Beijing Capital Airlines (Chinese: 首都航空; pinyin: Shǒudū Hángkōng), a subsidiary of Hainan Airlines, is an airline based in the Capital Airlines Building (首都航空大厦 Shǒudū Hángkōng Dàshà) at Beijing Capital Airport in Chaoyang District, Beijing, People's Republic of China.
The company was established in 1995 as Deer Jet Airlines (Chinese: 金鹿航空; pinyin: Jīnlù Hángkōng). In 1998, it began offering international services under the Deer Air branding. In October 2007, it received its first Airbus A319 and began returning the formerly operated Boeing 737s. Deer Jet began providing charter services in December 2008 using a fleet of A319s and corporate jets. The airline was authorized by the Civil Aviation Administration of China to operate scheduled air services in 2009.
Deer Jet Airlines was divided into two companies on May 4, 2010. While the charter operation has kept the Deer Jet branding, scheduled operations using Airbus aircraft were renamed Beijing Capital Airlines.
