Bangkok is served primarily by two airports with distinct roles. Suvarnabhumi (BKK) is the city’s international hub, handling most long-haul and full-service carriers and typically offering a wider range of lounges, shops and airport hotels; it sits about 30–40 km east of downtown Bangkok, with the Airport Rail Link taking roughly 25–35 minutes to the city center and taxis or ride-hailing usually 30–60 minutes depending on traffic (fares can vary widely). Don Mueang (DMK) is a budget- and regional-focused airport north of the city, commonly used by low-cost carriers and domestic flights and about 20–25 km from central Bangkok; travel times by taxi are often 30–50 minutes while buses and shuttle services can take longer but are cheaper. BKK can be more comfortable for international transfers and amenities, whereas DMK can be more economical and quicker for short domestic hops—note that connections between the two airports require extra time and planning.

Seoul is served primarily by two airports with distinct roles. Incheon International (ICN) is the city’s major international hub, handling most long-haul carriers and premium services; it’s located about 48 km west of central Seoul and typically takes 45–70 minutes by Airport Railroad (AREX) or 60–90 minutes by highway, with fares generally in the mid-range for public rail and higher for express services and taxis. Gimpo (GMP) functions as a domestic and short-haul international gateway favored by low-cost and regional carriers, sitting roughly 15 km from downtown and reachable in 20–40 minutes by subway or 25–50 minutes by road. Pros: Incheon offers extensive amenities, transit links and duty-free shopping, while Gimpo can be quicker for domestic connections and cheaper fares; cons: Incheon’s distance can add travel time and cost, whereas Gimpo has fewer long-haul options and limited premium services.
