Stanley Airport is used by internal flights and provides connections to British bases in Antarctica. It was opened by the Argentine Air Force on 15 November 1972 (previously, international flights were by seaplane from Comodoro Rivadavia). Flights to Argentina ended after the 1982 conflict. A weekly flight to Punta Arenas in Chile commenced in 1993, which now operates out of RAF Mount Pleasant. Scheduled passenger flights between the Mount Pleasant airfield and the UK are also operated twice a week by a civilian airline contractor on behalf of the Royal Air Force.
