Uni Air
However, in 1999, the number of services to Chiayi Airport decreased when Formosa Airlines withdrew from its operations at Chiayi Airport in the aftermath of an air crash over Hsinchu. This was followed by the successive withdrawals of Far Eastern Air Transport and TransAsia Airways in 2001 and 2002 respectively due to poor load factors caused by a slowing local economy. These withdraws left Uni Air, the successor of Great China Air, as the only operator of flights at Chiayi Airport.
