Chongqing Jiangbei International Airport — Chongqing, China

Few airports anywhere match the sheer scale of population that CKG serves, given that Chongqing's municipal boundaries encompass one of the largest urban agglomerations on the planet, sprawling across hilly terrain along the Yangtze and Jialing rivers. Multiple terminals and several runways handle a mix of domestic trunk routes, extensive cargo operations, and a growing menu of international connections that have positioned Chongqing as a significant inland hub within China's broader aviation network, complementing coastal giants like Shanghai and Guangzhou. Chongqing Airlines maintains a major base here, and the airport increasingly channels traffic tied to the region's automotive, electronics, and heavy industry sectors alongside its role as a logistics node for freight moving toward Europe and Central Asia. Continuous expansion projects have added terminal capacity over successive construction phases, reflecting persistent growth in both passenger and freight volumes. The airport's layout across sprawling, hilly ground required extensive engineering work, mirroring the challenging topography that defines Chongqing itself, a city famously built across steep hillsides rather than flat plains.
