                         AMENDMENT NO. 9 TO SCHEDULE 13D

     This is Amendment No. 9 (this "Amendment") to the Schedule 13D filed by the
reporting persons listed above with respect to the Common Stock, par value $.01
per share (the "Common Stock"), of Hawaiian Holdings, Inc., a Delaware
corporation (the "Company"), dated as of January 18, 1996, as amended by
Amendment No. 1, dated as of January 31, 1996, as amended by Amendment No. 2,
dated as of December 19, 2001, as amended by Amendment No. 3, dated as of April
22, 2002, as amended by Amendment No. 4, dated as of May 7, 2002, as amended by
Amendment No. 5, dated as of May 31, 2002, as amended by Amendment No. 6, dated
as of July 11, 2002, as amended by Amendment No. 7, dated as of September 9,
2002, and as amended by Amendment No. 8, dated as of March 5, 2004 (the
"Original Schedule 13D").

     This Amendment should be read in conjunction with, and is qualified in its
entirety by reference to, the Original Schedule 13D and the applicable exhibits
thereto. Except as disclosed in and amended by this Amendment, all information
set forth in the Original Schedule 13D is unaffected hereby.

     Item 4 of the Original Schedule 13D is hereby supplemented by the
following:

Item 4.   Purpose of Transaction.

     As previously disclosed in the Company's Current Report on Form 8-K filed
on March 21, 2003, the Company's Form 12b-25 filed on March 21, 2003, and the
Company's Form 12b-25 filed on April 30, 2003, on March 21, 2003 Hawaiian
Airlines, Inc. ("Hawaiian Airlines"), the sole operating subsidiary of the
Company, filed a voluntary petition for reorganization under Chapter 11 of the
United States Bankruptcy Code in the United States Bankruptcy Court for the
District of Hawaii (the "Bankruptcy Court") (Case No. 03-00827).

     Also, as previously disclosed in the Original Schedule 13D, on March 1,
2004 the Company and AIP, LLC filed a preliminary plan of reorganization (the
"Proposed HHI Plan") with the Bankruptcy Court that proposes to recapitalize and
reorganize Hawaiian Airlines. The Company also issued a press release on March
1, 2004 relating to the Proposed HHI Plan. The Proposed HHI Plan is subject to
approval and confirmation by the Bankruptcy Court and Hawaiian Airlines'
creditors.

     On March 23, 2004, the Company announced that John W. Adams, the Company's
Chairman and Chief Executive Officer, and certain of his affiliates had entered
into an arrangement with Mr. Donald J. Carty pursuant to which Mr. Carty would
partially fund and manage an entity (the "New Investor") to be formed for the
purpose of holding a portion of the common stock of the reorganized Hawaiian
Airlines in furtherance of the Proposed HHI Plan. As the manager of the New
Investor, Mr. Carty would have the sole power to vote or direct the voting of
the shares of the reorganized Hawaiian Airlines held by the New Investor, Mr.
Adams, or his affiliates. In addition, if the Proposed HHI Plan were confirmed
by the Bankruptcy Court, the arrangement contemplates that AIP, LLC would
contribute to the New Investor shares of the




reorganized Hawaiian Airlines that it may hold, in exchange for a proportionate
interest in the New Investor. Under the arrangement, the parties would use
commercially reasonable efforts to amend the Proposed HHI Plan as necessary to
provide that Mr. Carty would assume the position of Chairman of the Board of the
reorganized Hawaiian Airlines. Mr. Carty is the former Chairman and Chief
Executive Officer of AMR Corp., the parent company of American Airlines, Inc.

Item 7.   Material to be Filed as Exhibits.

                                                            Not applicable/None.

     After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.
