenses. Profitsharing and Employee savings plan expenses per ASM increased primarily due to the increase in Company earnings available for profitsharing.

Fuel and oil expense per ASM increased 56.5 percent due to a 63.3 percent increase in the average jet fuel cost per gallon compared to 1999. The average price paid for jet fuel in 2000 was $.7793 per gallon compared to $.4772 in 1999, including the effects of hedging activities. The Company's 2000 and 1999 average jet fuel prices are net of approximately $49.4 million and $10.2 million in gains from hedging activities, respectively. See comparison of third quarter 2000 to third quarter 1999 for a schedule of the Company's fuel hedging positions for the remainder of 2000 and for 2001.

Maintenance materials and repairs per ASM decreased 8.6 percent primarily because of a decrease in engine maintenance related to the Company's 737-200 aircraft fleet as 1999 was an unusually high period for engine maintenance on these aircraft. The engines on these aircraft are not covered by the Company's "power-by-the-hour" maintenance contract with General Electric Engine Services, Inc.; therefore, repairs are expensed on a time and materials basis. These engine repairs represented approximately 63 percent of the total decrease, while a decrease in airframe inspections and repairs per ASM represented approximately 34 percent of the total decrease.

Agency commissions per ASM decreased 10.0 percent, primarily due to an increase in direct sales. More than 29 percent of the Company's 2000 revenues were attributable to direct bookings through the Company's Internet site compared to approximately 17 percent in the same prior year period. The increase in Internet revenues contributed to the Company's percentage of commissionable revenues decreasing from 34.8 percent in 1999 to 29.7 percent in 2000.

Aircraft rentals per ASM decreased 13.2 percent due to a lower percentage of the aircraft fleet being leased.

Landing fees and other rentals per ASM decreased 4.3 percent primarily as a result of a decrease in landing fees per ASM of 6.7 percent, partially offset by a slight increase in other rentals. Although landing fees declined on a per ASM basis, they were basically flat on a per trip basis. The growth in ASMs exceeded the trip growth primarily due to an increase in the average distance per aircraft trip flown.

Depreciation expense per ASM increased 2.2 percent primarily due to a higher percentage of owned aircraft. Of the 35 aircraft added to the Company's fleet over the past twelve months, 34 have been purchased. This, combined with the retirement of 7 leased aircraft, has increased the Company's percentage of aircraft owned or on capital lease from 67 percent at September 30, 1999 to 72 percent at September 30, 2000.

Other operating expenses per ASM decreased 4.7 percent primarily due to Company-wide cost reduction efforts in areas such as supplies, advertising, optional training, communication costs, etc.

Other expenses (income) include interest expense, capitalized interest, interest income, and other gains and losses. Interest expense increased 30.5 percent due primarily to the Company's issuance of $256 million of long-term debt in fourth quarter 1999. Capitalized interest decreased 14.3 percent primarily as a result of lower 2000 progress payment balances for scheduled future aircraft deliveries compared to 1999 and lower interest rates. Interest income increased 52.7 percent primarily due to higher invested cash balances. Other losses in 1999 resulted primarily from a write-down associated with the consolidation of certain software development projects.

Liquidity and Capital Resources

Net cash provided by operating activities was $1,043.1 million for the nine months ended September 30, 2000 and $1,262.4 million for the 12 months then ended. Also, during fourth quarter 1999, additional funds of $256 million were generated through the issuance of floating rate long-term debt from two separate financing transactions. Cash generated for the 12 months ended September 30, 2000 was primarily used to finance aircraft-related capital expenditures, provide working capital, and to repurchase approximately $199.2 million of the Company's outstanding common stock. The Company began this repurchase program during third quarter 1999. Through September 30, 2000, the program resulted in the repurchase of approximately 12.2 million shares at an average cost of $16.28 per share.

During the 12 months ended September 30, 2000, net capital expenditures were $1,064.9 million, which primarily related to the purchase of 31 new 737-700 aircraft, one used 737-700 aircraft, two used 737-300 aircraft, and progress payments for future aircraft deliveries.

The Company's contractual commitments consist primarily of scheduled aircraft acquisitions. As of September 30, 2000, 10 737- 700s are scheduled for delivery in the remainder of 2000, 21 in 2001, 31 in 2002, 13 in 2003, 29 in 2004, and 52 during the period 2005 to 2007. In addition, the Company has options to purchase up to 87 737- 700s during 2003-2008 and purchase rights for up to 217 additional aircraft during 2007-2012. The Company has the option, which must be exercised two years prior to the contractual delivery date, to substitute 737-600s or 737-800s for the 737-700s scheduled subsequent to 2001. Aggregate funding needed for fixed commitments at September 30, 2000 was approximately $4,488 million due as follows: $266 million in 2000; $749 million in 2001; $912 million in 2002; $472 million in 2003; $641 million in 2004; and $1,448 million thereafter.

The Company has various options available to meet its capital and operating commitments, including cash on hand at September 30, 2000 of $580.6 million, internally generated funds, and a revolving credit line with a group of banks of up to $475 million (none of which had been drawn at September 30, 2000). In addition, the Company will also consider various borrowing or leasing options to maximize earnings and supplement cash requirements.

The Company currently has outstanding shelf registrations for the issuance of $318.8 million in public debt securities which it may utilize for aircraft financing and general corporate purposes during 2000 and 2001.

The Company began new service to Buffalo, New York, on October 8, 2000, with daily nonstop service to Baltimore/Washington, Las Vegas, Phoenix, and Orlando.

See Item 7A. Quantitative and Qualitative Disclosures About Market Risk in the Company's Annual Report on Form 10-K for the year ended December 31, 1999.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The Company received a notice of deficiency from the Internal Revenue Service (IRS) in which it proposed to defer deductions claimed by the Company on its federal income tax returns for the taxable years 1989 through 1991 for the costs of certain aircraft inspection and maintenance procedures. In defense of the notice of deficiency, the Company filed a petition in the United States Tax Court on October 30, 1997, seeking a determination that the IRS erred in disallowing the deductions claimed by the Company and that there is no deficiency in the Company's tax liability for the taxable years in issue. The notice of deficiency received by the Company stemmed from an industry-wide challenge by the IRS of the long standing practice of currently expensing aircraft inspection and maintenance costs, and similar adjustments have been proposed by the IRS to the tax returns of numerous other members of the airline industry. In response to this challenge, the Air Transport Association of America, the airline industry's trade association, since late 1996 has been in discussions with the Treasury Department and the national office of the IRS regarding the issuance of published guidance confirming the industry's practice of expensing the subject inspection and maintenance costs. Approximately one month ago, counsel for the Company and the IRS jointly advised the Tax Court that the IRS expects to publish guidance favorable to the airline industry by early November 2000. Following the publication of the guidance, counsel for the Company and the IRS will attempt to resolve the controversy without the necessity of further litigation. Management believes that the final resolution of this controversy will not have a materially adverse effect upon the financial position and results of operations of the Company.

2.2 The two hundred seventeen (217) Rollover Option Aircraft may be converted into Option Aircraft or firm Aircraft, from time to time, in any of the following ways:

2.2.1 Buyer can exercise any Option for an Option Aircraft described in Article 1 above, and will be offered the right to convert one Rollover Option Aircraft into an Option Aircraft for each Option exercised.

2.2.2 If Buyer elects not to exercise an Option, Buyer may convert one Rollover Option Aircraft to an Option Aircraft; otherwise, one Rollover Option Aircraft will be deleted for each Option not exercised by Buyer.

2.2.3 Buyer may convert Rollover Option Aircraft directly to firm Aircraft. When Buyer converts one or more Rollover Option Aircraft to firm Aircraft, Buyer will be offered the right to convert one Rollover Option Aircraft into an Option Aircraft for each converted Rollover Option Aircraft.

2.3 Buyer may not convert Rollover Option Aircraft to Option Aircraft except in accordance with Article 2.2 above.

2.4 Base Price Adjustments for Rollover Option Aircraft which are converted to Option Aircraft or firm Aircraft shall be in accordance with Article 2.2.5 of Attachment A to this Letter Agreement.

2.5 The delivery month offered by Boeing to Buyer for any Option or firm Aircraft resulting from a conversion of a Rollover Option Aircraft will be at least 24 months from the corresponding Option exercise date or firm order.

2.6 Upon conversion of a Rollover Option Aircraft into an Option Aircraft, Buyer shall wire transfer the Deposit of *** to Boeing and Boeing and Buyer shall agree on a delivery position for that aircraft. Section 1 of this Letter Agreement will be amended accordingly. In the event Buyer thereafter exercises its right to purchase such Option Aircraft, application of the Deposit will be in accordance with Article 4.1 herein. If the conversion is a Rollover Option Aircraft to a firm Aircraft, Buyer shall wire transfer any advance payments due under the Agreement.

2.7 Buyer and Boeing will consult on a frequent basis to keep each other informed as to Buyer's fleet plans and Boeing's production plans in order to accommodate to the greatest extent reasonably possible each party's needs in managing the delivery schedule for the Rollover Option Aircraft. Boeing acknowledges Buyer's need for delivery positions in the 2007-2012 time frame, as well as the possibility of a need for delivery positions in earlier years and will use its best reasonable efforts to meet Buyer's needs.

3.4 The Option Aircraft purchase price will be the applicable basic price thereof at the time of Option Aircraft delivery adjusted in accordance with Boeing's Aircraft escalation provisions contained in the definitive agreement to purchase the Option Aircraft. The purchase price will include the price for Seller Purchased Equipment (SPE) if Buyer has elected to change Buyer Furnished Equipment (BFE) to SPE.

4. Option Aircraft Payment.

4.1 In consideration of the granting of the Options as set forth herein, on or before the date Boeing and Buyer enter into a definitive agreement to purchase the Aircraft, Buyer will pay a deposit to Boeing of *** for each Option Aircraft (Deposit). In the event Buyer exercises its Options herein, the amount of the Deposit will be credited against the first advance payment due for such Option Aircraft pursuant to the advance payment schedule set forth in paragraph 3 of Attachment A. The Deposits for the Option Aircraft will be refunded to Buyer, without interest, if the parties do not enter into a definitive Agreement for the Aircraft.

In the event that, after the parties enter into a definitive agreement to purchase the Aircraft, Buyer does not exercise its Options to purchase the Option Aircraft pursuant to the terms and conditions set forth herein, Boeing will be entitled to retain the Deposits for the Option Aircraft except as provided in paragraph 6 herein.

4.2 Advance payments in the amount of 30% of the advance payment base price will be payable on the Option Aircraft in accordance with paragraph 3 of Attachment A. The remainder of the Option Aircraft purchase price is due at the time of delivery of the Option Aircraft.

5. Option Exercise.

5.1 To exercise its Option, Buyer will give written or telegraphic notice thereof to Boeing on or before *** months prior to the first day of the delivery month of each Option Aircraft.

In such notice Buyer will select the Option Model type, and the applicable delivery positions.

5.2 It is understood and agreed that Boeing may accelerate the Option exercise dates specified above if Boeing must make production decisions which are dependent on Buyer's decision to buy the Option Aircraft. If Boeing elects to accelerate the Option exercise dates, Boeing will do so by giving written or telegraphic notice thereof to Buyer. Such notice will specify the revised Option exercise dates, which will not be earlier than 30 days after the date of transmittal of such notice, and the Option Aircraft delivery positions affected by such revision. If Buyer fails to exercise its Option for any Option Aircraft affected by such revised dates, the Deposit applicable to such Option Aircraft will be promptly refunded, ***

6. Contract Terms.

It is understood that Boeing and Buyer will use their best efforts to enter into a definitive agreement for the Option Aircraft within thirty (30) days after Buyer exercises an Option to purchase Option Aircraft pursuant to paragraph 5 covering the detailed terms and conditions for the sale of such Option Aircraft.

Such definitive agreement will include the terms and conditions contained herein together with the terms and conditions, not inconsistent herewith, contained in Boeing's then-current standard form of purchase agreement for the sale of Model 737-700 aircraft in effect as of the date of Option exercise and such additional terms and conditions as may be mutually agreed upon. In the event the parties have not entered into such an agreement within the time period contemplated herein, either party may, exercisable by written or telegraphic notice given to the other within thirty (30) days after such period, terminate the purchase of such Option Aircraft.

7. Termination of Option to Purchase.

Either Boeing or Buyer may terminate the Options to purchase an Option Aircraft if any of the following events are not accomplished by the respective dates contemplated in this letter agreement, or in the Agreement, as the case may be:

(i) termination of the purchase of the Aircraft under the Agreement for any reason;

(ii) payment by Buyer of the Deposit with respect to an Option Aircraft pursuant to paragraph 4.1 herein;

(iii) exercise of an Option to purchase an Option Aircraft pursuant to the terms hereof.

Any termination of an Option to purchase by Boeing which is based on the termination of the purchase of Aircraft under the Agreement will be on a one-for-one basis, for each Aircraft so terminated.

Any cancellation of an Option to purchase which is based on failure to make the required Deposit or to exercise the Option to purchase shall only apply to the Option Aircraft so canceled.

Termination of an Option to purchase provided by this letter agreement will be caused by either party giving written notice to the other within 10 days after the applicable date. Upon receipt of such notice, all rights and obligations of the parties with respect to an Option Aircraft for which the Option to purchase has been terminate will thereupon terminate.

If termination is result of a revision of an Option exercise date by Boeing pursuant to paragraph 5.2, Boeing will promptly refund to Buyer, with interest, any payments received from Buyer, including the Deposit, with respect to the Option Aircraft for which the Option is terminated. If termination is for any other reason, Boeing will promptly refund to Buyer, without interest, any payments received from Buyer with respect to the affected Option Aircraft, except the Deposit, which Buyer may apply to any model Boeing aircraft purchased by Buyer from Boeing at a future date.

8. Confidential Treatment. Buyer understands that certain commercial and financial information contained in this Letter Agreement including any attachments hereto is considered by Boeing as confidential. Buyer 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 except as provided in Letter Agreement No. 6-1162-RLL-934, as amended.

PRICE ADJUSTMENT DUE TO
ECONOMIC FLUCTUATIONS
AIRCRAFT PRICE ADJUSTMENT
(July 1999 Base Price)

1. Formula.

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

Pa = (P+B)(L + M) - P

Where:

Pa = Aircraft Basic Price Adjustment. (For Model 717-200, 737-600, 737-700, 737-800 and 737-900, the Aircraft Basic Price includes the Engine Price at its basic thrust level.)

L =     .65 x  ECI / ECIb
                                        where ECIb is the base year
                                        index (as set forth in Table
                                        1 of the applicable purchase
                                        agreement)

M =     .35 x  ICI / ICIb
                                        where ICIb is the base year
                                        index (as set forth in Table
                                        1 of the applicable purchase
                                        agreement)

P = Base Aircraft Price plus Optional Features Price (as set forth in the applicable purchase agreement).

B =     0.005 x (N/12) x (P)            where N is the calendar month
                                        and year of scheduled Aircraft
                                        delivery minus the calendar
                                        month and year of the Base Price
                                        Year, both as shown in Table 1
                                        of the applicable purchase
                                        agreement.

ECI is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics "Employment Cost Index for workers in aerospace manufacturing - Wages and Salaries" (ECI code 3721W), calculated by establishing a three-month arithmetic average value (expressed as a decimal and rounded to the nearest tenth) using the values for the fifth, sixth and seventh 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.

ICI is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics "Producer Prices and Price Index - Industrial Commodities Index ", 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 5th, 6th and 7th 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 January, the months June, July and August of the preceding year will be utilized in determining the value of ECI and ICI.

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 Aircraft Basic Price Adjustment formula.

iii. .35 is the numeric ratio attributed to materials in the Aircraft Basic 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 (base year June 1989 = 100). The applicable base year and corresponding denominator will be provided by Boeing in the applicable purchase agreement.

v. If the calculated sum of L + M is less than 1.0000, then the value of the sum is adjusted to 1.0000.

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 ICI 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 Aircraft Basic 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 Aircraft Basic adjustment, such values will be used to determine any increase or decrease in the Aircraft Basic Price Adjustment for the aircraft from that determined at the time of delivery of the aircraft.

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 ICI values as defined above, such re-based values will be incorporated in the Aircraft Basic 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 Purchase Price of any affected aircraft to reflect an allowance for increases or decreases in labor compensation and material costs occurring since February of the price base year shown in the applicable purchase agreement which is consistent with the applicable provisions of paragraph 1 of this Supplemental Exhibit D-1.

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 Aircraft Basic 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 Memo or Supplemental Invoice will be issued for the Aircraft Basic Price Adjustment difference. Interest charges will not apply for the period of original invoice to issuance of Credit Memo or Supplemental Invoice.

Note: i. The values released by the Bureau of Labor Statistics and available to Boeing 30 days prior to the scheduled delivery month of an aircraft will be used to determine the ECI and ICI values for the applicable months (including those noted as preliminary by the Bureau of Labor Statistics) to calculate the Aircraft Basic Price Adjustment for the aircraft invoice at the time of delivery. The values will be considered final and no Aircraft 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 Aircraft Basic 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.

3.4.2 Adjustment of Advance Payment Base Prices - Long-Lead Aircraft. For Aircraft scheduled for delivery 36 months or more after the date of this Agreement, the Advance Payment Base Prices appearing in Article 3.4.1 will be used to determine the amount of the first advance payment to be made by Buyer on the Aircraft. No later than 25 months before the scheduled month of delivery of each affected Aircraft, Boeing will increase or decrease the Advance Payment Base Price of such Aircraft as required to reflect the effects of (i) any adjustments in the Aircraft Basic Price pursuant to this Agreement and (ii) the then-current forecasted escalation factors used by Boeing. Boeing will provide the adjusted Advance Payment Base Prices for each affected Aircraft to Buyer, and the advance payment schedule will be considered amended to substitute such adjusted Advance Payment Base Prices.
