EXPLANATORY NOTE

Spirit Airlines, Inc. (the “Company”) previously filed with the Securities and Exchange Commission (the “Commission”) (i) a Registration Statement on Form S-8 (File No. 333-206350) on August 13, 2015 (the “2015 Registration Statement”) to register 3,113,878 shares of common stock, par value $0.0001 per share, of the Company (“Common Stock”) for offer or sale under the Spirit Airlines, Inc. 2015 Incentive Award Plan (as amended and restated effective March 22, 2021, the “2015 Plan”), and (ii) a Registration Statement on Form S-8 (File No. 333-279999) on June 6, 2024 (such Registration Statement, together with the 2015 Registration Statement, the “Prior Registration Statements”) to register 3,200,000 shares of Common Stock for offer or sale under the 2015 Plan.

On June 7, 2024 (the “Effective Date”), the Company’s stockholders approved the Spirit Airlines, Inc. 2024 Incentive Award Plan (the “2024 Plan”) at the Company’s Annual Meeting of Stockholders. The 2024 Plan replaced and succeeded the 2015 Plan and, in connection therewith, no further awards will be made under the 2015 Plan as of and following the Effective Date. Pursuant to the terms of the 2024 Plan, the aggregate number of shares of Common Stock available for issuance under the 2024 Plan is (i) 2,200,000 shares of Common Stock newly authorized for issuance under the 2024 Plan (the “Newly Authorized Shares”), plus (ii) the number of shares of Common Stock that remained available for issuance under the 2015 Plan as of the Effective Date, plus (iii) the number of shares of Common Stock underlying any equity award previously granted under the 2015 Plan that become available for issuance again under the terms of the 2015 Plan upon the termination, forfeiture, repurchase, expiration or lapse of such award. As of the Effective Date, (a) a total of 1,475,754 shares of Common Stock previously registered under the Prior Registration Statements remained available for issuance under the 2015 Plan, and (b) a total of 2,873,234 shares of Common Stock previously registered under the Prior Registration Statements were subject to outstanding equity awards previously granted under the 2015 Plan (the shares described in (a) and (b), the “2015 Plan’s Shares”).

Accordingly, the Company is filing this Post-Effective Amendment No. 1 to each of the Prior Registration Statements (the “Post-Effective Amendment”) pursuant to SEC Compliance and Disclosure Interpretation 126.43 to amend the Prior Registration Statements to cover the issuance of the 2015 Plan’s Shares under the 2024 Plan (as such shares are no longer issuable under the 2015 Plan as of the Effective Date). The Company incorporates the contents of the Prior Registration Statements herein by reference, except to the extent supplemented, amended or superseded by the information set forth herein or the specific exhibits attached hereto.

For the avoidance of doubt, the Company is not registering any additional shares of Common Stock on this Post-Effective Amendment that were not previously registered on the Prior Registration Statements or that were not approved by the Company’s stockholders as of the Effective Date. Contemporaneously with the filing of this Post-Effective Amendment, the Company is filing a Registration Statement on Form S-8 to register the Newly Authorized Shares for offer or sale under the 2024 Plan.

Part I

The information specified in Item 1 and Item 2 of Part I of Form S-8 is omitted from this Registration Statement in accordance with Rule 428 under the Securities Act of 1933, as amended (the “Securities Act”) and the introductory note to Part I of Form S-8.

Not applicable.

Not applicable.

The Company is a Delaware corporation. Subsection (b)(7) of Section 102 of the Delaware General Corporation Law (the “DGCL”), enables a corporation in its original certificate of incorporation or an amendment thereto to eliminate or limit the personal liability of a director to the corporation or its stockholders for monetary damages for violations of the director’s fiduciary duty, except (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law; (iii) under Section 174 of the DGCL (providing for liability of directors for unlawful payment of dividends or unlawful stock purchases or redemptions); or (iv) for any transaction from which the director derived an improper personal benefit.

Section 145 of the DGCL authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities, including reimbursement for expenses incurred, arising under the Securities Act.

As permitted by Section 145 of the DGCL, the Company’s certificate of incorporation includes provisions that limit the personal liability of its directors for monetary damages and that provides for the indemnification of its directors, officers, employees and other agents to the fullest extent permitted under the DGCL.

In addition, as permitted by Section 145 of the DGCL, the bylaws of the Company provide that:

The Company has entered into separate indemnification agreements with its directors, officers and certain employees containing provisions which are in some respects broader than the specific indemnification provisions contained in the DGCL. With specified exceptions, these agreements provide for indemnification for related expenses including, among other things, attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding. The Company intends to enter into indemnification agreements with new directors, officers and other employees in the future as determined by its board of directors.

The indemnification provisions of the indemnification agreements entered into, or to be entered into, between the Company and its directors may be sufficiently broad to permit indemnification of the Company’s directors against certain liabilities that may arise by reason of their status or service as directors and to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified.

Not applicable.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to the Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing Fee Tables” or the “Calculation of Registration Fee” table, as applicable, in the effective Registration Statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the Registration Statement is on Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(h) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Re: Post-Effective Amendment No. 1 to Registration Statements on Form S-8 of Spirit Airlines, Inc.

Ladies and Gentlemen:

We have acted as counsel to Spirit Airlines, Inc., a Delaware corporation (the “Company”), in connection with the preparation of a Post-Effective Amendment No. 1 (the “Post-Effective Amendment”) to Registration Statements on Form S-8 (File No. 333-206350 and File No. 333-279999) (the “Prior Registration Statements”), which the Company is filing with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”) with respect to certain shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), issuable pursuant to the Spirit Airlines, Inc. 2024 Incentive Award Plan (the “2024 Plan”), such shares of Common Stock having originally been authorized for issuance under the Spirit Airlines, Inc. 2015 Incentive Award Plan (as amended and restated effective March 22, 2021, the “2015 Plan”) pursuant to the Prior Registration Statements.

On June 7, 2024 (the “Effective Date”), the Company’s stockholders approved the 2024 Plan, which replaced and succeeded the 2015 Plan. The aggregate number of shares of Common Stock available for issuance under the 2024 Plan is (i) 2,200,000 shares of Common Stock newly authorized for issuance under the 2024 Plan, plus (ii) the number of shares of Common Stock that remained available for issuance under the 2015 Plan as of the Effective Date, plus (iii) the number of shares of Common Stock underlying any equity award previously granted under the 2015 Plan that become available for issuance again under the terms of the 2015 Plan upon the termination, forfeiture, repurchase, expiration or lapse of such award. As of the Effective Date, (a) a total of 1,475,754 shares of Common Stock previously registered under the Prior Registration Statements remained available for issuance under the 2015 Plan and (b) a total of 2,873,234 shares of Common Stock previously registered under the Prior Registration Statements were subject to outstanding equity awards previously granted under the 2015 Plan, and, in each case, could be carried over from the 2015 Plan to the 2024 Plan for issuance under the 2024 Plan (the shares described in (a) and (b), the “2015 Plan’s Shares”).

We have examined the originals, or copies certified or otherwise identified to our satisfaction, of the 2024 Plan and such other corporate records, documents, certificates or other instruments as in our judgment are necessary or appropriate to enable us to render the opinion set forth below. In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to originals of all documents submitted to us as copies thereof and the authenticity of the originals of such latter documentation.

Based on the foregoing, we are of the opinion that, as of the date hereof, the 2015 Plan’s Shares that may be issued pursuant to the 2024 Plan have been duly authorized and, when issued in accordance with the terms of the 2024 Plan, will be validly issued, fully paid and non-assessable.

We hereby consent to the filing of this opinion as an exhibit to the Company’s Post-Effective Amendment. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act, or the rules and regulations of the Securities and Exchange Commission promulgated thereunder.

We are members of the bar of the State of New York. We express no opinion as to the laws of any jurisdiction other than the laws of the State of Delaware as currently in effect.

Exhibit 23.1

Consent of Independent Registered Public Accounting Firm

We consent to the incorporation by reference in the Registration Statement (Form S-8) pertaining to the Spirit Airlines, Inc. 2015 Incentive Award Plan and Spirit Airlines, Inc. 2024 Incentive Award Plan of our reports dated February 9, 2024, with respect to the consolidated financial statements of Spirit Airlines, Inc. and the effectiveness of internal control over financial reporting of Spirit Airlines, Inc. included in its Annual Report (Form 10-K) for the year ended December 31, 2023, filed with the Securities and Exchange Commission.
