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.
The first airport was built here during the US occupation in 1941 under the name of Bluie West-8, later renamed Sondrestromfjord Air Base and Sondrestrom Air Base.
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.
