Northwest Airlink was the trade name of Northwest Airlines' regional airline service, which flew turboprop and regional jet aircraft from Northwest's domestic hubs in Minneapolis, Detroit, and Memphis. Service was primarily to small-to-medium-sized cities and towns where larger aircraft might not be economical to operate and also to larger markets to either provide additional capacity or more frequent flights than could be justified using mainline aircraft. Beginning in July 2009, the Northwest Airlink trade name was phased out, and replaced by the Delta Connection trade name for Delta Air Lines as part of the Delta/Northwest merger.
Since the Delta merger Compass is now owned by Trans States Holdings and Mesaba is owned by Pinnacle Airlines Corp.
Northwest Airlink service was operated using 34-seat Saab 340B turboprops and 50-seat CRJ200 aircraft in a single class of service. Mesaba Airlines and Compass Airlines also operated Bombardier CRJ-900s and Embraer E-175s, respectively. Both aircraft were operated in a 76-seat, two-class configuration.
Northwest Airlink previously operated Avro RJ85 jet aircraft in a 69-seat, two-class configuration before this aircraft type was retired from the fleet. Other aircraft operated in the past by Northwest Airlink included various commuter turboprops such as the British Aerospace BAe Jetstream 31, CASA 212 and Short 360.
