Chongqing - Beijing Daxing International Airport is one of two international airports serving Beijing. It is located on the border of Beijing and Langfang, Hebei Province.

The terminal building was designed by British architects Zaha Hadid Architects, French planners ADPI, and partners and executed by the Beijing Institute of Architectural Design (BIAD).

After almost five years of construction, the USD 11.4 billion facility features a 700,000 ㎡ terminal, the world's largest single-building airport terminal, and sits on 47 k㎡ of land. 

The airport opened on September 25, 2019—just six days before the 70th anniversary of the founding of the People's Republic of China.

Now, it is a hub for SkyTeam alliance airlines and some Oneworld members, while Hainan Airlines and most Star Alliance members have remained at Beijing Capital International Airport.

Upon the opening of the Daxing Airport, Beijing Nanyuan Airport, the oldest airport in China, closed the same day.
