Taipei Songshan Airport
It was the third busiest domestic airport after Taipei Songshan Airport and Kaohsiung Airport until the Taiwan High Speed Rail was inaugurated. With passenger numbers dropping significantly, 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.
