Tiree Airport (Gael: Port Adhair Thiriodh) is located at Crossapoll on the island of Tiree. It is operated by the government-owned Highland and Islands Airports Limited and has the International Air Transport Association (IATA) location code "TRE". Scheduled air services operate to Glasgow.
The first air service to Tiree began on the 1st July, 1936, landing on a grass airstrip on the site of the present-day airport. In 1940, the Air Ministry began building an airfield for the Royal Air Force. During World War II, Tiree was used as a base for protecting the North Atlantic convoys through anti-submarine patrols, in addition to air-sea rescue missions and meteorological flights. The airfield reverted to civilian use following the war. There are now three runways and many remnants of the airport's wartime heritage can still be found, including concrete bases of former hangars, aircraft stands, taxi-ways and military buildings.
