Quzhou Airport, also called Quzhou Air Base is a dual-use military and civil airport located 2.9 kilometers east of the city of Quzhou in Zhejiang Province, China. Originally only a military airfield for the People's Liberation Army Air Force, the airport was first expanded for use by American bombers during World War II, and was later occupied by Japanese troops. A small passenger terminal opened to commercial flights on 26 November 1993, though expanded commercial use of the airport has been hampered by continued heavy military presence due to the airport's proximity to the East China Sea and Taiwan Strait. Airlines operating out of Quzhou Airport generally operate medium to large narrow-body aircraft, such as the Boeing 737. Quzhou's commercial passenger terminal is unique in being separated from the airport's two aircraft bays by a lake, requiring passengers to walk across a lengthy causeway before boarding. The airport serves as the base of operations for regional carrier Quzhou Airlines.
