Hangzhou Xiaoshan International Airport

Hangzhou Xiaoshan International serves the capital of Zhejiang province and the commercial heart of the Yangtze River Delta, handling 131 direct destinations across 57 airlines and ranking among mainland China's top-ten busiest airports by passenger volume. The airport's scale reflects Hangzhou's dual identity — home to Alibaba's global headquarters and a long-established tourist draw around West Lake — and its strategic position roughly 180 km southwest of Shanghai makes it a deliberate overflow valve for the saturated PVG/SHA system. HGH is a primary base for Loong Air and a major focus city for Air China, China Eastern, and Xiamen Airlines. Cargo weight is substantial: the airport is one of China's top freight gateways, driven by Zhejiang's export manufacturing base and Cainiao's smart-logistics operations. Two parallel runways — 11,811 ft (3,600 m) and 11,155 ft (3,400 m) — handle dual-stream operations, and a third runway with accompanying T4 terminal opened in 2022, lifting design capacity toward 90M annual passengers. The airport sits at 23 ft (7 m) elevation on the south bank of the Qiantang River and connects to downtown Hangzhou via Metro Line 19, an airport express route added during the 2023 Asian Games expansion. International reach skews regional — dense service to Seoul, Tokyo, Taipei, Hong Kong, and Southeast Asian capitals — with limited long-haul coverage reflecting Hangzhou's role as a secondary gateway behind Shanghai's PVG. Nonetheless HGH's combination of runway capacity, rail connectivity, and adjacent free-trade-zone logistics have positioned it as one of the fastest-growing airports in the delta region.
