Ulaanbaatar Chinggis Khaan International Airport

Ulaanbaatar Chinggis Khaan International Airport (ZMCK) is a large airport in Ulaanbaatar (Sergelen), Mongolia. Pilots and dispatchers reference it by ICAO code ZMCK or IATA code UBN. It sits in Asia.

Ulaanbaatar Chinggis Khaan International Airport is a commercial-airline hub that also handles a steady stream of private and corporate traffic. Mixed commercial and private operations mean planners should expect slot coordination, handling agent involvement, and the usual international hub procedures.

Ulaanbaatar Chinggis Khaan International Airport sits at 4,482 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. Because the field hosts scheduled airline operations, private operators should expect a defined slot environment, possible CDM coordination at peak banks, and limited ramp availability during major event weekends. Booking FBO ramp space in advance is normal practice.

SkyAccess inventory for ZMCK 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.

As one of the larger fields in Mongolia, ZMCK tends to be the natural choice for long-range international charters and crew-rest-required flights.

Chinggis Khaan International Airport, also referred to as New Ulaanbaatar International Airport, is the primary airport serving Ulaanbaatar, and is Mongolia's main international airport. It opened on 4 July 2021, replacing Buyant-Ukhaa International Airport.
