This will be the city's second such facility and help relieve pressure on Beijing Capital International Airport, whose annual capacity has reached 100 million passengers. Foreign airlines, along with those in Hong Kong, Macau and Taiwan, can choose which airport they want to operate in, with the option of having a presence in both. Chinese carriers, except China Postal Airlines, will have to use only one airport, according to the Civil Aviation Administration of China (CAAC).
China initially planned to relocate airlines from the SkyTeam alliance to the new airport, while Star Alliance airlines would stay at the existing Beijing airport. Airlines including China Southern, China Eastern, Beijing Capital Airlines and China United Airlines will be relocated to Beijing Daxing International Airport, while carriers such as Air China, Hainan Airlines and Grand China Air will stay at Beijing Capital International Airport.
