Jiayuguan International Airport (IATA: JGN, ICAO: ZLJQ) serves Jiayuguan, a city in Gansu Province, northwestern China. The airport acts as the primary air gateway for the region, connecting it to major Chinese cities and supporting both tourism and industrial activity tied to the nearby Jiayuguan Pass, the western terminus of the Ming Dynasty Great Wall. The airport underwent upgrades and was elevated to international status to handle growing passenger demand and to support regional economic development in the Hexi Corridor. It serves as an important hub for travelers visiting the Silk Road heritage sites of the area. Flights primarily connect Jiayuguan to hubs such as Beijing, Shanghai, Chengdu, and Xi'an, with Chinese domestic carriers operating the majority of routes.
