Seoul is served primarily by two airports with distinct roles. Incheon International (ICN) is the region’s main international gateway and a long-haul hub for full-service carriers; it typically handles most intercontinental flights and can be pricier to reach but often competitive for transpacific routes. The airport lies about 48 km west of central Seoul, with express train options (Incheon Airport Railroad Express) taking roughly 45–60 minutes and airport buses around 50–70 minutes; fares typically range from moderate to higher depending on service. Gimpo Airport (GMP) acts more as a domestic and short-haul regional node, frequented by low-cost and legacy carriers for flights to destinations across Korea, Japan, and China. Located roughly 15–20 km from downtown, Gimpo is reachable by subway in about 20–30 minutes or by taxi in similar time with lower fares. Incheon offers extensive amenities and international transfer convenience but can mean longer surface travel; Gimpo is often more convenient for quick domestic hops though with fewer long-haul services.
Ulaanbaatar is served primarily by Chinggis Khaan International Airport (ULN), a modern international hub located about 45–50 km south of the city center that typically handles most long-haul and regional flights. The airport often hosts full-service carriers as well as regional and low-cost operators, so fares can range from budget-friendly to premium depending on carrier and season. Ground transport options include airport shuttle buses (roughly 1–1.5 hours), private taxis or ride-hailing (approximately 50–70 minutes depending on traffic) and pre-arranged hotel transfers; fares can vary from modest shuttle fees to higher taxi rates. Pros: relatively new facilities and international connectivity; cons: significant distance to downtown and occasional traffic delays.
