Opened in 1976, Chiayi Airport was one of the airports in Taiwan that were severely affected by the opening of the Taiwan High Speed Rail in 2007. Uni Air is the sole operator of scheduled flights to the airport. Although listed as an international airport by the Taiwanese government, the joint use of Chiayi Airport's facilities by the Republic of China Air Force and the lack of complete customs and immigration facilities at the airport restricts the use of the airport by international flights. As such, the airport has no scheduled international flights; it is only served internationally by occasional chartered flights.
