Beijing Daxing International Airport, located on the border of Beijing and Langfang, Hebei Province, is Beijing's second international airport. 

It has been nicknamed "starfish". The terminal building is the largest single-structure airport terminal in the world, with an area of more than 1,000,000 m2 (11,000,000 sq ft).

It was completed on June 30, 2019. The opening ceremony for the airport was held on September 25, 2019, with the airport opened to the public on September 26, 2019. The first commercial flight, China United Airlines KN5302 from Ordos, landed at Beijing Daxing at 10:12 (UTC+8), September 26, 2019.

The multibillion-dollar airport, designed by the late architect Zaha Hadid and her partners, spans more than 700,00 square feet and includes four runways, a terminal the size of 97 soccer pitches, as well as customer-service robots, all of which are made to accommodate more than 72 million passengers at one time.

Nicknamed the “starfish” by local media for its resemblance to the sea creature, the airport was designed to minimise how long passengers will need to commute between gates thanks to its five concourses, which join in the centre.

According to CNN, Daxing was designed so that passengers will not need to walk any longer than eight minutes from security to the remotest gates.
