Seoul is served mainly by two airports with distinct roles. Incheon International (ICN) is the city’s principal international hub, handling most long-haul and premium carriers and often perceived as pricier for transfers and amenities; it sits roughly 48 km west of downtown and is linked by the AREX express and all-stop trains (about 43–60 minutes, fares typically mid-range), airport buses (60–90 minutes, fares vary), and taxis (60+ minutes, higher fares). Gimpo (GMP) functions as a domestic and short-haul international gateway favored by budget and regional airlines; it’s much closer at about 15 km, reachable by AREX or subway in 20–30 minutes for modest fares, buses and short taxi rides. Pros: Incheon offers extensive facilities and global connectivity; Gimpo is convenient for quick city access. Cons: Incheon’s distance can add travel time and cost, while Gimpo has fewer long-haul options and potentially smaller lounge services.

Suvarnabhumi Airport (BKK) is Bangkok’s main international gateway and a major Southeast Asian hub, typically handling most long-haul and full-service carriers while also serving some low-cost airlines. It sits about 30–35 km east of central Bangkok; road transfer by taxi or airport limo usually takes 30–60 minutes depending on traffic, with fares commonly in a moderate range relative to local standards. The Airport Rail Link connects to the city center in roughly 25–35 minutes at affordable fares, and buses and ride-hailing are widely available. Pros: modern facilities, ample international connections and frequent services; cons: can be crowded and subject to heavy road traffic for surface transfers. Don Mueang International Airport (DMK) functions as Bangkok’s budget and domestic-focused airport, typically hosting many low-cost carriers and regional flights. It’s located about 20–25 km north of central Bangkok; taxi or ride-share trips usually take 30–50 minutes depending on congestion, with fares generally lower than longer-distance transfers. There are public buses and shuttle services linking to the city and to Suvarnabhumi, and transfer times can vary. Pros: often cheaper fares and quicker turnaround for domestic trips; cons: fewer long-haul options and more basic passenger amenities compared with the main international hub.
