                                     WARRANT
                       TO PURCHASE SHARES OF COMMON STOCK
                                       OF
                         REPUBLIC AIRWAYS HOLDINGS, INC.




Date:  April 25, 2002


                  THIS IS TO CERTIFY THAT, for value received, AMR CORP., a
Delaware corporation ("AMR"), is entitled, subject to the terms herein, to
purchase from REPUBLIC AIRWAYS HOLDINGS INC., a Delaware corporation (the
"COMPANY"), at any time, or from time to time, the number of fully paid and
nonassessable shares set forth herein of the Company's common stock, $.001 par
value (the "COMMON STOCK"), at the Exercise Price (as defined below), all on the
terms and conditions and pursuant to the provisions hereinafter set forth. The
term "WARRANT SHARES," as used herein, refers to the shares of Common Stock
purchasable hereunder. As used herein, the term "HOLDER" shall initially mean
AMR, and shall subsequently mean each person or entity to whom this Warrant is
duly assigned.


         1. VESTING AND EXERCISE OF WARRANT; CANCELLATION OF PRIOR WARRANT.


                  (a) This Warrant shall be exercisable for vested Warrant
Shares commencing on the closing date (the "EFFECTIVE DATE") of the Company's
initial public offering of shares of Common Stock registered under the
Securities Act (the "IPO"). Warrant Shares constituting three and three quarters
percent (3.75%), subject to increase or decrease as provided herein, of the
Number of IPO Shares (as defined below) shall vest over a ten-year period (at
the rate of 10% on each anniversary of the Vesting Commencement Date (as defined
below), beginning on the first anniversary of the Vesting Commencement Date (the
"TEN-YEAR VESTING PERIOD"). The "VESTING COMMENCEMENT DATE" is June 11, 2001.
Warrant Shares constituting five percent (5%) of the Number of IPO Shares shall
vest over a five-year period (at the rate of 20% on each anniversary of the
Vesting Commencement Date), beginning on the fifth anniversary of the Vesting
Commencement Date (the "FIVE-YEAR VESTING PERIOD" and collectively with the
Ten-Year Vesting Period, the "VESTING PERIODS") (for any Warrant Share the
Holder elects to purchase hereunder, the date upon which such Warrant Share
vests is referred to herein as its "VESTING DATE"). A Warrant Share that has
vested may be purchased pursuant to this Warrant at the option of the Holder, in
whole or part, at any time between the Effective Date and the later of the fifth
anniversary of (a) the Effective Date or (b) its Vesting Date (with respect to a
Warrant Share, such time period is referred to herein as its "EXERCISE PERIOD").
Notwithstanding the foregoing and notwithstanding anything contained in this
Warrant to the contrary, no unvested Warrant Share shall continue to vest and
the option to purchase unvested Warrant Shares shall automatically expire upon
the earlier of (a) the date that the Holder issues notice to the Company to
terminate that certain Air Services Agreement, dated as of June 11, 2001, by and
between AMR and Airlines, Inc. ("CHAUTAUQUA"), as thereafter amended (the "AIR
SERVICES AGREEMENT") and (b) the date that the aggregate number of Committed
Aircraft that (i) are in service and (ii) are committed to be placed into
service under the Air Service Agreement and (iii) excluding any aircraft that
are removed from service under the Air Service Agreement pursuant to an
agreement between AMR or any Affiliate and the Company ("REMOVED AIRCRAFT"), is
less than ten.




                  (b) To the extent an increase in the Number of Committed
Aircraft as defined below after the Effective Date results in a corresponding
increase in the Applicable Percentage Shares (as defined below) and, thereby,
Warrant Shares, pursuant to SECTION 2 hereof, such additional Warrant Shares
shall be deemed to have been issuable on the Execution Date for purposes of
vesting, and shall vest over a ten-year period (at the rate of 10% on each
anniversary of the Execution Date), beginning on the first anniversary of the
Execution Date. Subject to the last sentence of this paragraph, to the extent
that the removal from service under the Air Service Agreement of one or more
Removed Aircraft results in a corresponding decrease in the Applicable
Percentage Shares and, thereby, Warrant Shares, pursuant to Section 2 hereof,
such reduced Warrant Shares shall be deemed to have been issuable on the
Execution Date for purposes of vesting, and shall vest over a ten-year period
(at the rate of 10% on each anniversary of the Execution Date), beginning on the
first anniversary of the Execution Date. Notwithstanding any provision hereof to
the contrary, if as a result of such decrease, on the date(s) of the events
giving rise to such decrease the Holder shall have exercised this Warrant for a
greater number of Warrant Shares than shall have vested, the vesting of
additional Warrant Shares shall be suspended until such time as the decreased
number of vested Warrant Shares is equivalent to the number of Warrant Shares as
to which the Holder shall have exercised this Warrant.


                  (c) This Warrant shall supercede and replace the Warrant to
purchase the common stock, $.01 par value, of Chautauqua dated June 11, 2001
(the "Prior Warrant"). Effective the date hereof, the Prior Warrant and all
rights conferred thereunder shall be cancelled and be of no further force and
effect.

         2. NUMBER OF WARRANT SHARES ISSUABLE. At any given time, the total
number of Warrant Shares issuable pursuant to this Warrant shall be determined
by multiplying the Applicable Percentage of IPO Shares (as defined below) by the
Number of IPO Shares (as defined below). The "NUMBER OF IPO SHARES" shall equal
the greater of (a) the number of shares of Common Stock registered under the
Securities Act, including any over allotment option granted to the underwriters
whether or not exercised, pursuant to the IPO or (b) sixty percent (60%) of the
number of shares of Common Stock outstanding immediately prior to the closing of
the IPO (such number of shares of Common Stock to be computed on a fully diluted
basis assuming the conversion or exchange of all securities of the Company
convertible or exchangeable, either directly or indirectly, into Common Stock
and the exercise of all options, warrants and rights exercisable, either
directly or indirectly, for Common Stock). The "Applicable Percentage of IPO
Shares" shall be equal to the percentage of IPO Shares corresponding to the
Number of Committed Aircraft (as defined below) as set forth on Schedule A
attached hereto. The Number of Committed Aircraft means the number of aircraft
at any given time committed to Feeder Air Service (as defined in the Air
Services Agreement), pursuant to the Air Services Agreement, including Firm
Approved Aircraft and Option Aircraft (as those terms are defined in the Air
Services Agreement) that AMR and any Affiliate (as defined in Rule 144
promulgated under the Securities Act) have committed to engage in Feeder Air
Service but that are not then in service, but excluding any Removed Aircraft.

         3. EXERCISE PRICE. The per share price at which the Warrant Shares may
be purchased shall equal ninety-three percent (93%) of the public offering price
per share of Common Stock as set forth on the cover page of the final prospectus
delivered in connection with the IPO (the "EXERCISE PRICE").

         4. MANNER OF EXERCISE; PAYMENT FOR SHARES; ISSUANCE OF CERTIFICATES;
DEFINITIONS.

                  (A) MANNER OF EXERCISE. Subject to the provisions of this
Warrant, the Warrant Shares may be purchased by the Holder, in whole or in part,
by the surrender of this Warrant together with a completed election to purchase
agreement in the form attached to this Warrant (the "ELECTION AGREEMENT"), to
the Company during normal business hours on any business day, during the
Exercise Period, at the Company's principal executive offices (or such other
office or agency of the Company as it may reasonably designate by notice to the
Holder), and upon payment to the Company of an amount of consideration equal to
the aggregate Exercise Price of the purchased Warrant Shares ("TOTAL PURCHASE
PRICE").


                  (B) PAYMENT FOR SHARES. The Total Purchase Price may be paid
(a) in cash, by certified or official bank check or by wire transfer for the
account of the Company (the "CASH EXERCISE"); (b) notwithstanding (a), if the
Fair Market Value (as defined below) of the Company's Common Stock is greater
than






the Exercise Price, in lieu of exercising this Warrant by payment of cash, the
Holder may elect to receive shares of Common Stock (the "CASHLESS EXERCISE")
computed as of the date of such calculation using the following formula:



                                    X=  Y(A-B)
                                        -------
                                                A


                  Where X = the number of shares of Common Stock to be issued to
                  the Holder


                  Y = the number of shares of Common Stock purchasable under the
                  Warrant or, if only a portion of the Warrant is being
                  exercised, the portion of the Warrant being exercised and
                  canceled
                  A = the Fair Market Value of one share of the Company's Common
                  Stock
                  B = the Exercise Price

         or (c) in any combination of the foregoing.

                  (C)      DEFINITIONS.

                           (i) "FAIR MARKET VALUE" shall mean, as of any date of
                  determination, with respect to any Common Stock, (x) if there
                  is a Qualified Public Market (as defined below) for such
                  Common Stock, the value per share determined pursuant to
                  clause (i) or (ii) below of this definition or (y) if there is
                  no such Qualified Public Market, the value determined pursuant
                  to clause (iii) below of this definition:


                                            (i) if such Common Stock is listed
                                    or quoted on a national securities exchange
                                    or admitted to unlisted trading privileges
                                    on such an exchange, the average last
                                    reported sale price (as reported in THE WALL
                                    STREET JOURNAL) of a share of such Common
                                    Stock over the 21 trading day period
                                    immediately prior to the date of
                                    determination or if no such sale is made on
                                    any such day, the mean of the closing bid
                                    and asked prices for such Common Stock on
                                    such day on such exchange; or


                                            (ii) if such Common Stock is not so
                                    listed or admitted to unlisted trading
                                    privileges, the average mean of the last bid
                                    and asked prices reported for a share of
                                    such Common Stock over the 21 trading day
                                    period immediately prior to the date of
                                    determination (A) by the National
                                    Association of Securities Dealers Automatic
                                    Quotation System or (B) if reports are
                                    unavailable under clause (A) above by the
                                    National Quotation Bureau Incorporated; or


                                            (iii) if such Common Stock is not so
                                    listed or admitted to unlisted trading
                                    privileges and bid and asked prices are not
                                    so reported, then the Company shall give
                                    prompt written notice to the Holder of the
                                    need to determine the Fair Market Value of
                                    such Common Stock, as well as a statement of
                                    the fair market value of such Common Stock
                                    determined by the Board of Directors of the
                                    Company. In such event, the Fair Market
                                    Value of such Common Stock shall be the fair
                                    market value per share agreed to by the
                                    Board




                                    of Directors of the Company and the
                                    Holder; PROVIDED, HOWEVER, if no such
                                    agreement is reached within thirty (30) days
                                    of the date on which the event for which the
                                    Fair Market Value is required to be
                                    determined occurs, then the Fair Market
                                    Value shall be determined as follows: the
                                    Company and the Holder shall each designate
                                    promptly in a written notice to the other
                                    its determination of the fair market value
                                    of such Common Stock as of the applicable
                                    reference date, and the Fair Market Value of
                                    such Common Stock as of the applicable
                                    reference date shall then be determined by a
                                    nationally recognized independent appraiser
                                    (the "INDEPENDENT FINANCIAL EXPERT")
                                    selected by the Holder from a group of three
                                    appraisers chosen by the Company (with whom
                                    the Company does not have an existing
                                    business relationship) and the Holder
                                    assuming an arm's-length private sale
                                    between a willing buyer and a willing
                                    seller, neither acting under compulsion. The
                                    determination by the Independent Financial
                                    Expert of the Fair Market Value shall be
                                    final and binding on the Company and the
                                    Holder. The costs and expenses of any such
                                    Independent Financial Expert making such
                                    valuation shall be paid by the Company,
                                    except that such expenses shall be borne
                                    solely by the Holder to the extent that the
                                    Independent Financial Expert concludes that
                                    the valuation of such Common Stock made by
                                    the Board of Directors of the Company is
                                    within ten percent (10%) of the Fair Market
                                    Value.


                           (ii) "QUALIFIED PUBLIC MARKET" shall mean with
                  respect to the Common Stock of the Company, an active trading
                  market on a national securities exchange or over-the-counter
                  market which consists of such publicly held Common Stock in
                  the Company, with a minimum market value of $10,000,000 for
                  such Common Stock. A "Qualified Public Market" shall be deemed
                  to exist if the financial parameters set forth in the
                  immediately preceding sentence have been met for the Common
                  Stock for a period of 21 consecutive days.


                  (D) ISSUANCE OF CERTIFICATES. The Warrant Shares so purchased
shall be deemed to be issued to the Holder, as the record owner of such shares,
as of the close of business on the date on which this Warrant shall have been
surrendered, the completed Election Agreement shall have been delivered, and
payment of the Total Purchase Price shall have been made as set forth above.
Certificates for the Warrant Shares so purchased shall be delivered to the
Holder within a reasonable time, not to exceed three (3) business days after
this Warrant shall have been so exercised. The certificates so delivered shall
be in such denominations as may be requested by the Holder and shall be
registered in the name of the Holder. If this Warrant should be exercised in
part only, the Company shall, upon surrender of this Warrant, execute and
deliver a new Warrant evidencing the rights of the Holder thereof to purchase
the balance of the Warrant Shares issuable hereunder.


         5. CERTAIN AGREEMENTS OF THE COMPANY. The Company hereby covenants and
agrees as follows:


                  (A) SHARES TO BE FULLY PAID. All Warrant Shares will, upon
issuance in accordance with the terms of this Warrant, be validly issued, fully
paid and nonassessable and free from all taxes, liens and charges with respect
to the issue thereof.


                  (B) RESERVATION OF SHARES. During the Exercise Period, the
Company shall at all times have authorized, and reserved for the purpose of
issuance upon exercise of this Warrant, a sufficient number of shares of Common
Stock to provide for the exercise of this Warrant.


                  (C) SUCCESSORS AND ASSIGNS. This Warrant will be binding upon
any entity succeeding to the Company by merger, consolidation or acquisition
of all or substantially all of the Company's assets.




         6. ADJUSTMENT TO THE NUMBER OF WARRANT SHARES. During the Exercise
Period, the number of Warrant Shares and the Exercise Price shall be subject to
adjustment from time to time as provided in this SECTION 6.

                  (A) SUBDIVISION OF COMMON STOCK. During the Exercise Period,
if the Company subdivides (by any stock split, stock dividend, recapitalization,
reorganization, reclassification or otherwise) any shares of Common Stock into a
greater number of shares, then, after the date of record for effecting such
subdivision, the number of shares of Common Stock issuable upon exercise of this
Warrant shall be proportionally increased so that the percentage of Warrant
Shares, after the subdivision, of the total number of shares of Common Stock
will be equal to the percentage of Warrant Shares, immediately prior to such
subdivision, of the total number of shares of Common Stock immediately prior to
such subdivision. In addition, the Exercise Price shall be proportionally
decreased to appropriately reflect such subdivision.


                  (B) CONSOLIDATION, MERGER OR SALE. During the Exercise Period,
in case of any consolidation of the Company with, or merger of the Company into
any other corporation, or in case of any sale or conveyance of all or
substantially all of the assets of the Company other than in connection with a
plan of complete liquidation of the Company, then as a condition of such
consolidation, merger or sale or conveyance, adequate provision will be made
whereby the Holder of this Warrant will have the right to acquire and receive
upon exercise of this Warrant in lieu of the shares of Common Stock immediately
theretofore acquirable upon the exercise of this Warrant, such shares of stock,
securities or assets as may be issued or payable with respect to or in exchange
for the number of shares of Common Stock immediately theretofore acquirable and
receivable upon exercise of this Warrant had such consolidation, merger or sale
or conveyance taken place. In any such case, the Company will make appropriate
provision to insure that the provisions of this SECTION 6 will thereafter be
applicable as nearly as may be in relation to any shares of stock or securities
thereafter deliverable upon the exercise of this Warrant.


         7. NO FRACTIONAL SHARES. No fractional shares of Common Stock are to be
issued upon the exercise of this Warrant. In lieu of delivering any fractional
shares to which the Holder would otherwise be entitled, the number of shares of
Common Stock shall be rounded to the nearest whole number.


         8. ISSUE TAX. The issuance of certificates for Warrant Shares upon the
exercise of this Warrant shall be made without charge to the Holder or such
shares for any issuance tax or other costs in respect thereof.


         9. NO RIGHTS OR LIABILITIES AS A SHAREHOLDER. This Warrant shall not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company. No provision of this Warrant, in the absence of affirmative action by
the Holder to purchase Warrant Shares, and no mere enumeration herein of the
rights or privileges of the Holder, shall give rise to any liability of such
Holder for the Exercise Price or as a shareholder of the Company, whether such
liability is asserted by the Company or by creditors of the Company.


         10. TRANSFER AND REPLACEMENT OF WARRANT.


                  (A) RESTRICTION ON TRANSFER. This Warrant and the rights
granted to the Holder are transferable, in whole or in part, upon surrender of
this Warrant, together with a properly executed assignment in the form attached
hereto, at the office of the Company referred to in SECTION 11 below; PROVIDED,
that any transfer or assignment shall be subject to the conditions set forth in
SUBSECTION 10(E). Until due presentment for registration of transfer on the
books of the Company, the Company may treat the registered Holder as the owner
and Holder of this Warrant for all purposes, and the Company shall not be
affected by any notice to the contrary.





                  (B) REPLACEMENT OF WARRANT. Upon receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction, or
mutilation of this Warrant and, in the case of any such loss, theft, or
destruction, upon delivery of an indemnity agreement reasonably satisfactory in
form and amount to the Company, or, in the case of any such mutilation, upon
surrender and cancellation of this Warrant, the Company, at its expense, will
execute and deliver, in lieu thereof, a new Warrant of like tenor.


                  (C) CANCELLATION; PAYMENT OF EXPENSES. Upon the surrender of
this Warrant in connection with any transfer or replacement as provided in this
SECTION 10, this Warrant shall be promptly canceled by the Company. The Company
shall pay all taxes and all other expenses (other than legal expenses, if any,
incurred by the Holder) in connection with the preparation, execution, and
delivery of Warrants pursuant to this SECTION 10.


                  (D) REGISTER. The Company shall maintain, at its principal
executive offices (or such other office of the Company as it may designate by
notice to the Holder), a register for this Warrant, in which the Company shall
record the name and address of the person or business entity in whose name this
Warrant has been issued, as well as the name and address of each transferee and
each prior owner of this Warrant.


                  (E) EXERCISE OR TRANSFER WITHOUT REGISTRATION. If, at the time
of the surrender of this Warrant in connection with any exercise, transfer, or
exchange of this Warrant, this Warrant (or in the case of any exercise, the
Warrant Shares issuable hereunder) shall not be registered under the Securities
Act, and under applicable state securities or blue sky laws, the Company may
require, as a condition of allowing such exercise, transfer, or exchange (i)
that the Holder or transferee of this Warrant, as the case may be, furnish to
the Company a written opinion of counsel, which opinion and counsel shall be
reasonably acceptable to the Company, to the effect that such exercise, transfer
or exchange may be made without registration under said Act and under applicable
state securities or blue sky laws, and (ii) that the Holder or transferee
execute and deliver to the Company an investment intent representation letter in
form and substance acceptable to the Company. AMR, as the initial Holder of this
Warrant, by taking and holding the same, represents to the Company that such
Holder is acquiring this Warrant for investment and not with a view to the
distribution thereof. Notwithstanding anything in this SUBSECTION 10(E) to the
contrary, the Company may transfer this Warrant to any Affiliate of the Company
without compliance with CLAUSE (I) of this SUBSECTION 10(E).


                  (F) LEGENDS.


                                    (i) Each Warrant Share (and each Warrant
                           Share issued to transferees of the Warrant), unless
                           and until such time as the same is no longer required
                           under the applicable requirements of the Securities
                           Act, or any applicable state securities laws, shall

                                    (ii) Each certificate or instrument (if any)
                           representing any Warrant Shares issued upon the
                           exercise of this Warrant (and each certificate or
                           instrument representing any Warrant Shares issued to
                           transferees of this Warrant or such certificate or
                           instrument), unless and until such time as the same
                           is no longer required under the applicable
                           requirements of the Securities Act, or any applicable
                           state securities laws, shall bear substantially the

                           THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY
                           NOT BE SOLD, PLEDGED, TRANSFERRED, ASSIGNED OR
                           OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH
                           REGISTRATION OR AN EXEMPTION THEREFROM UNDER THE
                           PROVISIONS OF THE SECURITIES ACT AND ANY APPLICABLE
                           STATE SECURITIES LAWS."


         11. NOTICES. All notices, requests and other communications required or

prepaid and addressed to the office of the Company at 2500 South High School

         12. GOVERNING LAW. THIS WARRANT SHALL BE GOVERNED AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS WITHOUT
REGARD TO THE CONFLICTS OF LAW.


         13.      MISCELLANEOUS.


                  (A) AMENDMENTS. This Warrant may only be amended by an
instrument signed by the Company and the Holder.


                  (B) DESCRIPTIVE HEADINGS. The descriptive headings of the
several paragraphs of this Warrant are inserted for purposes of reference only,
and shall not affect the meaning or construction of any of the provisions of
this Warrant.


                  (C) SEVERABILITY AND SAVINGS CLAUSE. If any one or more of the
provisions contained in this Agreement is for any reason (i) objected to,
contested or challenged by any court, government authority, agency,





department, commission or instrumentality of the United States or any state or
political subdivision thereof, or any securities industry self-regulatory
organization (collectively, "GOVERNMENTAL AUTHORITY"), or (ii) held to be
invalid, illegal or unenforceable in any respect, the Company and the Holder
agree to negotiate in good faith to modify such objected to, contested,
challenged, invalid, illegal or unenforceable provision. It is the intention of
the Company and the Holder that there shall be substituted for such objected to,
contested, challenged, invalid, illegal or unenforceable provision a provision
as similar to such provision as may be possible and yet be acceptable to any
objecting Governmental Authority and be valid, legal and enforceable. Further,
should any provisions of this Agreement ever be reformed or rewritten by a
judicial body, those provisions as rewritten will be binding, but only in that
jurisdiction, on the Holder and the Company as if contained in the original
Agreement. The invalidity, illegality or unenforceability of any one or more
provisions of this Warrant will not affect the validity and enforceability of
any other provisions of this Warrant.







         WITNESS the signature of a proper officer of the Company as of the date
first above written.
