Kangerlussuaq Airport (Greenlandic: Mittarfik Kangerlussuaq, Danish: Søndre Strømfjord Lufthavn) (IATA: SFJ, ICAO: BGSF) is an airport in Kangerlussuaq, a settlement in the Qeqqata municipality in central-western Greenland. Alongside Narsarsuaq Airport, it is one of only two civilian airports in Greenland large enough to handle large airliners. It is located away from the coast and hence less prone to fog and wind in comparison with other airports in Greenland.
In the mid 1950s, transatlantic civilian flights began using the air base for refueling. In 1956, Scandinavian Airlines (SAS) was flying "Polar route" service with three round trip flights per week being operated with Douglas DC-6B propliners on a routing of Copenhagen - Sondre Stromfjord (now Kangerlussuaq) - Winnipeg - Los Angeles. This use enabled air travel to Greenland, but fell off in the 1960s as airliners gained greater range. Instead the base became the hub of Greenland air traffic.
The airport was handed over to civilian Greenlandic control in 1992.
Kangerlussuaq Airport is the international hub for Air Greenland. The Kangerlussuaq area has very few inhabitants (around 500), so few passengers have their origin or destination here (some tourists and conference participants do that). Most passengers change planes.
