Yuncheng Yanhu International Airport — Yuncheng (Yanhu), China

Yuncheng Yanhu International Airport, assigned the code YCU, serves Yuncheng, a prefecture-level city in the southwestern corner of Shanxi province known for one of China's oldest salt-producing sites. The airport takes its name from nearby Yanhu, the ancient salt lake whose mineral-rich, sometimes pink-tinted waters have been harvested for salt since antiquity and are often compared to the Dead Sea. Originally a smaller domestic facility, the airport was expanded and rebranded with international status as regional air travel demand grew, though its schedule still leans heavily toward domestic Chinese routes. Yuncheng's broader region is also tied to the legendary general Guan Yu, celebrated across Chinese culture, giving the area strong cultural tourism appeal alongside its salt-lake scenery. The airport functions primarily as a regional connector, linking Yuncheng to major hub cities rather than serving as an international hub itself.
