Altay Xuedu Airport — Altay, China

Altay Xuedu Airport, serving the city of Altay in China's far northwestern Xinjiang Autonomous Region, runs its single runway at 2,460 feet above sea level. This airport supports a part of China that borders Kazakhstan, Russia, and Mongolia, making air travel considerably more practical than the long overland distances involved. Xinjiang is China's largest province-level region by area, and settlements like Altay sit far from the country's eastern population centers. Domestic connections dominate here, linking this remote northern corner of Xinjiang to Urumqi and other regional hubs rather than serving international arrivals directly.
