Agreement"), between the Trustee and America West Airlines, Inc., a Delaware
corporation (the "Company"), as supplemented by Trust Supplement No. 1996-1C
thereto, dated as of November 26, 1996 (collectively, the "Agreement"), between
the Trustee and the Company, a summary of certain of the pertinent provisions of
which is set forth below. To the extent not otherwise defined herein, the
capitalized terms used herein have the meanings assigned to them in the
Agreement. This Certificate is one of the duly authorized Certificates
designated as "America West Airlines Pass Through Certificates, Series 1996-1C"
(herein called the "Certificates"). This Certificate is issued under and is
subject to the terms, provisions and conditions of the Agreement and the
Intercreditor Agreement, to which agreements the Certificateholder of this
Certificate by virtue of the acceptance hereof assents and by which such
Certificateholder is bound. The property of the Trust includes certain Equipment
Notes and all rights of the Trust to receive payments under the Intercreditor
Agreement and the Liquidity Facility (the "Trust Property"). Each issue of the
Equipment Notes is secured by a security interest in the Equipment leased to the
Company.

         Each of the Certificates represents a Fractional Undivided Interest in
the Trust and the Trust Property and has no rights, benefits or interest in
respect of any other separate trust established pursuant to the terms of the
Basic Agreement for any other series of certificates issued pursuant thereto.
The undivided percentage interest in the Trust represented by each of this
Certificate (as specified above) and the other America West Airlines Pass
Through Certificates, Series 1996-1C, was determined on the basis of (x) the
aggregate of the Reference Principal Amount of this Certificate (as specified
above) and of the other America West Airlines Pass Through Certificates, Series
1996-1C and (y) the aggregate original principal amounts of the Equipment Notes
constituting the Trust Property.

         Subject to and in accordance with the terms of the Agreement and the
Intercreditor Agreement, from funds then available to the Trustee, there will be
distributed on each January 2 and July 2 (a "Regular Distribution Date")
commencing January 2, 1997 to the Person in whose name this Certificate is
registered at the close of business on the 15th day preceding the Regular
Distribution Date, an amount in respect of the Scheduled Payments on the
Equipment Notes due on such Regular Distribution Date, the receipt of which has
been confirmed by the Trustee, equal to the product of the percentage interest
in the Trust evidenced by this Certificate and an amount equal to the sum of
such Scheduled Payments. Subject to and in accordance with the terms of the
Agreement, in the event that Special Payments on the Equipment Notes are
received by the Trustee, from funds then available to the Trustee, there shall
be distributed on the applicable Special Distribution Date, to the Person in
whose name this Certificate

                                                                               3


is registered at the close of business on the 15th day preceding the Special
Distribution Date, an amount in respect of such Special Payments on the
Equipment Notes, the receipt of which has been confirmed by the Trustee, equal
to the product of the percentage interest in the Trust evidenced by this
Certificate and an amount equal to the sum of such Special Payments so received.
If a Regular Distribution Date or Special Distribution Date is not a Business
Day, distribution shall be made on the immediately following Business Day with
the same force and effect as if made on such Regular Distribution Date or
Special Distribution Date and no interest shall accrue during the intervening
period. The Trustee shall mail notice of each Special Payment and the Special
Distribution Date therefor to the Certificateholder of this Certificate.

         Distributions on this Certificate will be made by the Trustee by check
mailed to the Person entitled thereto, without the presentation or surrender of
this Certificate or the making of any notation hereon. Except as otherwise
provided in the Agreement and notwithstanding the above, the final distribution
on this Certificate will be made after notice mailed by the Trustee of the
pendency of such distribution and only upon presentation and surrender of this
Certificate at the office or agency of the Trustee specified in such notice.

         The Certificates do not represent an obligation of, or an obligation
guaranteed by, or an interest in, the Company or the Trustee or any affiliate
thereof. The Certificates are limited in right of payment, all as more
specifically set forth herein and in the Agreement. All payments or
distributions made to Certificateholders under the Agreement shall be made only
from the Trust Property and only to the extent that the Trustee shall have
sufficient income or proceeds from the Trust Property to make such payments in
accordance with the terms of the Agreement. Each Certificateholder of this
Certificate, by its acceptance hereof, agrees that it will look solely to the
income and proceeds from the Trust Property to the extent available for
distribution to such Certificateholder as provided in the Agreement. This
Certificate does not purport to summarize the entire Agreement and reference is
made to the Agreement for information with respect to the interests, rights,
benefits, obligations, proceeds, and duties evidenced hereby. A copy of the
Agreement may be examined during normal business hours at the principal office
of the Trustee, and at such other places, if any, designated by the Trustee, by
any Certificateholder upon request.

         The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Certificateholders under the Agreement at any time
by the Company

and the Trustee with the consent of the Certificateholders holding Certificates
evidencing Fractional Undivided Interests aggregating not less than a majority
in interest in the Trust. Any such consent by the Certificateholder of this
Certificate shall be conclusive and binding on such Certificateholder and upon
all future Certificateholders of this Certificate and of any Certificate issued
upon the transfer hereof or in exchange hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Certificateholders of any of the Certificates.

         As provided in the Agreement and subject to certain limitations set
forth therein, the transfer of this Certificate is registrable in the Register
upon surrender of this Certificate for registration of transfer at the offices
or agencies maintained by the Trustee in its capacity as Registrar, or by any
successor Registrar, duly endorsed or accompanied by a written instrument of
transfer in form satisfactory to the Trustee and the Registrar, duly executed by
the Certificateholder hereof or such Certificateholder's attorney duly
authorized in writing, and thereupon one or more new Certificates of authorized
denominations evidencing the same aggregate Fractional Undivided Interest in the
Trust will be issued to the designated transferee or transferees.

         The Certificates are issuable only as registered Certificates without
coupons in denominations of $1,000 Fractional Undivided Interests and integral
multiples thereof, provided, that one Certificate may be in a different
denomination. As provided in the Agreement and subject to certain limitations
therein set forth, the Certificates are exchangeable for new Certificates of
authorized denominations evidencing the same aggregate Fractional Undivided
Interest in the Trust, as requested by the Certificateholder surrendering the
same.

         No service charge will be made for any such registration of transfer or
exchange, but the Trustee shall require payment of a sum sufficient to cover any
tax or governmental charge payable in connection therewith.

         The Trustee, the Registrar, and any agent of the Trustee or the
Registrar may treat the person in whose name this Certificate is registered as
the owner hereof for all purposes, and neither the Trustee, the Registrar, nor
any such agent shall be affected by any notice to the contrary.

         The obligations and responsibilities created by the Agreement and the
Trust created thereby shall terminate upon the distribution to
Certificateholders of all amounts required to be

distributed to them pursuant to the Agreement and the disposition of all
property held as part of the Trust Property.

         THE AGREEMENT AND THIS CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO
THE CONFLICT OF LAWS PROVISIONS OF THE STATE OF NEW YORK.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

                  IN WITNESS WHEREOF, the Trustee has caused this Certificate to
be duly executed.
