                            Southwest Airlines Co.
            Notes to Condensed Consolidated Financial Statements
                                 (unaudited)


1.  BASIS OF PRESENTATION 

The accompanying unaudited condensed consolidated financial statements of
Southwest Airlines Co. (Company or Southwest) 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
unaudited condensed consolidated financial statements for the interim 
periods ended June 30, 2005 and 2004, include all adjustments, which are, in
the opinion of management, necessary for a fair presentation of the results
for the interim periods.  This includes all normal and recurring adjustments,
and other accounting entries as described herein.  The Condensed Consolidated
Balance Sheet as of December 31, 2004, has been derived from the Company's
audited financial statements as of that date but does not include all of the
information and footnotes required by generally accepted accounting
principles for complete financial statements.  Financial results for the
Company, and airlines in general, are seasonal in nature.  Historically, the
Company's second and third fiscal quarters have been more profitable than its
first and fourth fiscal quarters.  Operating results for the three and six
months ended June 30, 2005, are not necessarily indicative of the results 
that may be expected for the year ended December 31, 2005.  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, 2004.

Certain prior period amounts have been reclassified to conform to the current
presentation.  In the Condensed Consolidated Balance Sheet as of December 31,
2004, the Company has reclassified certain amounts as "Short-term
investments", that were previously classified as "Cash and cash equivalents." 
In the Condensed Consolidated Statement of Cash Flows for the three and six 
months ended June 30, 2004, changes in the amounts of "Short-term
investments" are classified as cash flows from investing activities.  In the 

Condensed Consolidated Statement of Income for the three and six months ended
June 30, 2004, amounts previously classified as "Agency commissions" are now
classified in "Other operating expenses."

The Company has stock-based compensation plans covering the majority of its
Employee groups, including plans adopted via collective bargaining, a plan
covering the Company's Board of Directors, and plans related to employment
contracts with certain Executive Officers of the Company.  The Company
accounts for stock-based compensation utilizing the intrinsic value method 
in accordance with the provisions of Accounting Principles Board Opinion No.
25 (APB 25), "Accounting for Stock Issued to Employees" and related
Interpretations.  Accordingly, no compensation expense is recognized for
fixed option plans because the exercise prices of Employee stock options
equal or exceed the market prices of the underlying stock on the dates of 
grant.  See Note 10 for additional information.

The following table represents the effect on net income and earnings per
share if the Company had applied the fair value based method and recognition
provisions of Statement of Financial Accounting Standards (SFAS) No. 123,
"Accounting for Stock-Based Compensation," to stock-based Employee
compensation (in millions, except per share amounts):

5. FINANCIAL DERIVATIVE INSTRUMENTS

Fuel Contracts - Airline operators are inherently dependent upon energy to
operate and, therefore, are impacted by changes in jet fuel prices.  Jet fuel
and oil consumed in the three month periods ended June 30, 2005 and 2004,
represented approximately 19.8 percent and 16.2 percent, respectively, of
Southwest's operating expenses for those periods.  The Company endeavors to 
acquire jet fuel at the lowest possible prices.  Because jet fuel is not
traded on an organized futures exchange, liquidity for jet fuel hedging is
limited.  However, the Company has found commodities for effective hedging of
jet fuel costs, primarily crude oil, heating oil, and unleaded gasoline.  The 
Company utilizes financial derivative instruments as hedges 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.  In addition to the significant hedging positions the
Company had in place for the first six months of 2005, the Company also has
significant future hedging positions.  The Company currently has a mixture of
purchased call options, collar structures, and fixed price swap agreements in
place to hedge approximately 85 percent of its remaining 2005 total

anticipated jet fuel requirements that effectively cap crude oil-equivalent
prices at $26 per barrel.  As of June 30, 2005, the "spot" market price for a
barrel of crude oil was over $56 and "futures" prices for the subsequent 12 
months all exceeded this "spot" price.  The Company is also approximately 65
percent hedged for 2006 at approximately $32 per barrel, over 45 percent
hedged for 2007 at approximately $31 per barrel, approximately 30 percent
hedged for 2008 at approximately $33 per barrel, and approximately 25 percent
hedged for 2009 at approximately $35 per barrel.  As of June 30, 2005, the
majority of the Company's remaining 2005 hedges are effectively in the form
of unleaded gasoline-based and heating oil-based option contracts.  The
majority of the remaining hedge positions are crude oil-based positions. 

The fair value of the Company's financial derivative instruments at June 30,
2005, was a net asset of approximately $1.8 billion.  The current portion of
this net asset, approximately $717 million, is classified as "Fuel hedge
contracts" and the noncurrent portion, approximately $1.04 billion, is
classified in "Other assets" in the Condensed Consolidated Balance Sheet. 
The fair value of the derivative instruments, depending on the type of
instrument, was determined by the use of present value methods or standard
option value models with assumptions about commodity prices based on those
observed in underlying markets.

During the three months ended June 30, 2005 and 2004, the Company recognized
$196 million and $87 million in gains in "Fuel and oil" expense,
respectively, from hedging activities.  The Company also recognized
approximately $9 million and $6 million of net expense, respectively, related
to amounts excluded from the Company's measurements of hedge effectiveness,
in "Other (gains) losses, net" during second quarter 2005, and second quarter
2004.  During the three months ended June 30, 2005, the Company also
recognized approximately $2 million of additional expense in "Other (gains)
losses, net," related to the ineffectiveness of its hedges. During the three
months ended June 30, 2004, the Company recognized approximately $5 million
of additional expense in "Other (gains) losses, net," related to the
ineffectiveness of its hedges.  

The Company accounts for its fuel hedge derivative instruments as cash flow
hedges, as defined in Statement of Financial Accounting Standards No. 133,
Accounting for Derivative Instruments and Hedging Activities, as amended
(SFAS 133). Under SFAS 133, all derivatives designated as hedges that meet
certain requirements are granted special hedge accounting treatment. 
Generally, utilizing the special hedge accounting, all periodic changes in
fair value of the derivatives designated as hedges that are considered to be
effective, as defined, are recorded in "Accumulated other comprehensive
income" until the underlying jet fuel is consumed.  However, the Company is
exposed to the risk that periodic changes will not be effective, as defined,
or that the derivatives will no longer qualify for special hedge accounting. 
To the extent that the periodic changes in the fair value of the derivatives
are not effective, or if the hedge ceases to qualify for hedge accounting,
those periodic non-cash changes are recorded as ineffectiveness to "Other
gains and losses" in the income statement in the period of the change. 

Ineffectiveness is inherent in hedging jet fuel with derivative positions
based in other crude oil related commodities, especially given the magnitude
of the current fair market value of the Company's fuel hedge derivatives. 
Due to the volatility in markets for crude oil and crude oil related


products, the Company is unable to predict the amount of ineffectiveness each
period, including the loss of hedge accounting (which could be determined on a
derivative by derivative basis or in the aggregate), which may result in
increased volatility in the Company's results. The significant increase in the
amount of noncash ineffectiveness recorded during the first six months of 2005
was primarily due to the significant increase in energy prices compared to prior
periods, the number of derivative positions the Company holds, as well as the
volatility of the different types of products the Company uses in hedging-
specifically between crude oil and heating oil.  As the fair value of the
Company's hedge positions gets larger in amount, there is a higher degree of
probability that there will be more variability in noncash ineffectiveness
recorded in the income statement as small differences in the correlation of
crude oil related products are leveraged over large dollar volumes.

As of June 30, 2005, the Company had approximately $1.0 billion in unrealized
gains, net of tax, in "Accumulated other comprehensive income" related to
fuel hedges.  Included in this total are approximately $412 million in net
unrealized gains (net of tax) that are expected to be realized in earnings
during the twelve months following June 30, 2005.  

Interest Rate Swaps - In previous periods, the Company has entered into
interest rate swap agreements relating to its $350 million 5.25% senior
unsecured notes due October 1, 2014, its $385 million 6.5% senior unsecured
notes due March 1, 2012 and its $375 million 5.496% Class A-2 pass-through
certificates due November 1, 2006.  Under these interest rate swap
agreements, the Company pays the London InterBank Offered Rate (LIBOR) plus a
margin every six months on the notional amount of the debt, and receives the 
fixed stated rate of the notes every six months until the date the notes
become due.  

The Company's interest rate swap agreements qualify as fair value hedges, as
defined by SFAS 133. The fair value of the interest rate swap agreements,
which are adjusted regularly, are recorded in the Company's balance sheet as
an asset or liability, as necessary, with a corresponding adjustment to the 
carrying value of the long-term debt.  The fair value of the interest rate
swap agreements, excluding accrued interest, at June 30, 2005 was a liability 

of approximately $3 million.  This amount is recorded in "Other deferred
liabilities" in the unaudited Condensed Consolidated Balance Sheet.  In 
accordance with fair value hedging, the offsetting entry is an adjustment to
decrease the carrying value of long-term debt.  

6. COMPREHENSIVE INCOME

Comprehensive income included 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 first six months of 2005,
the Company's comprehensive income increased significantly, due to the 
substantial change in the fair value of the Company's hedge positions.  Since
comprehensive income is reported net of tax, there was also a significant
increase in the Company's deferred tax liability compared to December 31,
2004.  See Note 5 for further information.  Comprehensive income totaled $187
million and $818 million, respectively, for the three and six months ended
June 30, 2005.  Comprehensive income totaled $215 million and $304 million,
respectively, for the three and six months ended June 30, 2004.  The
differences between net income and comprehensive income for each of these
periods was as follows (in millions):

7. LONG-TERM DEBT

During February 2005, the Company issued $300 million senior unsecured Notes
(Notes) due 2017.  The Notes bear interest at 5.125 percent, payable semi-
annually in arrears, with the first payment due on September 1, 2005. 
Southwest used the net proceeds from the issuance of the Notes, approximately
$296 million, for general corporate purposes.

During first quarter 2005, the Company redeemed its $100 million senior
unsecured 8% Notes on their maturity date of March 1, 2005.

10. RECENTLY ISSUED ACCOUNTING STANDARDS

In December 2004, the FASB issued SFAS No. 123R, "Share-Based Payment".  SFAS
No. 123R is a revision of SFAS No. 123, "Accounting for Stock Based
Compensation", and supersedes APB 25.  Among other items, SFAS 123R
eliminates the use of APB 25 and the intrinsic value method of accounting,
and requires companies to recognize the cost of employee services received in 
exchange for awards of equity instruments, based on the grant date fair value
of those awards, in the financial statements.  The effective date of SFAS
123R had been set for the first reporting period beginning after June 15,
2005, which is third quarter 2005 for calendar year companies, although. 
However, on April 14, 2005, the Securities and Exchange Commission (SEC) 
announced that the effective date of SFAS 123R was suspended until January 1,
2006, for calendar year companies.  Early adoption, however, is allowed.

SFAS 123R permits companies to adopt its requirements using either a
"modified prospective" method, or a "modified retrospective" method.  Under
the "modified prospective" method, compensation cost is recognized in the
financial statements beginning with the effective date, based on the
requirements of SFAS 123R for all share-based payments granted after that
date, and based on the requirements of SFAS 123 for all unvested awards
granted prior to the effective date of SFAS 123R.  Under the "modified
retrospective" method, the requirements are the same as under the "modified
prospective" method, but also permits entities to restate financial
statements of previous periods based on proforma disclosures made in 

accordance with SFAS 123. 

The Company currently utilizes a standard option pricing model (i.e., Black-
Scholes) to measure the fair value of stock options granted to Employees. 
While SFAS 123R permits entities to continue to use such a model, the
standard also permits the use of a "lattice" model.  The Company has not yet
determined which model it will use to measure the fair value of employee
stock options upon the adoption of SFAS 123R.  
 
SFAS 123R also requires that the benefits associated with the tax deductions
in excess of recognized compensation cost be reported as a financing cash
flow, rather than as an operating cash flow as required under current
literature.  This requirement will reduce net operating cash flows and
increase net financing cash flows in periods after the effective date.  These
future amounts cannot be estimated because they depend on, among other
things, when employees exercise stock options.  

The Company currently expects to adopt SFAS 123R effective January 1, 2006,
based on the new effective date announced by the SEC; however, the Company
has not yet determined which of the aforementioned adoption methods it will
use.  In addition, the Company has not yet determined the financial statement
impact of adopting SFAS 123R for periods beyond 2005.

Material Changes in Results of Operations

      Summary

     The Company's second quarter 2005 net income was $159 million ($.20 per
share, diluted), an increase of $46 million, or 40.7 percent, compared to
second quarter 2004 net income of $113 million ($.14 per share, diluted). 
Despite a persistently challenging operating environment for all airlines,
second quarter 2005 represented the Company's 57th consecutive quarterly
profit.  The price of fuel, typically an airline's second largest expense
after labor, reached new record-high levels again in June 2005.  Fortunately,
the Company's hedging program once again greatly mitigated these record-high
market fuel prices during second quarter 2005, as hedging gains reduced fuel
and oil expense by $196 million.  See Note 5 to the unaudited condensed
consolidated financial statements.  However, even with the Company's strong
hedge position, fuel cost per gallon increased 24.5 percent versus second
quarter 2004.  

     Second quarter 2005 operating income increased $80 million, or 40.6
percent, compared to second quarter 2004, primarily due to an excellent cost
performance and a 13.3 percent increase in revenues.  The increase in
revenues primarily resulted from the 13.7 percent increase in the Company's
capacity (available seat mile).  Although the Company's load factor was down
3.8 points from last year's record performance of 76.3 percent, RPM yields
improved 4.6 percent as a result of modest fare increases, and improved fare
mix, and the success of the Company's codeshare arrangement with ATA Airlines 

(ATA.)  The codeshare agreement with ATA, which began in first quarter 2005,
has since been expanded to include additional flights, and has been more
successful than the Company had originally anticipated.  The Company expects
the code share agreement to generate a total of $50 million in additional
passenger revenue annually.

     The Company continued its focus on controlling non-fuel costs.  Second
quarter 2005 CASM (cost per available seat mile) decreased 3.5 percent
compared to the prior year, and excluding fuel, CASM decreased 7.7 percent. 
A portion of the CASM decrease was due to two separate second quarter 2004
charges-$11 million in bonus pay and benefits associated with the more than
1,000 Employees that left the Company due to a voluntary early out option
offered to all Employees, except officers; and $12 million in pay and
benefits associated with a labor agreement (contract) for the Company's Flight
Attendants reached during second quarter 2004.  Excluding these second
quarter 2004 charges, year-over-year unit costs were also down.  The decrease
was due to declines in almost every nonfuel cost
category, which more than offset the large increase in fuel costs.  As a
result of increased workforce productivity, the Company has been able to
expand flights while simultaneously keeping overall headcount flat.  At June
30, 2005, the Company's headcount per aircraft was 72 versus a year-ago level
of 78.  These productivity enhancements have helped the Company absorb cost
pressures from wage and benefit increases.  

     For the six months ended June 30, 2005, net income was $235 million
($.29 per share, diluted), an increase of $96 million, or 69.1 percent,
compared to the comparable period of 2004 net income of $139 million ($.17
per share, diluted).  Operating income for the six months ended June 30, 2005
increased $140 million, or 57.6 percent compared to the same period of 2004. 
This significant increase in operating income was primarily due to the
strengthening airline revenue environment and to the Company's ongoing cost
reduction efforts, which resulted in a 5.8 percent decrease in CASM,
excluding fuel.

     Based on recent trends, the Company expects third quarter 2005 unit
costs, excluding fuel, to be in line with second quarter 2005's unit cost of
6.27 cents per ASM.  The Company began service to Pittsburgh, Pennsylvania,
in May 2005, and plans to add more flights later this year.  The Company also
announced that it will begin service to Fort Myers, Florida, in October 2005. 
Fort Myers will represent the 61st city the Company serves.  

Comparison of three months ended June 30, 2005, to three months ended June
30, 2004
              
Revenues

     Consolidated operating revenues increased by $228 million, or 13.3
percent, primarily due to a $214 million, or 12.9 percent, increase in
passenger revenues.  The increase in passenger revenues was primarily due to
an 8.1 percent increase in revenue passenger miles (RPMs) flown.  

     Second quarter 2005 capacity, as measured by available seat miles
(ASMs), increased 13.7 percent compared to second quarter 2004.  The capacity
increase resulted from the net addition of 29 aircraft (net of 18
retirements) since the end of second quarter 2004.  The second quarter 2005
load factor was 72.5 percent, a decrease of 3.8 points compared to the same 

period of 2004.  The Company also experienced a 6.5 percent increase in
revenue passengers carried compared to second quarter 2004.

     The second quarter 2005 passenger yield per RPM increased 4.6 percent to
12.07 cents from 11.54 cents in second quarter 2004.  The higher RPM yield
was primarily due to modest fare increases and an improved fare mix versus
second quarter 2004.  Unit revenue (operating revenue per ASM) decreased
slightly, however, as the higher RPM yields and stronger freight and other
revenues did not fully offset the lower load factor.  Revenue trends were
also favorably impacted by the Company's recent codeshare agreement with ATA
Airlines, Inc.  The Company's load factor and unit revenue trends have
continued to improve thus far in July 2005.  Based on bookings and these
traffic trends, the Company expects third quarter 2005 unit revenue results to
exceed the third quarter 2004 unit revenue of 8.59 cents, despite year-over-year
capacity growth of approximately 12 percent.  
	
     Consolidated freight revenues increased by $5 million, or 17.9 percent. 
Approximately 57 percent of the increase was due to an increase in freight
and cargo revenues, primarily as a result of the increase in capacity versus
second quarter 2004.  The remainder of the increase was in mail revenues, as
the U.S. Postal Service shifted more business to commercial carriers.  The
Company expects year-over-year freight revenue growth in third quarter 2005,
although at a lower rate than in second quarter 2005.  Other revenues
increased by $9 million, or 26.5 percent, compared to second quarter 2004. 
Approximately half of the increase was in excess baggage charges, as the
Company modified its fee policy related to the weight of checked baggage. 
The remainder of the increase was spread among other items, including
commissions earned from programs the Company sponsors with certain business
partners, such as the Company sponsored Chase Visa card, and charter
revenues.  The Company expects another year-over-year other revenue increase
in third quarter 2005; however, at a lower rate than in second quarter 2005.

Operating expenses

     To a large extent, changes in operating expenses for airlines are driven
by changes in capacity, or ASMs.  The following presents Southwest's
operating expenses per ASM for the three months ended June 30, 2005 and 2004,
followed by explanations of changes on a per-ASM basis:


                              Three months ended June 30,   Per ASM   Percent
                                  2005         2004         Change    Change
                                                           
Salaries, wages, and benefits     3.13         3.31          (.18)     (5.4)
Fuel and oil                      1.55         1.31           .24      18.3
Maintenance materials
  and repairs                      .50          .66          (.16)    (24.2)
Aircraft rentals                   .20          .24          (.04)    (16.7)
Landing fees and other rentals     .53          .53             -         -
Depreciation                       .54          .57          (.03)     (5.3)
Other operating expenses          1.36         1.47          (.11)     (7.5)

Total                             7.81         8.09          (.28)      3.5 





 
     Operating expenses per ASM were 7.81 cents, a 3.5 percent decrease
compared to 8.09 cents for second quarter 2004.  Approximately one-third of the
year-over-year CASM decrease was due to second quarter 2004 costs incurred
associated with the Company's voluntary early-out plan offered to all
Employees except officers, and charges associated with the Company's labor
agreement with its Flight Attendants.  Excluding these 2004 items, year-over-
year CASM decreased primarily due to lower maintenance costs and lower
salaries, wages, and benefits, partially offset by higher fuel and oil
expense.  Excluding fuel, CASM was 7.7 percent lower than second quarter
2004, at 6.27 cents per ASM.

     Salaries, wages, and benefits expense per ASM decreased 5.4 percent.  In
second quarter 2004, salaries, wages, and benefits included approximately $11
million of bonus pay and benefits associated with the Company's voluntary
early-out plan offered to all Employees except officers, and approximately $7
million in pay and benefit increases associated with the Company's labor 
agreement with its Flight Attendants (an additional $5 million related to per
diem increases was included in "Other operating expenses").  Excluding these
2004 items and their related profitsharing impact, salaries, wages, and 
benefits decreased 3.1 percent compared to the prior year, as higher Employee
productivity more than offset higher average wage rates and higher
profitsharing expense per ASM.  Continued productivity efforts have enabled
the Company to reduce headcount while continuing to grow its capacity.  The
Company expects Salaries, wages, and benefits in third quarter 2005 to be
flat or slightly up compared to the 3.14 cents per ASM experienced in third
quarter 2004.

     Fuel and oil expense per ASM increased 18.3 percent primarily due to an
increase in the average jet fuel price per gallon.  The average fuel cost per
gallon in second quarter 2005 was $1.02, 24.5 percent higher than second
quarter 2004, including the effects of hedging activities.  Prior to second
quarter 2005, the Company had hedged approximately 85 percent of its fuel
needs. This resulted in second quarter gains recorded in fuel and oil expense
of $196 million.  In other efforts to control fuel expense, the Company has
added Blended Winglets to all of its Boeing 737-700 aircraft.  These
enhancements extend the range of these aircraft, enable the aircraft to burn
less fuel, lower potential engine maintenance costs, and reduce takeoff
noise.  All new 737-700 aircraft now arrive from Boeing with winglets already
installed.  The Company expects annual fuel consumption savings of
approximately three percent for each aircraft outfitted with the winglets.
For third quarter 2005, the Company has fuel hedges in place for
approximately 83 percent of its expected fuel consumption with a combination
of derivative instruments that effectively cap prices at approximately $26
per barrel of crude oil.  The majority of the Company's near term hedge
positions are in the form of option contracts.  During the first six months
of 2005, because of the continued rise in energy prices, the fair values of
the Company's fuel hedge contracts have increased significantly.  At June 30,
2005, the estimated net fair value of these contracts was $1.8 billion.  See
Note 5 to the unaudited condensed consolidated financial statements for
further discussion of the Company's hedging activities.
	
     Maintenance materials and repairs per ASM decreased 24.2 percent
primarily due to a decrease in repair events for aircraft engines.  The
Company currently expects a year-over-year decline in maintenance materials
and repairs per ASM for third quarter 2005.  The anticipated decrease is
primarily due to less scheduled maintenance activity, although the year-over-

year change is expected to be lower than that experienced in second quarter
2005.  

     Aircraft rentals per ASM decreased 16.7 percent compared to second
quarter 2004.  The majority of the decrease per ASM was due to the Company's
growth occurring with purchased aircraft.  All of the aircraft acquired in
2004, except for one, and all of the aircraft acquired in 2005, are owned by
the Company.  The Company currently expects a similar year-over-year decline
in aircraft rentals per ASM for third quarter 2005.
	
     Depreciation expense per ASM decreased 5.3 percent, primarily due to the
retirement of equipment associated with the Company's 737-200 aircraft, the
remainder of which were phased out of the Company's fleet in January 2005. 
For third quarter 2005, the Company currently expects depreciation per ASM to
be comparable to second quarter 2005.

     Other operating expenses per ASM decreased 7.5 percent compared to
second quarter 2004.  Approximately half of the decrease was due to lower
advertising expense, primarily due to higher promotional activity in second
quarter 2004 associated with fare sales and the Company's initiation of
service to Philadelphia.  The remainder of the decrease was primarily due to
lower personnel costs and lower insurance costs.  These and other smaller
decreases were partially offset by higher fuel sales taxes due to the
substantial increase in fuel prices.  The Company currently expects Other 
operating expenses per ASM for third quarter 2005 to be flat or slightly down
compared to the 1.36 cents per ASM experienced in second quarter 2005.  

     Through the 2003 Emergency Wartime Supplemental Appropriations Act, the
federal government has continued to provide supplemental third-party war-risk
insurance coverage to commercial carriers for renewable 60-days periods, at
substantially lower premiums than prevailing commercial rates and for levels
of coverage not available in the commercial market.   The government-provided
supplemental coverage from the Wartime Act is set to expire on August 31,
2005, but is expected to be extended to December 31, 2005.  If such coverage
is not extended by the government beyond either of these dates, the Company
could incur substantially higher insurance costs.  


Other

     Interest expense increased $7 million, or 31.8 percent compared to
second quarter 2004.  The majority of the increase was due to the issuance of
new debt, including the Company's September 2004 issuance of $350 million
senior unsecured Notes, fourth quarter 2004 issuance of $112 million of
French credit agreements, and the February 2005 issuance of $300 million
senior unsecured Notes. These new issuances were partially offset by the
November 2004 redemption of $175 million aircraft secured Notes, and the
March 2005 redemption of $100 million senior unsecured Notes.  See Note 7 
to the unaudited condensed consolidated financial statements for more
information.

     Capitalized interest decreased by $1 million, or 10.0 percent, primarily
due to a decrease in progress payment balances for future aircraft
deliveries.  



     Interest income increased by $5 million, or 100.0 percent, primarily due
to an increase in rates earned on cash and higher investment balances.  

     "Other (gains) losses, net" primarily includes amounts recorded in
accordance with SFAS 133.  See Note 5 to the unaudited condensed consolidated
financial statements for more information on the Company's hedging
activities.  During second quarter 2005, the Company recognized approximately
$9 million of expense related to amounts excluded from the Company's 
measurements of hedge effectiveness and $2 million in expense related to the
ineffectiveness of its hedges.  In second quarter 2004, the Company
recognized approximately $6 million of expense related to amounts excluded
from the Company's measurements of hedge effectiveness and $5 million in
income related to the ineffectiveness of its hedges. 

     The Company's effective tax rate increased to 38.1 percent in second
quarter 2005 from 36.8 percent in second quarter 2004.  The majority of the
increase was primarily due to the Company's higher earnings in 2005.  The
Company currently expects its third quarter 2005 effective rate to
approximate 38 percent and its full year 2005 effective rate to be in the 37
to 38 percent range.


Comparison of six months ended June 30, 2005, to six months ended June 30,
2004
              
Revenues

     Consolidated operating revenues increased by $408 million, or 12.8
percent, primarily due to a $379 million, or 12.3 percent, increase in
passenger revenues.  The increase in passenger revenues was primarily due to
a 10.0 percent increase in revenue passenger miles (RPMs) flown.  

     Capacity for first half 2005, as measured by available seat miles
(ASMs), increased 11.9 percent compared to the first half of 2004.  The
capacity increase resulted from the net addition of 29 aircraft (net of 18
retirements) since the end of second quarter 2004.  Load factor for the first
half 2005 was 69.1 percent, a decrease of 1.2 points compared to the first
half of 2004.  The Company also experienced a 7.8 percent increase in revenue
passengers carried compared to the first half of 2004.

     Passenger yield per RPM for the first half 2005 increased 2.1 percent to
12.05 cents from 11.80 cents in the first half of 2004, primarily due to less
fare discounting during the same 2005 period.  Unit revenue (operating
revenue per ASM) increased .8 percent to 8.68 cents compared to the first
half of 2004, as the lower load factor was more than offset by the increase
in RPM yield and strong performances in both freight and other revenues.
	
     Consolidated freight revenues increased by $13 million, or 24.1 percent. 
Approximately 65 percent of the increase was due to an increase in mail
revenues, as the U.S. Postal Service shifted more business to commercial
carriers.  Other revenues increased by $16 million, or 25.0 percent, 
compared to the first half of 2004 primarily due to a 14.8 percent increase
in commissions earned from programs the Company sponsors with certain
business partners, such as the Company sponsored Chase Visa card.



Operating expenses

     To a large extent, changes in operating expenses for airlines are driven
by changes in capacity, or ASMs.  The following presents Southwest's
operating expenses per ASM for the six months ended June 30, 2005 and 2004,
followed by explanations of changes on a per-ASM basis:


                                Six months ended June 30,   Per ASM   Percent

     Operating expenses per ASM were 7.76 cents, a 2.5 percent decrease
compared to 7.96 cents for the first half of 2004.  Approximately half of the
year-over-year CASM decrease was due to 2004 costs incurred associated with
the Company's Reservations Center consolidation, voluntary early-out plan
offered to all Employees except officers, and charges associated with the
Company's labor agreement with its Flight Attendants.  Excluding these 2004
items, year-over-year CASM decreased primarily due to lower maintenance
costs, lower other operating expenses, and lower salaries, wages, and
benefits, partially offset by higher fuel and oil expense.  Excluding fuel,
CASM was 5.8 percent lower than the first half of 2004, at 6.29 cents per
ASM.

     Salaries, wages, and benefits expense per ASM decreased 3.7 percent.  In
the first half of 2004, salaries, wages, and benefits included approximately
$13 million in severance and benefits associated with the Company's
Reservations Center consolidation, $11 million of bonus pay and benefits
associated with the Company's voluntary early-out plan offered to all
Employees except officers, and approximately $7 million in pay and benefit
increases associated with the Company's labor agreement with its Flight
Attendants (an additional $5 million related to per diem increases 
was included in "Other operating expenses").  Excluding these costs,
salaries, wages, and benefits decreased approximately 1.6 percent on a per
ASM basis compared to the first half of 2004.  Higher average wage rates and
higher profitsharing expense per ASM from the increase in earnings were
mostly offset by continued productivity efforts that have enabled the Company
to reduce headcount while continuing to grow its aircraft fleet, as well as
lower benefits expense, primarily health care.

     Fuel and oil expense per ASM increased 14.8 percent primarily due to an
increase in the average jet fuel price per gallon.  The average fuel cost per


gallon in first half 2005 was 96.3 cents, 19.2 percent higher than the first
half of 2004, including the effects of hedging activities.  For first 
half 2005, the Company was hedged for 86 percent of its fuel needs, resulting
in gains recorded in fuel and oil expense of $351 million.
	
     Maintenance materials and repairs per ASM decreased 21.9 percent
primarily due to a decrease in repair events for aircraft engines.

     Aircraft rentals per ASM decreased 12.5 percent compared to the first
half of 2004.  The majority of the decrease per ASM was due to the Company's
growth occurring with purchased aircraft.  All of the aircraft acquired in
2004, except for one, and all of the aircraft acquired thus far in 2005, are
owned by the Company.  

     Landing fees and other rentals per ASM were flat compared to the first
half of 2004, as higher landing fees per ASM were offset by a decline in
other rentals per ASM.  The Company experienced a 6.0 percent increase in
landing fees per ASM, primarily due to higher rates paid.  There was a 3.9 
percent decrease in other rentals expense per ASM, primarily due to
efficiencies gained by capacity growth exceeding the expansion of gate and
counter space at airports.  	

     Depreciation expense per ASM decreased 1.8 percent primarily due to the
retirement of equipment associated with the Company's 737-200 aircraft, the
remainder of which were phased out of the Company's fleet in January 2005.  

     Other operating expenses per ASM decreased 6.2 percent compared to the
first half of 2004.  Approximately one-third of the decrease was due to lower
advertising costs, and approximately one-third was due to lower personnel
expenses.  These and other smaller decreases were partially offset by higher
fuel sales taxes due to the substantial increase in fuel prices.

	
Other

	Interest expense increased 42.5 percent compared to the first half of
2004.  The majority of the increase was due to the issuance of new debt,
including the Company's September 2004 issuance of $350 million senior
unsecured Notes, fourth quarter 2004 issuance of $112 million of French 
credit agreements, and the February 2005 issuance of $300 million senior
unsecured Notes.  These new issuances were partially offset by the November
2004 redemption of $175 million aircraft secured Notes, and the March 2005
redemption of $100 million senior unsecured Notes.  

	Capitalized interest decreased by $1 million, or 5.0 percent, primarily
due to a decrease in progress payment balances for future aircraft
deliveries.  

     Interest income increased by $8 million, or 88.9 percent, primarily due
to an increase in rates earned on cash and higher investment balances.  

     "Other (gains) losses, net" primarily includes amounts recorded in
accordance with SFAS 133.  See Note 5 to the unaudited condensed consolidated
financial statements for more information on the Company's hedging
activities.  During first half 2005, the Company recognized approximately $17


million of expense related to amounts excluded from the Company's 
measurements of hedge effectiveness and $25 million in income related to the
ineffectiveness of its hedges.  In the first half of 2004, the Company
recognized approximately $12 million of expense related to amounts excluded
from the Company's measurements of hedge effectiveness and $1 million in
income related to the ineffectiveness of its hedges. 

     The Company's effective tax rate decreased to 36.5 percent in first half
2005 from 37.0 percent in the first half of 2004.  The lower rate reflected a
first quarter 2005, $6 million ($.01 per share, diluted) reduction in income
tax expense, attributable to the favorable resolution of an industry-wide
issue regarding the tax treatment of certain aircraft engine maintenance
costs.


Liquidity and Capital Resources

     Net cash provided by operating activities was $1.55 billion for the six
months ended June 30, 2005, compared to $847 million in the same prior year
period.  The increase was primarily due to an increase in Accounts payable
and accrued liabilities, primarily from $650 million more in counterparty
deposits associated with the Company's fuel hedging program, and the increase
in net earnings versus the prior year.  See Item 3, and Notes 5 and 8 to the
unaudited condensed consolidated financial statements.  Net cash provided by
operating activities was $1.9 billion for the 12 months ended June 30, 2005. 
Cash generated from operating activities for the 12 months ended June 30,
2005, was primarily used to finance capital expenditures.

     Cash flows used in investing activities during the six months ended June
30, 2005, totaled $468 million compared to $850 million in 2004.  Investing
activities in both years consisted primarily of payments for new 737-700
aircraft delivered to the Company and progress payments for future aircraft
deliveries.  In addition, investing activities for the six months ended June
30, 2005, was reduced $257 million by a change in the balance of the
Company's of short-term investments, namely auction rate securities.  Cash
flows used in investing activities for the 12 months ended June 30, 2005 
totaled $1.5 billion.

     Net cash generated from financing activities during the six months ended
June 30, 2005, was $135 million compared to $74 million used in financing
activities in 2004.  The Company generated $300 million from the February
2005 issuance of senior unsecured Notes due 2017.  This was partially offset
by cash used to redeem the $100 million senior unsecured 8% Notes due March
1, 2005, and to repurchase $55 million of the Company's common stock. 

    In fourth quarter 2004, Southwest was selected as the winning bidder at a
bankruptcy-court approved auction for certain ATA Airlines, Inc. (ATA)
assets.  As part of the transaction, which was approved in December 2004,
Southwest provided ATA with $40 million in debtor-in-possession financing
while ATA remains in bankruptcy, and has also guaranteed the repayment of an
ATA construction loan to the City of Chicago for $7 million.  The $40 million
debtor-in-possession financing, which was set to mature September 30, 2005,
has now been extended to December 31, 2005 (coinciding with ATA's expected
emergence from bankruptcy).  This loan is classified as "Accounts and other 
receivables" in the Consolidated Balance Sheet, and the estimated fair value 


of the Company's guarantee of the ATA construction loan, which is not
material, is classified as part of "Other deferred liabilities".  The debtor-
in-possession financing bears interest at a rate equal to the higher of 8
percent or LIBOR plus 5 percent, and interest is payable to Southwest
monthly.  Upon ATA's emergence from bankruptcy, Southwest has committed to
convert the debtor-in-possession financing to a term loan, payable over five
years. 

     ATA is currently pursuing funding that would enable its emergence from
bankruptcy.  Although ATA's planned emergence has been extended to December
31, 2005, there is no assurance that ATA will exit bankruptcy protection on
this date, or that funding will be found that would enable ATA to emerge from
bankruptcy.  ATA has disclosed that, in addition to certain specific
reorganization objectives, it will need a capital infusion of $50 million to
$100 million to provide it with the liquidity necessary to continue as a
going concern through December 31, 2005.  Although, the Company's loan to ATA
is collateralized by certain specified assets, if ATA is unable to obtain
adequate funding and/or does not emerge from bankruptcy, loans made by 

Southwest to ATA may not be repaid in full, if at all.  As of June 30, 2005,
Southwest has not recorded an uncollectibility reserve for the ATA loan.


Contractual Obligations and Contingent Liabilities and Commitments

     Southwest has contractual obligations and commitments primarily for
future purchases of aircraft, payment of debt, and lease arrangements. 
Following the receipt of 22 new 737-700 aircraft from Boeing during the first
six months of 2005, the Company has 12 737-700 aircraft deliveries for the
remainder of 2005.  The Company recently exercised an option for one 737-700
aircraft to be delivered in 2006, bringing the Company's firm orders to 34
aircraft.  The following table details the Company's current (as of June 30,
2005) firm orders, options, and purchase rights through 2012.

     The Company has the option, which must be exercised two years prior to
the contractual delivery date, to substitute -600s or -800s for the -700s. 
Aggregate funding needed for firm aircraft commitments, as of June 30, 2005,
was approximately $1.6 billion, subject to adjustments for inflation, due as
follows: $384 million remaining in 2005, $716 million in 2006, $420 million
in 2007, and $80 million thereafter.
	
     The Company has various options available to meet its capital and
operating commitments, including cash on hand at June 30, 2005, of $2.3
billion, internally generated funds, and the Company's fully available $575
million revolving credit facility.  The Company will also consider various
borrowing or leasing options to maximize earnings and supplement cash
requirements.  

     During first quarter 2005, the Company issued $300 million senior
unsecured Notes (Notes) due 2017.  The Notes bear interest at 5.125 percent,
payable semi-annually in arrears, with the first payment due on September 1,
2005.  Also during first quarter 2005, the Company redeemed its $100 million
8% senior unsecured notes on the maturity date of March 1, 2005.  See Note 7
to the condensed consolidated financial statements.

     The Company currently has outstanding shelf registrations for the
issuance of up to $350 million in public debt securities and pass through
certificates, which it may utilize for aircraft financings or other purposes
in the future.  

Forward looking statements

Some statements in this Form 10-Q (or otherwise made by the Company or on the
Company's behalf from time to time in other reports, filings with the
Securities and Exchange Commission, news releases, conferences, World Wide
Web postings or otherwise) which are not historical facts may be "forward-
looking statements" within the meaning of Section 21E of the Securities 
Exchange Act of 1934 and the Private Securities Litigation Reform Act of
1995. Forward-looking statements include statements about Southwest's
estimates, expectations, beliefs, intentions, or strategies for the future,
and the assumptions underlying these forward-looking statements. Southwest
uses the words "anticipates," "believes," "estimates," "expects," "intends,"
"forecasts," "may," "will," "should," and similar expressions to identify
these forward-looking statements. Forward-looking statements involve risks
and uncertainties that could cause actual results to differ materially from
historical experience or the Company's present expectations. Factors that
could cause these differences include, but are not limited to: 

-  Items directly linked to the September 11, 2001, terrorist attacks, such
   as the adverse impact of new airline and airport security directives on
   the Company's costs and Customer demand for travel, changes in the  
   Transportation Security Administration's scope for managing U.S. airport
   security, and the possibility of further terrorist attacks or additional
   incidents that could cause the public to question the safety and/or 
   efficiency of air travel.

-  The availability and cost of war-risk and other aviation insurance,
   including the federal government's provision of third party war-risk 
   coverage to airlines.  The government's coverage currently extends to 
   August 31, 2005, and the Company expects the Department of Transportation
   will extend it further to December 31, 2005.  However, there are no
   assurances that such coverage will be extended beyond August 31, 2005 or
   December 31, 2005.  

-  War or other military actions by the U.S. or others.

-  Competitive factors, such as fare sales and capacity decisions, changes in
   competitors' flight schedules, mergers and acquisitions, codesharing
   programs, and airline bankruptcies.

-  General economic conditions, which could adversely affect the demand for
   travel in general and consumer ticket purchasing habits, as well as
   decisions by major freight Customers on how they allocate freight
   
   deliveries among different types of carriers.

-  Factors that could affect the Company's ability to control its costs, such
   as the results of Employee labor contract negotiations, Employee hiring
   and retention rates, costs for health care, capacity decisions by the
   Company and its competitors, unscheduled required aircraft airframe or
   engine repairs and regulatory requirements, changes in commission policy, 
   availability of capital markets, and future financing decisions made by
   the Company.

-  Factors affecting the Company's fuel expense, including, but not limited
   to, the largely unpredictable prices of jet fuel, crude oil, heating oil,
   and unleaded gasoline, the continued effectiveness of the Company's fuel
   hedges, changes in the Company's overall fuel hedging strategy, and the
   continued ability of commodities used in fuel hedging to qualify for
   special hedge accounting.
 
-  Disruptions to operations due to adverse weather conditions and air
   traffic control-related constraints.

-  Internal failures of technology or large-scale external interruptions in
   technology infrastructure, such as power, telecommunications, or the
   internet. 

-  Risks involved with the Company's acquisition of certain assets from ATA
   Airlines, Inc. (ATA), including the collectibility of loans made to ATA,
   and the continued success of the Company's codeshare agreement with ATA.

Caution should be taken not to place undue reliance on the Company's forward-
looking statements, which represent the Company's views only as of the date
this report is filed. The Company undertakes no obligation to update publicly
or revise any forward-looking statement, whether as a result of new
information, future events or otherwise.  





Item 3.  Quantitative and Qualitative Disclosures About Market Risk

As discussed in Note 5 to the unaudited condensed consolidated financial
statements, the Company utilizes financial derivative instruments to hedge
its exposure to material increases in jet fuel prices.  During the first six
months of 2005, because of the continued upward trend in energy prices, the
fair values of the Company's fuel hedge contracts have increased
significantly.  At June 30, 2005, the estimated gross fair value of
outstanding contracts was $1.8 billion, compared to $796 million at December
31, 2004.  

Outstanding financial derivative instruments expose the Company to credit
loss in the event of nonperformance by the counterparties to the agreements. 
However, the Company does not expect any of the counterparties to fail to
meet their obligations.  The credit exposure related to these financial
instruments is represented by the fair value of contracts with a positive
fair value at the reporting date.  To manage credit risk, the Company selects
and periodically reviews counterparties based on credit ratings, limits its
exposure to a single counterparty, and monitors the market position of the
program and its relative market position with each counterparty. At June 30,
2005, the Company had agreements with seven counterparties containing early
termination rights and/or bilateral collateral provisions whereby security is
required if market risk exposure exceeds a specified threshold amount or
credit ratings fall below certain levels.  At June 30, 2005, the Company held
$980 million in fuel hedge related cash collateral deposits and $150 million
in U.S. Treasury Bills, under these bilateral collateral provisions.  These
collateral deposits serve to decrease, but not totally eliminate, the credit
risk associated with the Company's hedging program. The cash deposits, which
can have a significant impact on the Company's cash balance and cash flows as
of and for a particular operating period, are included in "Accrued
liabilities" on the Consolidated Balance Sheet and are included as "Operating
cash flows" in the Consolidated Statement of Cash Flows.  In accordance with
SFAS 140, "Accounting for Transfers and Servicing of Financial Assets and
Extinguishments of Liabilities", the U.S. Treasury Bills, supplied as non-
cash collateral by counterparties, are not reflected on the Company's
Consolidated Balance Sheet.  See also Note 8 to the unaudited condensed
consolidated financial statements.  

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, 2004
and Note 5 to the unaudited condensed consolidated financial statements for
further information about Market Risk.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures designed to ensure
that it is able to collect the information it is required to disclose in the
reports it files with the Securities and Exchange Commission (SEC), and to
process, summarize and disclose this information within the time periods
specified in the rules of the SEC. Based on an evaluation of the Company's
disclosure controls and procedures as of the end of the period covered by
this report conducted by the Company's management, with the participation of 
the Chief Executive and Chief Financial Officers, the Chief Executive and 


Chief Financial Officers believe that these controls and procedures are
effective to ensure that the Company is able to collect, process, and
disclose the information it is required to disclose in the reports it files
with the SEC within the required time periods.



PART II. OTHER INFORMATION

Item 1.     Legal Proceedings

The Company is subject to various legal proceedings and claims arising in the
ordinary course of business, including, but not limited to, examinations by
the Internal Revenue Service (IRS).  The IRS regularly examines the Company's
federal income tax returns and, in the course thereof, proposes adjustments
to the Company's federal income tax liability reported on such returns.  It
is the Company's practice to vigorously contest those proposed adjustments it
deems lacking of merit.  

The Company's management does not expect that the outcome in any of its
currently ongoing legal proceedings or the outcome of any proposed
adjustments presented to date by the IRS, individually or collectively, will
have a material adverse effect on the Company's financial condition, results
of operations or cash flow.
