Yes, you can smoke at Mongolia’s main airport. Chinggis Khaan International Airport (UBN) at Ulaanbaatar publishes an indoor smoking room in the ground-floor arrivals hall, a second indoor smoking room in the second-floor border-zone waiting hall past passport control, and a separate outdoor smoking point outside the building.
For international travel through Mongolia, Ulaanbaatar (UBN) is the airport that matters, replacing the older Buyant-Ukhaa airport closer to the city centre, which kept the IATA code ULN and remains semi-operational for limited traffic.
How Mongolian Airport Smoking Works
Mongolia’s Tobacco Control Law bans smoking in passenger stations and on public transport as enumerated public places; a separate provision requires businesses and facilities over a set size to establish at least one designated smoking area on their premises, which is the basis for the rooms and the outdoor point at Ulaanbaatar’s airport:
- An indoor smoking room in the arrivals hall, ground floor, landside
- A second indoor smoking room in the border-zone waiting hall, departures floor, past passport control
- An outdoor smoking point outside the terminal building
- E-cigarettes are not separately regulated under current Mongolian law; a proposal to bring them under the tobacco law was still under review in late 2025, and the airport publishes no separate vaping rule
Chinggis Khaan International Airport (UBN)
Mongolia’s only major international gateway, opened in July 2021 to replace the older Buyant-Ukhaa airport. Ulaanbaatar’s smoking rooms sit on both terminal floors — one in the arrivals hall and one in the departures-side border-zone waiting hall — plus the outdoor smoking point outside the building. The airport handled over 2 million passengers in 2024 through its single terminal.
Tips for Smokers at Mongolian Airports
- Ulaanbaatar keeps an indoor smoking room past passport control — you can smoke during a layover without exiting the secure zone
- Landside, the arrivals-hall room or the outdoor point outside the building both work before check-in or after landing
- E-cigarettes are not separately regulated under Mongolian law; no vaping-specific facility is published, so treat vaping as unconfirmed at the airport
- Older booking systems sometimes still show the airport’s former code, ULN — the current international airport is UBN
