Way 1: Using Domestic routes at Incheon International Airport
The Incheon International Airport offers domestic flights to Jeju Island. However, due to the limited number of flights per day, transit through Gimpo International Airport is highly recommended to go to Jeju International Airport from Incheon International Airport (Way 2).

Way 2: Using Domestic Routes through Gimpo International Airport (Recommended)
To travel to Jeju, traveling out of Gimpo Airport is usually a better option. To go directly from Incheon Airport to Gimpo Airport for a domestic flight to Jeju, the quickest/easiest way is to take the Airport Railroad (AREX) (about half an hour). You can also take one of the buses from outside the arrival gate of Incheon Airport. For specific bus numbers, stop by the Information Center or ask outside at the bus ticket booth.
