Ushuaia - Malvinas Argentinas International Airport — Ushuaia, Argentina

Ushuaia - Malvinas Argentinas International Airport carries the IATA code USH and holds the distinction of being one of the southernmost commercial airports on Earth, serving the city of Ushuaia in Argentina's Tierra del Fuego province. Perched dramatically between the Beagle Channel and the snow-capped Martial Mountains, USH functions as the principal gateway for Antarctic cruise expeditions, with thousands of travelers departing from here each austral summer to reach the White Continent. The airport's short runway juts into the channel waters, creating a striking approach for arriving flights. Beyond its polar tourism role, USH connects Ushuaia to Buenos Aires and other Argentine cities, supporting the remote region's fishing, tourism, and research communities.
