Diqing Shangri-La Airport — Diqing (Shangri-La), China

DIG is the code for Diqing Shangri-La Airport, serving the mountainous Diqing Tibetan Autonomous Prefecture in northwestern Yunnan, China. Sitting at high elevation near the town branded as Shangri-La (formerly Zhongdian), the airport primarily handles domestic flights connecting this remote plateau region to major Chinese hubs like Kunming, Chengdu, and Guangzhou. Its high-altitude runway design accounts for thinner air, which affects aircraft performance and payload calculations. The airport supports tourism to the area's Tibetan monasteries, alpine scenery, and gorges, as well as local trade and passenger travel that would otherwise require long overland journeys through difficult terrain. DIG is essential infrastructure for a prefecture where road travel is slow and seasonal weather can be severe.
