EXPLANATORY NOTE

DEREGISTRATION OF SECURITIES

These Post-Effective Amendments (these “Post-Effective Amendments”) (i) relate to the following Registration Statements on Form S-8 (each, a “Registration Statement” and collectively, the “Registration Statements”) of Hawaiian Holdings Inc., a Delaware corporation (the “Registrant”), which were previously filed by the Registrant with the U.S. Securities and Exchange Commission (the “SEC”); and (ii) are being filed to deregister any and all securities that remain unsold or otherwise unissued as of the date hereof under each such Registration Statement.

On September 18, 2024, pursuant to the Agreement and Plan of Merger, dated as of December 2, 2023, by and among Alaska Air Group, Inc. (“Parent”), Marlin Acquisition Corp., a direct wholly owned subsidiary of Parent (“Merger Sub”), and the Registrant, Merger Sub merged with and into the Registrant, with the Registrant surviving as a wholly owned subsidiary of Parent (the “Merger”).

As a result of the Merger, the Registrant is terminating all offers and sales of its securities registered pursuant to the Registration Statements and deregistering the remaining shares of Common Stock (the “Shares”) registered but unsold as of the effective time of the Merger under the Registration Statements, if any. In accordance with an undertaking made by the Registrant in the Registration Statements to remove from registration, by means of a post-effective amendment, any of the Shares that had been registered for issuance under the Registration Statements that remain unsold at the termination of the offerings, the Registrant removes from registration any and all such Shares registered but unsold as of the date of these Post-Effective Amendments under the Registration Statements. The Registration Statements are amended, as appropriate, to reflect the deregistration of the Shares as of the date of these Post-Effective Amendments and the Registrant terminates the effectiveness of the Registration Statements.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused these Post-Effective Amendments to the Registration Statements to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Honolulu, State of Hawaii, on September 18, 2024.

Pursuant to Rule 478 under the Securities Act of 1933, as amended, no other person is required to sign these Post-Effective Amendments.
