Introduction
Northwest Airlines was a major airline in the United States with a history dating back to the 1920s. Known for its extensive network and distinct aircraft liveries, Northwest played a significant role in aviation history before merging with Delta Air Lines in the late 2000s.
History: From Airmail to Northwest Orient
Established in 1926 as Northwest Airways, the airline initially focused on airmail routes between Minneapolis and Chicago. It began carrying passengers in the 1930s and officially became Northwest Airlines in 1934. Post-World War II, Northwest expanded its routes significantly across the Pacific and rebranded as Northwest Orient Airlines in 1947. The airline built a strong presence in Asia, maintaining this focus until the company’s end in the 2000s.
Fleet Evolution: Classic Airliners

- Early passenger aircraft included the Douglas DC-3.
- Postwar long-haul flights featured the Boeing Stratocruiser.
- The jet age saw the introduction of the Douglas DC-8 and Boeing 707.
- The Boeing 747 and its later 747-400 model were flagship aircraft for transpacific flights.
- The widebody DC-10 was a staple for both domestic and international routes.
- The iconic Douglas DC-9 became a defining aircraft for Northwest’s domestic network, continuing in service post-merger with Delta Air Lines until 2014.
Distinctive Liveries Over the Years
Northwest’s aircraft were known for unique liveries:
- The Northwest Orient era featured a bare-metal fuselage with a red tail and bold titles.
- The 1970s livery included a dark-blue cheatline and a red tail.
- During the 1980s, aircraft donned a red tail with white and blue cheatlines.
- The 1989 introduced “bowling shoe” livery featured a red tail with a compass ‘N’ logo.
- Early 2000s saw a modern silver and grey fuselage with the stylized ‘nwa’ logo.
Merger with Delta Air Lines
Facing financial difficulties, Northwest filed for bankruptcy in 2005 and was later part of industry consolidation. In 2008, Northwest merged with Delta Air Lines, forming the largest airline. By 2010, the Northwest brand phased out, with Delta integrating its aircraft, staff, and routes. The merger strengthened Delta’s presence, particularly in Asia and the Midwest, and saw the reintroduction of the DC-9 to Delta’s fleet.
Northwest’s Legacy
Though Northwest Airlines no longer operates, its impact on U.S. aviation is evident through its pioneering routes and contributions to Delta’s global operations. Aviation enthusiasts can still spot former Northwest aircraft within Delta’s fleet, identifiable by registration numbers ending in NW or NB. Former Northwest DC-9 and 747-400 aircraft are displayed at the Delta Flight Museum.
