March 1, 2012

To: David W. Lancelot

This letter agreement (this “Agreement”) is made by and between you and Spirit Airlines, Inc., a Delaware corporation (the “Company”), effective as of the eighth day following the date you sign this Agreement (the “Effective Date”) and constitutes the agreement between you and the Company regarding your resignation from employment with the Company.

A.    Termination Date

You acknowledge and agree that your status as an employee and officer of the Company will end effective as of March 1, 2012 (the “Termination Date”).

B.    Final Paycheck

As soon as administratively practicable following the Termination Date, the Company will pay you all accrued but unpaid base salary and all accrued and unused vacation earned through the Termination Date, subject to standard payroll deductions and withholdings. In addition, the Company will reimburse you for all outstanding expenses incurred prior to the Termination Date which are consistent with the Company's policies in effect from time to time with respect to travel, entertainment and other business expenses, subject to the Company's requirements with respect to reporting and documenting such expenses.

C.    Separation Benefits

As soon as administratively practicable after the Effective Date, subject to your return of all Company property pursuant to Section I below, you shall be entitled to the following:

You will be entitled to receive severance payments under the Spirit Airlines Executive Severance Plan Policy, a copy of which is attached. These payments (and the other payments described in this Agreement) are subject to all applicable federal (including social security), state and local taxes.

Payments will be reduced by any advances or similar outstanding amounts owed to Spirit, if any, such as sick days or vacation days used in excess of the number to which you were entitled as of your separation date. In addition, all legally and court-ordered garnishments and levies, if any, will be withheld.

Your payment(s) will be made semi-monthly according to regular payroll practices and subject to the foregoing provisions for the withholding of any federal, state and local taxes as well as any other payments or advances described above.

For the purposes of this Agreement, your base severance will be for a period of one (1) year at your base yearly salary of $291,011. This separation pay will be made in equal installments, consistent with past payroll practices. Payments will be made on current payroll pay dates, consisting of the 15^th and the last day of the month. Payments will be direct deposited.

In addition to the aforementioned severance pay, you will receive a 2011 bonus of $110,000 which also will be payable, together with the above-referenced base severance amounts, in equal installments and consistent with past payroll practices. Bonus payments will be made on current payroll pay dates, consisting of the 15^th and the last day of the month. Bonus payments will be direct deposited.

If you are later employed outside Spirit, you will not forfeit any base severance or bonus pay because of that employment.

Your eligibility to receive base severance pay, 2011 bonus and the other benefits provided to you hereunder is conditioned on your representation that you have conducted yourself in an ethical, forthright and honest manner in connection with your work for Spirit, as well as your compliance with the other undertakings set forth in this Agreement (including, without limitation, the release of claims set forth in Section D and the covenants set forth in Sections E, F and G). You agree that if you act contrary to the representations and obligations set forth in this Agreement, you may be obligated to pay Spirit an amount equal to the value of the consideration furnished under this Agreement, and that Spirit shall be entitled to immediately cancel any remaining severance or bonus payments owed to you.

You may apply for unemployment benefits upon termination. Any claim for these benefits will not be contested by Spirit. Separation pay can and must be disclosed to appropriate authorities. Treatment of separation pay from the beginning of eligibility for unemployment compensation may vary from state to state.

4.    Employee Assistance Program

The Company's Employee Assistance Program services will continue to be available for thirty (30) calendar days following your termination date. You may contact our EAP coordinator for more information. The EAP phone number is ###-###-####.

6.    Healthcare

You (and your spouse and dependants) shall be eligible for certain continued coverage under the terms of the Consolidated Omnibus Budget Reconciliation Act (Public Law 99-272, Title X, commonly known as “COBRA”). Company shall cover you (and your spouse and dependants) costs of coverage under COBRA at the same rate as if you remained a director with the Company for a period equal to the shorter of: (i) one (1) year or (ii) the date on which you accept a new position with another employer. If you obtain new employment within one year of your termination from Spirit, you must provide notification to Spirit, Attn : Thomas Canfield, SVP & General Counsel, 2800 Executive Way, Miramar, FL 33025).

7.    Blackberry

The Company will continue to pay for service on your Blackberry device for a period of thirty (30) days after your termination date. Thereafter, you may retain the device and your current telephone number at your expense.
