Kangerlussuaq International Airport — Kangerlussuaq, Greenland

Kangerlussuaq International Airport has historically served as Greenland's principal aviation hub, owing largely to its origins as a former United States military airbase constructed during World War II. Located at the head of a long fjord in western Greenland, SFJ benefits from a stable climate favorable to aviation and possesses one of Greenland's longest runways, enabling it to accommodate larger aircraft than most other airports on the island. For decades, Kangerlussuaq functioned as the primary gateway for international flights before onward connections to other Greenlandic settlements. The airport's strategic Cold War-era origins and continued aviation importance make it a distinctive feature of Greenland's transportation infrastructure, even as newer airports have begun to reshape international access to the island.
