Domestic flights and getting to Jeju

The most common way is a domestic flight from Gimpo Airport to Jeju, which usually takes about an hour and 15 minutes. There are also Jeju flights from Incheon and other regional airports. Ferries are another option, but from Seoul they take far longer overall.

Yes. Foreign visitors must show their passport for identity checks even on domestic flights. Long-term residents can use their residence card instead. If you leave your passport at the hotel, you may not be allowed to board, so always bring it.

Both full-service carriers and several low-cost carriers operate domestic flights. Low-cost airlines may charge separately for checked bags or seat selection, but this depends on the airline and fare type. As of November 2026, a merger between major carriers is still being completed, so check which airline actually operates your flight when booking.

For domestic flights, arriving about an hour before departure is usually enough, but go earlier on weekends and in peak season when security lines are long. Check-in and baggage drop close well before departure, so check your airline's deadlines. Using a mobile boarding pass can save time.

Yes. As of November 2026, passenger ferries sail to Jeju from ports such as Mokpo and Wando. Regular routes from some other ports have ended or are not running, so check the ferry operator's notices. Some ferries carry vehicles, and weather can cause cancellations, so confirm the sailing before you set off.

Power banks cannot go in checked baggage and must be carried on board, with limits on capacity and quantity. Airlines have recently tightened rules on how power banks are used or stored in the cabin. Check your airline's latest rules before you fly.

Unlike international flights, domestic flights in Korea do not apply the 100 ml container and clear zip bag limit to liquids in carry-on bags. You still go through security screening, and dangerous goods and certain items remain restricted on domestic flights. These rules are as of November 2026, so check airport and airline guidance before you fly.

Even with many flights, Jeju routes sell out quickly and prices rise on weekends, holidays and during the summer vacation season. Book early once your dates are fixed, and weekday early morning or late evening flights tend to have more availability. Compare several airlines' websites before buying.

Yes. Strong winds, typhoons and heavy snow can delay or cancel flights to and from Jeju. If a flight is cancelled, the airline notifies you by text or app and offers alternatives or a refund. If you are connecting to an international flight home, leaving a day of buffer is safer.

The free checked baggage allowance depends on the airline and fare type. Full-service carriers often include a set weight, while some low-cost fares include no checked bags at all. Check the baggage terms when booking and add bags in advance if needed, which is usually cheaper than paying at the airport.

Yes. There are routes from Gimpo to cities such as Busan, Gwangju, Yeosu and Ulsan, and from Jeju to many regional cities. Routes and schedules change by season, and where the KTX is fast there are few or no flights. Once you know your destinations, compare trains and flights side by side.

On weekday afternoons it is usually quick, but lines can be long on weekend mornings, holidays and in the vacation season. Gimpo also offers services that let pre-registered travelers pass through faster. If you expect crowds, arrive earlier than usual.

Public transport on Jeju is not as dense as in Seoul, so many visitors rent a car. If you do not drive, combine express buses from the airport, local buses, taxis and organized tours. Distances can be long, so choose your accommodation location carefully.

Contact the airline counter or customer service right away. Depending on your fare rules, you may be able to switch to a later flight for a fee or get a partial refund, but cheap fares may not allow changes. It helps to read the fare conditions before you fly.

Check in online through the airline's app or website to receive a mobile boarding pass, or get one at an airport kiosk or counter. Foreign travelers may need to scan their passport at the kiosk. If you have checked baggage, you still need to visit the bag drop counter.

Jeju International Airport can be very crowded at peak departure times, so security and check-in may take a while. If you are returning a rental car, include the return process and shuttle ride in your timing. Tangerines bought as souvenirs are generally fine in the amounts a traveler carries, but check the rules if you plan to take very large quantities.

Children who occupy a seat need their own ticket, though a child discount may apply. On domestic flights, infants under two who sit on a parent's lap without their own seat usually fly free. Child fares and discount rates vary by airline and fare type, so check when booking.

If you belong to an airline's frequent flyer program, you can earn miles on domestic flights or redeem them for award tickets. Whether partner airline miles apply depends on the program. Low-cost carriers sometimes run their own points systems instead.

Islands such as Ulleungdo and those off the south and west coasts are mostly reached by passenger ferry. Island ferries can be cancelled in bad weather, so leave some flexibility in your schedule, especially for Ulleungdo, which involves an open-sea crossing. Check sailing information from the ferry operator and official maritime services before you set off.

Airline apps and websites show schedules, delays and cancellations. For airports such as Gimpo, Gimhae and Jeju, the Korea Airports Corporation's official site provides congestion and transport information. On bad weather days, keep checking notifications right up until departure. Turning on airline app alerts helps.
