Bayankhongor Airport (IATA: BYN, ICAO: ZMBH) serves the city of Bayankhongor, the administrative center of Bayankhongor Province in south-central Mongolia. The airport provides essential air connectivity for a region that is otherwise accessed by long overland routes across the Mongolian steppe and Gobi Desert. The airport operates domestic scheduled services connecting Bayankhongor to Ulaanbaatar, the Mongolian capital. It is a small regional facility typical of Mongolia's network of provincial airports, which play a critical role in linking remote communities to the capital. Infrastructure at the airport is modest, reflecting the limited traffic volume of the region. It serves as a vital lifeline for local residents, government officials, and travelers heading to or from the Gobi region.
