Jeju International Airport is the island’s main gateway and typically functions as a busy domestic hub with a growing share of regional international flights, often serving both full-service and low-cost carriers. Flights to and from mainland South Korea are generally frequent and can be competitively priced compared with long-haul routes. The airport sits close to Jeju City—about 4–6 km from the center—making transfers quick: taxis take roughly 10–20 minutes and can be moderately priced, while local buses take 20–40 minutes for a lower fare. Car rentals and shuttle services are common for island sightseeing. Pros: very convenient for city access and short onward journeys; Cons: can be crowded during peak travel seasons and may have limited late-night services compared with larger international hubs.

Seoul is served by two main airports with distinct roles. Incheon International (ICN) is the primary international hub, handling most long-haul and full-service carriers; it’s often perceived as mid-to-upper range on fares compared with regional options. Located about 48 km west of downtown Seoul, travel to the city center typically takes 45–70 minutes by AREX express or airport limousine bus, with fares generally in a moderate range; taxis take around an hour depending on traffic. Pros: modern facilities, wide airline choice, frequent train and bus links. Cons: longer transfer times to central Seoul and occasional congestion during peak hours. Gimpo International (GMP) functions as a convenient domestic and short-haul gateway, favored by budget and regional carriers as well as some low-cost international flights to nearby countries. It lies much closer to central Seoul—roughly 15 km—so journeys by metro or bus can be as quick as 20–40 minutes, with lower fares than the long-haul airport; taxis are faster but can cost more. Pros: proximity to the city and efficient connections for regional travel. Cons: fewer long-haul options and smaller terminal facilities compared with the main international hub.

The minimum one-way ticket price from Jeju to Seoul is $19 (July 2026), while the maximum is $83 (May 2027). On average, a ticket costs $48–$52.
