Seoul is served by two main airports with distinct roles. Incheon International (ICN) functions as the primary international hub, handling most long-haul and transfer traffic and hosting full-service carriers as well as many international alliances; it can be perceived as mid-to-premium in pricing for services. Gimpo (GMP) operates more as a domestic and short-haul gateway, favored by low-cost and regional airlines. Incheon sits about 45–60 km west of downtown Seoul with express trains taking roughly 45–60 minutes (fares typically in the mid-range for airport rail), while buses and taxis are common alternatives that can take 60–90 minutes depending on traffic. Gimpo is much closer (about 15 km), reachable by subway in 20–30 minutes for a low fare or by taxi in 30–50 minutes. Pros: Incheon offers modern facilities and extensive international connections; Gimpo scores for convenience and lower transfer times to the city. Cons: Incheon’s distance can add travel time and cost, while Gimpo has limited long-haul options.

Osaka is served by two main airports with different roles. Kansai International (KIX) functions as the region’s international gateway and hub for full-service carriers such as Japan Airlines and ANA, alongside several international low-cost airlines; flights can be competitively priced but international fares typically vary. Kansai sits on an artificial island about 50 km from central Osaka — the Airport Limousine bus and JR/privately operated trains take roughly 45–65 minutes to downtown (fares commonly range from budget-friendly to moderate). It offers good passenger facilities and wide international connections, though transfer times to the city can be longer. Itami (Osaka International, ITM) mainly handles domestic flights and is used by short-haul carriers and frequent business travelers; fares are often seen as convenient for quick hops within Japan. Located roughly 10 km north of central Osaka, Itami is reachable by airport bus or monorail-plus-train in about 20–30 minutes with modest fares, making it handy for same-day business trips. The airport tends to be compact and efficient for domestic travel but lacks the international route network and late-night options of Kansai.

The cost of a one-way flight from Seoul to Osaka ranges from $51 (September 2026) to $246 (January 2027). On average, the ticket price is about $97–$111.
