Buyant Ukhaa International Airport is the secondary airport serving Ulaanbaatar, Mongolia, primarily handling domestic flights and some regional services. Located southwest of the city center, it has been in operation since 1957 and continues to serve as a vital hub for connecting flights to remote provinces. The airport is equipped with basic passenger facilities, check-in counters, and transportation links to the city. Although the main international operations have shifted to Chinggis Khaan International Airport, Buyant Ukhaa remains important for domestic air travel and smaller aircraft operations.
