Grand China Air (GCA) is a new airline formed on 29 November 2007 under the initiative of the HNA group's largest operational entity, Hainan Airlines, to merge its operations with HNA Group subsidiaries Shanxi Airlines, Chang'an Airlines, and China Xinhua Airlines. Headquartered in Beijing and registered in Hainan Province, it began with three Boeing 737-800s, but when the merger is complete, the airline's fleet will exceed 250 and become China's fourth largest airline.
