Development

The airport was first established as Buyant-Ukhaa Central Airport^{[lower-alpha 3]} on 19 February 1957. In 1958, international flights began with flights to Irkutsk and Beijing using Ilyushin Il-14 aircraft. Regular flights from the airport started in 1961.

The terminal was upgraded to make it suitable for international traffic in 1986.

Following the Mongolian Revolution of 1990 and between 1994 and 1997 a further major upgrade of construction and air navigation was achieved with the assistance of the Asian Development Bank,^[6] making the airport compliant with ICAO standards. The US$50 million construction project was carried out by the successful bidder: a German / English joint venture of Philipp Holzmann and Wimpey Asphalt.

The airport was renamed after Chinggis Khaan (Genghis Khan) to Chinggis Khaan International Airport to celebrate the 800th anniversary of the establishment of a Mongolian State on 21 December 2005. The airport achieved steady growth during the 2000s, with passenger numbers first reaching 1 million in 2012, and reaching a peak of 1.6 million in 2019, before collapsing due to the COVID-19 pandemic.

Replacement airport

The airport was replaced by the opening of the new Ulaanbaatar International Airport in 2021.^[7] Buyant-Ukhaa is somewhat restricted, the single runway is used in one direction for arriving aircraft and in the opposite direction for departures.^[8] The new airport significantly expands capacity, and is located at the Khoshigt Valley, 52 kilometres (32 mi) south of Ulaanbaatar city center. With the new airport named Chinggis Khaan International Airport, Buyant-Ukhaa reverted to its former name on July 1, 2020.^[2]

In May 2023, it hosted the Buyant-Ukhaa Airshow, the first airshow exhibited in the country.^[9]
