Seoul is served primarily by two airports with different roles: Incheon International (ICN) functions as the city’s major international hub, handling most long-haul and premium carriers, while Gimpo (GMP) typically serves domestic routes and short-haul flights to nearby Asian cities, often favored by budget and regional operators. Incheon sits about 48–60 km west of central Seoul; travel time by AREX express or airport limousine bus is usually 45–70 minutes depending on traffic, with fares generally in the mid-range for airport transfers. Gimpo lies much closer, around 15–20 km from downtown, with subway and bus links typically taking 20–40 minutes and offering lower fares. Pros: Incheon provides extensive international amenities, lounges and frequent intercontinental connections; Gimpo is more convenient for quick domestic hops and often quicker to reach from central neighborhoods. Cons: Incheon’s distance can add transfer time and cost, whereas Gimpo has fewer long-haul options and more limited international services.

Irkutsk International Airport (IKT) serves as the primary air gateway for eastern Siberia and usually functions as a regional international hub rather than a large global transfer point. It typically handles a mix of domestic flights to Moscow and other Russian cities along with seasonal international services; airlines are often national carriers and a few low-cost or regional operators. The airport sits roughly 50–60 km southeast of Irkutsk city center; travel by car or taxi can take about 50–70 minutes depending on traffic, with fares usually moderate for local standards. There are also shared shuttles and occasional bus connections taking around 70–90 minutes for a lower cost. Pros include direct links to major Russian destinations and a relatively compact terminal for straightforward transfers; cons can be limited late-night services, variable seasonal schedules, and a longer distance from downtown than some regional airports.

In different months, ticket prices from Seoul to Irkutsk vary: minimum — $320 (September 2026), maximum — $400 (May 2027). Typically, the flight costs $359–$727.
