Lijiang Sanyi International Airport (IATA: LJG, ICAO: ZPLJ) serves Lijiang, a UNESCO World Heritage city in Yunnan Province, southwestern China. The airport connects this popular tourist destination to major Chinese cities and supports the region's rapidly growing tourism industry. The airport is situated at a relatively high elevation, reflecting the mountainous terrain of northwestern Yunnan. It handles millions of passengers annually, driven largely by domestic leisure travelers visiting Lijiang's Old Town and surrounding natural attractions such as Jade Dragon Snow Mountain and Tiger Leaping Gorge. A significant expansion and upgrade project has been undertaken in recent years to accommodate increasing passenger demand, including improvements to terminal facilities and runway capacity.
