FIRST AMENDMENT TO RIGHTS AGREEMENT

This First Amendment, dated as of August 16, 2007 (this “Amendment”), to the
Rights Agreement, dated as of February 15, 2006 (the “Rights Agreement”), is
made between Midwest Air Group, Inc., a Wisconsin corporation (the “Company”),
and American Stock Transfer & Trust Company, a New York banking corporation (the
“Rights Agent”).  Capitalized terms not otherwise defined herein have the
meanings given to such terms in the Rights Agreement.

WHEREAS, the Company, Midwest Air Partners, LLC, a Delaware limited liability
company (“Parent”), and Midwest Acquisition Company, Inc., a Wisconsin
corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), have
proposed to enter into an Agreement and Plan of Merger (the “Merger Agreement”)
pursuant to which, among other things, Merger Sub will be merged into the
Company, with the Company being the surviving corporation (the “Merger”), and
each share of common stock, $.01 par value per share (the “Common Stock”), of
the Company outstanding immediately prior to the Effective Time (as defined in
the Merger Agreement), other than shares of the Common Stock (i) held in
treasury by the Company, or (ii) owned by Parent, Merger Sub or any other Parent
Subsidiary (as defined in the Merger Agreement), or (iii) owned by the Company
all of which shares shall cease to be outstanding and shall be converted into
the right to receive cash as provided in the Merger Agreement;

WHEREAS, the Board of Directors of the Company has approved and adopted the
Merger Agreement, determined that the Merger Agreement and the transactions
contemplated thereby, including the Merger, are advisable to, fair to and in the
best interests of the Company and its shareholders (other than Parent and Merger
Sub) and, in connection with the execution of the Merger Agreement, that it is
in the best interests of the Company and its shareholders to amend the Rights
Agreement;

WHEREAS, the Company and the Rights Agent desire to amend the Rights Agreement
to provide that neither Parent nor Merger Sub shall be deemed an Acquiring
Person, no Distribution Date shall be deemed to occur, and no Rights will
otherwise become exercisable as a result of the execution and delivery of the
Merger Agreement, the public announcement of such execution and delivery or the
consummation of the transactions contemplated by the Merger Agreement, including
the Merger; and

WHEREAS, pursuant to its authority under Section 27 of the Rights Agreement, the
Board of Directors of the Company has authorized and approved this First
Amendment to the Rights Agreement as of the date hereof.

NOW THEREFORE, in consideration of the premises and the mutual agreements herein
set forth in this Amendment, the parties hereby agree as follows:

1.

The Company hereby directs the Rights Agent, in its capacity as Rights Agent and
in accordance with Section 27 of the Rights Agreement, to execute this
Amendment.

2.

The Rights Agreement is hereby amended by adding a new Section 34 to the Rights
Agreement which shall read in its entirety as follows:

“Section 34.  Certain Exceptions.  Notwithstanding anything to the contrary
contained herein, (i) none of Midwest Air Partners, LLC, a Delaware limited
liability company (“Parent”), and Midwest Acquisition Company, Inc., a Wisconsin
corporation and a wholly-owned subsidiary of Parent (“Merger Sub”), nor any of
their respective Affiliates or Associates shall become, or be deemed to be,
individually or collectively, an Acquiring Person, a Beneficial Owner of Common
Shares or an Affiliate or Associate of an Acquiring Person by virtue of the
approval, execution and delivery of, the public announcement of such approval,
execution and delivery, or the performance of, the Agreement and Plan of Merger,
dated as of August ___, 2007, by and among Parent, Merger Sub and the Company
(as it may be amended from time to time, the “Merger Agreement”), or the
consummation of the Merger (as defined in the Merger Agreement) or the other
transactions contemplated by the Merger Agreement, (ii) no Section 11(a)(ii)
Event or Section 13 Event shall occur or be deemed to occur, in each case, as a
result of the approval, execution and delivery of, the public announcement of
such approval, execution and delivery, or the performance of, the Merger
Agreement, or the consummation of the Merger or the other transactions
contemplated by the Merger Agreement, and (iii) no Distribution Date shall
occur, in each case, as a result of the approval, execution and delivery of, the
public announcement of such approval, execution and delivery, or the performance
of, the Merger Agreement, or the consummation of the Merger or the other
transactions contemplated by the Merger Agreement.”

3.

This Amendment shall be deemed to be a contract made under the laws of the State
of Wisconsin and for all purposes shall be governed by and construed in
accordance with the laws thereof applicable to contracts to be made and
performed entirely within the State of Wisconsin.

4.

This Amendment shall be deemed effective immediately prior to the execution and
delivery of the Merger Agreement.  Except as otherwise amended hereby, the
Rights Agreement shall remain in full force and effect and shall be otherwise
unaffected hereby.

5.

This Amendment may be executed in counterparts and each of such counterparts
shall for all purposes be deemed to be an original, and both such counterparts
shall together constitute but one and the same instrument.
