Tainan Airport (Chinese: 臺南機場; formally "臺南航空站") (IATA: TNN, ICAO: RCNN) is a commercial airport located in South District, Tainan City, Taiwan. It is shared with Republic of China Air Force Tainan AFB. In January 2011, the Civil Aeronautics Administration approved the airport to handle international flights.
It is the third busiest domestic airport after Taipei Songshan Airport and Kaohsiung Airport. However its passenger numbers have dropped significantly since 2007 when the Taiwan High Speed Rail was inaugurated. Far Eastern Air Transport suspended its service between Tainan Airport and Taipei Songshan Airport on 1 March 2008, ending the carrier's 50-year service history at Tainan Airport. Its competitor, TransAsia Airways, also had to downgrade the aircraft it used from a jet (Airbus A320) to a turboprop (ATR 72) to maintain revenue, and finally decided to service through the airport as of 1 August 2008.
Because of the shared use with the Air Force, the airport terminal was built quite a distance away from the airfield. Passengers disembark at the apron and board shuttle buses to the terminal. The shared use with the Air Force also means some flights have to be cancelled when the Air Force conducts exercises.
A number of US units have been stationed at Tainan Air Base, including the 868th Tactical Missile Squadron from 1958 to 1962, which operated MGM-1 Matadors, probably under the ultimate control of the United States Taiwan Defense Command.
