Seoul is served by two main airports with distinct roles. Incheon International (ICN) is the primary long-haul hub catering to international carriers and full-service airlines; it’s often viewed as pricier but offers extensive connections. Located about 48 km west of downtown Seoul, it’s reachable by AREX express or regular train (35–60 minutes), airport limousine buses (60–90 minutes) and taxis (around an hour, depending on traffic), with fares varying from budget rail fares to higher taxi rates. Gimpo (GMP) handles many domestic flights and short-haul international routes, typically used by low-cost and legacy carriers; it sits roughly 15 km from the city center and can be reached in 20–40 minutes by metro, bus, or taxi. Incheon is usually more comfortable for transfers with plentiful lounges and amenities, while Gimpo is more convenient for quick domestic hops and shorter commutes.
Ulan-Ude’s airport (UUD) functions as a regional gateway rather than a major international hub, handling mostly domestic flights and some seasonal connections to nearby countries. Carriers operating here are typically Russian regional airlines and budget operators, so fares can often be competitive compared with larger Siberian hubs. The airport lies about 12–15 km east of the city center; taxis and fixed-route minibuses (marshrutkas) are the most common options, with ride times usually around 20–35 minutes depending on traffic and fares generally modest. Pros: compact terminal and short transfer times. Cons: limited service variety and fewer timetable choices outside peak periods.
