Northwest Airlines has announced that it will expand its service between its
WorldGateway at Detroit and Frankfurt during the peak summer season by
adding a second daily nonstop flight on the route beginning May 7,
2007 through October 27, 2007.The additional Detroit-Frankfurt service is part of Northwest’s
trans-Atlantic expansion in cooperation with joint venture partner KLM
Royal Dutch Airlines.

  In addition to the new Detroit-Frankfurt frequency and recently
announced Detroit-Dusseldorf service, scheduled to begin June 5, 2007,
Northwest/KLM serve 11 cities throughout Germany from the carriers
Amsterdam hub, including Berlin, Bremen, Cologne, Dusseldorf,
Frankfurt, Hamburg, Hannover, Munich, Munster/Osnabruck, Nuremberg and
Stuttgart.

  “With a second Detroit-Frankfurt daily flight, our customers will
now have greater flexibility and convenience when traveling to this
key German business city,” said Phil Haan, executive vice president -
international, alliances and information technology and chairman of
NWA Cargo. “The additional frequency is an integral part of our
trans-Atlantic expansion plan utilizing our 757 aircraft, which
includes service to two new European destinations.”

  As previously announced, Northwest/KLM will launch new
Detroit-Brussels service beginning on June 15, 2007 and
Hartford-Amsterdam service starting July 1, 2007, making Hartford,
Conn., Northwest/KLM’s 18th gateway to Europe. The trans-Atlantic
expansion effort also includes new frequencies between Detroit and
Amsterdam, beginning July 1, 2007, and a second daily flight between
Amsterdam and Boston, beginning July 15, 2007.

  Northwest’s new trans-Atlantic flights will be operated with
Boeing 757-200 aircraft. The aircraft are being fitted with
“winglets,” or extensions of the aircraft wing, that improve the fuel
efficiency of the 757 and in doing so, also extend its range.

  Inside the aircraft, Northwest is making several improvements to
the fleet dedicated to this new service in order to provide
trans-Atlantic customers with a comfortable travel experience.

  The World Business Class cabin will be configured with 16 new
seats in a two-aisle-two arrangement. The World Business Class seat
will provide five feet (1.5 meters) of personal space. The seat will
have many features including a four-way movable headrest, a laptop
computer power port, snake reading light, extendable foot rest and
lumbar support, among other comforts.

  World Business Class customers will be provided with a portable
in-flight entertainment system with a wide variety of movies,
short-subject videos, music programs, compact discs of music and games
to choose from, all available on-demand, so they can choose and play
their entertainment when it fits their needs.

  The coach class cabin will be equipped with 144 seats configured
in a three-aisle-three arrangement. The “pitch,” or distance between
rows, is being increased up to four inches, providing additional
legroom and comfort.

  The second Detroit-Frankfurt frequency is subject to slot approval
from Airport Coordination Germany. All of Northwest’s new European
