<PAGE>

Delaware corporation (the "Company"), as supplemented by Trust Supplement No.
2000-3C thereto dated November 2, 2000, between the Trustee and the Company
(collectively, the "Agreement"), 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 "8.39% US Airways Exchange Pass Through Certificate, Series
2000-3C" (herein called the "Certificates"). This Certificate is issued under
and is subject to the terms, provisions and conditions of the Agreement. By
virtue of its acceptance hereof, the Certificateholder of this Certificate
assents to and agrees to be bound by the provisions of the Agreement and the
Intercreditor Agreement. The property of the Trust includes certain Equipment
Notes and all rights of the Trust to receive any payments under the
Intercreditor Agreement and any Liquidity Facility (the "Trust Property"). Each
issue of the Equipment Notes is or will be secured by, among other things, a
security interest in aircraft leased to or owned by the Company.

         The Certificates represent Fractional Undivided Interests in the Trust
and the Trust Property, and have 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.

         Subject to and in accordance with the terns of the Agreement and the
Intercreditor Agreement, from funds then available to the Trustee, there will be
distributed on each March 1 and September 1 (a "Regular Distribution Date"),
commencing on March 1, 2001, 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 and the Intercreditor 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 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.

         Subject to the terms of the Intercreditor Agreement, any incremental
interest due to a Holder of this Certificate will be passed through to such
Holder on each Regular Distribution Date in the manner provided for in the
Agreement, as more fully set forth in the Agreement and this Certificate.


<PAGE>

         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 that with respect
to Certificates registered on the Record Date in the name of a Clearing Agency
(or its nominee), such distribution shall be made by wire transfer. 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 a direct 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 on the face hereof 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 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 minimum denominations of $1,000 Fractional Undivided Interest and
integral multiples thereof except that


<PAGE>

one Certificate may be issued 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.

         Each Certificateholder and Investor, by its acceptance of this
Certificate or a beneficial interest herein, agrees to treat the Trust as a
grantor trust for all U.S. federal, state and local income tax purposes.

         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.

         Any Person acquiring or accepting this Certificate or an interest
herein will, by such acquisition or acceptance, be deemed to have represented
and warranted that either: (i) the assets of an employee benefit plan subject to
Title I of the Employee Retirement Income Security Act of 1974, as amended
("ERISA"), or of a plan subject to Section 4975 of the Internal Revenue Code of
1986, as amended (the "Code"), have not been used to purchase this Certificate
or an interest herein or (ii) the purchase and holding of this Certificate or
interest herein are exempt from the prohibited transaction restrictions of ERISA
and the Code pursuant to one or more prohibited transaction statutory or
administrative exemptions.

         THE AGREEMENT AND THIS CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND THE OBLIGATIONS, RIGHTS
AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH
SUCH LAWS.

         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.
