6. Accounting changes - Effective January 1, 2001, the Company adopted Statement of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended (SFAS 133). SFAS 133 requires the Company to record all financial derivative instruments on its balance sheet at fair value. Derivatives that are not designated as 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 that are considered to be effective, as defined, either offset the change in fair value of the hedged assets, liabilities, or firm commitments through earnings or are recorded in accumulated other comprehensive income until the hedged item is recorded in earnings. Any portion of a change in a derivative's fair value that is considered to be ineffective, as defined, is recorded immediately in Other
(gains) losses, net in the Condensed Consolidated Statement of Income. Any portion of a change in a derivative's fair value that the Company elects to exclude from its measurement of effectiveness is required to be recorded immediately in earnings.

Airline operators are inherently dependent upon energy to operate and, therefore, are impacted by changes in jet fuel prices. The Company endeavors to acquire jet fuel at the lowest prevailing prices possible. Because jet fuel is not traded on an organized futures exchange, liquidity for hedging is limited. However, the Company has found that both crude oil and heating oil contracts are effective commodities for hedging jet fuel. The Company has financial derivative instruments in the form of the types of hedges it utilizes to decrease its exposure to jet fuel price increases. The Company does not purchase or hold any derivative financial instruments for trading purposes.

The Company utilizes financial derivative instruments for both short-term and long-term time frames when it appears the Company can take advantage of market conditions. At September 30, 2001, the Company had a mixture of purchased call options, collar structures, and fixed price swap agreements in place to hedge approximately 80 percent of its remaining 2001 total anticipated jet fuel requirements, approximately 50 percent of its 2002 total anticipated jet fuel requirements, and small portions of its 2003-2005 total anticipated jet fuel requirements. As of September 30, 2001, nearly all of the Company's remaining 2001 hedges, and the majority of its 2002 hedges, are effectively heating oil-based positions. All other remaining hedge positions are crude oil-based.

The Company accounts for its fuel hedge derivative instruments as cash flow hedges, as defined. Upon adoption of SFAS 133, the Company recorded the fair value of its fuel derivative instruments in the Condensed Consolidated Balance Sheet and a deferred gain of $46.1 million, net of tax, in accumulated other comprehensive income. The portion of the transition adjustment in "Accumulated other comprehensive income" that was recognized in earnings during third quarter 2001 was a gain of $9.2 million, net of tax. During third quarter 2001, the Company recognized approximately $4.4 million as a net expense in Other (gains) losses, net, related to the ineffectiveness of its hedges, in the Condensed Consolidated Statement of Income. During third quarter 2001, the Company recognized approximately $504,000 of net expense, related to amounts excluded from the Company's measurements of hedge effectiveness, in Other (gains) losses, net in the Condensed Consolidated Statement of Income. The current year adoption of SFAS 133 has resulted in more volatility in the Company's financial statements than in the past.

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 resulting from the flight segment credits sold are earned and flown or credits expire unused. Due to this change, the Company recorded a cumulative effect charge in first quarter 2000 of $22.1 million (net of income taxes of $14.0 million) or $.03 per share, basic and diluted.

7. Comprehensive income - Comprehensive income includes changes in the fair value of certain financial derivative instruments, which qualify for hedge accounting, and unrealized gains and losses on certain investments. For the three and nine months ended September 30, 2001, comprehensive income totaled $120.4 million and $449.0 million, respectively. The difference between net income and comprehensive income for the three and nine months ended September 30, 2001 is as follows (in thousands):

As of September 30, 2001, the Company had approximately $2.6 million in unrealized gains, net of tax, in accumulated other comprehensive income related to fuel hedges. Included in this total are approximately $5.7 million in net unrealized gains that are expected to be realized in earnings over the twelve months following September 30, 2001. Upon the adoption of SFAS 133 on January 1, 2001, the Company recorded unrealized fuel hedge gains of $46.1 million, net of tax, of which approximately $45.1 million were expected to be realized in earnings over the twelve months following January 1, 2001.

8. September 11, 2001 Terrorist Attacks - On September 11, 2001, terrorists hijacked and used two American Airlines, Inc. aircraft and two United Air Lines, Inc. aircraft in terrorist attacks on the United States (terrorist attacks). As a result of these terrorist attacks, the Federal Aviation Administration (FAA) immediately suspended all commercial airline flights on the morning of September 11. The Company resumed flight activity on September 14 and was operating its normal pre-September 11 flight schedule by September 18, 2001. From September 11 until the Company resumed flight operations on September 14, Southwest cancelled approximately 9,000 flights. Although flight operations were suspended, the Company continued to incur nearly all of its normal operating expenses (with the exception of certain direct trip-related expenditures such as fuel, landing fees, etc.). Once the Company resumed operations, load factors and yields were severely impacted, along with increased ticket refund activity.

8

The Company incurred total operating losses of approximately $25 million during the time our operations were suspended. As a result of reduced load factors and yields after the terrorist attacks once operations were resumed, the Company continued to incur operating losses through the end of third quarter 2001 of approximately $95 million. Although load factors have returned to somewhat normal levels by the end of October 2001, yields have continued to be significantly below prior year levels. The Company expects this trend to continue for the forseeable future due primarily to aggressive fare discounting within the industry.

On September 22, 2001, President Bush signed into law the Air Transportation Safety and System Stabilization Act (Act). The Act provides for up to $5 billion in cash grants to qualifying U.S. airlines and freight carriers to compensate for direct and incremental losses, as defined in the Act, associated with the terrorist attacks. The Act also provides for other items such as protection against certain insurance coverage increases, delaying payments of excise taxes, and certain protections against lawsuits for the airlines directly involved in the attacks.

In response to the decrease in demand for air travel since the terrorist attacks, the Company has also modified its schedule for future aircraft deliveries and the timing of its future capital expenditure commitments. See Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources for further discussion of the Company's long-term commitments for aircraft.

In accordance with generally accepted accounting principles, consolidated net income for third quarter 2001 included approximately $169.0 million in "Other gains" that the Company recognized from grants under the Act and special pre-tax charges of approximately $58.0 million arising from the terrorist attacks. The $169.0 million gain recognized in third quarter 2001 was the Company's estimate of its direct and incremental losses, as defined in the Act, incurred in third quarter 2001 as a result of the terrorist attacks. Special charges arising from the terrorist attacks resulted from or include refunds of nonrefundable fares, provisions for uncollectible accounts, write-downs of various assets due to impairment, and estimated charges for the deferral of Boeing 737 aircraft firm orders and options

9. Credit facility - In September 2001, the Company borrowed the full $475 million available under its unsecured revolving credit line with a group of banks. Borrowings under the credit line bear interest at six-month LIBOR plus 15.5 basis points and amounts are repayable on or before May 6, 2002. The Company intends to repay the borrowings in full prior to the due date with either cash on hand or proceeds from issuance of long-term debt securities. The full $475 million is classified as Current maturities of long-term debt in the Condensed Consolidated Balance Sheet.

10. Recently issued accounting standards - On August 16, 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards SFAS No. 143, "Accounting for Asset Retirement Obligations", which is effective for financial statements issued for fiscal years beginning after June 15, 2002. The pronouncement addresses the recognition and re-measurement of obligations associated with the retirement of tangible long-lived assets. On October 3, 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets", which is effective for financial statements issued for fiscal years beginning after December 15, 2001. SFAS 144 supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of", and applies to all long-lived assets (including discontinued operations). The Company is currently reviewing these statements but does not expect them to have a material impact on future financial statements or results of operations.

9

11. Subsequent events - On October 30, 2001, the Company issued $614.3 million Pass Through Certificates consisting of $150.0 million 5.1% Class A-1 certificates, $375.0 million 5.5% Class A-2 certificates, and $89.3 million 6.1% Class B certificates. A separate trust was established for each class of certificates. The trusts used the proceeds from the sale of certificates to acquire equipment notes, which were issued by Southwest on a full recourse basis. Payments on the equipment notes held in each trust will be passed through to the holders of certificates of such trust. The equipment notes were issued for each of 29 Boeing 737-700 aircraft owned by Southwest and are secured by the mortgage on such aircraft. Interest on the equipment notes held for the certificates is payable semiannually, beginning May 1, 2002. Principal payments on the equipment notes held for the Class A-1 certificates are due semiannually beginning May 1, 2002. The entire principal of the equipment notes for the Class A-2 and Class B certificates are scheduled for payment on November 1, 2006. Southwest will use the proceeds from the issuance of the equipment notes for general corporate purposes, including, among other possible uses, repayment of the $475 million of borrowings outstanding under Southwest's bank credit facility and accrued interest thereon.

MATERIAL CHANGES IN RESULTS OF OPERATIONS

COMPARISON OF THREE MONTHS ENDED SEPTEMBER 30, 2001 TO THREE MONTHS

ENDED SEPTEMBER 30, 2000

Consolidated net income for third quarter 2001 was $151.0 million ($.19 per share, diluted), as compared to third quarter 2000 net income of $184.3 million ($.23 per share, diluted), a decrease of 18.1 percent. The prior year's net income per share amounts have been restated for the 2001 three-for-two stock split (see Note 3 to the unaudited Condensed Consolidated Financial Statements). Operating income was $93.0 million, a decrease of 69.0 percent compared to 2000. In accordance with generally accepted accounting principles, consolidated net income for third quarter 2001 included approximately $169.0 million in "Other gains" that the Company recognized from grants under the Act and special pre-tax charges of approximately $58.0 million arising from the terrorist attacks. See Note 8 to the unaudited Condensed Consolidated Financial Statements. Excluding the gain and special charges, third quarter 2001 net income was $82.8 million, or $.10 per share, diluted.

Consolidated operating revenues decreased 9.7 percent due primarily to a 9.6 percent decrease in passenger revenues. The decrease in passenger revenues was a direct result of the September 11, 2001 terrorist attacks. The Company's combined July and August passenger revenues were approximately 4.5 percent higher than the same period in 2000. However, September 2001 passenger revenues were 41.3 percent lower than September 2000, including an adjustment to decrease revenues further as a result of refunds of nonrefundable fares previously estimated to expire. The adjustment was necessary as a result of the Company's relaxation of its normal refund policy rules following the terrorist attacks. Third quarter 2001 capacity, as measured by ASMs, increased 6.4 percent. The increase in ASMs resulted primarily from the addition of 24 aircraft since third quarter 2000, which represents a 7.2 percent increase in the Company's fleet size. The increase in fleet size was partially offset by the Company's cancellation of approximately 9,000 flights from September 11 through September 17, as a result of the terrorist attacks. The third quarter 2001 load factor was 69.1 percent, a decrease of 2.5 points compared to 2000. The Company experienced a 1.8 percent decrease in revenue passengers carried, a 2.7 percent increase in RPMs, and a 12.0 percent decrease in passenger revenue yield per RPM (passenger yield). For the period July 1, 2001 until the terrorist attacks, Southwest's load factor was 74.6 percent, or 1.1 points above the year ago period. The Company's passenger revenue per available seat mile (RASM) was $.0870, or 7.1 percent below the year ago period. After the September 11 attacks and resuming service on September 14, Southwest's load factor was 45.4 percent through September 30, or 19.4 points below the year ago period. The Company's RASM for this same period was $.0484, or 44.5 percent below the year ago period.

The Company's load factor for October 2001 was 63.7 percent, down 6.3 points compared to the October 2000 load factor of 70.0 percent. The load factor for the two-week period ended November 11, 2001 was 60.5 percent, down 6.7 points compared to the same period in 2000. Likewise, RASM for the two-week period ended November 11, 2001 was an estimated $.0669, compared to $.0879 during the comparable prior year period. Passenger yield for this same two-week period was an estimated $.1105 in 2001 compared to $.1307 in 2000. Weak air travel conditions have spawned aggressive fare sales and the Company expects yields per RPM to be well below year ago levels for the foreseeable future. Without consideration of the federal grants the Company expects to recognize in fourth quarter 2001, the Company is unable to predict whether or not it will be profitable for fourth quarter 2001. However, barring any unforeseen events, we expect to be profitable for full year 2001. (The immediately preceding two sentences are forward-looking statements that involve uncertainties that could result in actual results differing materially from expected results. Some significant factors include, but may not be limited to, additional incidents that could cause the public to question the safety and/or efficiency of air travel, competitive pressure such as fare sales and capacity changes by other carriers, general economic conditions, and variations in advance booking trends.)

12

As a result of the terrorist attacks and weak economic conditions throughout third quarter 2001, consolidated freight revenues decreased 25.5 percent. Combined July and August freight revenues were approximately 13.0 percent lower than the same period in 2000. However, September 2001 freight revenues were 49.5 percent lower than September 2000. Subsequent to the resumption of service after the terrorist attacks, the U.S. Postal Service made a decision to divert more of its mail shipments to freight carriers from commercial airlines. Additionally, the FAA instituted significantly heightened security rules for commercial airlines carrying freight following the terrorist attacks. As a result of these recent developments, the Company expects year-over-year declines in freight revenues to continue throughout the near term. (The immediately preceding sentence is a forward-looking statement that involves uncertainties that could result in actual results differing materially from expected results. Some significant factors include, but may not be limited to, decisions by major freight customers on how they allocate freight deliveries among different types of carriers, general economic conditions, etc.) Other revenues increased 3.2 percent due primarily to an increase in commissions earned from programs the Company sponsors with certain business partners, such as the Company sponsored First USA Visa card. That increase was partially offset by a decline in charter revenues as a result of the terrorist attacks.

Operating expenses per ASM were $.0762, a 1.0 percent decrease compared to $.0770 for 2000. Excluding fuel expense, operating expenses per ASM increased .2 percent to $.0644. Due to the Company's approximately 9,000 flight cancellations as a result of the terrorist attacks, several of the operating expense captions in the Condensed Consolidated Statements of Income that are measured as a percentage of ASMs were impacted. However, the captions that typically fluctuate with actual flight activity, such as fuel and landing fees, were not materially affected on a per ASM basis.

As a result of the terrorist attacks, the Company put into effect a number of measures to control costs. The Company has deferred nonessential capital spending, cut nonessential operating expenses, and has temporarily suspended its fleet growth plans. Excluding fuel, it is difficult to accurately predict fourth quarter 2001 unit costs, especially with respect to potential increases in airport, security, and insurance costs. Were it not for these cost risks, the Company would project an overall decline in fourth quarter 2001 unit costs. (The immediately preceding sentence is a forward-looking statement which involves uncertainties that could result in actual results differing materially from expected results. Some significant factors include, but may not be limited to, wage and productivity pressures, new or additional security regulations, capacity decisions made by competitors, and general economic conditions.)

Salaries, wages, and benefits per ASM increased 7.9 percent. The increase was due primarily to the approximately 9,000 trips the Company was forced to cancel as a result of the September 11, 2001 terrorist attacks. All salaries, wages, and benefits normally incurred by the Company were paid during the time operations were suspended, but there were no corresponding ASMs.

Employee retirement plans expense per ASM decreased 40.0 percent, due primarily to the decrease in Company earnings available for profitsharing.

Fuel and oil expense per ASM decreased 7.1 percent due to a 5.8 percent decrease in the average jet fuel cost per gallon compared to 2000. The average jet fuel cost per gallon in third quarter 2001 was $.6984 compared to $.7412 in third quarter 2000, including the effects of hedging activities. The Company's third quarter 2001 average jet fuel cost is net of approximately $23.5 million in "effective" hedging gains, as defined. See Note 6 to the Condensed Consolidated Financial Statements. The Company's third quarter 2000

13

average jet fuel cost is net of approximately $43.1 million in gains from hedging activities. As of September 30, 2001, the Company had hedges in place for approximately 80 percent of its anticipated jet fuel requirements for the remainder of 2001. Including estimated hedging gains and considering current market prices and the continued effectiveness of the Company's fuel hedges, we are forecasting our fourth quarter 2001 average fuel price per gallon to be below third quarter 2001's average fuel cost per gallon of $.6984. The majority of the Company's near term hedge positions are in the form of option contracts, which should enable the Company to benefit to a large extent from a decline in jet fuel prices. However, the Company's overall fuel hedging strategy could result in the Company not fully benefiting from certain jet fuel price declines. (The immediately preceding three 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, the continued effectiveness of the Company's fuel hedges, and changes in the Company's overall fuel hedging strategy.)

Maintenance materials and repairs per ASM decreased 3.1 percent due to a decrease in engine repair expense per ASM. This decrease was due primarily to the Company's capacity growth exceeding the increase in expense. Virtually all the Company's third quarter capacity growth versus the prior year was accomplished with new aircraft, most of which have not yet begun to incur any meaningful engine repair costs. The Company expects fourth quarter 2001 maintenance materials and repairs per ASM to be in line with third quarter 2001 expense. (The immediately preceding sentence is a forward-looking statement involving uncertainties that could result in actual results differing materially from expected results. Such uncertainties include, but may not be limited to, any unscheduled required aircraft airframe or engine repairs and regulatory requirements.)

Agency commissions per ASM decreased 48.1 percent. Approximately 80 percent of the decrease was due to a change in the Company's commission rate policy and mix of commissionable revenues, and approximately 20 percent of the decrease was associated with the overall decline in revenues. Effective January 1, 2001, the Company reduced the commission rate paid to travel agents from ten percent to eight percent for Ticketless bookings, and from ten percent to five percent for paper ticket bookings. The percentage of commissionable revenues decreased from approximately 29 percent in third quarter 2000 to approximately 23 percent in third quarter 2001. The Company recently announced that effective October 15, 2001, we are reducing the commission paid to travel agents to five percent (with no cap), regardless of the type of ticket sold. Due to these commission policy changes in 2001, we expect agency commissions to show further year-over-year decreases in fourth quarter 2001 on a per-ASM basis. (The immediately preceding sentence is a forward-looking statement involving uncertainties that could result in actual results differing materially from expected results. Such uncertainties include, but may not be limited to, changes in consumer ticket purchasing habits.)

Aircraft rentals per ASM decreased 6.3 percent compared to third quarter 2000 due to a lower percentage of the aircraft fleet being leased. Approximately 26.3 percent of the Company's aircraft fleet was under operating lease at September 30, 2001, compared to 28.1 percent at September 30, 2000.

Landing fees and other rentals per ASM increased 8.9 percent primarily as a result of the Company's expansion of facilities in several airports. This increase was partially offset by a decrease in landing fees expense per ASM from credits the Company received from airports in third quarter 2001

from audits of prior periods. As a result of the September 11 terrorist attacks, most major airlines have reduced their flight schedules and/or have retired aircraft early due to the decrease in demand for air travel. Since Southwest has not reduced the number of flights it offers, the Company expects that the airport costs it shares with other airlines on the basis of flights offered or passengers carried, such as landing fees, will increase on a per ASM basis in future periods, including fourth quarter 2001. (The immediately preceding sentence is a forward-looking statement involving uncertainties that could result in actual results differing materially from expected results. Such uncertainties include, but may not be limited to, changes in competitors flight schedules, demand for air travel, etc.)

Depreciation expense per ASM increased 6.4 percent due primarily to a higher percentage of owned aircraft. All of the 24 aircraft added to the Company's fleet over the past twelve months have been purchased. This has increased the Company's percentage of aircraft owned or on capital lease from 71.9 percent at September 30, 2000 to 73.7 percent at September 30, 2001.

Other operating expenses per ASM increased 7.0 percent. The increase was due primarily to charges incurred to write down the value of certain assets the Company determined had been impaired due to depressed market values for aircraft and related parts and equipment as a result of the terrorist attacks and their impact on the airline industry. Excluding these charges, Other operating expense per ASM would have increased slightly due to the ASMs lost when operations were temporarily suspended as a result of the terrorist attacks.

Interest expense decreased 18.3 percent due primarily to the July 2001 redemption of $100 million notes. However, the Company expects fourth quarter 2001 interest expense to increase compared to third quarter 2001 expense as a result of recent financing transactions as discussed in Note 9 and Note 11 to the unaudited Condensed Consolidated Financial Statements. (The immediately preceding sentence is a forward-looking statement involving uncertainties that could result in actual results differing materially from expected results. Such uncertainties include, but may not be limited to, subsequent financing decisions made by the Company.) Capitalized interest decreased 13.7 percent due primarily to a reduction in progress payment balances for future aircraft deliveries. Interest income decreased 11.7 percent as higher invested cash balances were more than offset by a decrease in rates earned on investments. Other gains in third quarter 2001 resulted primarily from $169.0 million recognized as the Company's share of government grant funds from the Act related to third quarter 2001. The Company received the majority of these funds in third quarter 2001 and expects to receive the remaining portion of its share in fourth quarter 2001. If direct and incremental losses, as defined in the Act, continue, as expected currently, Southwest will recognize gains from additional grants of up to approximately $120 million during fourth quarter 2001. (The immediately preceding two sentences are forward-looking statements involving uncertainties that could result in actual results differing materially from expected results. Such uncertainties include, but may not be limited to, subsequent modifications or amendments to the Act, changes in the government's expected schedule of distributing grant funds, the Company's operating performance improving to the point where it would not qualify to receive its full estimated remaining share of grant funds, etc.)

COMPARISON OF NINE MONTHS ENDED SEPTEMBER 30, 2001 TO NINE MONTHS ENDED

SEPTEMBER 30, 2000

Consolidated net income for the nine months ended September 30, 2001 was $447.6 million ($.55 per share, diluted), as compared to 2000 net income, before the cumulative effect of change in accounting principle, of $470.6 million ($.60 per share, diluted), a decrease of 4.9 percent. The prior year's net income per share amounts have been restated for the 2001 three-for-two stock split (see Note 3 to the unaudited Condensed Consolidated Financial Statements). Excluding the grant and special charges related to the terrorist attacks, net income for the nine months ended September 30, 2001, was $379.5 million ($.47 per share, diluted). The cumulative effect of change in accounting principle for the nine months ended September 30, 2000 was $22.1 million, net of taxes of $14.0 million (see Note 6 to the unaudited Condensed Consolidated Financial Statements). Net income and diluted net income per share, after the cumulative change in accounting principle, for the nine months ended September 30, 2000 were $448.4 million and $.57, respectively. Operating income for the nine months ended September 30, 2001 was $594.0 million, a decrease of 22.9 percent compared to 2000.

Consolidated operating revenues increased 3.2 percent due primarily to a 3.3 percent increase in passenger revenues. The increase in passenger revenues primarily resulted from the Company's increased capacity, but was partially offset by a decrease of 3.8 percent in passenger yield due to aggressive fare discounting by the Company and airline industry in general. The Company experienced a 4.3 percent increase in revenue passengers carried, a 7.4 percent increase in RPMs, and a 9.9 percent increase in ASMs. The Company's load factor for the nine months ended September 30, 2001, was 69.4 percent, or 1.6 points below the same prior year period. The increase in ASMs resulted primarily from the net addition of 24 aircraft since third quarter 2000, which represents a 7.2 percent increase in the Company's fleet size.

As a result of weak economic conditions throughout 2001, consolidated freight revenues decreased 13.9 percent. There were decreases in both the number of freight shipments and revenue per shipment. Other revenues increased 25.0 percent due primarily to an increase in commissions earned from programs the Company sponsors with certain business partners, such as the Company sponsored First USA Visa card.

Operating expenses per ASM were $.0766, compared to $.0772 for 2000. Excluding fuel expense, operating expenses per ASM increased .3 percent to $.0641.

Salaries, wages, and benefits per ASM increased 4.6 percent. Approximately 52 percent of the increase in salaries and wages primarily was from increases in headcount and wage rates, while approximately 48 percent of the increase was due to an escalation in health benefits costs.

Employee retirement plans expense per ASM decreased 19.5 percent, due primarily to the decrease in Company earnings available for profitsharing.

Fuel and oil expense per ASM decreased 5.3 percent due to a 4.5 percent decrease in the average jet fuel cost per gallon compared to 2000. The average jet fuel cost per gallon for the nine months ended September 30, 2001 was $.7440 compared to $.7793 in 2000, including the effects of hedging activities. The Company's 2001 average jet fuel cost is net of approximately $68.4 million in "effective" hedging gains, as defined. See Note 6 to the unaudited Condensed Consolidated Financial Statements. The Company's 2000 average jet fuel cost is net of approximately $49.4 million in gains from hedging activities.

16

Maintenance materials and repairs per ASM decreased 1.6 percent. A decrease in engine repair expense per ASM was partially offset by an increase in airframe inspection and repairs expense per ASM. The decrease in engine repair expense per ASM was due primarily to the Company's capacity growth exceeding the increase in expense. Virtually all the Company's 2001 capacity growth was accomplished with new aircraft, most of which have not yet begun to incur any meaningful engine repair costs. The increase in airframe inspection and repairs was primarily a result of more of these repairs being outsourced than in the prior year due to a larger amount of this type of work than the Company could perform with internal headcount and facilities.

Agency commissions per ASM decreased 37.0 percent due primarily to a change in the Company's commission rate policy effective January 1, 2001. The Company reduced the commission rate paid to travel agents from ten percent to eight percent for Ticketless bookings, and from ten percent to five percent for paper ticket bookings. The percentage of commissionable revenues decreased from approximately 29 percent in 2000 to approximately 25 percent in 2001.

Aircraft rentals per ASM decreased 9.1 percent due to a lower percentage of the aircraft fleet being leased.

Landing fees and other rentals per ASM increased 2.2 percent primarily as a result of an increase in other rentals partially offset by a decrease in landing fees. The increase in other rentals is due primarily to the Company's expansion of facilities in several airports.

Depreciation expense per ASM increased 4.3 percent due primarily to a higher percentage of the aircraft fleet being owned.

Other operating expenses per ASM increased 6.3 percent primarily from small increases in several areas that had previously been postponed as part of a prior year cost reduction effort.

Interest expense decreased 8.4 percent due primarily to the July 2001 redemption of $100 million notes. Capitalized interest decreased 14.5 percent due primarily to a reduction in progress payment balances for future aircraft deliveries. Interest income increased 2.1 percent as an increase in invested cash balances was partially offset by a decrease in rates earned on investments. Other gains in 2001 resulted primarily from the Company's share of government grant funds from the Act that were determined to be related to direct and incremental losses incurred in third quarter 2001 as a result of the terrorist attacks.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities was $1.25 billion for the nine months ended September 30, 2001 and $1.505 billion for the 12 months then ended. In addition, the Company accessed its $475 million bank credit facility in September 2001 following the terrorist attacks. See Note 9 to the unaudited Condensed Consolidated Financial Statements. Cash generated for the 12 months ended September 30, 2001 was primarily used to finance aircraft-related capital expenditures and provide working capital. See Note 11 to the Condensed Consolidated Financial Statements for subsequent events involving liquidity in fourth quarter 2001.

17

During the 12 months ended September 30, 2001, net capital expenditures were $1.002 billion, which primarily related to the purchase of 24 new 737-700 aircraft, and progress payments for future aircraft deliveries.

The Company's contractual commitments consist primarily of scheduled aircraft acquisitions. As a result of the September 11, 2001 terrorist attacks, the Company was able to modify its future aircraft delivery dates. As of November 13, 2001, the Company has no new aircraft deliveries scheduled for the remainder of 2001, 11 737-700s scheduled for delivery in 2002, 21 in 2003, 23 in 2004, 24 in 2005, 22 in 2006, 25 in 2007, and 6 in 2008. The Company also has a total of 87 purchase options for new 737-700 aircraft for years 2003 through 2008 as follows: 13 in 2004, 20 in 2005, 20 in 2006, 9 in 2007, and 25 in 2008. In total, Southwest's firm orders, options, and purchase rights through 2012 have remained unchanged at 436 aircraft. 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 2002. Based on these recent modifications, aggregate funding needed for fixed commitments at November 13, 2001, was approximately $3.650 billion due as follows: $2 million in 2001; $322 million in 2002; $687 million in 2003; $670 million in 2004; $706 million in 2005; and $1.263 billion thereafter.

The Company has various options available to meet its capital and operating commitments, including cash on hand at September 30, 2001 of $1.49 billion and internally generated funds. In addition, the Company will also consider various borrowing or leasing options to maximize earnings and supplement cash requirements.

On October 11, 2001, the Company filed a registration statement on Form S-3 covering an additional $1.0 billion principal amount of unsecured debt securities and pass through certificates which may be publicly offered from time to time. The registration statement was declared effective by the SEC on October 15, 2001. Subsequent to the Company's issuance of $614.3 million Pass Through Certificates on October 30, 2001, as discussed in Note 11 to the unaudited Condensed Consolidated Financial Statements, the Company has outstanding shelf registrations for the issuance of an additional $704.5 million in public debt securities and pass through certificates. The Company could utilize these to pay down short-term borrowings and/or finance aircraft during 2001 and 2002.

In July 2001, the Company redeemed $100 million of senior unsecured 9.4% Notes originally issued in 1991.

The Company recently began new service to Norfolk International Airport in Norfolk, Virginia. Service began on October 7, 2001, with daily nonstop flights from Baltimore/Washington, Jacksonville, Las Vegas, and Orlando, plus direct or connecting service from 32 other cities.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

The Company received a statutory notice of deficiency from the Internal Revenue Service (IRS) in July 1995 in which the IRS proposed to disallow 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 response to the statutory 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 there is no deficiency in the Company's tax liability for the taxable years in issue. On December 21, 2000, the national office of the IRS published a revenue ruling in which it concluded that aircraft inspection and maintenance is currently deductible as an ordinary and necessary business expense. In accordance with the revenue ruling, the IRS conceded the proposed adjustments to the deductions claimed by the Company for aircraft inspection and maintenance expense, and on June 1, 2001, a decision was entered by the Tax Court holding that there is no deficiency in income tax for the taxable years 1989 through 1991.

The IRS similarly proposed to disallow deductions claimed by the Company on its federal income tax returns for the taxable years 1992 through 1994 for the costs of certain aircraft inspection and maintenance expenses. Although the examination of such returns has not been finally concluded, the IRS has advised the Company that it will concede the proposed adjustments to the deductions claimed for these aircraft inspection and maintenance expenses. Management believes the final resolution of this controversy will not have a material adverse effect upon the financial position or results of operations of the Company.

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.

P.A. No. 1810
K/SWA SA-17


Southwest Airlines Co.
6-1162-RLL-933R10 Page 4

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. Price.

3.1 The advance payment base prices of the Option Aircraft set forth below and in paragraph 2.1 of Attachment A represent the estimated delivery prices of the Option Aircraft. The Option Aircraft pricing elements and associated pricing terms and conditions are given in Attachment A.

3.2 Price and escalation provisions for Model 737-7H4 aircraft delivering after 2004 are not currently available.

3.3 The Advance Payment Base Prices of the Option Aircraft indicated below do include an amount for special features in addition to those specifically described in Attachment A but do not include any amount for items of Buyer Furnished Equipment (BFE). An estimate for typical special features is *** per Aircraft (expressed in 1992 STE dollars) and for BFE is *** per Aircraft (expressed in delivery year dollars).

P.A. No. 1810

Southwest Airlines Co.

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 sixteen (16) 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

P.A. No. 1810
K/SWA SA-17


Southwest Airlines Co.
6-1162-RLL-933R10 Page 7

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, with interest, to Buyer. The interest rate for calculation of the interest associated with such refund is the rate of two percent (2%) below the Citibank base rate in effect from time to time during the period the Option deposit is held by Boeing.

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

P.A. No. 1810
K/SWA SA-17


Southwest Airlines Co.
6-1162-RLL-933R10 Page 8

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

(a) Buyer hereby accepts the assignment and sale contained in

(b) Each Aircraft is scheduled to be delivered by the Manufacturer under the Purchase Agreement during the respective months set forth in Column (B) of Schedule 1 hereto.

[Purchase Agreement Assignment]

or product support agreement of the Manufacturer, the Engine Manufacturer or any subcontractor or vendor in respect of the Aircraft, except that Seller may not enter into any change order or other amendment, modification or supplement to the Purchase Agreement or the Engine Warranties without Buyer's prior written consent if such change order, amendment, modification or supplement would result in any rescission, cancellation or termination of the Purchase Agreement or the Engine Warranties as to the Aircraft or materially diminish the rights and interests assigned hereunder, and (2) Buyer shall, at Seller's expense, cooperate with Seller and take such actions as Seller reasonably deems necessary to enable Seller to enforce such rights and claims.

(b) Effective upon the receipt by the Manufacturer and the Engine Manufacturer of written notice from the Indenture Trustee that an Indenture Event of Default has occurred and is continuing and thereafter until the Manufacturer and the Engine Manufacturer shall have received written notice from the Indenture Trustee that such Indenture Event of Default has been cured or waived, unless the Indenture Trustee, in its sole discretion shall notify Manufacturer and the Engine Manufacturer to the contrary, the authorization given to Seller under Section 5(a) hereof to enforce such rights and claims shall thenceforth cease to be effective and Buyer and its successors and permitted assigns shall, to the exclusion of Seller, be entitled to assert and enforce such rights and claims as substitute party plaintiff or otherwise, and Seller shall, at the request of Buyer or its successors or permitted assigns and at Seller's expense, cooperate with and take such action as is reasonably necessary to enable Buyer and its successors and permitted assigns to enforce such rights and claims. In furtherance of the foregoing, Seller hereby constitutes and appoints Buyer, its successors and permitted assigns, Seller's true and lawful attorney, irrevocably (it being acknowledged that such appointment is coupled with an interest, namely Buyer's rights acquired and to be acquired hereunder) with full power (in the name of Seller or otherwise) to ask, require, demand, receive, compromise, settle, compound and give acquittance for any and all monies and claims for monies due and to become due under, or arising out of, the Purchase Agreement in respect of the Aircraft, to the extent that the same have been assigned by this Assignment, and for such period as Buyer may exercise rights with respect thereto hereunder, to endorse any checks or other instruments or orders in connection therewith and to file any claims or take any action or institute (or, if previously commenced, assume control of) any proceedings and to obtain any recovery in connection therewith that Buyer may deem to be necessary or advisable in the premises.

(c) For all purposes of this Assignment, the Manufacturer and the Engine Manufacturer shall not be deemed to have knowledge of an Indenture Event of Default or of the discontinuance or waiver of an Indenture Event of Default unless and until the Manufacturer and the Engine Manufacturer shall have received written notice (including by mail, telex or telecopy) thereof from the Indenture Trustee addressed, if to the Manufacturer, to the Vice President - Contracts at P.O. Box 3707, Mail Code 21-34, Seattle, Washington 98124, if by mail and to 32-9430 (Answerback BOEINGREN RNTN), if by telex and to (425) 237-1706, if by telecopy, and, if to the Engine Manufacturer, to the Director of Commercial Contracts at 1 Newman Way, Cincinnati Ohio 45215, if by mail and to

[Purchase Agreement Assignment]

SECTION 6. Certain Rights and Obligations of the Parties.

(a) Anything herein contained to the contrary notwithstanding:
(i) Seller shall at all times remain liable to the Manufacturer and the Engine Manufacturer under the Purchase Agreement and the General Terms Agreement in respect of the Aircraft to perform all of its duties and obligations of "Buyer" thereunder to the same extent as if this Assignment had not been executed; (ii) the exercise by Buyer of any of the rights assigned hereunder shall not release Seller from any of its duties or obligations to the Manufacturer and the Engine Manufacturer under the Purchase Agreement or the General Terms Agreement in respect of the Aircraft except to the extent that such exercise by Buyer shall constitute performance of such duties and obligations; and (iii) Seller shall at all times remain liable to perform the obligations of "Buyer" under Part E of Exhibit C of the Purchase Agreement.

(b) Without in any way releasing Seller from any of its duties or obligations under the Purchase Agreement and the General Terms Agreement, Buyer confirms for the benefit of the Manufacturer and the Engine Manufacturer, that, insofar as the provisions of the Purchase Agreement and the General Terms Agreement relate to the Aircraft, in exercising any rights under the Purchase Agreement or the General Terms Agreement, or in making any claim with respect to the Aircraft or other goods and services delivered or to be delivered pursuant to the Purchase Agreement or the General Terms Agreement, the terms and conditions of the Purchase Agreement (including, without limitation, those relating to any exclusion or limitation of liabilities or warranties as set forth in Article 12 thereof or those relating to any indemnity and insurance as set forth in Exhibit C, Part E thereof) or the General Terms Agreement, as the case may be, shall apply to, and be binding upon, Buyer to the same extent as Seller.

(c) Seller and Buyer agree, expressly for the benefit of the Manufacturer and the Engine manufacturer, that nothing contained herein shall
(i) subject the Manufacturer or the Engine Manufacturer to any liability to which it would not otherwise be subject under the Purchase Agreement or the General Terms Agreement, (ii) modify in any respect the Manufacturer's or the Engine Manufacturer's contract rights thereunder, except as provided in the Consent and Agreement and the Engine Consent and Agreement, respectively or
(iii) require the Manufacturer to divest itself of title to or possession of the Aircraft until delivery thereof and payment therefor as provided in the Purchase Agreement.

(d) The parties hereto, and the Manufacturer and the Engine Manufacturer by its respective execution and delivery of the Consent and Agreement and the Engine Consent and Agreement, agree that all of the statements, representations, covenants and agreements made by Buyer acting through the Owner Trustee (when made in such capacity) contained in this Assignment and any agreement referred to herein (other than the Trust Agreement), unless expressly otherwise stated, are made and intended only for the purpose of binding the Trust Estate and establishing the existence of rights and remedies which can be exercised and enforced only against the Trust Estate. Therefore, anything contained in this Assignment or such other agreements to the contrary notwithstanding (except for any express provisions that Owner Trustee is responsible for in its individual capacity), no recourse shall be had with respect to this Assignment or such other agreements against the Owner Trustee in its individual capacity (or against any institution or person which becomes a successor trustee or co-trustee) or any officer, director, trustee, servant or direct or indirect parent or controlling person or persons of any of

6

[Purchase Agreement Assignment]

them; provided, however, that this Section 6(d) shall not be construed to prohibit any action or proceeding against the Owner Trustee in its individual capacity for its own willful misconduct or grossly negligent conduct; and provided, further, that nothing contained in this Section 6(d) shall be construed to limit the exercise and enforcement in accordance with the terms of this Assignment or such other agreements of rights and remedies against the Trust Estate. The foregoing provisions of this Section 6(d) shall survive the termination of this Assignment and the other Operative Agreements.

SECTION 7. Further Assignment. In order to secure the repayment of, inter alia, the Certificates, Buyer has agreed in the Indenture, among other things, to assign to the Indenture Trustee all of Buyer's right, title and interest in and to the Purchase Agreement (as it relates to the Aircraft) and this Assignment, and Seller hereby consents to such assignment.

SECTION 8. Further Assurances. Seller agrees that at any time and from time to time Seller shall promptly and duly execute and deliver any and all such further instruments and documents and take such further action as Buyer may reasonably request in writing in order to obtain the full benefits of this Assignment and of the rights and powers herein granted. Seller shall provide a Deferred Delivery Date Notice to the Manufacturer, the Engine Manufacturer and the Indenture Trustee with respect to any proposed reassignment of the Purchase Agreement and the Engine Warranties in connection with the sale of an Aircraft by Buyer to Seller not less than five Business Days prior to such sale. Buyer agrees, expressly for the benefit of Manufacturer and the Engine Manufacturer, that at any time and from time to time upon the written request of Manufacturer or the Engine Manufacturer, as the case may be, Buyer shall promptly and duly execute and deliver any and all such further assurances, instruments and documents and take all such further action as Manufacturer or the Engine Manufacturer, as the case may be, may reasonably request in order to obtain the full benefits of Buyer's agreements hereunder.

SECTION 9. No Amendment of Purchase Agreement or General Terms Agreement. Buyer agrees that it will not enter into any amendment, modification, supplement, rescission, cancellation or termination of the Purchase Agreement or the General Terms Agreement without the prior written consent of Seller unless the Indenture Trustee shall have notified Manufacturer and the Engine Manufacturer that an Indenture Event of Default has occurred and is continuing.

SECTION 10. Nondisclosure. Seller and Buyer agree, expressly for the benefit of the Manufacturer and the Engine Manufacturer, that they will not disclose the terms of the Purchase Agreement or the General Terms Agreement to any third party, except (a) as required by applicable laws or governmental regulations, (b) with the prior written consent of the Manufacturer or the Engine Manufacturer, as applicable, (c) to Indenture Trustee and the Loan Participants and to potential transferees thereof and their respective counsel. Any disclosure contemplated by clause (c) of the preceding sentence shall include a requirement that the entity to whom such information is disclosed shall be subject to obligations of nondisclosure with respect to such information substantially the same as those contained herein.

SECTION 11. Miscellaneous.

(a) This Assignment shall be binding upon and shall inure to the benefit of Seller, Buyer and their respective successors and permitted assigns.

(d) This Assignment may be executed by the parties hereto in separate counterparts, each of which when so executed and delivered shall be an original, but all such counterparts shall together constitute one and the same instrument.
