                         AMENDMENT NO. 4 TO SCHEDULE 13D

         This is Amendment No. 4 (this "AMENDMENT") to the Schedule 13D filed by
the Reporting Parties with respect to the Common Stock (the "COMMON STOCK") of
Hawaiian Airlines, Inc. (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 18, 2002 (the "ORIGINAL SCHEDULE 13D").

ITEM 4   PURPOSE OF THE TRANSACTION.

         Item 4 is amended as follows:

         On May 2, 2002, the Company entered into an Agreement and Plan of
Merger, dated as of May 2, 2002 (the "HAWAIIAN MERGER AGREEMENT"), by and among
the Company, Hawaiian Holdings, Inc. ("HOLDINGS") and HA Sub Inc. ("HA SUB"), in
order to effect a reorganization of the Company into a holding company structure
whereby the Company will become a subsidiary of Holdings and the shareholders of
the Company will become shareholders of Holdings (the "REORGANIZATION").
Pursuant to the Hawaiian Merger Agreement, INTER ALIA, on the terms and subject
to the conditions set forth therein, (i) HA Sub will merge with and into the
Company, with the Company as the surviving corporation (the "HAWAIIAN MERGER"),
(ii) each share of Common Stock, together with the rights to purchase the
preferred stock of the Company attached thereto (other than such shares held by
a wholly owned subsidiary of Holdings pursuant to the AIP Merger Agreement (as
defined below)), will be converted into one share of Holdings common stock, and
(iii) each share of Holdings common stock held by the Company (being the 100
shares issued upon the formation of Holdings) will be canceled.

         After the completion of the Reorganization, each shareholder of
Holdings common stock will hold the same relative percentage of shares of
Holdings as such shareholder held of Common Stock immediately prior to the
Reorganization. In addition, Holdings will become a public company subject to
the reporting requirements of the Exchange Act of 1934 and will apply for its
shares of common stock to be listed on the American Stock Exchange and the
Pacific Exchange, and the Company will no longer be a public company subject to
the reporting requirements of the Exchange Act of 1934 and will cause its Common
Stock and preferred stock purchase rights to be delisted from the American Stock
Exchange and the Pacific Exchange.

         In connection with the Hawaiian Merger Agreement, AIP General Partner,
Inc. ("AIP GP"), the general partner of Airline Investors Partnership, L.P.
("AIP"), and AIP, Inc. ("AIP INC."), the sole limited partner of AIP, entered
into an Agreement and Plan of Merger, dated as of May 2, 2002 (the "AIP MERGER
Agreement"), with Holdings and AIP Merger Sub, Inc., a wholly owned subsidiary
of Holdings ("AIP MERGER SUB"), pursuant to which, INTER ALIA, on the terms and
subject to the conditions set forth therein, (i) the stockholders of each of AIP
GP and AIP Inc. will form a Delaware limited liability company ("AIP LLC") and
contribute all of the outstanding shares of capital stock of AIP GP and AIP
Inc., respectively, to AIP LLC in exchange for interests therein, (ii) AIP will
transfer its shares of Series B Special Preferred Stock, par value $.01 per
share, of the Company to John W. Adams, (iii) AIP GP will merge with and into
AIP Inc., with AIP Inc. as the surviving corporation (the "FIRST AIP MERGER"),
(iv) AIP Merger Sub will merge with and into AIP Inc., with AIP Inc. as the
surviving corporation (the "SECOND AIP MERGER" and together with the First AIP
Merger, the "AIP MERGERS"), and (v) AIP LLC will

have its shares of AIP Inc. common stock converted into Holdings common stock in
an amount equal to the number of shares of Common Stock held by AIP immediately
prior to the AIP Mergers.

         The foregoing discussion of the AIP Merger Agreement and the Hawaiian
Merger Agreement is qualified in its entirety by reference to each such
agreement filed as EXHIBIT 1 and EXHIBIT 2, respectively, to this Amendment and
incorporated by reference herein.

ITEM 6.  CONTRACTS, ARANGEMENTS, UNDERSTANDINGS OR
         RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

         Item 6 is hereby amended as follows:

         AIP has informed the Company that it intends to vote the shares of
Common Stock and the special preferred stock of the Company beneficially owned
by it in favor of the proposal to approve the Hawaiian Merger Agreement at the
2002 annual meeting of shareholders of the Company. In order for the Hawaiian
Merger Agreement to be approved by the shareholders of the Company, the
affirmative vote of holders of 75% of all issued and outstanding shares of
Common Stock and special preferred stock of the Company, voting together as a
single voting group, and the affirmative vote of holders of a majority of the
shares of the Company's special preferred stock represented at the meeting,
voting separately, is required. As of the date hereof, AIP beneficially owns
approximately 52.76% of the issued and outstanding shares of Common Stock and
four of the seven shares of Company's special preferred stock. The voting of all
of AIP's shares in favor of the Hawaiian Merger Agreement will assure the
necessary vote for the approval of the separate voting group comprised of the
holders of the Company's special preferred stock. The voting of all of AIP's
shares of Common Stock in favor of the Hawaiian Merger Agreement, however, is
insufficient to ensure that that the 75% voting requirement required under
Hawaii law will be satisfied.
