Bangkok is served mainly by two airports with different roles. Suvarnabhumi (BKK) is the international hub handling most long-haul and full-service carriers; it’s usually seen as the city’s primary premium gateway and is about 30–35 km east of downtown (roughly 30–60 minutes by car depending on traffic). Transfer options include the Airport Rail Link to central stations (about 25–35 minutes, moderate fares), taxis and ride-hailing (variable time and cost). Don Mueang (DMK) functions as the budget and domestic base, favored by low-cost carriers and some regional flights; it sits about 20–25 km north of the centre (30–50 minutes by road) and is reachable by buses, local trains and taxis. Pros: BKK tends to offer more transit amenities and airline choices, while DMK can be cheaper and quicker for domestic/low-cost travel; cons: both can be affected by heavy road traffic and transfers may take longer during peak hours.

Ulaanbaatar’s main gateway is Chinggis Khaan International Airport (ULN), a modern international hub handling most long-haul and regional flights and serving national carrier MIAT alongside international airlines. The airport is located about 20–25 km south of the city center; road transfers typically take 30–60 minutes depending on traffic and weather, with taxis, airport shuttles and private transfers as common options (fares can vary from budget-friendly shared shuttles to higher taxi or private transfer rates). Facilities are relatively new and straightforward, though winter conditions can affect comfort and punctuality. Pros: international connectivity and recent amenities; cons: distance from downtown and possible seasonal delays.
