Lanzhou Zhongchuan International Airport, a key aviation hub in Northwest China, operated over 140 passenger routes connecting more than 90 cities during the 2024 winter-spring flight season.

In March 2025, the newly completed Terminal 3 (T3) of the airport's third-phase expansion project commenced operations. All domestic and international flights (including Hong Kong, Macao and Taiwan routes) were transferred to T3, while the original T1 and T2 terminals were temporarily closed. The upgraded airport is projected to handle 38 million passengers, 300,000 metric tons of cargo, and 300,000 aircraft movements annually.
