Air Changan (simplified Chinese: 长安航空; traditional Chinese: 長安航空; pinyin: Cháng'ān Hángkōng) is a Chinese domestic airline. Its main operating base is Xi'an Xianyang International Airport, serving several cities in Shaanxi Province. Initially an independent carrier, Air Changan merged with Hainan Airlines in 2000 and was later absorbed into that airline. Air Changan resumed service as an independent airline in May 2016, providing flights to four Chinese cities with three Boeing 737-800 aircraft.

In order to develop the local economy and aviation industry, in September 1990, the Shaanxi provincial government and local aircraft manufacturers began planning for a local airline, to operate with three Xian Y-7 aircraft. On 2 March 1992, the provincial government named the airline as Air Changan. On 11 April 1992, Air Changan was formally founded, merging Dapeng Airlines in to the new entity. On 5 January 1993, the first flight of Air Changan operated, from Xi'an to Yulin. Then was transfer to be operated by the provincial government only, after the aircraft manufacturers left the venture due to new regulations coming into effect.^{[citation needed]}

On 30 August 2000, Air Changan was purchased by Hainan Airlines (HNA) and renamed Chang An Airlines. On 1 July 2002, the first Boeing 737-400 was put into operation. In October 2002, Chang An Airlines, Xinhua Airlines and Shanxi Airlines were merged into Hainan Airlines.^{[citation needed]}

In December 2015, HNA Group began talks with the Shaanxi provincial government regarding the restoration of Chang An Airlines as an independent carrier.
