Hualien Airport (花蓮機場) (IATA: HUN, ICAO: RCYU) is a commercial airport located in a 11.5 hectare civilian area of a military airbase in Hualien, Taiwan. It primary serves domestic flights although it can handle international charter flights as well. The proximity of Hualien Airport to a military base has caused some tension between travelers, airline officials, and the Republic of China Air Force, especially when civilian flights are cancelled due to war games exercises.
