Erenhot Saiwusu International Airport guide

Erenhot Saiwusu International Airport sits near the town of Saiwusu in Inner Mongolia, 27 km southeast of Erenhot and about 32 km from the Mongolian border. It opened to traffic on 1 April 2010 as a 4C-standard regional airport, built for 257 million yuan.

The airport has one concrete runway, 12/30, which is 2,800 m long. Scheduled service is mostly domestic, linking Erenhot with Hohhot, Xilinhot, Chifeng, Tongliao and Beijing Daxing. The airport handled 327,810 passengers and 5,006 aircraft movements in 2025.

Erenhot is China's largest land border crossing with Mongolia, and the airport has grown around that role. A temporary international opening was approved in 2013, and a charter service to Ulaanbaatar began that year. The airport passed national acceptance in 2024 and received its current name with approval from the civil aviation authority. It opened formally as an international air border port on 10 July 2025, when a scheduled route to Ulaanbaatar started.
