Belfast International Airport (IATA: BFS, ICAO: EGAA) is an airport 11.5 NM (21.3 km) northwest of Belfast in Northern Ireland. Formerly known as Aldergrove Airport, after the nearby village of Aldergrove. In 2018, over 6.2 million passengers travelled through the airport, marking a 7.4% increase compared with 2017. It features flights to some European metropolitan and several leisure destinations as well as a seasonal route to Orlando in the United States. The site for the airport was established in 1917, when it was selected to be a Royal Flying Corps training establishment during the First World War. Civil traffic began in 1922, when flights were conducted to fly newspapers from Chester. The first scheduled passenger service was started in 1933 by the Scottish airline Midland & Scottish Air Ferries. A new terminal and apron were built, with the necessary passenger facilities, and the complex was opened by Queen Elizabeth, The Queen Mother on 28 October 1963. The first regular jet service to London–Gatwick started in 1966, and in 1968 Aer Lingus and BOAC introduced scheduled services to New York City via Shannon and Glasgow-Prestwick respectively.
Belfast International has a CAA Public Use Aerodrome Licence that allows flights for the public transport of passengers or for flying instruction. The airfield was previously shared with the Royal Air Force base RAF Aldergrove, which closed in 2008. The base is now known as Joint Helicopter Command Flying Station, Aldergrove, and both runways are now owned by the airport. The airport is owned and operated by VINCI Airports which was previously owned by ADC & HAS.
