Robert E. Cohn Counsel for Republic Airline In c. d/b/a Midwest Airlines Hogan & Hartson LLP Columbia Square 555 Thirteenth Street, N.W. Washington, DC 20004

Dear Mr. Cohn:

This letter is to inform you that the Federal Aviation Admini stration (FAA) has granted your petition to extend exemption number 7370, as ame nded, subject to the limitations expressed in this document. It explains the basi s for the decision and describes its effect.

The Basis for Our Decision

By letter dated March 30, 2010, you petitioned th e FAA on behalf of Republic Airline Inc. d/b/a Midwest Airlines (Republic) for an exte nsion of exe mption number 7370, as amended. That exemption from 14 C.F.R. § 93.123 allowe d Midwest Airlines ( now Republic) to use exemption slot number 1497 at Ronald Reag an Washington National Airport (DCA) to augment its service from DCA to Milwaukee, Wisconsin.

The FAA originally granted exemption number 7370 to Midwest for a two-year period on October 19, 2000. The FAA subsequently granted a series of extensions of the exemption in December 2002, February 2005, August 2005, June 2007, and July 2009. In the absence of a further extension, exemption number 7370E would expire on September 30, 2010. Your March 2010 petition requests the FAA extend the exemption for two additional years. In your petition, you indicate that there has been no change in the conditions and reasons relative to public interest and safety that were the basis for granting the original exemption.

The FAA published a summary of th is petition for exemption in the Federal Register for comment. 75 Fed. Reg. 21387 (Apr. 23, 2010). The comment period closed on May 13, 2010, and the FAA received no comments.

AGC-10-208-E2

Our Decision

The FAA has determined that the justification for the issuance of exemption number 7370, as amended, remains valid and is in the public interest. The exemption is extended through September 30, 2012. If Republic elects to seek a further extension of the exemption, it should submit its petition, along w ith the reasons why the extension is in the public interest, on or before March 30, 2012. The FAA will publish that request for public comment to

ensure full consideration of th e public interest. Through the comment process, members of the public may state any reason why the FAA should extend exemption number 7370, reallocate the slot exemption to another ca rrier, or allow the exemption to expire.

Therefore, under the authority provided by 49 U.S.C. §§ 40113 and 44701, which the FAA Administrator has delegated to me, I grant your petition, subject to the amended conditions

and limitations listed below. The FAA ame nds paragraphs 2, 3, 4, and 6 to replace “Midwest” with “Republic”; paragraph 2 to direct Republic to c onfirm the scheduled operation and frequency with the FAA Slot Administration Office because Republic currently has operations under this exemption; and paragraph 5 to clarify the applicability of 14 C.F.R. part 93, subparts K and S.

Conditions and Limitations

1. The operation authorized by the grant of exemption may be conducted only in the 2100 hour. The FAA may adjust the time period if necessary for air traffic control or other operational purposes.

2. Republic must contact the F AA Slot Administration Office to confirm the scheduled operation and frequency under this exemption.

3. This slot may be utilized only by Republic.

4. This exemption will be rescinded if Repub lic discontinues scheduled operations at

DCA.

5. The operation authorized under this exempti on is not part of the pool of permanent slots at DCA. However, this operation, while in effect, is subject to the provisions of 14 C.F.R. part 93, subparts K and S, including the slot usage requirement, except that the authority may not be sold, le ased, or otherwise transferred.

6. Republic must report usage of this slot on ce it begins operations authorized herein.

7. This letter must be attached to, and is part of, exemption number 7370.3

The Effect of Our Decision

Our decision extends the term ination date of exemption number 7370, as amended, to September 30, 2012, unless sooner superseded or rescinded.

Sincerely,

/s/

James W. Whitlow Acting Chief Counsel
