Memorandum of Understanding with Airbus

On November 15, 2011, Spirit Airlines, Inc. (the “Company”) jointly announced with Airbus that it had entered into a Memorandum of Understanding (“MOU”) for a significant addition to the Company’s existing aircraft purchase order with Airbus. The MOU, which is non-binding, contemplates an order of 75 A320 family aircraft, consisting of 30 of the existing aircraft model and 45 A320 NEO (New Engine Option) aircraft. These aircraft are in addition to the 33 aircraft not yet delivered under the Company’s existing order and would be scheduled for delivery from 2016 through 2021. The new aircraft would provide for growth capacity as well as capacity to replace the 28 aircraft in the Company’s present fleet with lease expirations between 2017 and 2020. The order outlined in the MOU is subject to a number of conditions, including the negotiation of definitive documentation and corporate approvals by both the Company and Airbus.

A copy of the press release regarding this announcement is attached hereto as Exhibit 99.1 and incorporated by reference herein.

Forward-Looking Statements

This report includes forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, including statements regarding the future order of aircraft as outlined above under the MOU. The Company has based these forward-looking statements largely on its current expectations and projections about future events and financial trends affecting the financial condition of its business. The words “contemplates,” “believe,” “may,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “predict,” “potential” and similar expressions, as they relate to the company, its business and its management, are intended to identify forward-looking statements. Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved. Forward-looking statements are based on information available at the time those statements are made and/or management’s belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements, including the ability of the Company and Airbus to successfully negotiate definitive documentation as contemplated by the MOU and obtain the necessary corporate approvals with respect to such documentation, as well as the “Risk Factors” included in the Company’s most recent Quarterly Report on Form 10-Q. In light of these risks and uncertainties, the forward-looking events and circumstances discussed in this report may not occur and actual results could differ materially from those anticipated or implied in the forward-looking statements.

All forward-looking statements attributable to the Company are expressly qualified in their entirety by the cautionary statements set forth above. Forward-looking statements speak only as of the date of this report. You should not put undue reliance on any forward-looking statements. The Company assumes no obligation to update forward-looking statements to reflect actual results, changes in assumptions or changes in other factors affecting forward-looking information, except to the extent required by applicable law.
