Northwest Airlines has signed a codeshare agreement
with Midwest Airlines for tickets purchased beginning Nov. 3 with
travel starting on Nov. 17, 2007.The first phase of the codeshare agreement will include
Northwest’s Hawaii-bound flights from Seattle, San Francisco and Los
Angeles with travel beginning on Midwest Airlines in Milwaukee, Omaha
and Kansas City. The Northwest-operated flights will also be
identified in reservations systems and airport flight displays by the
Midwest Airlines two-letter “YX” code.

  “This is just the first step in expanding the networks of both
carriers by opening up 250 city-pairs and more than a 1,000 new flight
options for customers,” said Nathaniel Pieper, Northwest’s vice
president - alliances. “Codesharing allows Northwest to offer our
customers the expanded reach of two airlines while enjoying the
convenience of a single ticket and check-in.”

  The new codeshare agreement augments the initial Northwest and
Midwest partnership, started in May 2006, when the carriers forged a
frequent flyer program, and formalizes the Memorandum of Understanding
the two carriers signed in May 2007.

  Members of Northwest’s WorldPerks and Midwest’s Midwest Miles
frequent flyer programs will continue to receive accrual and
redemption benefits on flights operated by both airlines.
