     Effective December 31, 2007, the Mileage Plus, Inc. Investment Plus Plan (the “MPI Plan”) was merged into the United Airlines Management and Administrative 401(k) Plan (the “SAM Plan”). As a result, the MPI Plan ceased to exist and the interests in the MPI Plan, which previously constituted securities registered pursuant to the Securities Act of 1933, as amended, no longer exist. Pursuant to Rule 15d-6, the SAM Plan has filed this Form 15 as successor in interest to the MPI Plan to reflect the suspension of the MPI Plan’s duty to file reports under Section 15(d) of the Securities Exchange Act of 1934, as amended.

 

 

     Pursuant to the requirements of the Securities Exchange Act of 1934, as amended, the United Airlines Management and Administrative 401(k) Plan, as successor to the Mileage Plus, Inc. Investment Plus Plan, has caused this certification/notice to be signed on its behalf by the undersigned duly authorized person.
