FOR IMMEDIATE RELEASE

Mesa Air Group Reports 3rd Quarter 2005 Earnings

PHOENIX, July 27, 2005 – Mesa Air Group, Inc. (NASDAQ-MESA) today announced 3^rd quarter after tax earnings of $17.1 million on revenues of $298.6 million. Total operating revenues for the third quarter of 2005 increased $59.0 million, or 24.6%, primarily the result of year-over-year increases to our jet fleet. Net income and earnings per share for the 3^rd quarter were $17.1 million and 40 cents per share on a diluted basis (all amounts reported herein are after tax and all per share amounts reported hereafter are on a diluted basis), respectively, as compared to net income of $9.7 million or 23 cents per share for the same period of fiscal 2004. Pro forma net income for the quarter was $16.5 million, or 39 cents per share. Pro forma net income excluded net investment gains of $0.7 million. This compares to pro forma earnings of $10.8 million, or 25 cents per share for the comparable period of fiscal 2004.

Total Available Seat Miles (ASMs) for the third quarter of 2005 increased 21.9% from the third quarter of 2004, primarily as a result of an increase in the number of regional jets flown from 124 jets as of June 30, 2004 to 142 as of June 30, 2005. During the quarter, the Company took delivery of five 86-seat CRJ-900s for our America West Express operations. At June 30, 2005, Mesa’s fleet of regional jets was comprised of 92 50-seat regional jets, 15 70-seat regional jets and 35 86-seat regional jets (53 America West, 30 United and 59 US Airways). The Company is contractually committed to delivering to America West three 86-seat regional jets, two during the remainder of fiscal 2005 and the third in the first quarter of fiscal 2006. In addition to its regional jet fleet, Mesa operates 40 turboprops, including 16 37-seat DH8-200s (6 America West and 10 United) and 24 B1900s (9 Mesa and 15 US Airways).

As of June 30, 2005, the Company’s cash, marketable securities and debt investments were approximately $258.3 million, which includes $10.1 million of restricted cash.

“In spite of the difficult industry environment, we are pleased to have generated these results,” said Jonathan Ornstein, Mesa’s Chairman and CEO. “Our earnings demonstrate the success of our business model and reflect the commitment of our employees and the continued support of our airline partners. Furthermore, given the Company’s strong financial results and future prospects, we continue to believe our current share price represents a compelling value and we remained active with our share repurchase program, repurchasing over 1.1 million shares during the quarter.”

To supplement our consolidated financial statements presented in accordance with GAAP, the Company uses non-GAAP measures of pro forma net income and pro forma earnings per share, which are adjusted from our GAAP results as shown above. These non-GAAP adjustments are provided to enhance the user’s overall understanding of our current financial performance. We believe the non-GAAP results provide useful information to both management and investors by excluding certain charges and other amounts that we believe are not indicative of our core operating results. These non-GAAP measures are included to provide investors and management with an alternative method for assessing the Company’s operating results in a manner that is focused on the performance of the Company’s ongoing operations and to provide a more consistent basis for comparison between quarters. In addition, since we have historically reported pro forma results to the investment community, we believe the inclusion of non-GAAP numbers provides consistency in our financial reporting. These measures are not in accordance with or an alternative for, GAAP and may be different from pro forma measures used by other companies.

Amounts reported above for prior year pro forma earnings per share amounts have been restated to reflect the Company’s adoption of Emerging Issues Task Force Issue Number 04-8, “The Effect of Contingently Convertible Debt on Diluted Earnings Per Share.”
