Uni Air
Service to Taichung and Chiayi was stopped in mid-2007 after the load factor dropped significantly due to Taiwan High Speed Rail start of revenue service in January 2007. Passenger volume decreased from 6.7 million in 2006 to 4.4 million in 2007 (a 34% decrease). Also due to the opening of the high speed rail line, on 1 March 2008, Uni Air suspended its service to Kaohsiung, while Far Eastern Air Transport suspended its service to Tainan. TransAsia Airways decided to stop flights to Tainan and Kaohsiung after 1 August 2008.
