Tianjin Binhai International Airport

Tianjin Binhai International is the principal airport for the port city of Tianjin (population 13.9M) and the secondary aviation gateway for the Beijing metropolitan region, handling roughly 17M passengers annually across 197 weekly routes to 91 destinations on 37 airlines. TSN sits 13 km (8 mi) east of downtown Tianjin and 120 km (75 mi) southeast of central Beijing, and has been strategically positioned since 2014 as a relief valve for Beijing Capital's congestion — the high-speed rail connection between the two cities allows Beijing-bound passengers to reach downtown Beijing from TSN in roughly the same total time as from Beijing Capital. The airport is the main Chinese base of Tianjin Airlines (a HNA Group carrier), a significant operating base for Okay Airways, and a major cargo hub — TSN's freight operation is one of the top ten in mainland China, serving the massive port-adjacent manufacturing cluster of the Binhai New Area. Two parallel runways (11,811 ft / 3,600 m and 10,499 ft / 3,200 m) support independent operations. Terminal 1 and Terminal 2 together handle roughly 20M annual capacity, with a major third-phase expansion including Terminal 3 (55M capacity) under construction and scheduled for opening in 2028. TSN sits at 10 ft (3 m) elevation, one of the lowest major airports in northern China, with no high-altitude performance constraints. International reach is tilted toward Northeast Asia and regional short-haul — Seoul, Tokyo, Osaka, Nagoya, Bangkok, Singapore, Kuala Lumpur, Hong Kong, and Taipei operate as regular markets. A distinctive feature is the direct Metro Line 2 connection to the terminal, which combined with the high-speed rail link to Beijing South makes TSN unusually well-integrated into the Jing-Jin-Ji megaregion's transit system despite its secondary-hub status.
