                                 MARCH 31, 1999


1.   BASIS OF PRESENTATION

         The unaudited condensed financial statements included herein have been
prepared by America West Airlines, Inc., ("AWA" or the "Company"), a
wholly-owned subsidiary of America West Holdings Corporation ("Holdings"),
pursuant to the rules and regulations of the Securities and Exchange Commission
and do not include all information and footnotes required by generally accepted
accounting principles. In the opinion of management, the condensed financial
statements reflect all adjustments, which are of a normal recurring nature,
necessary for a fair presentation. The accompanying condensed financial
statements should be read in conjunction with the financial statements and
related notes thereto included in the Company's Annual Report on Form 10-K for
the year ended December 31, 1998.

2.    STOCK REPURCHASE PROGRAM

                  In the first quarter 1999 AWA repurchased 177,900 of its
publicly traded warrants to purchase common stock of Holdings for approximately
$1.4 million. The equity repurchases were made pursuant to a stock repurchase
program encompassing all of AWA's publicly traded warrants by August 25, 1999.

         In April 1999 AWA repurchased 199,500 of its publicly traded warrants
to purchase common stock of Holdings for approximately $2.0 million.

3.    ADVANCES TO PARENT COMPANY AND AFFILIATE

                  As of March 31, 1999 AWA has advances to Holdings of $119.6
million. In addition, AWA has net obligations of $5.9 million due to The Leisure
Company ("TLC"), a wholly owned subsidiary of Holdings. All amounts bear
interest at market rates.

4.       BORROWING UNDER CREDIT FACILITY

         On February 19, 1999 AWA borrowed $94.3 million, the total amount then
available under its senior secured revolving credit facility, to provide
additional liquidity in the event of service disruptions related to the
Company's contract negotiations with its flight attendants. On March 20, 1999
the Company reported that it had reached a tentative agreement with the
Association of Flight Attendants ("AFA") on a five-year collective bargaining
agreement. On April 30, 1999 the AFA announced that AWA's flight attendants had
ratified the agreement. (See Other Information - "Labor Relations" in
Management's Discussion and Analysis of Financial Conditions and Results of
Operations.) The Company repaid this amount on April 19, 1999 in accordance with
the terms of the credit facility.

5.    SEGMENT DISCLOSURES

         AWA is one reportable segment. Accordingly, the segment reporting
financial data required by Statement of Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related Information" is

6.    INTEREST IN ACQUISITION OR BUSINESS COMBINATION

         On January 20, 1999 Holdings announced that it had been contacted by a
number of airlines expressing interest in possible transactions ranging from a
strategic alliance to a merger or similar business combination. On February 22,
1999 Holdings announced that it had terminated consideration of all such
unsolicited expressions of interest in the Company.

                                 MARCH 31, 1999


         For the three months ended March 31, 1999 and 1998, AWA realized
operating income of $48.9 million and $47.8 million, respectively. Income before
income taxes for the three month period in 1999 was $44.8 million compared to
$42.9 million in 1998. Income tax expense for financial reporting purposes was
$19.9 million and $18.5 million in the first quarters of 1999 and 1998,
respectively.

         Total operating revenues for the 1999 first quarter were a record
$506.5 million. Passenger revenues were $478.6 million for the three months
ended March 31, 1999, an increase of $34.8 million or 7.8% from first quarter
1998. A 10.8% increase in revenue passenger miles ("RPMs") more than offset a
7.7% increase in capacity as measured by available seat miles ("ASMs"),
resulting in a 1.8 point increase in load factor (the percentage of available
seats that are filled with revenue passengers). Revenue per passenger mile
("yield") decreased 2.6% to 11.88 cents, driven largely by the 6.9% increase in
stage length. Passenger revenue per available seat mile ("RASM") for the quarter
increased slightly to 7.60 cents, despite the increased stage length. Cargo and
other revenues increased 2.5% to 27.8 million for the first quarter of 1999.

         Operating expenses increased $34.4 million in the first quarter of 1999
or 8.1% as compared to the 1998 first quarter, while ASMs increased 7.7%. As a
result, CASM increased 0.4% to 7.27 cents in the first quarter of 1999 from 7.24
cents for the comparable 1998 period. Significant changes in the components of
CASM are explained as follows:

-    Salaries and related costs per ASM increased 3.4%. The contract with
     International Brotherhood of Teamsters, covering the airlines mechanics,
     which was signed in October 1998 and included higher wage rates, together
     with longevity-related salary level increases required by the pilot
     contract, contributed to higher salary expenses in 1999.

-    Aircraft rent expense per ASM increased 3.5% due to the net addition of
     nine leased aircraft to the fleet during the 1999 quarter as compared to
     1998.

-    Other rents and landing fees expense per ASM decreased 7.8% in the first
     quarter of 1999 as fewer spare parts were on loan from other airlines and
     landings were relatively flat quarter-over-quarter while ASMs increased
     7.7%.

-    Aircraft fuel expense per ASM decreased 18.1% due to a 17.4% decrease in
     the average price paid by AWA per gallon of fuel to 44.58 cents in the 1999
     quarter from 53.99 cents in 1998.

-    Agency commissions expense per ASM decreased 12.8% as the cost reduction
     associated with the institution of the $50 commission cap implemented on
     May 1, 1998 more than offset the effects of higher passenger revenues in
     the 1999 first quarter.

-    Aircraft maintenance materials and repairs expense per ASM increased 6.5%
     due primarily to an increase in capitalized maintenance amortization
     expense of $7.2 million for the first quarter of 1999 when compared to the
     1998 first quarter.

-    Depreciation and amortization expense per ASM decreased 11.9% due primarily
     to the increase in the average depreciable life of certain owned Boeing
     737-200 aircraft that will be modified to meet the Federal Aviation
     Administration's ("FAA") Stage III noise reduction requirements, which
     reduced depreciation expense in the 1999 first quarter by $2.0 million.

                                 MARCH 31, 1999


-    Amortization of excess reorganization value expense per ASM decreased 7.2% 
     due to the 7.7% increase in ASMs.

-    Other operating expenses per ASM increased 12.0% to 1.68 cents from 1.50
     cents primarily due to the effect in the first quarter 1999 of non-salary
     related Year 2000 costs ($6.4 million), information systems-related
     contract labor ($1.6 million) and higher catering costs ($1.8 million).

         Net nonoperating expenses decreased $0.8 million to $4.1 million in the
first quarter of 1999 from $4.9 million in 1998. Nonoperating expenses in the
first quarter of 1999 included $0.7 million of interest expense associated with
AWA's $94.3 million borrowing under its revolving credit facility on February
19, 1999. (See Note 4. "Borrowing Under Credit Facility" in Notes to Condensed
Financial Statements.) AWA also earned $0.5 million of interest income as the
borrowing proceeds were invested in cash equivalents. Excluding these amounts as
well as $1.7 million of interest income and $1.7 million of interest expense
associated with inter-company notes, the quarter-over-quarter change was
primarily due to a net decrease in interest expense as average outstanding debt,
excluding the $94.3 million, was $15.8 million lower in the first quarter of
1999 as compared to 1998.

LIQUIDITY AND CAPITAL RESOURCES

         Unrestricted cash and cash equivalents and short-term investments at
March 31, 1999 totaled $248.3 million. This amount includes $94.3 million AWA
had drawn under its revolving credit facility, which was invested in cash
equivalents (see Note 4, "Borrowing Under Credit Facility" in Notes to Condensed
Financial Statements). Excluding the $94.3 million, unrestricted cash and cash
equivalents and short-term investments increased $19.3 million to $154.0 million
at March 31, 1999 from $134.7 million at December 31, 1998. Net cash provided by
operating activities decreased to $70.3 million for the quarter ended March 31,
1999 from $91.6 million in first quarter 1998 due principally to the
period-over-period change in air traffic liability, which grew 15.9% in the 1999
period as compared to 32.4% in the 1998 period. Net cash used in investing
activities decreased to $21.4 million for the 1999 period from $58.5 million for
the 1998 period. This decrease was primarily due to the sales of short-term
investments totaling $18.2 million in the 1999 period as compared to purchases
of $14.8 million of short-term investments in 1998. Net cash provided by
financing activities was $83.0 million for the 1999 first quarter as compared to
$42.4 million used in financing activities in the 1998 period. The 1999 period
included the above mentioned $94.3 million borrowing under AWA's revolving
credit facility offset in part by $9.9 million of debt repayments and purchases
of AWA warrants totaling $1.4 million. In first quarter 1998 AWA repaid $30
million of revolving credit facility debt and repurchased $5.7 million of
warrants.

         Operating with a working capital deficiency is common in the airline
industry as tickets sold for transportation which have not yet been provided are
classified as a current liability while the related income-producing assets, the
aircraft, are classified as non-current. The company's working capital
deficiency at March 31, 1999 was $89.4 million.

         Long-term debt maturities through 2001 consist primarily of principal
amortization of notes payable secured by certain of AWA's aircraft and, in 1999,
the $94.3 million borrowing under the revolving credit facility. Such maturities
are $172.8 million, $19.9 million and $19.8 million, respectively, for the
remainder of 1999, 2000 and 2001. On April 19, 1999 the Company repaid the $94.3
million in accordance with the terms of the credit facility. Management expects
to fund the remaining long-term debt maturities with cash from operations or by
refinancing the underlying obligations, subject to availability and market
conditions.

         At March 31, 1999 AWA had a commitment to AVSA S.A.R.L., an affiliate
of Airbus Industrie ("AVSA"), to purchase a total of 27 Airbus aircraft, with 12
remaining to be delivered in 1999. AWA also has an option to purchase 47 more
Airbus aircraft of which seven are subject to reconfirmation by AWA. The
aggregate net cost of firm commitments remaining under the aircraft order is
approximately $1.0 billion based on a 3.5% annual price escalation. A default by
AWA under the AVSA purchase commitment could have a material adverse effect on
AWA.

         In October 1998 America West Airlines 1998-1 Pass Through Trusts issued
$190.5 million in Pass Through Trust Certificates in connection with the
financing of six Airbus A319 aircraft and two Airbus A320 aircraft to be
purchased from AVSA. The Pass Through Trust Certificates are not direct
obligations of or guaranteed by AWA. The combined effective interest rate on the
financing is 6.99%. Three Airbus A319 aircraft that are the subject of this
financing were delivered in 1998. One Airbus A320 aircraft was delivered in the
first quarter of 1999 and the remaining aircraft will be delivered through July
1999.

         AWA has also arranged for financing from AVSA for approximately
two-thirds of the firm commitment to purchase aircraft from AVSA. AWA intends to
seek additional financing (which may include public debt financing or private
financing) in the future when and as appropriate. There can be no assurance that
sufficient funding will be obtained for all aircraft.

                                 MARCH 31, 1999


         As of March 31, 1999, AWA's fleet consisted of 112 aircraft of which 11
aircraft met the FAA's Stage II (but not Stage III) noise reduction requirements
and must be retired or significantly modified prior to the year 2000. AWA
intends to outfit seven aircraft with hush kits to comply with Stage III
requirements. The remaining four non-compliant aircraft will be retired.

         Capital expenditures for the quarters ended March 31, 1999 and 1998
were approximately $43.2 million and $36.7 million, respectively. Included in
these amounts are capital expenditures for capitalized maintenance of
approximately $27.4 million for the first quarter of 1999 and $16.7 million for
the first quarter of 1998.

         Certain of AWA's long-term debt agreements contain minimum cash balance
requirements, leverage ratios, coverage ratios and other financial covenants
with which AWA was in compliance at March 31, 1999.

OTHER INFORMATION

LABOR RELATIONS

         On March 20, 1999 the Company reported that it had reached a tentative
agreement with the AFA, which represents AWA's approximately 2,150 flight
attendants, on a five-year collective bargaining agreement. On April 30, 1999
the AFA announced that AWA's flight attendants had ratified the agreement with
83% of the votes cast for ratification. On March 22, 1999 the Company announced
that based on the terms of this agreement and estimates of fuel prices at that
time, it expected AWA's 1999 CASM to increase approximately 1% compared to 1998.

         In October 1998 the Transportation Workers Union ("TWU") filed an
application with the National Mediation Board ("NMB") seeking certification as
the bargaining representative for AWA's approximately 2,000 fleet service
workers. An election on this application was authorized by the NMB. In January
1999 the NMB advised that 53 percent of eligible voters cast ballots in favor of
representation by the TWU. The Company has challenged the results of that
election based on allegations of misconduct by union organizers. Despite finding
evidence of union misconduct, on April 13, 1999 the NMB issued a decision
certifying the TWU as bargaining representative for the fleet service employees.
The Company cannot predict the form of this future collective bargaining
agreement and therefore the effect, if any, on AWA's operations or financial
performance.

YEAR 2000 COMPLIANCE PROGRAM AND RISKS

         The Year 2000 issue results from computer programs being written using
two digits rather than four to define the applicable year. As a consequence,
time-sensitive computer equipment and software may recognize a date using "00"
as the year 1900 rather than the year 2000. Many of the Company's systems,
including information and computer systems and automated equipment, will be
affected by the Year 2000 issue. The Company is also heavily reliant on the
FAA's management of the nation's air traffic control system, local authorities'
management of the airports at which AWA operates, and vendors to provide goods
(fuel, catering, etc.), services (telecommunications, data networks, satellites,
etc.) and data (frequent flyer partnerships, alliances, etc.)

                                 MARCH 31, 1999


                  The Company has underway a Year 2000 Project (the "Project" or
"Year 2000 Project") to identify the programs and infrastructure that could be
affected by the Year 2000 issue and is implementing a plan to resolve the
problems identified on a timely basis. The Project requires the Company to
devote a considerable amount of internal resources and hire substantial external
resources to assist with the implementation and monitoring of the Project, and
will require the replacement of certain equipment and modification of certain
software.

         The Company believes that its Year 2000 Project will be completed prior
to any currently anticipated significant impact on the Company arising from the
Year 2000 issue. The Project is divided into three main sections, including
information technology ("IT") systems, embedded systems and third party
compliance. The five phases of the IT and embedded systems sections include
inventory, assessment, renovation, user testing and implementation. The
inventory and assessment phases of the IT systems are substantially completed
and the remaining phases of the IT systems are expected to be completed in the
second quarter of 1999. The inventory phase of the embedded systems is
substantially completed and the remaining phases are underway and are expected
to be completed during the second and third quarters of 1999.

         The Company currently estimates that the total cost of its Year 2000
Project will be approximately $48 million, which will be funded from operating
cash flows. These costs exclude approximately $7 million of normal system
software and equipment upgrades and replacements which the Company anticipated
incurring in the ordinary course of business regardless of the Year 2000 issue.
As of March 31, 1999 the Company had incurred approximately $21 million of
non-capital expenditures in connection with the Year 2000 Project. The Company
expects that approximately $39 million of the costs have been or will be
expensed as incurred and the Company has had or will have approximately $9
million of capital expenditures.

         The costs and expected completion date of the Company's Year 2000
Project are based on management's best estimates, and reflect assumptions
regarding the availability and cost of personnel trained in this area, the
compliance plans of third parties and similar uncertainties. However, due to the
complexity and pervasiveness of the Year 2000 issue and in particular the
uncertainty regarding the compliance programs of third parties, no assurance can
be given that these estimates will be achieved, and actual results could differ
materially from those anticipated. If the Company's plan to address the Year
2000 issue is not successfully or timely implemented, the Company may need to
devote more resources to the process and additional costs may be incurred, which
could have a material adverse effect on the Company's financial condition and
results of operations.

         The failure to correct a material Year 2000 problem could result in an
interruption in, or failure of, certain normal business activities or
operations. While difficult to predict, we speculate that the most reasonably
likely worst case Year 2000 scenario will result from the failure of third
parties, including operators of airports and air traffic control systems, to
resolve their Year 2000 compliance issue. The Company has initiated
communications with such parties and significant suppliers and vendors with
which the Company's systems interface and upon which the Company's business
depends in an effort to reduce any adverse impact of the Year 2000 issue. There
can be no assurance, however, that the systems of such third parties will be
modified on a timely basis and any such failure may have a material adverse
effect on the Company's financial condition and results of operations.

         As a component of its Year 2000 Project, the Company is developing a
comprehensive analysis of the operational problems and costs (including loss of
revenues) that would be reasonably likely to result from the failure by the
Company and certain third parties to complete efforts necessary to achieve Year
2000 compliance on a timely basis. The Company is developing contingency plans
designed to enable it to continue operations, consistent with the highest
standards of safety, in the event of any such third party failures.

ADDITIONAL INFORMATION

         The air travel business historically fluctuates in response to general
economic conditions. The airline industry is sensitive to changes in economic
conditions that affect business and leisure travel and is highly susceptible to
unforeseen events that result in declines in air travel, such as political
instability, regional hostilities, recession, fuel price escalation, inflation,
adverse weather conditions, labor instability or regulatory oversight. The
Company's results of operations for interim periods are not necessarily
indicative of those for an entire year, because the travel business is subject
to seasonal fluctuations. Due to the greater demand for air travel during the
summer months, revenues in the airline travel industries in the second and third
quarters of the year tend to be greater than revenues in the first and fourth
quarters of the year.

         This discussion contains various forward-looking statements and
information that are based on management's beliefs as well as assumptions made
by and information currently available to management. When used in this
document, the words "anticipate", "estimate", "project", "expect" and similar
expressions are intended to identify forward-looking statements. Such statements
are subject to certain risks, uncertainties and assumptions. Should one or more
of these risks or uncertainties materialize, or should underlying assumptions
prove incorrect, actual results may vary materially from those anticipated,
estimated, projected or expected. Among the key factors that may have a direct
bearing on the Company's results are competitive practices in the airline and
travel industries generally and particularly in the Company's principal markets,
the ability of the Company to meet existing financial obligations in the event
of adverse industry or economic conditions or to obtain additional capital to
fund future commitments and expansion, the Company's relationship with employees
and the terms of future collective bargaining agreements and the impact of
current and future laws and governmental regulations affecting the airline and
travel industries and the Company's operations. For additional discussion of
such risks see "Business - Risk Factors," included in Item 1 of the Company's
Annual Report on Form 10-K for the year ended December 31, 1998 which is on file
with the Securities and Exchange Commission. Any forward-looking statements
speak only as of the date such statements are made.

ITEM 3.         QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISK SENSITIVE INSTRUMENTS

(a)   Commodity Price Risk

         As of March 31, 1999 the Company had entered into fixed price swap
transactions hedging approximately 43% of its projected 1999 fuel requirements
including 50% related to the second quarter, 35% related to the third quarter
and 37% related to the fourth quarter. The use of such swap transactions in the
Company's fuel hedging program could result in the Company not fully benefiting
from certain declines in jet fuel prices. At March 31, 1999 the Company
estimates that a 10% change in the price per gallon of jet fuel would have
changed the fair value of the existing swap contracts by $5.5 million.

         As of May 10, 1999 approximately 46% of AWA's 1999 fuel requirements
are hedged.

(c)      Interest Rate Risk

         The Company's exposure to interest rate risk relates primarily to its
variable rate long-term debt obligations. At March 31, 1999 the Company's
variable-rate long-term debt obligations represented approximately 16% of its
total long-term debt. If interest rates increased 10% in 1999, the impact on the
Company's results of operations would not be material.
