ITEM 1. BUSINESS

DESCRIPTION OF BUSINESS

     Southwest Airlines Co. (Southwest) is a major domestic airline that
provides shorthaul, high frequency, point-to-point, low fare service.  Southwest
was incorporated in Texas and commenced Customer Service on June 18, 1971 with
three Boeing 737 aircraft serving three Texas cities - Dallas, Houston, and San
Antonio.
 
     At yearend 1994, Southwest operated 199 Boeing 737 aircraft and provided
service to 45 airports in 44 cities primarily in the midwestern, southwestern,
and western regions of the United States.

     On December 31, 1993, Southwest acquired Morris Air Corporation (Morris) in
a stock-for-stock exchange, issuing approximately 3.6 million shares of
Southwest Common Stock in exchange for all of the outstanding shares of Morris.
During 1994, the operations of Morris were substantially integrated with those
of Southwest.  As a result of that process, Southwest commenced service to seven
new cities in 1994:  Tucson, Arizona; Santa Ana (Orange County), California;
Boise, Idaho; Portland, Oregon; Salt Lake City, Utah; Seattle, and Spokane,
Washington.  Unless the context requires otherwise, references in this annual
report to the "Company" include Southwest and Morris.

     The business of the Company is somewhat seasonal.  Quarterly operating
income and, to a lesser extent, revenues tend to be somewhat lower in the first
quarter (January 1 - March 31).

FUEL

     The cost of fuel is an item having significant impact on the Company's
operating results.  The Company's average cost of jet fuel per gallon for
scheduled carrier service over the past five years was as follows:

<TABLE>
                             <S>              <C>
                             1990             $.78
                             1991             $.66
                             1992             $.61
                             1993             $.59
                             1994             $.54
</TABLE>

     The Company is unable to predict the extent of future fuel cost changes.
The Company has standard industry arrangements with major fuel suppliers.
Standard industry fuel contracts do not provide material protection against
price increases or for assured availability of supplies.  The Company uses
various price-risk management techniques, including derivative products such as
fixed-price swaps, caps, and collars, to help protect against price increases.
To date, not more than 11 percent of then-current usage was hedged in this
manner.  Although market conditions can significantly impact the price of jet
fuel, at present, these conditions have not resulted in an inadequate supply of
jet fuel.  For more discussion of current jet fuel costs and the impact of these
costs on the Company's operations, see Management's Discussion and Analysis of
Financial Condition and Results of Operations.

                                       1

REGULATION

     Economic.  The Dallas Love Field section of the International Air
Transportation Competition Act of 1979 (Competition Act), as it affects
Southwest's scheduled service, provides that no common carrier may provide
scheduled passenger air transportation for compensation between Love Field and
one or more points outside Texas, except that an air carrier may transport
individuals by air on a flight between Love Field and one or more points within
the states of Arkansas, Louisiana, New Mexico, Oklahoma, and Texas if (a) "such
air carrier does not offer or provide any through service or ticketing with
another air carrier" and (b) "such air carrier does not offer for sale
transportation to or from, and the flight or aircraft does not serve, any point
which is outside any such states."   Southwest does not interline or offer joint
fares with any other air carrier.  The Competition Act does not restrict
Southwest's intrastate Texas flights or its air service from points other than
Love Field to points beyond Texas and the four contiguous states.

     The Department of Transportation (DOT) has significant regulatory
jurisdiction over passenger airlines.  Unless exempted, no air carrier may
furnish air transportation over any route without a DOT certificate of
authorization, which does not confer either exclusive or proprietary rights.
The Company's certificates are unlimited in duration and permit the Company to
operate among any points within the United States, its territories and
possessions, except as limited by the Love Field section of the Competition Act,
as do the certificates of all other U.S. carriers.  DOT may revoke such
certificates, in whole or in part, for intentional failure to comply with any
provisions of subchapter IV of the Federal Aviation Act of 1958, or any order,
rule or regulation issued thereunder or any term, condition or limitation of
such certificate; provided that, with respect to revocation, the certificate
holder has first been advised of the alleged violation and has been given a
reasonable time to effect compliance.

     DOT prescribes uniform disclosure standards regarding terms and conditions
of carriage, and prescribes that terms incorporated into the Contract of
Carriage by reference are not binding upon passengers unless notice is given in
accordance with its regulations.

     Safety.  The Company is subject to the jurisdiction of the Federal Aviation
Administration (FAA) with respect to its aircraft maintenance and operations,
including equipment, ground facilities, dispatch, communications, flight
training personnel, and other matters affecting air safety.  To ensure
compliance with its regulations, the FAA requires airlines to obtain operating,
airworthiness and other certificates which are subject to suspension or
revocation for cause.  The Company has obtained such certificates.  The FAA,
acting through its own powers or through the appropriate U. S. Attorney, also
has the power to bring proceedings for the imposition and collection of fines
for violation of the Federal Air Regulations.

     Environmental.  The Airport Noise and Capacity Act of 1990 (ANCA) requires
the phase out of Stage 2 airplanes (which meet less stringent noise emission
standards than later model Stage 3 airplanes) in the contiguous 48 states by
December 31, 1999.   FAA rules establish interim compliance dates for ANCA of
December 31, 1994, December 31, 1996, and December 31, 1998.  An operator may
comply by either implementing a reduction of the operator's base level, as
defined in ANCA, of Stage 2 aircraft by at least 25 percent increments by the
end of the three interim compliance dates or by operating a fleet that is at
least 55 percent Stage 3 by December 31, 1994, 65 percent by December 31, 1996,
and 75 percent by December 31, 1998.  Selection of one of the two alternative
compliance techniques is not irrevocable and operators are free to opt for one
method at one compliance date and another at the next.  Operation of Stage 2
aircraft after December 31, 1999 is prohibited, subject, however, to an
extension of the final compliance date to December 31, 2003, if at least 85
percent of the aircraft used by the operator in the contiguous United States
will comply with Stage 3 noise levels by July 1, 1999 and the operator
successfully obtains a waiver from the FAA of the December 31, 1999 final
phaseout date.  Statutory requirements to obtain a waiver include a
determination by the FAA that the waiver is in the

                                       2
<PAGE>
 
public interest or would enhance competition or benefit service to small
communities.  There is no assurance that such a waiver is obtainable.

     The Company's fleet, as of December 31, 1994, consisted of 50 Stage 2
aircraft and 149 Stage 3 aircraft, yielding a Stage 3 percentage of 74.9
percent.  Accordingly, the Company exceeds the Stage 3 fleet percentage
requirement for the December 31, 1994 and December 31, 1996 interim compliance
dates.

     As of December 31, 1994, of the 50 Stage 2 aircraft operated by the
Company, 30 are leased from third parties and 20 are owned by the Company.  The
Company can comply with the rules by acquiring additional Stage 3 aircraft,
returning Stage 2 aircraft to the lessors as the leases terminate according to
their terms, retiring owned Stage 2 aircraft, or hushkitting Stage 2 aircraft.
Because the Company already complies with the December 31, 1998 interim
compliance requirement of a 75 percent Stage 3 fleet, the Company could operate
all 50 of its Stage 2 aircraft until December 31, 1999.  Based upon the
Company's current schedule for delivery of new Stage 3 aircraft, including
options, the Company could achieve 85 percent compliance by July 1, 1999 through
the retirement of only seven of the 50 Stage 2 aircraft, assuming no
hushkitting.  This would qualify the Company to apply for a waiver from the
final compliance date, which, if obtained, could permit the Company to continue
operation of the remaining 43 Stage 2 aircraft until, at the latest, December
31, 2003.

     ANCA also requires the FAA to establish parameters within which any new
Stage 2 and Stage 3 noise or access restrictions at individual airports must be
developed.  The published rules generally provide that local noise restrictions
on Stage 3 aircraft first effective after October 1990 require FAA approval, and
establish a regulatory notice and review process for local restrictions on Stage
2 aircraft first proposed after October 1990.  Certain airports, including
Dallas Love Field, Los Angeles, San Diego, San Francisco, and Orange County,
have established airport restrictions to limit noise, including restrictions on
aircraft types to be used and limits on the number of hourly or daily operations
or the time of such operations.  In some instances, these restrictions have
caused curtailments in service or increases in operating costs and such
restrictions could limit the ability of Southwest to expand its operations at
the affected airports.  Local authorities at other airports are considering
adopting similar noise regulations.

     Operations at John Wayne Airport, Orange County, California, are governed
by the Airport's Phase 2 Commercial Airline Access Plan and Regulation (the
"Plan").  Pursuant to the Plan, each airline is allocated total annual seat
capacity to be operated at the airport, subject to renewal/reallocation on an
annual basis.  The airport's governing body completed the reallocation process
on February 7, 1995.  The Company was allocated seat capacity to operate only 14
daily flights, rather than the 21 flights being operated as of January 15, 1995,
thereby necessitating a reduction of seven daily flights by the Company.  To
comply with the Plan, the Company will maintain seven daily flights to San Jose
and Oakland, California, respectively, and will eliminate non-stop service to
Salt Lake City, Utah (two daily flights) and Phoenix, Arizona (four daily
flights) and one daily flight to San Jose, all effective April 1, 1995.

     The Company is subject to various other federal, state, and local laws and
regulations relating to the protection of the environment, including the
discharge of materials into the environment.

MARKETING AND COMPETITION

     Southwest focuses on point-to-point, rather than hub-and-spoke, service in
shorthaul markets with frequent, conveniently timed flights, and low fares.  For
example, Southwest's average aircraft trip length in 1994 was 391 miles with an
average duration of approximately one hour.  At yearend, Southwest served 298
nonstop city pairs with an average weekday frequency of six roundtrips per city
pair.

                                       3
<PAGE>
 
     Southwest's point-to-point route system, as compared to hub-and-spoke,
provides for more direct nonstop routings for shorthaul customers and,
therefore, minimizes connections, delays, and total trip time.  Southwest
focuses on local, not connecting, traffic.  As a result, approximately 80
percent of the Company's customers fly nonstop. In addition, Southwest serves
many conveniently-located satellite or downtown airports such as Dallas Love
Field, Houston Hobby, Chicago Midway, Baltimore, Burbank, Oakland, and San Jose
airports, which are typically less congested than other airlines' hub airports
and enhance the Company's ability to sustain high employee productivity and
reliable ontime performance.  This operating strategy also permits the Company
to achieve high asset utilization.  Aircraft are scheduled to minimize the
amount of time the aircraft is at the gate, approximately 20 minutes, thereby
reducing the number of aircraft and gate facilities that would otherwise be
required.  Southwest does not interline with other jet airlines, nor have any
commuter feeder relationships.

     Southwest employs a very simple fare structure, maintaining low,
unrestricted, unlimited everyday coach fares.  The Company operates only one
aircraft type, the Boeing 737, which simplifies scheduling, maintenance, flight
operations, and training activities.

     In May 1994, the computer reservations systems (CRSs) used by travel
agencies owned by United Airlines (Apollo) and Continental Airlines (System One)
disabled automated ticketing for Southwest travel.  Rather than pay the fees
associated with CRS participation in Apollo and System One, Southwest has taken
the following actions:  Southwest has provided direct access to its own
reservation system and ticketing for the 50 largest travel agencies (SWAT);
instituted overnight delivery of Southwest-produced tickets for approximately
300 large travel agencies; improved access to Ticket By Mail for direct
Customers by reducing the time limit from seven days out from the date of travel
to three days; and introduced a Ticketless travel option, eliminating the need
to print a paper ticket altogether.  Southwest has also entered into a new
arrangement with SABRE, the CRS in which Southwest has historically participated
to a limited extent, providing for ticketing and automated booking on Southwest
in a very cost-effective manner.

     The airline industry is highly competitive as to fares, frequent flyer
benefits, routes, and service, and some carriers competing with the Company have
greater financial resources, larger fleets, and wider name recognition.  Several
of the Company's larger competitors have initiated low-cost, shorthaul service
in markets served by the Company, which represents a more direct threat in
Southwest's market niche. Profit levels in the air transport industry are highly
sensitive to changes in operating and capital costs and the extent to which
competitors match an airline's fares and services.  The profitability of a
carrier in the airline industry is also impacted by general economic trends.
For more discussion on the current competitive environment for Southwest, see
Management's Discussion and Analysis of Financial Condition and Results of
Operations.

     The Company is also subject to varying degrees of competition from surface
transportation in its shorthaul markets, particularly the private automobile.
In shorthaul air services which compete with surface transportation, price is a
competitive factor, but frequency and convenience of scheduling, facilities,
transportation safety, and Customer Service may be of equal or greater
importance to many passengers.

INSURANCE

     The Company carries insurance of types customary in the airline industry
and in amounts deemed adequate to protect the Company and its property and to
comply both with federal regulations and certain of the Company's credit and
lease agreements.  The policies principally provide coverage for public and
passenger liability, property damage, cargo and baggage liability, loss or
damage to aircraft, engines, and spare parts, and workers' compensation.

                                       4
<PAGE>
 
FREQUENT FLYER AWARDS

     Southwest's frequent flyer program, The Company Club, is based on trips
flown rather than mileage.  The Company Club offers one free roundtrip travel
award to any Southwest destination after flying eight roundtrips (or 16 one-way
trips) on Southwest within a consecutive twelve-month period.

     The trips flown as credit towards a free travel award certificate are valid
for twelve months only; the free travel award is automatically generated when
earned by the Customer rather than allowing the Customer to bank the trip
credits indefinitely; and the free travel award is valid for one year with an
automatic expiration date.  Based on the issuance of free travel awards to
qualified members, coupled with the foregoing program characteristics and the
use of "black out" dates for the free travel awards during peak holiday periods,
the financial impact of free travel awards used on the Company's consolidated
financial statements has not been material.  Free travel awards redeemed were
approximately 279,000,  256,000, and 209,000 during 1994, 1993, and 1992,
respectively.  The amount of free travel award usage as a percentage of total
Southwest revenue passengers carried was 1.4 percent in 1994 and 1.5 percent in
both 1993 and 1992.

     The Company accounts for free travel awards using the incremental cost
method, consistent with the other major airlines.  This method recognizes an
average incremental cost to provide roundtrip transportation to one additional
passenger.  The incremental cost to provide free transportation is accrued at
the time an award is earned and revenue is subsequently recognized, at the
amount accrued, when the free travel award is used.  The estimated incremental
costs include passenger costs such as beverage and snack supplies, baggage
claims, baggage handling, and liability insurance; operations costs such as
security services, airport rentals, fuel, oil, and into-plane charges; and
reservations costs, such as communications and system operations fees.  The
liability for free travel awards earned but not used at December 31, 1994 and
1993 was not material.

     The number of free travel awards for Southwest outstanding at December 31,
1994 and 1993 was approximately 248,000 and 178,000, respectively.  These
numbers do not include partially earned awards.  The Company currently does not
have a system to accurately estimate partially earned awards.  However, these
partially earned awards may equate to approximately 60-70 percent of the current
outstanding awards.  Since the inception of The Company Club in 1987,
approximately 15 percent of all award certificates have expired without being
used.

EMPLOYEES

     At December 31, 1994, Southwest (including Morris) had 16,818 employees,
consisting of 4,894 flight, 747 maintenance, 9,237 ground customer service and
1,940 management, accounting, marketing, and clerical personnel.

     Southwest has nine collective bargaining agreements covering approximately
83 percent of its employees.  Southwest's fleet service employees are subject to
an agreement with the Ramp, Operations and Provisioning Association, which
became amendable in December 1994 and is currently in negotiation.  Customer
service and reservation employees are subject to an agreement with the
International Association of Machinists and Aerospace Workers, AFL-CIO (IAM),
which becomes amendable in November 1997.  Flight attendants are subject to an
agreement with the Transportation Workers Union of America, AFL-CIO, which
becomes amendable May 31, 1996.  The pilots are subject to an agreement with the
Southwest Airlines Pilots' Association (SWAPA), which becomes amendable in
September 1999 (described below).  Flight dispatchers are represented by the
Southwest Airlines Employees Association, pursuant to an agreement which becomes
amendable in November 1997.  Mechanics, aircraft cleaners

                                       5
<PAGE>
 
and stock clerks are subject to agreements with the International Brotherhood of
Teamsters, with both agreements becoming amendable in August 1995.  The flight
simulator technicians are represented by the International Brotherhood of
Teamsters pursuant to an agreement which becomes amendable in October 1995.  The
flight/ground school instructors are subject to an agreement with the Southwest
Airlines Professional Instructors Association which becomes amendable in
December 1995.

     The Company recently entered into two labor contracts with large employee
groups.  In November 1994, Southwest entered into an agreement with the IAM
covering Customer service and reservation employees.  In January 1995,
Southwest's pilots ratified a ten-year labor contract that calls for no wage
increases in the first five years and three percent annual wage increases in
three of the last five years of the contract.  Initially, the pilots will
receive options to purchase approximately 14.5 million shares of Southwest
common stock at $20 per share over the term of the contract; pilots hired
subsequently will receive additional grants at a five percent premium over then
current fair market value, up to a total of 18,000,000 shares that can be issued
under the stock option plan.  Pilots will be eligible for profitability bonuses
of up to three percent of compensation in three of the first five years and
profitability-based pay increases up to three percent in two of the second five
years of the contract.  The pilot group may choose to reopen the contract in
five years, in which event all unexercised options will terminate.

ITEM 2. PROPERTIES

AIRCRAFT

     Southwest and Morris operated a total of 199 Boeing 737 aircraft as of
December 31, 1994, of which 89 and 13 were under operating and capital leases,
respectively.  The remaining 97 aircraft are owned.

     In January 1994, Southwest entered into an agreement with The Boeing
Company, pursuant to which Southwest is the launch customer for the Boeing 737-
700 aircraft, the newest generation of the Boeing 737 aircraft type.  As the
launch customer, Southwest has agreed to purchase sixty-three Boeing 737-700
aircraft from 1997 to 2001, with options for an additional 63 737-700 aircraft
from 1998 to 2004.  As a part of this transaction, 42 of the 53 options for 737-
300 aircraft from 1997 to 1999 were canceled.

     In total, including an agreement in principle to lease two used aircraft in
second quarter 1995, at December 31, 1994, the Company had 118 firm orders and
74 options as follows:

    The Company has an agreement with CFM International, Inc. (a joint company
of SNECMA (France) and General Electric Company) dated May 28, 1981, as amended,
for the supply of spare engines for its Boeing 737-300, -500, and -700 aircraft.
CFM also supplies the engines to The Boeing Company for original installation on
such aircraft.  CFM is the sole manufacturer of engines for use on the Boeing
737-300, -400, -500, and -700 aircraft.

GROUND FACILITIES AND SERVICES

    Southwest leases terminal passenger service facilities at each of the
airports it serves to which it has added various leasehold improvements.  The
Company leases land on a long-term basis for its maintenance centers located at
Dallas Love Field, Houston Hobby, and Phoenix Sky Harbor, its training center
near Love Field which houses three 737 simulators, and its corporate
headquarters also located near Love Field.  The maintenance, training center,
and corporate headquarters buildings on these sites were built and are owned by
Southwest.  At December 31, 1994, the Company operated seven reservation
centers.  The reservation centers located in Chicago, Illinois; Albuquerque, New
Mexico; and Salt Lake City, Utah occupy leased space.  The Company owns its
Dallas, Texas; Houston, Texas; Phoenix, Arizona; and San Antonio, Texas
reservation centers.  In January 1995, the Company opened its newest reservation
center in Little Rock, Arkansas on leased land and has announced an intention to
locate an additional reservation center on leased land in Oklahoma City,
Oklahoma.

    The Company performs substantially all line maintenance on its aircraft and
provides ground support services at most of the airports it serves.  However,
the Company has arrangements with certain aircraft maintenance firms for major
component overhauls and repairs for its airframes and engines, which comprise
the majority of the annual maintenance cost.

    In recent years, many airports have increased or sought to increase the
rates charged to airlines.  The extent to which such charges are limited by
statute and the ability of airlines to contest such charges has been subject to
litigation, including a case recently decided against certain carriers by the
United States Supreme Court.  To the extent the limitations on such charges are
relaxed or the ability of airlines to challenge such charges is restricted, the
rates charged by airports to airlines may increase substantially.  Management
cannot predict the magnitude of any such increase.

ITEM 3.  LEGAL PROCEEDINGS

    In January 1994, Southwest received an examination report from the Internal
Revenue Service proposing certain adjustments to Southwest's income tax returns
for 1987 and 1988.  The adjustments relate to certain types of aircraft
financings consummated by Southwest, as well as other members of the aviation
industry, during that time period.  Southwest intends to vigorously protest the
adjustments made with which it does not agree.  The industry's differences with
the IRS involve complex issues of law and fact which are likely to take a
substantial period of time to resolve.  Management believes that final
resolution of such protest will not have a materially adverse effect upon the
results of operations of Southwest.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

    None to be reported.

reported in Southwest's Form 10-Q's filed in respect of the 1993 periods shown
below.  These differences are solely due to Southwest's acquisition of Morris,
which was accounted for as a pooling of interests.  See Note 2 to the
Consolidated Financial Statements.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

INDUSTRY CONDITIONS

The 1990s have been devastating financially for the domestic passenger airline
industry, with Southwest as the sole exception among larger carriers. Since
1990, the industry has been shrinking and we have been expanding. We are now
carrying more than twice the number of passengers annually than in 1990, an
annualized growth rate of 21 percent. In 1993, with the advent of Continental
Lite and plans laid for the United Shuttle, the competitive trend away from
Southwest began to reverse. In 1994, in the face of our own aggressive
expansion, we experienced a massive increase of new competitive service from
United, Continental, Reno, and TWA. We also were negatively impacted by the
industry's use of persistent fare sales during the fourth quarter, which
occurred at a time when we were aggressively converting Morris Air Corporation
(Morris) to Southwest's operations and were experiencing operating difficulties
of our own in reservations and revenue management. The result was a 47 percent
decline in earnings in fourth quarter 1994 as compared to fourth quarter 1993.
Many of the operational issues that surfaced during fourth quarter 1994 have
been, or will soon be, addressed, most notably reservations capacity. However,
some of their effects will carry over into the first two quarters of 1995, and,
further, we cannot predict the actions of our competitors.

In response to these increasing competitive pressures, we implemented several
measures.  However, we face significantly more competition than we did a year
ago, which may also continue to adversely affect comparisons to 1994 quarterly
performances, particularly in first half 1995.

As compared to year ago levels, load factors and passenger revenue yields are
currently down (the consolidated load factor for January 1995 was 57.8 percent,
compared with 63.1 percent for the same month a year ago).  Our expectation is
that this trend will continue at least during first half 1995.  As expected, the
integration of Morris into Southwest during 1994, which included 21 aircraft and
seven new cities, resulted in our immediate competitive presence in the
northwestern region of the U.S. and Salt Lake City.  However, these new markets,
which are in the development stage and, therefore, understandably low-yielding,
will need to improve for overall yields to compare favorably to year ago levels.
While there is no way to predict precisely how fast these markets will develop,
we are encouraged by the pace thus far. We have also been encouraged with
Customer acceptance of recent price increases, which may improve yield
comparisons.

From an operating cost perspective, we have been pleased with recent favorable
trends versus year ago levels, including fuel prices.  Our goal is to continue
this trend in 1995, despite our basic lack of control over fuel prices.
Significant cost reduction opportunities lie in distribution costs.  Ticketless
travel, the new SABRE Basic Booking Request, our enhanced Ticket By Mail
product, and expanded reservations operations should all combine to help reduce
distribution costs. During 1995, we currently plan to add twenty-seven 737-300
aircraft to our fleet and one new city, Omaha, Nebraska, to our route system,
which will allow us to focus on strengthening our existing route system.


RESULTS OF OPERATIONS

1994 COMPARED WITH 1993  The Company's consolidated net income for 1994 was
$179.3 million ($1.22 per share), as compared to the corresponding 1993 amount
(before the cumulative effect of accounting changes) of $154.3 million ($1.05
per share), an increase of 16.2 percent.  The increase in earnings was primarily
attributable to an increase in operating income of 8.5 percent and a decrease in
other expenses (nonoperating) of 46.9 percent.

Operating Revenues  Consolidated operating revenues increased by 12.9 percent in
1994 to $2,591.9 million, compared to $2,296.7 million for 1993.  This increase
in 1994 operating revenues was derived from a 12.7 percent increase in passenger
revenues.  Revenue passenger miles (RPMs) increased 14.8 percent in 1994,
compared to a 16.8 percent increase in available seat miles (ASMs), resulting in
a decrease in load factor from 68.4 percent in 1993 to 67.3 percent in 1994.
The 1994 ASM growth resulted from the addition of 21 aircraft during 1994.

Freight revenues in 1994 were $54.4 million, compared to $42.9 million in 1993.
The 26.9 percent increase in freight revenues exceeded the 16.8 percent increase
in ASMs for the same period primarily due to increased air freight volumes and
United States mail services.

Operating Expenses  Consolidated operating expenses for 1994 were $2,275.2
million, compared to $2,004.7 million in 1993, an increase of 13.5 percent,
compared to the 16.8 percent increase in ASMs. On a per-ASM basis, operating
expenses (excluding 1993 merger expenses) decreased 2.3 percent in 1994.  The
primary factors contributing to this decrease were an 8.8 percent decrease in
average jet fuel cost per gallon and lower agency commission costs, offset by
increased aircraft rentals.

</TABLE>

Salaries, wages, and benefits per ASM increased only .5 percent in 1994.  This
increase resulted from a 3.0 percent increase in  average salary and benefits
cost per Employee, partially offset by slower average headcount growth, which
increased only 13.8 percent in 1994 versus the 1994 capacity (ASM) increase of
16.8 percent.  The majority of the increase in average salary and benefits cost
related to increased health benefits and workers' compensation costs.  Employee
productivity improved from 2,633 passengers handled per Employee in 1993 to
2,676 in 1994.

Profitsharing and Employee savings plan expenses per ASM increased 4.8 percent
in 1994.  The increase is primarily the result of increased matching
contributions to Employee savings plans resulting from increased Employee
participation and higher matching rates in 1994 for Flight Attendants and
Customer Service Employees under their respective collective bargaining
agreements.

Fuel and oil expenses per ASM decreased 9.9 percent in 1994, primarily due to an
8.8 percent reduction in the average jet fuel cost per gallon from 1993. Jet
fuel prices remained relatively stable throughout 1994, with quarterly averages
ranging from 

                                      F-4

<PAGE>
 
$0.51 to $0.56 per gallon. Since year-end, fuel prices have averaged
approximately $0.54 per gallon.

In August 1993, the Revenue Reconciliation Act of 1993 was enacted, which, among
other things, included an increase of 4.3 cents per gallon in transportation
fuel tax, which becomes effective September 30, 1995, for jet fuel used in
commercial aviation.  This additional fuel tax will increase fuel expenses
approximately $7.5 million in fourth quarter 1995.

Maintenance materials and repairs per ASM was unchanged in 1994 compared to
1993.

Agency commissions per ASM decreased 11.3 percent due to a lower mix of travel
agency sales and lower 1994 passenger revenue per ASM.  The lower travel agency
sales mix resulted from 1994 enhancements to Southwest's ticket delivery systems
for direct Customers, as described below.

In response to actions taken by our competitor-owned reservations systems, we
reduced our operating costs and enhanced our ticket delivery systems by
developing our own Southwest Airlines Air Travel ("SWAT") system allowing high-
volume travel agents direct access to reservations; introduced overnight ticket
delivery for travel agents; reduced to three the number of advance days
reservations required for overnight delivery of tickets to customers (Ticket By
Mail); developed our own Ticketless system, which was rolled out system-wide on
January 31, 1995; and subscribed to a new level of service with SABRE that will
automate the booking process for SABRE travel agencies effective May 1, 1995.
We also continue to actively pursue other cost-effective solutions for
automating non-SABRE travel agency bookings.

Aircraft rentals per ASM increased 7.7 percent in 1994.  The increase primarily
resulted from a third quarter 1994 sale/leaseback transaction involving ten new
737-300 aircraft and a lease of three used aircraft under long-term operating
leases. At December 31, 1994, 44.7 percent of the Company's fleet was subject to
operating leases, compared to 43.3 percent at December 31, 1993.

Other operating expenses per ASM decreased 2.2 percent in 1994 compared to 1993.
The overall decrease is primarily attributable to operating efficiencies
resulting from the transition of Morris operational functions to Southwest,
primarily contract services which decreased $8.8 million (24.4 percent per ASM),
offset by an increase in advertising costs of $24.1 million (22.9 percent per
ASM) primarily associated with the start-up of seven new cities and new
competitive pressures in 1994.

                                      F-5

<PAGE>
 
Other "Other expenses (income)" included interest expense, interest income, and
nonoperating gains and losses.  Interest expense decreased $5.1 million in 1994
due to the March 1, 1993 redemption of $100 million senior unsecured notes due
1996 and the repayment of approximately $54.0 million of Morris long-term debt
during first quarter 1994.  Capitalized interest increased $8.6 million in 1994
as a result of higher levels of advance payments on aircraft compared to 1993.
Interest income for 1994 decreased $1.9 million primarily due to lower cash
balances available for short-term investment.

Income Taxes  The provision for income taxes decreased in 1994 as a percentage
of income before taxes, including cumulative effect of accounting changes, to
40.1 percent from 40.6 percent in 1993.  The 1993 rate was higher due to
deferred tax adjustments in 1993 related to the 1993 increase in the federal
corporate income tax rate from 34 percent to 35 percent(see Note 11 to the
Consolidated Financial Statements).  This was offset by increased 1994 effective
state income tax rates.

1993 COMPARED WITH 1992  Prior to 1993, Morris operated as a charter carrier.
In 1993, Morris began operating as a FAR 121 Certificated Air Carrier, or
scheduled service carrier, consistent with Southwest.  For comparability from
1993 to 1992, the statistical and operating data for 1992 are based on scheduled
passenger service only (i.e., Southwest).  Accordingly, RPMs and ASMs for 1992
relate only to scheduled carrier operations.

The Company's consolidated income for the year 1993 was $154.3 million ($1.05
per share), before the cumulative effect of accounting changes, compared to pro
forma consolidated income of $97.4 million ($.68 per share) for 1992, an
increase of 58.4 percent. The increase in earnings was primarily attributable to
an increase in operating income of 50.7 percent and was achieved despite an
increase in the federal income tax rate, which increased the provision for
income taxes $6.5 million, or $.04 per share.

Operating Revenues    Consolidated operating revenues increased by 27.4 percent
in 1993 to  $2,296.7 million.  Operating revenue per ASM for scheduled service
carrier operations increased in 1993 to $.0835 from $.0789 in 1992.  The
increase in consolidated operating revenues was primarily related to a 36.5
percent increase in passenger revenues, which accounted for 96.5 percent of
total operating revenues in 1993 versus 90.1 percent in 1992.

Consolidated RPMs increased 36.6 percent in 1993, which exceeded
the 28.8 percent increase in ASMs, resulting in an increase in the
load factor from 64.5 percent to 68.4 percent. The 1993 ASM

                                      F-6

<PAGE>
 
increase resulted from the conversion of the Morris system from charter to
scheduled service and the addition of 16 aircraft to the Southwest fleet.  The
additional 16 Southwest aircraft were primarily used to expand California, St.
Louis, and Chicago markets and to initiate service from Louisville, Baltimore,
and San Jose.

Freight revenues increased in 1993 to $42.9 million from $33.1 million in 1992.
The 29.6 percent increase in freight revenues exceeded the 28.8 percent ASM
increase primarily due to further expansion of United States mail services and
increased freight marketing programs.

Charter and other revenues decreased in 1993 from 1992 on a consolidated basis
as Morris converted its operations in 1993 to scheduled service from charter
operations. In 1993, consistent with the beginning of scheduled carrier service,
Morris revenues were primarily derived from scheduled operations and,
accordingly, classified as "passenger" revenues. Morris charter revenues totaled
$117.8 million in 1992.

Operating Expenses    Consolidated operating expenses increased 24.6 percent to
$2,004.7 million from $1,609.2 million in 1992. The primary factors contributing
to the increase were the 28.8 percent increase in ASMs; increased contributions
to profitsharing and Employee savings plans; higher agency commissions; higher
aircraft rentals; and increased maintenance costs.

On a consolidated basis, the Company incurred $10.8 million of one-time merger
expenses in connection with the December 1993 Morris acquisition. These expenses
included $1.9 million of various professional fees; $4.7 million for disposal of
duplicate or incompatible property and equipment; and $4.2 million for Employee
relocation and severance costs related to elimination of duplicate or
incompatible operations. As required for financial reporting purposes, these
expenses have been reported as operating expenses.

Salaries, wages, and benefits per ASM decreased 2.3 percent in 1993. Excluding
the effects of Morris, Southwest's cost per ASM for salaries, wages, and
benefits increased .9 percent from 1992 to 1993.  This increase resulted from a
2.2 percent increase in salaries and wages, offset by a 5.0 percent decrease in
health benefit and workers' compensation costs per ASM.  Headcount for Southwest
increased 17.0 percent in 1993, slightly more than the 15.9 percent increase in
ASMs.  However, Employee productivity improved to 2,633 passengers handled per
Employee in 1993 from 2,597 in 1992.

Morris contracted out all ground handling services, which are included in "other
operating expenses."  Consequently, salaries, wages, and benefits on a per-ASM
basis are considerably lower for 

                                      F-7

<PAGE>
 
Morris than for Southwest contributing to the decrease in consolidated salaries,
wages, and benefits per ASM.

Profitsharing and Employee savings plan expenses per ASM increased 16.7 percent
in 1993. The increase was primarily the result of higher earnings in 1993. For
additional information, see Note 10 to the Consolidated Financial Statements.

Fuel and oil expenses per ASM decreased 2.6 percent in 1993 due to a 2.7 percent
reduction in the average cost per gallon of jet fuel from 1992. Jet fuel prices
remained relatively stable throughout 1993, continuing the trend which began in
1992, with quarterly averages ranging from $0.57 to $0.63 per gallon.

Maintenance materials and repairs per ASM increased 5.4 percent in 1993. This
increase was primarily the result of higher airframe component repairs and
higher amortization of capitalized scheduled airframe overhauls.

Agency commissions per ASM increased 6.0 percent in 1993 primarily due to
increased passenger revenues per ASM.

Aircraft rentals per ASM increased 30.0 percent in 1993. The increase was
primarily attributable to the expansion of Morris scheduled operations, which
leased 18 of its 21 aircraft, 11 of which were leased in 1993. Additionally, the
increase partially resulted from the sale/leaseback financing by Southwest,
since late 1992, of seven 737-300 aircraft with long-term operating leases. Also
in 1993, Southwest leased one used 737-300 aircraft under a long-term operating
lease and one used 737-200 aircraft under a short-term operating lease.

Depreciation expense per ASM decreased 8.5 percent in 1993 due to the expansion
of Morris, which, as stated above, consisted primarily of a leased aircraft
fleet.

Other operating expenses per ASM increased 13.8 percent from 1992 to 1993. This
increase is primarily the result of higher usage of contract services at Morris.
As previously discussed, Morris contracted for all ground handling service,
along with various other services that are handled internally at Southwest.

Other   "Other expenses(income)" included interest expense, interest income, and
nonoperating gains and losses. Interest expense, net of capitalized interest,
decreased 7.0 percent in 1993 due to the March 1, 1993 early redemption of $100
million in senior unsecured 9% Notes due 1996. See Note 6 to the Consolidated
Financial Statements for further information. Net nonoperating losses in 1993
resulted from the write-down of certain internal system development costs and
the settlement of certain employment-

                                      F-8

<PAGE>
 
related litigation for $1.7 million.

Income Taxes   The provision for income taxes increased in 1993, as a percentage
of income before income taxes and cumulative effect of accounting changes, to
40.6 percent from pro forma 38.1 percent in 1992. The increase was primarily the
result of the increase in the federal income tax rate. See Note 11 to the
Consolidated Financial Statements for further information.


LIQUIDITY AND CAPITAL RESOURCES

Cash provided from operations was $412.7 million in 1994, compared to $392.7
million in 1993.  During 1994, additional funds of $315.0 million were generated
from the sale and leaseback of ten new 737-300 aircraft subject to long-term
operating leases (increasing total commitments for operating leases by $619.0
million).

During 1994, capital expenditures of $788.6 million were primarily for the
purchase of 18 new 737-300 aircraft, one used 737-300 aircraft previously leased
by Morris, and progress payments for future aircraft deliveries. At December 31,
1994, capital commitments of the Company consisted primarily of scheduled
aircraft acquisitions.

As of January 1995, Southwest had one-hundred-sixteen 737s on firm order,
including twenty-five to be delivered in 1995, with options to purchase another
seventy-four.  Aggregate funding required for firm commitments  approximated
$3,042.7 million through the year 2001 of which $602.6 million related to 1995.
See Note 4 to the Consolidated Financial Statements for further information.

The Company recently completed the construction of a $10.0 million reservation
center in Little Rock, Arkansas, which began accepting calls on January 24,
1995, and announced that it will build an additional reservation center in
Oklahoma City scheduled to open in second quarter 1995.  Total estimated cost of
the new Oklahoma City reservation center is approximately $10.0 million.

As of December 31, 1994 and since 1990, the Company had authority from its Board
of Directors to purchase 3,750,000 shares of its common stock from time-to-time
on the open market. No shares have been purchased since 1990.

The Company has various options available to meet its capital and operating
commitments, including cash on hand at December 31, 1994 of $174.5 million,
internally generated funds, and a revolving credit line with a group of banks of
up to $300 million (none of which had been drawn at December 31, 1994). In
addition, the 

                                      F-9

<PAGE>
 
Company will also consider various borrowing or leasing options to maximize
earnings and supplement cash requirements.

At yearend, the Company had outstanding shelf registrations for the issuance of
$100 million senior unsecured notes and $98 million pass-through certificates
relating to sale/leaseback transactions. The Company presently intends to
utilize these sources of financing during 1995.

Cash provided from operations was $392.7 million in 1993 as compared to $282.1
million in 1992. During 1993, additional funds of $90.0 million were generated
from the sale and leaseback of three new 737-300 aircraft subject to long-term
operating leases (increasing total commitments for operating leases by $145.0
million). Morris also generated $17.8 million from certain bank borrowings.
These proceeds were primarily used to finance aircraft-related capital
expenditures and to provide working capital.

SOUTHWEST AIRLINES CO.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 1994


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation  The consolidated financial statements include the
accounts of Southwest Airlines Co. (Southwest) and its wholly owned subsidiaries
(the Company). All significant intercompany balances and transactions have been
eliminated.  Certain prior year amounts have been reclassified for comparison
purposes.

Cash and cash equivalents    Cash equivalents consist of investment grade
commercial paper issued by major financial institutions that are highly liquid
and have original maturity dates of three months or less.  Cash and cash
equivalents are carried at cost, which approximates market value.

Inventories  Inventories of flight equipment expendable parts, materials, and
supplies are carried at average cost. These items are charged to expense when
issued for use.

Property and equipment  Depreciation is provided by the straight-line method to
residual values over periods ranging from 15 to 20 years for flight equipment
(see Note 3) and 3 to 30 years for ground property and equipment. Property under
capital leases and related obligations are recorded at an amount equal to the
present value of future minimum lease payments computed on the basis of the
lessee's incremental borrowing rate or, when known, the interest rate implicit
in the lease. Amortization of property under capital leases is on a straight-
line basis over the lease term and is included in depreciation expense.

Aircraft and engine maintenance  The cost of engine overhauls and routine
maintenance costs for aircraft and engine maintenance are charged to maintenance
expense as incurred.  Scheduled airframe overhaul costs are capitalized at
amounts not to exceed the fair market value of the related aircraft and
amortized over the estimated periods benefited, presently 8 years.
Modifications that significantly enhance the operating performance or extend the
useful lives of aircraft or engines are capitalized and amortized over the
remaining life of the asset.

Revenue recognition    Passenger revenue is recognized when the transportation
is provided. Tickets sold but not yet used are included in "Air traffic
liability."

Frequent flyer awards The Company accrues the estimated incremental cost of
providing free travel awards earned under its Company Club Frequent Flyer
program.

Advertising  The Company expenses the production costs of advertising as
incurred.  Advertising expense for the years ended December 31, 1994, 1993, and
1992 was $79,475,000, $55,344,000, and $42,068,000, respectively.

2.  ACQUISITION

On December 31, 1993, Southwest exchanged 3,574,656 newly issued shares of its
common stock for all of the outstanding stock of Morris Air Corporation
(Morris), a low-fare commercial/charter air carrier based in Salt Lake City.
The acquisition was accounted for as a pooling of interests and, accordingly,
the Company's consolidated financial statements were restated to include the
accounts and operations of Morris for all periods prior to the acquisition.

Prior to 1993, Morris was treated as an S-Corporation for federal and state
income tax purposes under applicable provisions of the Internal Revenue Code and
various state tax laws.  Therefore, no provision for income taxes was made prior
to 1993.  Morris made regular cash distributions to its shareholders sufficient
to meet their tax liabilities.  Upon termination of S-Corporation status on
December 31, 1992, the undistributed S-Corporation retained earnings were
reclassified to capital in excess of par value.  Additionally, Morris
established $3,032,000 of deferred income taxes for the cumulative differences
in the timing of reporting certain items for financial statement and income tax
purposes.  These deferred taxes related primarily to depreciation.  The
establishment of deferred taxes was offset by a reduction of capital in excess
of par value.

Merger expenses of $10,803,000 relating to the merger of Southwest and Morris
have been included in 1993 operating expenses as required for financial
reporting purposes; however, these expenses have been separately reported as
"merger expenses" to reflect the impact of the nonrecurring expenses on
operating results.  Included in these one-time costs resulting from the merger
were $1,900,000 of various professional fees; $4,703,000 for disposal of
duplicate or incompatible property and equipment; and $4,200,000 for Employee
relocation and severance costs related to elimination of duplicate or
incompatible operations.  During 1994, the integration of Morris into Southwest
was substantially completed, including the disposal of incompatible property and
equipment and settlement of Employee relocation and severance costs.

3. ACCOUNTING CHANGES

Income Taxes  Effective January 1, 1993, the Company adopted Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS
109). As a result of adopting SFAS 109, the Company recorded deferred tax assets
of $6,977,000 and reduced deferred tax liabilities by $9,048,000 at January 1,
1993, which resulted in an increase to the Company's 1993 net income of
$16,025,000 ($.11 per share) for the cumulative effect of the accounting change.

Postretirement Benefits    Effective January 1, 1993, the Company adopted
Statement of Financial Accounting Standards No. 106, "Employers' Accounting for
Postretirement Benefits Other Than Pensions" (SFAS 106).  The cumulative effect
of this change in accounting method at January 1, 1993 reduced 1993 net income
by $766,000 (net of benefit from income taxes of $469,000) or $.01 per share.
The effect of adopting SFAS 106 on 1993 income before cumulative effect of
accounting changes was not material.

Scheduled Airframe Overhauls    Prior to January 1, 1992, the Company expensed
scheduled airframe overhaul costs as incurred.  This practice was adopted at a
time when costs were relatively constant from year to year and consistent with
the growth of the fleet.
 
Given the significant growth of the Company's fleet and the Company's 1991
modification of its airframe overhaul maintenance program with the Federal
Aviation Administration (FAA), Southwest changed its method of accounting for
scheduled airframe overhauls costs from the direct expense method to that of
capitalizing and amortizing the costs over the periods benefited.  The Company
believes this method is preferable because it results in charges to expense that
are consistent with the growth in the fleet; improves financial reporting; and
better matches revenues and expenses.

For the year ended December 31, 1992, the Company recognized approximately
$6,900,000 in amortization of airframe overhaul expense.  Had the direct expense
method been used to provide for scheduled airframe overhaul costs during the
year ended December 31, 1992, income before cumulative effect of accounting
change would have been reduced by approximately $9,800,000 (net of provision for
income taxes and profitsharing of approximately $8,800,000), or approximately
$.07 per share.

This change in accounting principle had the effect of a one-time adjustment
increasing net income for the year ended December 31, 1992 by approximately
$12,538,000 (net of provision for income taxes and profitsharing of
approximately $11,500,000).

Change in Accounting Estimate    Effective January 1, 1992, the Company revised
the estimated useful lives of its 737-200 aircraft from 15 years to 15-19 years.
This change was the result of the Company's assessment of the remaining useful
lives of its 737-200 aircraft following the recent promulgation of rules by the
FAA for the phase out of Stage 2 aircraft by December 31, 1999.  The effect of
this change was to reduce depreciation expense approximately $3,680,000, or $.03
per share, for the year ended December 31, 1992.

4. COMMITMENTS

The Company's contractual purchase commitments consist primarily of scheduled
aircraft acquisitions. Twenty-five 737-300 aircraft are scheduled for delivery
in 1995, 18 in 1996, and ten in 1997. Four 737-700s are scheduled for delivery
in 1997, 16 in 1998, 16 in 1999, 15 in 2000, and 12 in 2001.  In addition, the
Company has options to purchase up to eleven 737-300s in 1997 and up to sixty-
three 737-700s during 1998-2004. The Company has the option, which must be
exercised two years prior to the contractual delivery date, to substitute 737-
400s or 737-500s for the 737-300s to be delivered during 1997 and 737-600s or
737-800s for the 737-700s delivered subsequent to 1999. Aggregate funding needed
for these commitments was approximately $3,042.7 million, subject to adjustments
for inflation, due as follows: $602.6 million in 1995, $489.5 million in 1996,
$447.8 million in 1997, $445.4 million in 1998, $452.9 million in 1999, $366.0
million in 2000, and $238.5 million in 2001.  In addition, the Company has an
agreement in principle to lease two used 737-300 aircraft in 1995.

The Company uses jet fuel fixed price swap arrangements to hedge its exposure to
price fluctuations on approximately 5 percent of its annual fuel requirements.
As of December 31, 1994, the Company had jet fuel swap agreements with broker-
dealers to exchange monthly payments on notional quantities amounting to
2,100,000 gallons per month, over the ensuing three months.  Under the swap
agreements, the Company pays or receives the difference between the daily
average jet fuel price and a fixed price of approximately $.518 per gallon.
Gains and losses on such transactions are recorded as adjustments to fuel
expense and have been insignificant.  Although the agreements expose the Company
to credit loss in the event of nonperformance by the other parties to the
agreements, the Company does not anticipate such nonperformance.

In 1992, certain Convertible Subordinated Debentures issued by Southwest
Airlines Eurofinance N.V. were redeemed.  The principal amount of $35,000,000
was converted into 1,370,902 shares (unadjusted for the 1993 and 1992 stock
splits) of Southwest's common stock at the conversion price of $25.53 per share.
The conversion was primarily a noncash transaction and, therefore, was excluded
from the Statement of Cash Flows.

In addition to the credit facilities described above, Southwest has an unsecured
Bank Credit Agreement with a group of domestic banks that permits Southwest to
borrow through December 14, 1996 on a revolving credit basis up to $300 million.
Interest rates on borrowings under the Credit Agreement can be, at the option of
Southwest, the agent bank's prime rate, .30% over LIBOR, or .50% over domestic
certificate of deposit rates. The commitment fee is 0.1875% per annum. There
were no outstanding borrowings under this agreement at December 31, 1994 or
1993.

7. LEASES

The aircraft leases can generally be renewed at rates, based on fair market
value at the end of the lease term, for one to five years.  Most aircraft leases
have purchase options at or near the end of  the lease term at fair market
value, but generally not to exceed a stated percentage of the lessor's defined
cost of the aircraft.

8. COMMON STOCK

At December 31, 1994, the Company had common stock reserved for issuance
pursuant to Employee stock benefit plans (12,009,293 shares) and upon exercise
of rights pursuant to the Common Stock Rights Agreement (Agreement), as amended
(155,265,088 shares).

Pursuant to the Agreement, each outstanding share of the Company's common stock
is accompanied by one common share purchase right (Right). Each Right entitles
its holder to purchase one share of common stock at an exercise price of $16.67
and is exercisable only in the event of a proposed takeover, as defined by the
Agreement. The Company may redeem the Rights at $.0111 per Right prior to the
time that 20 percent of the common stock has been acquired by a person or group.
If the Company is acquired or if certain self-dealing transactions occur, as
defined in the Agreement, each Right will entitle its holder to purchase for
$16.67 that number of the acquiring company's or the Company's common shares, as
provided in the Agreement, having a market value of two times the exercise price
of the Right. The Rights will expire no later than July 30, 1996.
 
On May 19, 1993, the Company's Board of Directors declared a three-for-two stock
split, distributing 46,325,147 shares on July 15, 1993.  On May 20, 1992, the
Company's Board of Directors declared a two-for-one stock split, distributing
46,180,531 shares on July 15, 1992.

subsequent 1993 and 1992 stock splits) of its common stock (2,327,892 new shares
and 172,108 shares from treasury) in a public offering.  Net proceeds from the
sale of approximately $86,946,000 were added to the working capital of the
Company for general corporate purposes, including the acquisition of aircraft
and related equipment.

9. STOCK PLANS

In May 1991, the Company's stockholders approved the Incentive Stock Option Plan

Substantially all of Southwest's Employees are members of the Southwest Airlines
Co. Profitsharing Plan (the Plan). Total profitsharing expense charged to
operations in 1994, 1993, and 1992 was $52,782,000, $44,959,000, and

The Company sponsors Employee savings plans under Section 401(k) of the Internal
Revenue Code. The plans cover substantially all full-time Employees. The amount
of matching contributions varies by Employee group. Company contributions
generally vest over five years with credit for prior years' service granted.

$19,817,000, $13,986,000, and $11,611,000, respectively.

11. INCOME TAXES

Effective January 1, 1993, the Company changed its method of accounting for
income taxes from the deferred method to the liability method as required by
SFAS 109 (see Note 3).

Under SFAS 109, deferred income taxes reflect the net tax effects of temporary
differences between the carrying amounts of assets and liabilities for financial
reporting purposes and the amounts used for income tax purposes.  The components
of deferred tax assets and liabilities at December 31, 1994 and 1993 are as
follows (in thousands):

In August 1993, the Revenue Reconciliation Act of 1993 (the "1993 Act") was
enacted, which contains numerous provision changes including an increase in the
federal corporate income tax rate from 34 percent to 35 percent effective
January 1, 1993.  As a result, the Company recognized approximately $4.0 million
of additional expense related to deferred tax liabilities existing on January 1,
1993.

The provision for income taxes before the cumulative effect of accounting
changes is comprised of the following (in thousands):

In January 1994, Southwest received an examination report from the Internal
Revenue Service proposing certain adjustments to Southwest's income tax returns
for 1987 and 1988.  The adjustments relate to certain types of aircraft
financings consummated by Southwest, as well as other members of the aviation
industry during that time period.  Southwest intends to vigorously protest the
adjustments proposed with which it does not agree.  The industry's difference
with the IRS involves complex issues of law and fact that are likely to take a
substantial period of time to resolve.  Management believes that final
resolution of such protest will not have a materially adverse effect upon the
results of operations of Southwest.

The effective tax rate on income before cumulative effect of accounting changes
differed from the federal income tax statutory rate for the following reasons

REPORT OF ERNST & YOUNG LLP
INDEPENDENT AUDITORS
The Board of Directors and Shareholders
Southwest Airlines Co.

We have audited the accompanying consolidated balance sheets of Southwest
Airlines Co. as of December 31, 1994 and 1993, and the related consolidated
statements of income, stockholders' equity, and cash flows for each of the three
years in the period ended December 31, 1994. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Southwest Airlines
Co. at December 31, 1994 and 1993, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1994, in conformity with generally accepted accounting principles.

As discussed in Note 3, during 1993, the Company changed its method of
accounting for income taxes and postretirement benefits.  Also as discussed in
Note 3, during 1992, the Company changed its method of accounting for scheduled
airframe overhauls.

sale and support by CFM and the purchase by Airline from CFM of spare turbofan

Whereas, the Agreement has heretofore included a cumulative total of one-
hundred-forty-four (144) Firm and fifty-three (53) Option 737-300, 737-400,
and/or 737-500 aircraft for delivery through 1999; and

Whereas, (a) only eleven (11) of such 53 Option aircraft (3 in April 1997, 2 in
August 1997, 2 in September 1997 and 4 in October 1997) continue to be scheduled
for delivery to Airline (the "Eleven aircraft") and (b) the remainder of such 53
Option aircraft are replaced by a purchase agreement with Boeing (the "Aircraft
Purchase Agreement") for CFM56-7 (22,000 lbs. SlS thrust to 86 degreesF) 
powered 737- 700 aircraft as set forth in Attachment I to this Amendment No. 7
(the aircraft set forth in Attachment I being collectively referred to as the

Whereas, sixty-three (63) of the Aircraft (as defined in such Attachment I

          set forth in Section XIII, as amended, of Exhibit B of the GTA, (d)
          Letter Agreements Nos. 1 through 10 to the GTA, or (e) unless
          otherwise agreed to the contrary in writing by the parties, (i)
          applicable terms and conditions of the GTA shall hereafter likewise
          apply to CFM56-7 installed engines purchased from Boeing, spare
          engines, engine modules, spare parts, and other specified equipment
          purchased from CFM in support of Airline's 737-700 aircraft fleet and
          (ii) such equipment shall be included under the term Products as used
          in the GTA and applicable letter Agreements subsequent to letter

                                 -------------

SECTION XIV - SPECIAL GUARANTEES FOR CFM56-7 ENGINES
----------------------------------------------------

The following Special Guarantees have been tailored to Airline's 737-700 fleet
average flight conditions.  The delivery schedule upon which such Special
Guarantees are conditioned is set forth in Attachment I to Amendment No. 7 to
the GTA (the "Aircraft"), and the basis for such guarantees is described in
Attachment V to this Amendment No. 7 to the GTA.

A.   Material Cost Guarantee
     -----------------------

     CFM guarantees that the ten-year cumulative net material cost, including
     Life Limited parts material, for all engine Parts supported through CFM56
     Engine Spare parts Catalog sales for Airline's fleet of CFM56-7 engines
     will not exceed the following values per engine flight hour:

          $51.10, based on an average Aircraft utilization of       
               3600 hours per year; or

          $48.90, based on an average Aircraft utilization of       
               3200  hours per year.

     The appropriate guaranteed rate will be adjusted for escalation annually in
     the month of July in accordance with the provisions set forth in Exhibit D
     of the Aircraft Purchase Agreement using a base ECI of 123.7 and a base ICI
     of 118.3 (July 1993).

     Such guaranteed rates are based on a stub life of 4,000 flight cycles for
     each module at the same guaranteed rate of $51.10 or $48.90 per engine
     flight hour, as appropriate.  To the extent the fleetwide average exceeds
     4,000 flight cycles, costs attributable to such excess shall not be
     included in Airline's cumulative net material cost for purposes of
     calculating the material cost guarantee.  Excess costs due to stub lifes
     greater than 4,000 cycles shall be calculated component by component and
     excluded on a prorate cycle basis for those cycles greater than 4,000
     cycles.  This reconciliation shall be completed on a yearly basis.

     The cumulative net material cost is based on the actual price of
     replacements for Parts scrapped during the guarantee period, less any
     material credits issued under warranty, other guarantee, or other program
     considerations.  All other costs, including material handling fees, are
     excluded.

     Parts scrapped due to service bulletin compliance will be included in the
     guarantee at 100% less any credits, provided the service bulletins are
     agreed to by Airline and CFM.
<PAGE>
 
     In cases where a Parts repair procedure is required and is not available
     within six (6) months from receipt of Airline's request for such repair
     procedure, the Part may be scrapped unless CFM and Airline agree otherwise.

     Settlement of the ten (10)  year net cumulative Material Cost Guarantee
     will be on a yearly basis.  If at the time of any yearly settlement,
     Airline's cumulative net material cost under this guarantee exceeds the
     guarantee level, CFM will provide airline a credit against purchases from
     CFM in the amount of 65 percent (65%) of the actual cost overrun incurred
     by Airline since the last settlement.  In the event that (a) at the time of
     any yearly settlement the guarantee level is not met, (b) CFM provides
     Airline a credit, and (c) subsequently the guarantee overrun is reduced
     such that the cumulative guarantee level is met, then Airline shall return
     to CFM all credits previously issued under the guarantee, without interest.

B.   Performance Retention Guarantee
     -------------------------------

     CFM guarantees that the cumulative fleet average cruise fuel consumption
     deterioration of new CFM56-7 engines will not exceed an average of two
     percent (2%) during the first five (5) years of Airline's 737-700 revenue
     service.  This includes installed and spare engines to support all Aircraft
     delivered during the period of this guarantee.  Attachment VI to Amendment
     No. 7 to the GTA describes the method of measurement to be used.

     If at the end of the five-year guarantee period the guarantee level is
     exceeded, CFM will provide Airline with:

     1)   Reimbursement for the excess fuel consumed for that portion of the
          guarantee period during which the guarantee is exceeded, computed at
          Airline's average monthly cost of fuel; and

     2)   An extension of the guarantee to ten (10) years at a cumulative fuel
          consumption level of two and one half percent (2.5%), with
          reimbursement for the excess fuel consumed for the portion of years 6
          through 10 inclusive during which the guarantee is exceeded.

          This reimbursement will be in the form of a credit against purchases
          from CFM.

C.   New Engine EGt Deterioration Guarantee
     --------------------------------------

     CFM guarantees that each new CFM56-7 engine delivered to Airline either as
     an installed or spare engine will operate the first 7,000 engine flight
     hours without removal due to exceeding the certified maximum takeoff EGT
     limit.  Available on-wing performance restoration techniques to
<PAGE>
 
     regain EGT margin will be employed prior to engine removal.  If an engine
     is removed from an Aircraft during the guarantee period solely for
     exceeding the takeoff EGT limit, CFM will provide Airline a credit against
     purchases from CFM equivalent to Airline's cost of restoration, less fees,
     to restore adequate EGT margin to meet the guarantee.  As with the
     "Restored Engine EGT Deterioration Guarantee", a mutually agreed to
     workscope shall apply.  Any material credit issued under this guarantee
     will be applied as credit under the Material Cost Guarantee.

D.   Restored Engine EGT Deterioration Guarantee
     -------------------------------------------

     CFM guarantees that for five (5) years beginning with delivery of Airline's
     first 737-700 Aircraft, each CFM56-7 engine operated by Airline since
     original delivery thereof and restored to a mutually agreed to workscope
     will operate for 5,000 engine flight hours following installation without
     removal due to exceeding the certified maximum takeoff EGT limit.  If an
     engine is removed from an Aircraft during the guarantee period solely for
     exceeding the takeoff EGT limit, CFM will provide Airline a credit against
     purchases from CFM equivalent to Airline's cost of restoration, less fees,
     to restore adequate EGT margin to meet the guarantees.  Any material credit
     issued under this guarantee will be applied as credit under the Material
     Cost Guarantee.

                                 ------------

                     BASIS FOR CFM56-7 SPECIAL GUARANTEES
                     ------------------------------------

The special guarantees set forth in Attachment IV to Amendment No. 7 to the GTA
(the "Special Guarantees") have been developed specifically for Airline's new
installed and spare CFM56-7 (22,000 lbs.) engines (the "Engines").  Such 737-700
fleet based guarantees are contingent upon Airline accepting delivery of sixty-
three (63) firm, sixty-three (63) option, and forty-nine (49) rollover option
CFM456-7 powered 737-700 aircraft (the "Aircraft") in the time period described
in Attachment I to Amendment No. 7 to the GTA, and upon Airline procuring a
mutually agreed upon number of spare CFM56-7 engines and engine modules.  Such
Special Guarantees are also contingent upon Airline's Engines being identified
and maintained separately from other operators' engines at the repair agency,
and upon agreement between Airline and CFM regarding administration of the
Special Guarantees.

The Special Guarantees are based on an average flight leg of 0.95 hours or
greater, an average takeoff thrust derate of 10 percent or greater, and an
average Aircraft utilization of 3600 or 3200, as appropriate, hours per year
maximum.  Operation under different conditions including delivery of a lesser
number of aircraft, changes in delivery schedule from that described in
Attachment I to Amendment No. 7 to the GTA, and/or introduction of 737-700
aircraft with greater than 22,000 lb. thrust may require adjustment of the
guaranteed values.

The Special Guarantees require that Airline and CFM agree upon the workscope
necessary during each shop visit, that available on-wing maintenance and
performance restoration procedures are used to avoid unnecessary shop visits,
and that service bulletins agreed to between Airline and CFM are incorporated in
a timely manner.

The Material Cost Guarantee includes Foreign Object Damage (FOD) caused by birds
or hail.

Unless stated otherwise in the specific Special Guarantee, such Special
Guarantees commence with delivery of Airline's first Aircraft.

CFM will, with Airline's assistance, conduct an accounting at least annually to
determine the status of each of such Special Guarantees.

Special Guarantees shall not be the subject of claims and/or administration
directly between Airline and CFM under the GTA in the event (i) Airline accepts
a 737-700 aircraft maintenance cost guarantee from Boeing or any other third
party and (ii) such guarantee includes an integration of such Special Guarantees
as assigned by Airline to such third party and consented to by CFM.
<PAGE>
 
Also, in the event Airline accepts a proposal independent of Amendment No. 7
(including from GE or SOCHATA) for any type of power-by-the-hour service
contract for the Engines, Airline hereby agrees to assign all of the Special
Guarantees (except the Performance Retention Guarantee which would remain
between CFM and Airline even though such guarantee would be assignable by
Airline subject to administration in the case of an aircraft maintenance cost
guarantee) to the successful contractor for integration into said power-by-the-
hour service contract.

The General Conditions of the CFM Product Support Plan included in the GTA apply
to the Special Guarantees unless stated otherwise herein.

                        CFM56-7 CUMULATIVE FLEET AVERAGE
                        --------------------------------
                        PERFORMANCE RETENTION GUARANTEE
                        -------------------------------
                             METHOD OF MEASUREMENT
                             ---------------------

1.   Base point for the cumulative fleet average fuel flow guarantee is the
     average of the first twenty (20) revenue flight cruise points of each
     CFM56-7 engine covered by the GTA.

2.   Performance Retention (fuel consumption deterioration) is determined
     quarterly by comparing the cumulative fleet average of the quarterly data
     points with the base point.

3.   The period covered by this guarantee starts from the first revenue flight
     of the first Aircraft.

4.   CFM also requests Airline to submit to CFM on a monthly basis copies of
     performance trending printed out from the ADEPT (Aircraft Data Engine
     Performance Trending) or GEM's (Ground-base Engine Monitoring) fleet
     average program.

5.   Cruise data reported quarterly must include the following:

     A/C Number; Engine Serial Number (ESN); Date; Flight Number; Engine
     Position; Altitude; Mach Number; Total Air Temperature (TAT); and at Cruise
     Point; N1, Exhaust Gas Temperature (EGT), N2, Fuel Flow, and Bleed
     Configuration.

6.   If the deterioration of the cumulative fleet average fuel flow at N1
     exceeds the guarantee or if the deterioration trend suggests that the
     guarantee might be exceeded, then, the following actions may be initiated:

     a)   CFM Flight Audits.

     b)   Test Cell confirmation runs on specific engines, adjusted to account
          for sea level to altitude effects plus installation loss.  If the test
          cell run on a sample of engines shows more than this amount from new,
          this would support that the inflight guarantee has been exceeded.

7.   If, as a result of incorporation of service bulletins (other than mandatory
     campaign change) or other modifications, the initially established
     relationship of Engine fuel flow, thrust and fan speed (N1) is altered, the
     measured, calibrated fuel consumption shall be suitably corrected as
     mutually agreed to account for the effect of such change.

              CONDITIONS FOR DELAY/CANCELLATION OF SPARE ENGINES
              --------------------------------------------------


1.   Cancellation of Spare Engines
     -----------------------------

     In the event Southwest cancels any purchase order for, or otherwise fails
     to take delivery of, spare CFM engine(s), the parties agree that harm or
     damage will be sustained by CFM as a result.  The parties agree that if
     written notice of cancellation is not received at least 12 months prior to
     the scheduled delivery date of a spare engine to Southwest, any
     cancellation or failure to accept delivery thereafter will subject
     Southwest to a cancellation charge of 10% of the spare engine price
     (determined as of the date of scheduled engine delivery) which the parties
     acknowledge to be a reasonable estimate of the harm or damage to CFM.

     CFM shall retain any engine progress payments or other deposits (not to
     exceed 10% as noted above) made to CFM for such cancelled engine, and such
     progress payments will be applied to the above-described liquidated
     damages.

2.   Delay Charge for Spare Engines.
     -------------------------------

     In the event Southwest delays the scheduled delivery date of a spare engine
     for which CRFM has received a purchase order from Southwest, for a period,
     or cumulative period, of more than 24 months, such delay shall be
     considered a cancellation, and the applicable provisions hereof regarding
     the effect of cancellation shall apply.

  1.     Formula.

         The Airframe Price Adjustment will be determined at the time of
  Aircraft delivery in accordance with the following formula:

         Pa = (P)(L + M - 1)

         Where:

         Pa = Airframe Price Adjustment.

         L = .65 x  ECI
                   -----     
                   123.7
            
         M = .35 x  ICI
                   -----     
                   118.3
            
         P = Aircraft Basic Price (as set forth in Article 3.2 of this
             Agreement) less the base price of Engines (as defined in this
             Exhibit D-3) in the amount of $6,154,566.
            
       ECI = A value using the "Employment Cost Index for workers in
             aerospace manufacturing" (aircraft manufacturing, standard
             industrial classification code 3721, compensation, base month
             and year June 1989 = 100), as released by the Bureau of Labor
             Statistics, U.S. Department of Labor on a quarterly basis for
             the months of March, June, September and December, calculated as
             follows: A three-month arithmetic average value (expressed as a
             decimal and rounded to the nearest tenth) will be determined
             using the months set forth in the table below for the applicable
             Aircraft, with the released Employment Cost Index value
             described above for the month of March also being used for the
             months of January and February; the value for June also used for
             April and May; the value for September also used for July and
             August; and the value for December also used for October and
             November.
<PAGE>
 
Exhibit D-3
Page 2



     ICI =  The three-month arithmetic average of the released monthly
            values for the Industrial Commodities Index as set forth in the
            "Producer Prices and Price Index" (Base Year 1982 = 100) as
            released by the Bureau of Labor Statistics, U.S. Department of
            Labor values (expressed as a decimal and rounded to the nearest
            tenth) for the months set forth in the table below for the
            applicable Aircraft.

       In determining the value of L, the ratio of ECI divided by 123.7 will be
expressed as a decimal rounded to the nearest ten-thousandth and then multiplied
by .65 with the resulting value also expressed as a decimal and rounded to the
nearest ten-thousandth.

       In determining the value of M, the ratio of ICI divided by 118.3 will be
expressed as a decimal rounded to the nearest ten-thousandth and then multiplied
by .35 with the resulting value also expressed as a decimal and rounded to the
nearest ten-thousandth.

  2.   If at the time of delivery of an Aircraft Boeing is unable to determine
  the Airframe Price Adjustment because the applicable values to be used to
  determine the ECI and ICI have not been released by the Bureau of Labor
  Statistics, then:

       2.1   The Airframe Price Adjustment, to be used at the time of delivery
  of each of the Aircraft, will be determined by utilizing the escalation
  provisions set forth above. The values released by the Bureau of Labor
  Statistics and available to Boeing 30 days prior to scheduled Aircraft
  delivery will be used to determine the ECI and ICI values for the applicable
  months (including those noted as preliminary by the Bureau of Labor
  Statistics) to calculate the Airframe Price Adjustment. If no values have been
  released for an applicable month, the provisions set forth in Paragraph 2.2
  below will apply. If prior to delivery of an Aircraft the U.S. Department of
  Labor changes the base year for determination of the ECI or ICI values as
  defined above, such rebased values will be incorporated in the Airframe Price
  Adjustment calculation. The payment by Buyer to Boeing of the amount of the
  Purchase Price for such Aircraft, as determined at the time of Aircraft
  delivery, will be deemed to be the payment for such Aircraft required at the
  delivery thereof.

       2.2   If prior to delivery of an Aircraft the U.S. Department of Labor
  substantially revises the methodology used for the determination of the values
  to be used to determine the ECI and ICI values (in contrast to benchmark
  adjustments or other corrections of previously released values), or for any
  reason has not released values needed to determine the applicable Aircraft
  Airframe Price Adjustment, the parties will, prior to delivery of any such
  Aircraft, select a substitute for such values from data published by the
  Bureau of Labor Statistics or other similar data reported by non-governmental
  United States organizations, such substitute to lead in application to the
  same adjustment result, insofar as possible, as would have been achieved by
  continuing the use of the original values as they may have fluctuated during
  the applicable time period.  Appropriate revision of the formula will be made
  as required to reflect any substitute values.  However, if within 24 months
  from delivery of the Aircraft the Bureau of Labor Statistics should resume
  releasing values for the months needed to determine the Airframe Price
  Adjustment, such values will be used to determine any increase or decrease in
  the Airframe Price Adjustment for the Aircraft from that determined at the
  time of delivery of such Aircraft.

       2.3    In the event escalation provisions are made non-enforceable or
otherwise rendered null and void by any agency of the United States
Government, the parties agree, to the extent they may lawfully do so, to
equitably adjust the Purchase Price of any affected Aircraft to reflect an
allowance for increases or decreases in labor compensation and material costs
occurring since February, 1993, which is consistent with the applicable
provisions of paragraph 1 of this Exhibit D-3.

3.     For the calculations herein, the values released by the Bureau of Labor
Statistics and available to Boeing 30 days prior to scheduled Aircraft
delivery will be used to determine the ECI and ICI values for the applicable
months (including those noted as preliminary by the Bureau of Labor
Statistics) to calculate the Airframe Price Adjustment.

Note:  Any rounding of a number, as required under this Exhibit D-3 with respect
----   to escalation of the airframe price, will be accomplished as follows: if
       the first digit of the portion to be dropped from the number to be
       rounded is five or greater, the preceding digit will be raised to the
       next higher numbe r.

               ------------------------------------------------- 
                               (1993 BASE PRICE)
                               -----------------

(a)    The Aircraft Basic Price of each Aircraft set forth in Article 3.1 of
this Agreement includes an aggregate price for CFM56-3-B1 engines and all
accessories, equipment and parts therefor provided by the engine manufacturer
(collectively in this Exhibit D-3 called "Engines") of Six Million One Hundred
Fifty-Four Thousand Five Hundred Sixty-Six Dollars ($6,154,566). The adjustment
in Engine price applicable to each Aircraft ("Engine Price Adjustment" herein)
will be determined at the time of Aircraft delivery in accordance with the
following formula:

       D1  =  (Pb x  CPI  ) - Pb
                    ------  
                    130.51 

(b)  The following definitions will apply herein:

       D1  =  Engine Price Adjustment

       Pb  =  Aggregate Engine Base Price as set forth in Paragraph (a) above.

       CPI =  The Composite Price Index as determined in accordance with the
              formula set forth below. The Index values referred to below, to be
              used in determining the CPI, will be for the ninth month prior to
              the month of scheduled Aircraft delivery. Such Index values will
              be those prepared by the Bureau of Labor Statistics, U.S.
              Department of Labor.

              CPI =  L + M1 + M2 + M3

              L   =  The Labor Index for such month will be the quotient,
                     expressed as a decimal and rounded to the nearest
                     thousandth, of the "Hourly Earnings of Aircraft Engines and
                     Engine Parts Production Workers" SIC 3724, for such month
                     divided by Eleven Dollars and Sixteen Cents ($11.16). Such
                     quotient will be multiplied by 100 and then by fifty-five
                     percent (55%) with the value resulting from the latter
                     multiplication expressed as a decimal and rounded to the
                     nearest hundredth.
<PAGE>
 
              M1  =  The Industrial Commodities Index for such month will be
                     equal to ten percent (10%) of the Producer Price Index for
                     "all commodities other than Farm and Foods," Code 3-15,
                     (Base Year 1982 = 100) for such month, expressed as a
                     decimal and rounded to the nearest hundredth.

              M2  =  The Metals and Metal Products Index for such month will be
                     equal to twenty-five percent (25%) of the Producer Price
                     Index for "Metals and Metal Products," Code 10, (Base Year
                     1982 = 100) for such month expressed as a decimal and
                     rounded to the nearest hundredth.

              M3  =  The Fuel Index for such month will be equal to ten percent
                     (10%) of the Producer Price Index for "Fuel and Related
                     Products and Power," Code 5, (Base Year 1982 = 100) for
                     such month expressed as a decimal and rounded to the
                     nearest hundredth.

   130.51  =  Composite Price Index for October, 1992.

The factor (CPI divided by 130.51) by which the Aggregate Engine Base Price is
to be multiplied will be expressed as a decimal and rounded to the nearest
thousandth.

The Engine Price Adjustment will not be made if it would result in a decrease
in the aggregate Engine base price.

(c)    The values of the Average Hourly Earnings and Producer Price Indices used
in determining the Engine Price Adjustment will be those published by the Bureau
of Labor Statistics, U.S. Department of Labor as of a date 30 days prior to the
scheduled Aircraft delivery to Buyer. Such values will be considered final and
no Engine Price Adjustment will be made after Aircraft delivery for any
subsequent changes in published Index values.

(d)    If the U.S. Department of Labor, Bureau of Labor Statistics (i)
substantially revises the methodology (in contrast to benchmark adjustments or
other corrections of previously published data) or (ii) discontinues publication
of any of the data referred to above, CFMI agrees to meet jointly with Boeing
and Buyer to jointly select a substitute for the revised or discontinued data;
such substitute data to lead in application to the same adjustment result,
<PAGE>
 
insofar as possible, as would have been achieved by continuing the use of the
original data as it may have fluctuated had it not been revised or
discontinued.

Appropriate revision of the Engine Price Adjustment provisions set forth above
will be made to accomplish this result for the affected Engines.

In the event the Engine price escalation provisions are made non-enforceable or
otherwise rendered null and void by any agency of the United States Government,
CFMI agrees to meet with Boeing and Buyer to jointly agree, to the extent such
parties may lawfully do so, to adjust equitably the purchase price of any
affected Engine(s) to reflect an allowance for increases in labor, material and
fuel costs that have occurred from the period represented by the CPI to the
ninth month preceding the month of scheduled delivery of the applicable
aircraft.

NOTE:  Any rounding of a number, as required under this Exhibit D-3 with respect
----   to escalation of the Engine price, will be accomplished as follows: if
       the first digit of the portion to be dropped from the number to be
       rounded is five or greater, the preceding digit will be raised to the
       next higher number.

1.     Formula.
       -------
       The Airframe Price Adjustment will be determined at the time of Aircraft
delivery in accordance with the following formula:

       Pa = (P)(L + M - 1)

       Where:

       Pa = Airframe Price Adjustment.

       L =  .65 x  ECI
                  ----- 
                  125.9
            
       M =  .35 x  ICI
                  -----  
                  118.5
            
       P =  Aircraft Basic Price (as set forth in Article 3.2 of this
            Agreement) less the base price of Engines (as defined in this
            Exhibit D) in the amount of $6,277,658.
            
     ECI =  A value using the "Employment Cost Index for workers in
            aerospace manufacturing" (aircraft manufacturing, standard
            industrial classification code 3721, compensation, base month
            and year June 1989 = 100), as released by the Bureau of Labor
            Statistics, U.S. Department of Labor on a quarterly basis for
            the months of March, June, September and December, calculated as
            follows: A three-month arithmetic average value (expressed as a
            decimal and rounded to the nearest tenth) will be determined
            using the months set forth in the table below for the applicable
            Aircraft, with the released Employment Cost Index value
            described above for the month of March also being used for the
            months of January and February; the value for June also used for
            April and May; the value for September also used for July and
            August; and the value for December also used for October and
            November.

      ICI =     The three-month arithmetic average of the released monthly
                values for the Industrial Commodities Index as set forth in the
                "Producer Prices and Price Index" (Base Year 1982 = 100) as
                released by the Bureau of Labor Statistics, U.S. Department of
                Labor values (expressed as a decimal and rounded to the nearest
                tenth) for the months set forth in the table below for the
                applicable Aircraft.

       In determining the value of L, the ratio of ECI divided by 125.9 will be
expressed as a decimal rounded to the nearest ten-thousandth and then multiplied
by .65 with the resulting value also expressed as a decimal and rounded to the
nearest ten-thousandth.

       In determining the value of M, the ratio of ICI divided by 118.5 will be
expressed as a decimal rounded to the nearest ten-thousandth and then multiplied
by .35 with the resulting value also expressed as a decimal and rounded to the
nearest ten-thousandth.

2.     If at the time of delivery of an Aircraft Boeing is unable to determine
the Airframe Price Adjustment because the applicable values to be used to
determine the ECI and ICI have not been released by the Bureau of Labor
Statistics, then:

       2.1    The Airframe Price Adjustment, to be used at the time of delivery
of each of the Aircraft, will be determined by utilizing the escalation
provisions set forth above. The values released by the Bureau of Labor
Statistics and available to Boeing 30 days prior to scheduled Aircraft delivery
will be used to determine the ECI and ICI values for the applicable months
(including those noted as preliminary by the Bureau of Labor Statistics) to
calculate the Airframe Price Adjustment. If no values have been released for an
applicable month, the provisions set forth in Paragraph 2.2 below will apply. If
prior to delivery of an Aircraft the U.S. Department of Labor changes the base
year for determination of the ECI or ICI values as defined above, such rebased
values will be incorporated in the Airframe Price Adjustment calculation. The
payment by Buyer to Boeing of the amount of the Purchase Price for such
Aircraft, as determined at the time of Aircraft delivery, will be deemed to be
the payment for such Aircraft required at the delivery thereof.

       2.2    If prior to delivery of an Aircraft the U.S. Department of Labor
substantially revises the methodology used for the determination of the values
to be used to determine the ECI and ICI values (in contrast to benchmark
adjustments or other corrections of previously released values), or for any
reason has not released values needed to determine the applicable Aircraft
Airframe Price Adjustment, the parties will, prior to delivery of any such
Aircraft, select a substitute for such values from data published by the Bureau
of Labor Statistics or other similar data reported by non-governmental United
States organizations, such substitute to lead in application to the same
adjustment result, insofar as possible, as would have been achieved by
continuing the use of the original values as they may have fluctuated during the
applicable time period. Appropriate revision of the formula will be made as
required to reflect any substitute values. However, if within 24 months from
delivery of the Aircraft the Bureau of Labor Statistics should resume releasing
values for the months needed to determine the Airframe Price Adjustment, such
values will be used to determine any increase or decrease in the Airframe Price
Adjustment for the Aircraft from that determined at the time of delivery of such
Aircraft.

       2.3    In the event escalation provisions are made non-enforceable or
otherwise rendered null and void by any agency of the United States Government,
the parties agree, to the extent they may lawfully do so, to equitably adjust
the Purchase Price of any affected Aircraft to reflect an allowance for
increases or decreases in labor compensation and material costs occurring since
February, 1994, which is consistent with the applicable provisions of paragraph
1 of this Exhibit D.

3.     For the calculations herein, the values released by the Bureau of Labor
Statistics and available to Boeing 30 days prior to scheduled Aircraft delivery
will be used to determine the ECI and ICI values for the applicable months
(including those noted as preliminary by the Bureau of Labor Statistics) to
calculate the Airframe Price Adjustment.

Note:  Any rounding of a number, as required under this Exhibit D-4 with respect
----   to escalation of the airframe price, will be accomplished as follows: if
       the first digit of the portion to be dropped from the number to be
       rounded is five or greater, the preceding digit will be raised to the
       next higher number.

              ENGINE PRICE ADJUSTMENT - CFM INTERNATIONAL, INC.  
               -------------------------------------------------
                               (1994 BASE PRICE)
                               -----------------

(a)    The Aircraft Basic Price of each Aircraft set forth in Article 3.1 of
this Agreement includes an aggregate price for CFM56-3-B1 engines and all
accessories, equipment and parts therefor provided by the engine manufacturer
(collectively in this Exhibit D called "Engines") of Six Million Two Hundred
Seventy-Seven Thousand Six Hundred Fifty Eight Dollars ($6,277,658). The
adjustment in Engine price applicable to each Aircraft ("Engine Price
Adjustment" herein) will be determined at the time of Aircraft delivery in
accordance with the following formula:

       D1  =  (Pb x  CPI  ) - Pb
                    ------  
                    133.18

(b)  The following definitions will apply herein:

       D1  =  Engine Price Adjustment

       Pb  =  Aggregate Engine Base Price as set forth in Paragraph (a) above.

       CPI =  The Composite Price Index as determined in accordance with the
              formula set forth below. The Index values referred to below, to be
              used in determining the CPI, will be for the ninth month prior to
              the month of scheduled Aircraft delivery. Such Index values will
              be those prepared by the Bureau of Labor Statistics, U.S.
              Department of Labor.

              CPI =  L + M1 + M2 + M3

              L   =  The Labor Index for such month will be the quotient,
                     expressed as a decimal and rounded to the nearest
                     thousandth, of the "Hourly Earnings of Aircraft Engines and
                     Engine Parts Production Workers" SIC 3724, for such month
                     divided by Eleven Dollars and Sixteen Cents ($11.16). Such
                     quotient will be multiplied by 100 and then by fifty-five
                     percent (55%) with the value resulting from the latter
                     multiplication expressed as a decimal and rounded to the
                     nearest hundredth.

Exhibit D
Page 6



              M1  =  The Industrial Commodities Index for such month will be
                     equal to ten percent (10%) of the Producer Price Index for
                     "all commodities other than Farm and Foods," Code 3-15,
                     (Base Year 1982 = 100) for such month, expressed as a
                     decimal and rounded to the nearest hundredth.

              M2  =  The Metals and Metal Products Index for such month will be
                     equal to twenty-five percent (25%) of the Producer Price
                     Index for "Metals and Metal Products," Code 10, (Base Year
                     1982 = 100) for such month expressed as a decimal and
                     rounded to the nearest hundredth.

              M3  =  The Fuel Index for such month will be equal to ten percent
                     (10%) of the Producer Price Index for "Fuel and Related
                     Products and Power," Code 5, (Base Year 1982 = 100) for
                     such month expressed as a decimal and rounded to the
                     nearest hundredth.

   133.18  =  Composite Price Index for October, 1993.

The factor (CPI divided by 133.18) by which the Aggregate Engine Base Price is
to be multiplied will be expressed as a decimal and rounded to the nearest
thousandth.

The Engine Price Adjustment will not be made if it would result in a decrease
in the aggregate Engine base price.

(c)    The values of the Average Hourly Earnings and Producer Price Indices used
in determining the Engine Price Adjustment will be those published by the Bureau
of Labor Statistics, U.S. Department of Labor as of a date 30 days prior to the
scheduled Aircraft delivery to Buyer. Such values will be considered final and
no Engine Price Adjustment will be made after Aircraft delivery for any
subsequent changes in published Index values.

(d)    If the U.S. Department of Labor, Bureau of Labor Statistics (i)
substantially revises the methodology (in contrast to benchmark adjustments or
other corrections of previously published data) or (ii) discontinues publication
of any of the data referred to above, CFMI agrees to meet




                                      D-6
<PAGE>

Exhibit D 
Page 7



jointly with Boeing and Buyer to jointly select a substitute for the revised or
discontinued data; such substitute data to lead in application to the same
adjustment result, insofar as possible, as would have been achieved by
continuing the use of the original data as it may have fluctuated had it not
been revised or discontinued.

Appropriate revision of the Engine Price Adjustment provisions set forth above
will be made to accomplish this result for the affected Engines.

In the event the Engine price escalation provisions are made non-enforceable or
otherwise rendered null and void by any agency of the United States Government,
CFMI agrees to meet with Boeing and Buyer to jointly agree, to the extent such
parties may lawfully do so, to adjust equitably the purchase price of any
affected Engine(s) to reflect an allowance for increases in labor, material and
fuel costs that have occurred from the period represented by the CPI to the
ninth month preceding the month of scheduled delivery of the applicable
aircraft.

NOTE:  Any rounding of a number, as required under this Exhibit D-4 with respect
----   to escalation of the Engine price, will be accomplished as follows: if
       the first digit of the portion to be dropped from the number to be
       rounded is five or greater, the preceding digit will be raised to the
       next higher number.

                               -----------------


     SOUTHWEST AIRLINES CO., a Texas corporation (the "Company"), hereby
formulates and adopts the following 1995 SWAPA Non-Qualified Stock Option Plan.

     1.    PURPOSE.  This Plan is adopted pursuant to the Collective Bargaining
           --------                                                            
Agreement (the "Agreement") between the Company and the Southwest Airlines
Pilots Association ("SWAPA") ratified on January 12, 1995.

     2.    ADMINISTRATION.  This Plan shall be administered by an Administrative
           ---------------                                                      
Committee (the "Committee") consisting of not more than five (5) persons
designated from time to time by the Chief Executive Officer of the Company,
including as one of its members the President of SWAPA or his or her designee.
Members of the Committee may be removed or replaced at any time by the Chief
Executive Officer of the Company.  The Administrative Committee shall select one
of its members as Chairman and shall adopt such rules and regulations as it
shall deem appropriate concerning the holding of its meetings, the transaction
of its business and the administration of this Plan.  A majority of the whole
Committee shall constitute a quorum, and the act of a majority of the members of
the Committee present at a meeting at which a quorum is present shall be the act
of the Committee; any decision or determination reduced to writing and signed by
a majority of the members of the Administrative Committee shall be fully as
effective as if made by a majority vote at a meeting duly called and held.

     3.    GRANT OF OPTIONS; PERSONS ELIGIBLE.  The Stock Option Committee of 
           -----------------------------------                              
the Board of Directors of the Company, or such other committee as may be
appointed by the Board, shall have the authority and responsibility, within the
limitations of this Plan, to grant options from time to time to persons employed
as pilots (including pilots in management positions retaining seniority numbers)
by the Company or Morris Air Corporation pursuant to the Agreement and as set
forth in the schedule attached as Exhibit A and made a part hereof. Initial
Grants (as defined in Exhibit A) shall be granted at an exercise price of $20
per share; thereafter, Options shall be granted at an exercise price equal to
the fair market value of the Common Stock of the Company on the date of the
grant of the option plus five percent (5%). Only persons who are employed as
pilots of SWA or Morris Air Corporation on the date of the grant may be granted
options under this Plan; under no circumstances shall executive officers of the
Company be eligible to receive options hereunder.
<PAGE>
 
     4.    DEFINITIONS.  An employee receiving any option under this Plan is
           ------------                                                     
hereinafter referred to as an "Optionee."  Any reference herein to the
employment of an Optionee with the Company shall include only employment with
the Company or Morris Air Corporation.  The fair market value of the Common
Stock on any day shall be the mean between the highest and lowest quoted selling
prices of the Common Stock on such day as reported by the primary national stock
exchange on which such stock is listed.  If no sale shall have been made on that
day, or if the Common Stock is not listed on a national exchange at that time,
fair market value will be determined by the Committee.

     5.    STOCK SUBJECT TO OPTIONS.  Subject to the provisions of paragraph 12,
           -------------------------                                            
the number of shares of the Company's Common Stock subject at any one time to
options, plus the number of such shares then outstanding pursuant to exercises
of options, granted under this Plan, shall not exceed 18,000,000 shares.  If,
and to the extent the options granted under this Plan terminate or expire
without having been exercised, new options may be granted with respect to the
shares covered by such terminated or expired options; provided that the granting
and terms of such new options shall in all respects comply with the provisions
of this Plan.

     Shares sold or distributed upon the exercise of any option granted under
this Plan may be shares of the Company's authorized and unissued Common Stock,
shares of the Company's issued Common Stock held in the Company's treasury, or
both.

     There shall be reserved at all times for sale or distribution under this
Plan a number of shares of Common Stock (either authorized and unissued shares
or shares held in the Company's treasury, or both) equal to the maximum number
of shares which may be purchased or distributed upon the exercise of options
granted under this Plan.

     Exercise of an Option in any manner shall result in a decrease in the
number of shares of Common Stock which may thereafter be available, both for
purposes of this Plan and for sale to any one individual, by the number of
shares as to which the Option is exercised.

     6.    EXPIRATION AND TERMINATION OF THE PLAN.  This Plan will expire on
           ---------------------------------------                          
January 31, 2007.

     No modification, extension, renewal or other change in any option granted
under this Plan shall be made after the grant of such option unless the same is
consistent with the provisions of this Plan.

granted pursuant to this Plan or the disposition of shares of Common Stock
acquired by exercise of an Option results in compensation income to the Optionee
for federal or state income tax purposes, the Optionee shall deliver to the
Company at the time of such exercise or disposition such amount of money as the
Company may require to meet its obligation under applicable tax laws or
regulations, and, if the Optionee fails to do so, the Company is authorized to

withheld by reason of such resulting compensation income.

     (e)  Delivery of Shares.  The Company shall cause shares to be delivered to
          ------------------                                                    
the Optionee (or the person exercising the Optionee's options in the event of
death) as soon as practicable after the exercise date.
 
     9.   NONTRANSFERABILITY OF OPTIONS.  No option granted under this Plan or
          ------------------------------                                      
any right evidenced thereby shall be transferable by the Optionee other than by
will or the laws of descent and distribution.  During the lifetime of an
Optionee, only the Optionee (or his or her guardian or legal representative) may
exercise his or her options.

     In the event of the Optionee's death during his or her employment with the
Company, during the three-month period following the date of termination of such
employment, or during the 24-month period following FAA-mandated retirement, the
Optionee's options shall thereafter be exercisable, as provided in paragraph
7(b), by his or her executor or administrator, or by the person who acquires
such options by will or the laws of descent and distribution or otherwise by
reason of the death of the Optionee.

     10.  RIGHTS OF OPTIONEE.  Neither the Optionee nor his or her executors,
          -------------------                                                
administrators, or legal representatives shall have any of the rights of a
shareholder of the Company with respect to the shares subject to an option
granted under this Plan until certificates for such shares shall have been
issued upon the exercise of such option.

     11.  RIGHT TO TERMINATE EMPLOYMENT.  Nothing in this Plan or in any option
          ------------------------------                                       
granted under this Plan shall confer upon any Optionee the right to continue in
the employment of the Company or affect the right of the Company or any of its
subsidiaries to terminate the Optionee's employment at any time; subject,
however, to the provisions of the Agreement.

     12.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION, ETC.
          -----------------------------------------------

     (a)   The existence of the Plan and the options granted hereunder shall not
affect in any way the right or power of the Board of Directors or the
shareholders of the Company to make or authorize any adjustment,
recapitalization, reorganization or other change in the Company's capital
structure or its business, any merger or consolidation of the Company, any issue
of debt or equity securities ahead of or affecting Common Stock or the rights
thereof, the dissolution or liquidation of the Company or any sale, lease,
exchange or other disposition of all or any part of its assets or business or
any other corporate act or proceeding.

     (b)   The shares with respect to which options may be granted are shares of
Common Stock as presently constituted, but if, and whenever, prior to the
expiration of an option theretofore granted, the Company shall effect a
subdivision or consolidation of shares of Common Stock or the payment of a stock
dividend on Common Stock without receipt of consideration by the Company, the
number of shares of Common Stock with respect to which such option may
thereafter be exercised (i) in the event of an increase in the number of
outstanding shares shall be proportionately increased, and the purchase price
per share shall be proportionately reduced, and (ii) in the event of a reduction
in the number of outstanding shares shall be proportionately reduced, and the
purchase price per share shall be proportionately increased; likewise, the
number of shares to be granted pursuant to the schedule set forth in Exhibit A
shall be appropriately adjusted.  In the event of any such change in the
outstanding Common Stock, the aggregate number of shares available under the
Plan shall be appropriately adjusted by the Board of Directors of the Company,
whose determination shall be conclusive.

     (c)   If the Company recapitalizes or otherwise changes its capital
structure, thereafter upon any exercise of an option theretofore granted the
Optionee shall be entitled to purchase under such option, in lieu of the number
of shares of Common Stock as to which such option shall then be exercisable, the
number and class of shares of stock and securities to which the Optionee would
have been entitled pursuant to the terms of the recapitalization if, immediately
prior to such recapitaliza-

tion, the Optionee had been the holder of record of the number of shares of
Common Stock as to which such option is then exercisable.  If the Company shall
not be the surviving entity in any merger or consolidation (or survives only as
a subsidiary of an entity other than a previously wholly-owned subsidiary of the
Company) or if the Company is to be dissolved or liquidated, then unless a
surviving corporation assumes or substitutes new options for Options then
outstanding hereunder (i) the time at which such Options may be exercised shall
be accelerated and such Options shall become exercisable in full on or before a
date fixed by the Company prior to the effective date of such merger or
consolidation or such dissolution or liquidation, and (ii) upon such effective
date Options shall expire.

     (d)   Except as hereinbefore expressly provided, the issuance by the 
Company of shares of stock of any class or securities convertible into shares of
stock of any class, property, labor or services, upon direct sale, upon the
exercise of rights or warrants to subscribe therefor, or upon conversion of
shares or obligations of the Company convertible into such shares or other
securities, and in any case whether or not for fair value, shall not affect, and
no adjustment by reason thereof shall be made with respect to, the number of
shares of Common Stock subject to options theretofore granted or to be granted
or the purchase price per share.

     13.   PURCHASE FOR INVESTMENT AND LEGALITY.  The Optionee, by acceptance of
           ------------------------------------                                
any option granted under this Plan, shall represent and warrant to the Company
that the purchase or receipt of shares of Common Stock upon the exercise thereof
shall be for investment and not with a view to distribution, provided that such
representation and warranty shall be inoperative if, in the opinion of counsel
to the Company, a proposed sale or distribution of such shares is pursuant to an
applicable effective registration statement under the Securities Act of 1933 or
is, without such representation and warranty, exempt from registration under
such Act.  The Company shall file a Registration Statement on Form S-8 pursuant
to the Securities Act of 1933, as amended, covering the shares to be offered
pursuant to the Plan and will use its best efforts to maintain such registration
at all times necessary to permit holders of options to exercise them.

     The obligation of the Company to issue shares upon the exercise of an
option shall also be subject as conditions precedent to compliance with
applicable provisions of the Securities Act of 1933, the Securities Exchange Act
of 1934, state securities laws, rules and regulations under any of the foregoing
and applicable requirements of any securities exchange upon which the Company's
securities shall be listed.

     The Company may endorse an appropriate legend referring to the foregoing
restrictions upon the certificate or certificates representing any shares issued
or transferred to the Optionee upon the exercise of any option granted under
this Plan.

     14.   EFFECTIVE DATE OF PLAN.  This Plan shall become effective on January
           -----------------------                                             
12, 1995 upon its adoption by the Board of Directors of the Company.
