Incheon International (ICN) serves as Seoul’s main international gateway and a major long-haul hub, handling most carriers’ premium and full-service routes as well as many transfer passengers. Located about 48 km west of downtown Seoul, it typically takes 45–70 minutes by airport express train or 60–90 minutes by airport limousine bus; fares commonly range from moderate to higher depending on service class. Pros: modern terminals, extensive lounges and transit amenities; cons: longer transfer time to the city compared with closer fields. Gimpo (GMP) functions mainly as a domestic and short-haul international airport, frequented by budget and full-service carriers on Tokyo/Shanghai/Busan routes. Only about 15 km from central Seoul, it’s usually 20–30 minutes by subway or 30–50 minutes by taxi, with low to moderate fares. Pros: quick city access and convenient ground transport; cons: fewer long-haul options and smaller terminal facilities than Incheon.

The airport lies about 6–7 km east of central Kathmandu; road transfer usually takes 20–40 minutes by taxi or ride-hail, with fares commonly falling in a low single-figure to mid-double-digit local-currency range, while airport shuttles and private transfers are also available. Pros: convenient access to the city and good onward domestic connectivity; cons: limited terminal space and occasional congestion can make peak-time waits less comfortable.
