Beijing Daxing International Airport — Beijing, China

Beijing Daxing International Airport, coded PKX, opened in September 2019 south of the capital as one of the most architecturally striking airports built in recent decades, its starfish-shaped terminal designed by the late Zaha Hadid's firm in partnership with French engineering group ADP Ingénierie, creating a single structure vast enough to rank among the largest airport terminal buildings anywhere in the world. The design allows passengers to reach any boarding gate from the central core within a short walk, a deliberate effort to minimize the long treks common at sprawling terminals elsewhere. PKX primarily hosts China Southern and China Eastern Airlines, both of which shifted substantial portions of their Beijing operations away from the older PEK following Daxing's opening, while also supporting high-speed rail connections that link the airport directly into China's broader transportation network. The airport sits roughly 46 kilometers from central Beijing, considerably farther out than its older sibling.
