Chinggis Khaan International Airport (ULN) is Ulaanbaatar’s primary international gateway and the country’s main hub for longer-haul and regional flights, handling most full-service carriers as well as several low-cost operators. The airport lies roughly 50–55 km southeast of the city center, with transfer times typically around 45–75 minutes by car depending on traffic. Airport buses and shared shuttles can be the most economical choice while taxis and private transfers are faster; fares are usually modest but can vary with provider and season. Pros: newer facilities and international connections; cons: substantial distance from downtown and occasional delays during winter weather. Planning extra time for transfers is advisable.

Seoul is served by two main airports with different roles. Incheon International (ICN) is the city’s primary long‑haul gateway and a major international hub, typically handling most intercontinental and full‑service carriers; flights here can be comparatively higher in price but offer broad route choices. It sits about 48 km west of central Seoul, with the airport railroad (AREX) taking roughly 45–60 minutes to Seoul Station and express trains slightly faster; bus rides are around 60–90 minutes depending on traffic, and fares usually range from moderate to premium. Pros: modern terminals, plentiful amenities and baggage options; cons: longer transfer time to downtown for some travelers. Gimpo International (GMP) functions more as a domestic and short‑haul regional airport, commonly used by budget and Korean domestic carriers as well as some nearby international flights to Japan and China. Located roughly 15 km from central Seoul, it’s often quicker and cheaper to reach — AREX and metro lines can connect you to the city in about 20–30 minutes, with airport buses and taxis offering similar or slightly faster door‑to‑door times; fares are typically lower than Incheon. Pros: convenience and shorter city access; cons: fewer long‑haul options and more limited international services.
