Yan'an Nanniwan Airport — Yan'an (Baota), China

ENY is the code for Yan'an Nanniwan Airport, which serves the city of Yan'an in China's Shaanxi province. Yan'an holds major historical significance as a base for the Chinese Communist Party during the 1930s and 1940s, and the airport supports the steady stream of domestic tourists visiting revolutionary-era historical sites in the region. ENY offers domestic flight connections to major Chinese cities, helping open up this mountainous inland area to broader travel demand. The airport replaced an older, smaller facility to accommodate growing passenger numbers and improve safety margins given the region's rugged loess-plateau terrain. Cargo and domestic passenger service remain its main functions today.
