Seoul or Busan to Jeju: Flight or Ferry, and How to Book

Short answer: for most first-time visitors, flying is the easiest way to get from Seoul or Busan to Jeju. Flights from Seoul Gimpo and from Busan Gimhae take roughly an hour in the air, depart all day, and are often cheap if you book a little ahead. A ferry is worth it only if you enjoy slow travel, want to bring a car, or are already on Korea's south coast near Mokpo, Wando, Goheung or Yeosu. From Busan, do not count on a direct ferry: the overnight service has been suspended at times, so check the operator before you plan around it.

This guide compares the two options, explains how to book each one as a foreign visitor, and covers the small details that trip people up on the day.

Flight vs ferry at a glance

Flight: about 1 hour in the air from Gimpo (Seoul) or Gimhae (Busan). Many airlines, departures from early morning to late evening, and you land at Jeju International Airport, close to Jeju City.
Ferry: from about 2.5 hours (Wando) to 4–5 hours (Mokpo), plus the time it takes to reach the port from Seoul or Busan. Overnight boats run on some longer routes. Good for cars, bikes, scenery and travelers who do not want to fly.

If your time is short, the flight wins easily. Getting from Seoul to a southern ferry port alone takes several hours by KTX or bus, so a "cheap" ferry can cost you most of a day.

Flying to Jeju

From Seoul: use Gimpo, not Incheon

Almost all domestic flights from Seoul to Jeju leave from Gimpo International Airport, not Incheon. Gimpo is on Seoul subway lines 5 and 9, AREX and the Gimpo Goldline, so it is easy to reach from most of the city. Seoul Gimpo–Jeju is one of the busiest air routes in the world, which means many daily departures and plenty of competition on price.

If you are landing at Incheon from abroad and want to connect straight to Jeju, look for a through-ticket on Korean Air or Asiana, or allow plenty of time to transfer to Gimpo. Our guide to Gimpo Airport transport explains how to get there and back.

From Busan: fly from Gimhae

Flights from Busan leave from Gimhae International Airport, which is linked to the city by the Busan–Gimhae Light Rail and airport buses. The flight is short, and departures run throughout the day.

Which airlines fly the route

Full-service carriers (Korean Air, Asiana) and several low-cost carriers such as Jeju Air, Jin Air, T'way and Air Busan fly these routes. Low-cost tickets often include a smaller free baggage allowance, so check what is included before comparing prices. Fares go up sharply on weekends, during school holidays and around Chuseok and Seollal.

How to book as a foreigner

Book on the airline's English website or app, or through a flight comparison site. Most foreign cards work, but if a Korean site fails at payment, try the airline's global site.
Enter your name exactly as it appears in your passport.
Bring your passport to the airport. Domestic flights still require ID, and for visitors that means a passport.
Aim to arrive at the airport about an hour before departure, earlier on busy holiday weekends. Check your airline for the exact check-in cut-off time.

Taking the ferry to Jeju

Main routes from the mainland

Wando – Jeju: the shortest common crossing, around 2.5–3 hours. Wando is on the far south coast, so it suits road trips more than travel by public transport.
Mokpo – Jeju: a popular route of about 4–5 hours, often on large car ferries. Mokpo can be reached from Seoul by KTX, which makes it the most practical ferry option from the capital without a car.
Goheung (Nokdong) and Yeosu – Jeju: other south-coast routes, useful if you are already exploring Jeollanam-do.
Incheon – Jeju: a long overnight route that has run in recent years. Check that it is operating on your dates.
Busan – Jeju: the overnight ferry from Busan has been suspended at times, and current information online is inconsistent. Treat it as "maybe" and confirm with the operator before you plan around it.

How to book a ferry

Korea's official coastal ferry booking system is run with the Korea Shipping Association, and some routes can also be booked on the operators' own websites. Several international travel platforms have started selling Jeju ferry tickets in English too, which is the easiest choice if Korean-only booking pages give you trouble. A few tips:

Have your passport ready. You need ID to board a Korean ferry, and your name and passport number may be checked against the passenger list.
Book early for weekends, summer and holidays, especially if you bring a car, because vehicle space sells out first.
Arrive at the terminal well before departure. Many operators ask passengers to check in about an hour early, but confirm on your ticket.
Sailings can be cancelled in strong winds or high waves. If the weather looks rough, check the operator's notice the day before and keep your plans flexible.

What the ferry is like

Large Jeju ferries usually offer several classes, from open floor-style rooms where passengers sit or lie on mats to private cabins. There is often a convenience store or snack bar on board. If you are prone to seasickness, choose a larger boat, sit near the middle of the ship and bring medicine from a Korean pharmacy before you go.

Bringing a car or renting one on Jeju

If you are on a Korean road trip in your own car, a car ferry from Mokpo or Wando can save the cost of renting on the island. For most visitors, though, it is simpler to fly and either rent a car on Jeju or use the island's bus network. Renting requires an International Driving Permit that is valid in Korea. If you do not drive, our guide to getting around Jeju without a car shows how far the buses can take you.

Which option should you choose?

Short trip from Seoul or Busan: fly. It saves the most time.
Exploring the south coast (Mokpo, Wando, Yeosu): take the ferry from the nearest port. It fits naturally into the route.
Driving your own car: take a car ferry, and book vehicle space early.
Afraid of flying or curious about the sea route: the ferry is a calm, scenic alternative when the weather is good.

LUMI from POPORO CITY puts it simply: "Fly there for the time, and take the ferry when the trip itself is the fun part."

Quick tips

Seoul flights to Jeju leave from Gimpo, not Incheon.
Carry your passport for both flights and ferries.
Book weekends and Korean holidays early, because prices rise and seats sell out.
Check ferry weather notices the day before departure.
Confirm current fares, schedules and baggage rules on the airline or ferry operator's official site.

FAQ

How long is the flight from Seoul to Jeju?

About an hour in the air from Gimpo Airport. Add time to get to Gimpo, check in and go through security.

Is there a ferry from Busan to Jeju?

There has been an overnight ferry, but it has been suspended at times and online information conflicts. Check with the operator for your dates before planning around it, or use the Mokpo or Wando routes.

Can foreigners book Korean ferries online?

Yes. Some routes can be booked on the official coastal ferry system or the operators' websites, and some Jeju routes are now sold on English-language travel platforms. You will need your passport details.

Do ferries get cancelled?

Yes, sailings can be cancelled in bad weather, especially in winter and during typhoon season. Keep a backup plan and check the operator's notices.
