EXHIBIT 10.19

                   ALASKA AIR GROUP PERFORMANCE BASED PAY PLAN
              (formerly, the "Management Incentive Plan" or "MIP")

The Board of Directors (the "Board") of Alaska Air Group, Inc. (the "Company")
has adopted a plan to reward employees of Alaska Airlines, Inc. ("Alaska") and
Horizon Air Industries, Inc. ("Horizon"). The plan, formerly known as the
Management Incentive Plan, has been renamed as the Performance Based Pay Plan
("Plan"). This memorandum is provided to explain the key elements of how the
Plan will operate. The Performance Based Pay award ("Award") of each eligible
Participant will depend upon the degree to which the Company achieves the
performance goals set by the Compensation Committee of the Board for each
calendar year (a "Plan Year") and the discretion of the Compensation Committee
of the Board and Chief Executive Officer explained below. This Plan is effective
beginning with the 2003 Plan Year and each year thereafter until amended,
restated or terminated, pursuant to paragraph 8.

1.    ELIGIBILITY

      Eligibility to participate in the Plan during a Plan Year is limited to
      officers and other employees of Alaska and Horizon who (a) are designated
      by the Compensation Committee, and (b) are full-time employees of Alaska
      or Horizon as of the first day of January immediately following the end of
      the Plan Year, or (c) were full-time employees during the Plan Year and do
      not meet the requirement of (b) because their employment ended due to
      retirement at age 52 or older, disability or death (each a "Participant,"
      or collectively "Participants"). Individuals may become Participants
      during the Plan Year if they are newly hired or promoted during the year
      and meet the requirements of the preceding sentence. Participants who are
      on temporary medical leave, military leave, or otherwise not working
      either full-time or part-time for Alaska or Horizon for reasons approved
      by the Board, but who remain employed, also retain eligibility as
      Participants. Participation in the Plan does not guarantee that any Award
      will be paid if applicable performance goals specified for the Plan Year
      are not achieved for the year. An individual whose employment with Alaska
      or Horizon ends for any reason not described in (c) above, such as
      resignation or termination, forfeits eligibility upon such end of
      employment.

                                        1


2.    BASIS FOR PARTICIPATION

      A Participant's Basis for a Plan Year is used to determine the dollar
      amount of the Participant's Award for that year. The "Basis" is the actual
      Basic Salary of the Participant earned during the Plan Year multiplied by
      the percentage selected for that Participant by the Board. "Basic Salary"
      means the compensation earned by the Participant for services performed
      for Alaska or Horizon, INCLUDING amounts that the Participant could have
      received in cash had the Participant not elected to contribute the amount
      to an employee benefit plan maintained by Alaska, Horizon or the Company
      and any other voluntary payment the Participant makes which reduces
      his/her compensation (such as the Participant's voluntary contribution to
      an Internal Revenue Code ("Code") Section 401(k) Plan, Code Section 125
      medical account, dependent day care spending account, or charitable gift),
      but EXCLUDING commissions, all awards (including any Award under this
      Plan), and all other forms of incentive or other supplemental pay,
      employee benefits paid by the employer (such as employer contributions to
      a Code Section 401(k) Plan), cash and non-cash fringe benefits and
      perquisites (such as auto allowance and travel reimbursement).

3.    CALCULATION OF THE AWARD

      The size of the Award earned for a Plan Year will depend upon the extent
      to which the performance goals of the Company have been achieved during
      that Plan Year and the discretion of the Compensation Committee of the
      Board. Separate performance weighting has been established for each
      performance goal. The Award will equal the dollar amount achieved by
      multiplying the Participant's Basis by the sum of the weighted percentage
      achievement factors, as adjusted in the Compensation Committee's
      discretion pursuant to paragraph 6. All calculations will be performed by
      the Employee Services Department of Alaska and will be subject to approval
      solely by the Board. Once approved by the Compensation Committee of the
      Board, such calculations shall be conclusively presumed to be accurate.

                                        2


4.    PERFORMANCE WEIGHTING

      In order to achieve any Award for a particular performance goal, a
      "Threshold" must be achieved. A full entitlement is achieved when the
      "Target" is reached, and a double entitlement is possible if the "Maximum"
      is achieved. This weighting applies to each goal individually. Once the
      Threshold is achieved, the percentage of the difference between the
      Threshold and Target achieved is multiplied by the weighting factor as
      specified in the attachment for the applicable Plan Year. If the Target is
      exceeded, the percentage of the difference between the Target and the
      Maximum achieved is multiplied by the weighting factor as specified in the
      attachment for the applicable Plan Year. Since the difference between the
      Threshold and Target is, in most cases, arithmetically different from the
      difference between the Target and the Maximum, calculations will be
      performed utilizing either the Threshold-Target range, or Target-Maximum
      range, as applicable, to locate the percentage of the Target, or the
      percentage of the Maximum, as applicable, that has been achieved.

5.    PERFORMANCE GOALS AND APPLICABLE PERFORMANCE WEIGHTING FACTORS

      The Compensation Committee of the Board will establish the performance
      goals for each Plan Year during the life of this Plan, and will provide an
      annex to this Plan that outlines goals and the weighting factors. Each
      such attachment will be labeled "Performance Based Pay Plan Goals and
      Measures for (year)" and distributed to Eligible Participants.

6.    DISCRETIONARY FACTOR

      In the case of a Participant described in paragraph 1(c) who retired due
      to age, terminated employment due to disability, or died during the year,
      or a Participant who took a leave of absence or worked a reduced schedule
      during any portion of the year, the Compensation Committee of the Board
      retains absolute discretionary authority to adjust the Award to such
      Participant based upon the Compensation Committee's determination of such
      Participant's contribution to the Company.

                                        3


7.    TIMING OF AWARDS

      It is the intent of the Board to distribute the Award for a Plan Year no
      later than March 15 of the following year for each Plan Year that
      Participants have become entitled to an Award. A deceased Participant's
      Award will be paid to the beneficiary designated by the Participant for
      purposes of the Company's group term life insurance plan covering the
      deceased Participant, and in the absence of any designation, will be paid
      to the Participant's estate.

8.    AMENDMENT

      The Board, acting through the Compensation Committee, retains the right to
      modify the Plan in any manner that it deems appropriate, provided that it
      will not terminate the Plan for any Plan Year during that Plan Year unless
      it is clear that Participants will not receive an Award for that Plan
      Year. It is understood that the Compensation Committee of the Board will
      review the Plan yearly and may make changes to the Plan for the next Plan
      Year.

9.    MISCELLANEOUS

      a.    This memorandum, including its attachments, constitutes the entire
            understanding relating to an Award to any employee of Alaska or
            Horizon, and supersedes all prior oral or written agreements,
            representations or commitments relating to such Awards.

      b.    This Plan is not a commitment of the Company, Alaska or Horizon, to
            any officer or employee of such company, to continue that individual
            in its employ in order to qualify for an Award. Nothing contained in
            this Plan may be considered to be a promise of continued employment.
            Any employee who shall file suit against his or her employer for
            wrongful termination shall automatically cease to be a Participant.

      c.    In the event that a Participant has a written employment agreement
            with Alaska or Horizon which entitles such Participant to
            participate in the Management Incentive Plan, this Plan is intended,
            for the purpose of such agreements, to be considered to be the same
            plan and may continue to be referred to as the MIP.

                                        4


      d.    This memorandum and the rights and obligations provided for herein
            shall be construed and interpreted in accordance with the law of the
            state of Washington, excluding its conflicts of law rules.

      e.    No unpaid Award will be subject to the debts, liabilities, contracts
            or engagements of any Participant, and may not be alienated,
            pledged, garnished or sold, and any attempt to do so shall be void.
