Getting to Jeju Island is one of the more straightforward logistics decisions in Korean travel: in almost every case, you fly there. The Seoul–Jeju air route carries more passengers per year than any other domestic route in the world, which means dozens of daily departures, multiple carriers competing on price, and a 1-hour flight that is shorter than many Seoul subway journeys. What takes most first-time visitors by surprise is which Seoul airport to use — and that question alone is worth getting right before you book anything.
Flying from Seoul: Gimpo, Not Incheon
If you are already in Seoul and want to fly to Jeju, use Gimpo International Airport (GMP). Gimpo handles all domestic flights and sits inside the city boundaries — reachable from central Seoul in 30–40 minutes via the Seoul Airport Railroad or Line 5 subway. The Gimpo–Jeju flight takes approximately 1 hour 10 minutes.
Do not make the mistake of navigating to Incheon International Airport (ICN) for a domestic Jeju flight — Incheon is 60+ kilometres west of Seoul, handles international traffic, and will cost you an extra 90 minutes of transit time each way for no reason. Incheon does run Jeju flights (primarily for passengers transiting internationally), but for Seoul-based departures, Gimpo is the clear choice.
How to get to Gimpo Airport from Seoul:
- Seoul Airport Railroad (AREX): From Seoul Station or Hongik University Station — approximately 20–25 minutes to Gimpo Airport Station. Fare around ₩2,000–2,500 as of 2026.
- Subway Line 5: From Yeongdeungpo or Yeouido area — approximately 30 minutes. Integrated into the standard T-money subway fare.
- Taxi: From central Seoul (Myeongdong, Hongdae), expect 30–50 minutes depending on traffic; ₩25,000–40,000 by meter, though this varies significantly.
Airlines and What to Expect to Pay
Six major carriers operate the Seoul–Jeju route regularly as of 2026: Korean Air, Asiana Airlines, Jeju Air, Jin Air, T’way Air, and Air Busan. Competition keeps fares relatively accessible, but prices fluctuate significantly by season and how far ahead you book.
Budget carriers (Jeju Air, Jin Air, T’way): ₩40,000–80,000 one way when booked 2–3 weeks ahead. Prices compress closer to ₩30,000–40,000 during promotional periods and can spike above ₩150,000 at peak times (summer holidays, Chuseok, major spring weekends).
Full-service carriers (Korean Air, Asiana): ₩70,000–130,000 one way on average. Meals included on most services; more generous baggage allowances. Worth the premium if you are carrying luggage over the budget carrier limits.
Check prices directly on airline websites and comparison tools (Naver Flight, Kayak, Google Flights) before buying. Verify current pricing when you book — fares on this route shift substantially with demand. Book at least 1–2 weeks ahead for summer and spring travel.
Flying from Busan to Jeju
Gimhae International Airport (PUS) in Busan also operates direct Jeju flights. The flight takes approximately 50 minutes — slightly shorter than from Seoul. This matters if your Korea itinerary has you spending time in Busan: you can fly Busan–Jeju directly without backtracking to Seoul, then fly Jeju–Seoul (Gimpo) at the end to exit the country via Incheon. That routing saves a full Seoul–Busan transit leg on your trip. For context on the Busan side of things, the day trips from Busan guide covers the southern mainland before you cross to the island.
Carriers: Korean Air, Asiana, Jeju Air, Air Busan all operate the Busan–Jeju route. Fares and booking approach are similar to the Seoul route; check current availability and pricing when planning.
Flying from Incheon if Arriving Internationally
If you are arriving in Korea for the first time and landing at Incheon International Airport, you have the option to connect directly to Jeju without going into Seoul first. This makes sense if Jeju is your first Korean destination — rather than checking into Seoul, travelling to Gimpo, and then flying to Jeju the next day, you can connect at Incheon in the same day.
Korean Air and Asiana both operate Incheon–Jeju connections. The flight is approximately 1 hour 20 minutes. Minimum connection time from an international arrival at Incheon is typically 2–3 hours (customs, baggage, domestic terminal transit). Incheon’s domestic terminal (Terminal 1, domestic departure zone) is connected to the international terminal by a shuttle bus — allow extra time for this transfer. Check your airline’s recommended connection time when booking. Budget carriers do not typically connect international to domestic at Incheon.
Ferry Option: Slow and Situational
Ferries sail to Jeju from several mainland ports, primarily Mokpo (South Jeolla Province) and Wando. Both are on the southern Korean coast — Mokpo is reachable from Seoul by KTX high-speed train in about 2 hours 30 minutes; Wando requires a longer bus connection.
The ferry crossing itself takes 10–13 hours depending on vessel type and port. Overnight ferries run on some routes. Fares for foot passengers run approximately ₩40,000–80,000 one way — roughly equivalent to a budget airline fare for a trip that takes ten times as long. The practical reason to take the ferry is if you are bringing a vehicle (car or motorbike) to Jeju; foot passengers are almost always better served by flying.
Weather-related cancellations are common during typhoon season (July–September) and in rough winter conditions. If you are planning around a ferry, build flexibility into your schedule accordingly.
Getting Around Once You Land
Jeju International Airport (CJU) is compact and efficient. Arrivals exit into a main hall with car rental counters immediately visible. Collect your luggage, locate your rental company’s counter (or take the shuttle to the off-airport rental lot — usually a 5-minute bus ride), and complete your paperwork. You will need:
- Your home country driving licence (original)
- Your International Driving Permit (IDP) — obtain this before departure from your national automobile association
- Passport and credit card for the rental deposit
Car rental prices at the airport run approximately ₩40,000–60,000 per day for a standard vehicle as of 2026 — see the Jeju by rental car guide for booking advice, particularly for spring and summer travel. For visitors who prefer not to drive, the Airport Limousine Bus (노선 600, 800 series) connects the airport to Jeju City hotels in 20–30 minutes for around ₩1,700–2,500 and runs to Seogwipo in about 1 hour. Taxis are metered and available immediately outside the arrivals exit. For full context on navigating the island, the complete Jeju Island travel guide covers transportation and logistics in detail.
How long is the flight from Seoul to Jeju?
The flight from Gimpo Airport (GMP) in Seoul to Jeju International Airport (CJU) takes approximately 1 hour 10 minutes. From Incheon Airport (ICN), allow about 1 hour 20 minutes. The Seoul–Jeju route is one of the world’s busiest domestic air routes, with multiple daily departures from both airports across six carriers.
What is the cheapest way to get to Jeju Island from Seoul?
Budget carriers (Jeju Air, Jin Air, T’way Air) offer the lowest fares on the Gimpo–Jeju route, with prices from roughly ₩40,000–80,000 one way when booked 2–3 weeks ahead as of 2026. Promotions occasionally drop fares lower. The ferry from Mokpo is similarly priced for foot passengers but takes 10–13 hours — the budget airline is almost always the better value when total time is factored in.
Do you need an International Driving Permit for Jeju?
Yes — an International Driving Permit (IDP) is required to rent and drive a car in Jeju (and throughout South Korea). You must obtain the IDP from your national automobile association before you travel, as it cannot be obtained in Korea. The IDP is used alongside your original home country driving licence, not as a replacement. Without both documents, rental companies will not complete the paperwork.
Can you take the KTX train to Jeju Island?
No — KTX high-speed rail does not connect to Jeju Island, as the island is separated from the mainland by 80 kilometres of sea. There is a long-discussed plan for a fixed link (tunnel or bridge) connecting Jeju to the mainland, but no such link exists as of 2026. The options are flight or ferry; for most visitors, the 1-hour flight from Gimpo is the definitive answer.
