Buyant-Ukhaa International Airport

Buyant-Ukhaa International Airport (ZMUB) is a medium airport in Ulaanbaatar, Mongolia. Pilots and dispatchers reference it by ICAO code ZMUB or IATA code ULN. It sits in Asia.

Buyant-Ukhaa International Airport is a regional airport primarily serving general aviation, charter, and corporate flight departments.

Buyant-Ukhaa International Airport sits at 4,364 ft above sea level. Hot-and-high conditions can meaningfully reduce takeoff performance in summer — planners should factor density altitude into payload and fuel decisions.

Local operations run on Asia/Ulaanbaatar. Without scheduled airline traffic, the field tends to be quieter and more flexible for charter and corporate operations — a useful characteristic for early morning, late night, or short-notice flights that would be impractical at a hub.

SkyAccess inventory for ZMUB updates continuously as operators publish new empty legs and one-way repositioning trips. Pricing on each leg is available with a free account, and an inventory alert will email you the moment a leg appears on the route you care about.

Use this page to compare ZMUB against nearby alternatives, browse live empty-leg pricing in both directions, and brief yourself on the runway and elevation profile before you book.

Buyant-Ukhaa International Airport, formerly called Chinggis Khaan International Airport from 2005 to 2020, is a semi-operational international airport serving Ulaanbaatar, Mongolia, situated 18 km (11 mi) southwest of the capital. Largely replaced by a new airport, it currently functions as a backup airport for the former, with a view to being used for flight training as well as for special, charter, and government flights.
