Xi'an Xianyang International Airport — Xi'an, China

Xi'an Xianyang International Airport, coded XIY, lies roughly 25 miles northwest of central Xi'an in Shaanxi province, a city famous as the eastern terminus of the ancient Silk Road and home to the Terracotta Army. Opened in 1991 to replace an older airfield closer to town, it has grown into one of northwestern China's busiest gateways, anchoring domestic networks while adding international links to Europe, Central Asia, and Southeast Asia. The airport serves as a base for Hainan Airlines and Chang'an Airlines among other carriers and has expanded terminal capacity in phases to keep pace with rising passenger numbers. Xianyang, the municipality lending the airport its name, is technically distinct from Xi'an itself, though the two form a connected metropolitan area with strong industrial and aerospace ties to the wider region.
