Alaska Airlines operates twice-weekly Boeing 737-700 combi aircraft passenger and cargo jet service from Anchorage. At present, flights operate each Wednesday and Saturday (weather permitting). Occasionally, extra seasonal flights are operated to meet the demand of the fishing season. The Adak Airport was historically served for many years by Reeve Aleutian Airways (RAA) with scheduled passenger flights to Anchorage operated with Lockheed L-188 Electra turboprop combi aircraft during the 1970s followed by Boeing 727-100 jet combi aircraft during the 1980s and 1990s.
