Jeju International Airport is a road-and-bus hub, not a rail station. Decide your first destination before leaving the terminal: Jeju City, Jungmun Tourism Complex and central Seogwipo use different corridors.
Korea Airports Corporation currently directs ordinary city and intercity bus users to the bus area outside Gate 2, taxi users across the road from Gate 3, and airport-limousine users to the area by Gate 5. For Jungmun and Seogwipo, Jeju's official bus system lists Airport Limousine 600 from the airport through Jungmun hotels, the convention center and World Cup Stadium toward Seogwipo, while route 800 links the airport with Seogwipo without following the same Jungmun hotel corridor. Route 800-1 is an early/late-day variant, so do not assume every 800-series trip runs all day.
The official Jeju bus system currently lists adult limousine fares by distance, with route 600 at KRW 1,300–5,500 and route 800/800-1 at KRW 1,300–5,000. Other express and local routes also serve the airport, and their usefulness depends on your exact stop.
A time-sensitive point matters now: Jeju's bus information system says schedule reductions and timetable adjustments take effect on October 5, 2026, affecting several express routes and the 600 and 800 airport limousines. Check the live route and timetable on the travel day rather than copying an older departure time.
If you choose a taxi, the airport's official estimate page currently gives examples such as about 30 minutes to Jeju City Hall and about 80 minutes to Jungmun Tourism Complex, but traffic and the exact destination can change both time and fare.
