Cheap Flights from Jeju to Seoul

Book well ahead for December, when fares tend to be lowest on this route. The winter period sees fewer tourists than summer months, making it easier to secure seats without paying premium prices. Spring and autumn offer mild weather if you prefer not to travel during the coldest weeks or school holidays. Weekday departures often cost less than weekend flights, so compare dates across several days before settling on one.

Full-service carriers Korean Air and Asiana Airlines provide meals and baggage included in most fares. Low-cost options include Jeju Air, Eastar Jet, Jin Air, T'way Air, Air Busan and Air Seoul, which charge separately for extras like checked luggage and seat selection. Thai Smile and China Eastern Airlines typically connect through their respective hubs rather than flying direct on this domestic route.

Arriving late at Incheon International means longer travel time into the city centre compared with Gimpo International. Both airports offer train connections, taxi services and airport shuttles for reaching central Seoul. Gimpo sits just minutes from downtown areas while Incheon requires roughly an hour by express train or bus depending on traffic conditions.
