Seoul is served by two main airports with distinct roles. Incheon International (ICN) is the city’s primary international hub, handling most long-haul and full-service carriers and often seen as a premium gateway; it sits about 48 km west of downtown and is reachable by AREX express trains (about 45–60 minutes) or airport buses (60–90 minutes), with fares typically in the mid-range for public transit. Gimpo Airport (GMP) functions more as a domestic and short-haul regional airport, catering to low-cost and legacy carriers on routes to Japan, China and domestic cities; it’s much closer to the center (around 15 km), with subway or taxi rides commonly taking 20–40 minutes. Pros: ICN offers extensive international connections and modern facilities, while GMP is convenient for quick domestic transfers. Cons: ICN’s longer distance can add travel time and cost, whereas GMP has fewer long-haul options and can be busy during peak hours.

Osaka is served mainly by Kansai International (KIX) and Itami/Osaka International (ITM). Kansai is the international gateway and a full-service hub for long-haul and many regional carriers, while Itami functions as a busy domestic airport favored by legacy Japanese airlines and some full-service regional routes. KIX sits on an artificial island about 50–60 minutes from central Osaka by train or express bus; fares typically range from mid-tier to higher depending on service. Itami is closer—roughly 20–30 minutes by shuttle or airport limousine bus—and often feels more convenient for quick domestic connections. Transport options include frequent trains, airport limousines and taxis; trains and buses are usually the fastest and most economical. Pros: KIX offers broad international connectivity and modern facilities; Itami delivers speed for domestic travel. Cons: KIX can be farther and may incur extra transit time, while Itami handles fewer international options.
