Tribhuvan International Airport (KTM) in Kathmandu is Nepal’s primary international gateway and typically functions as the country’s main hub for both international and domestic flights. It usually hosts full-service carriers and regional airlines, with budget operators also offering connections to nearby cities. The airport sits about 6–8 km from Kathmandu’s city center; road transfers typically take 20–45 minutes depending on traffic, with taxis and airport shuttles being common (fares often range from modest local rates to higher tourist fares). Pros: relatively close to downtown and convenient for onward domestic connections. Cons: can be crowded and experience delays, with limited modern facilities compared with larger international hubs.
Seoul is served by two main airports with distinct roles. Incheon International (ICN) is the primary international hub for long-haul flights and many full-service carriers; it’s typically seen as a premium gateway with extensive lounges, transfer facilities and a wide range of international connections. Located about 48 km west of downtown Seoul, travel to the city center can take roughly 45–70 minutes by Airport Railroad Express (AREX) or 60–90 minutes by highway depending on traffic; fares for AREX and buses generally fall into a mid-range band for the region. Gimpo Airport (GMP), closer at around 15 km west of central Seoul, mainly handles domestic flights and select short-haul international routes, attracting low-cost and domestic carriers and often offering cheaper fares for short hops. Ground links from Gimpo include the AREX commuter train and subway lines that usually deliver trip times of 20–40 minutes to central districts at modest fares. Pros: Incheon offers extensive amenities and international connectivity; Gimpo is convenient for quick domestic transfers and shorter city access. Cons: Incheon’s distance can mean longer transfers and occasional traffic delays; Gimpo can be busier and more limited for long-haul services.
