Jeju Air — what to know before you book

Thinking of flying Jeju Air? Good choice if you want cheap fares around Korea and across Asia. This page gives quick, practical info: where they fly, how luggage usually works, and smart booking moves that save money and hassle.

Where Jeju Air flies and what to expect

Jeju Air is best known for frequent trips between the mainland and Jeju Island, plus many short-haul international routes across East and Southeast Asia. Expect single-aisle Boeing 737 jets, mostly used on routes under six hours. Flights are straightforward: limited onboard extras, fast turnarounds, and lots of economy seats. If you want a seat with extra legroom, you’ll usually pay extra when you pick seats during booking.

Want to fly from Seoul to Busan or to Tokyo, Manila, Bangkok, or Taipei? Jeju Air often has competitive fares on those routes. They run seasonal deals, so keep an eye on sales if your dates are flexible.

Booking, check-in and saving money

Book early for the lowest prices. Low-cost carriers like Jeju Air price seats in bands: the cheapest fares vanish fast. Use the airline’s website or app for the best seat maps and add-on options. Sign up for email alerts and follow their social accounts — flash sales happen often.

Check-in online to skip queues. Online check-in usually opens 48 hours before departure (times can change by route), so set a reminder. If you need to change or cancel, fees apply and differ by fare class — read the fare rules at checkout before paying.

Want to avoid surprise fees? Add baggage, seat selection, and other extras at booking. Buying add-ons in advance is almost always cheaper than paying at the airport.

At the airport, arrive early. Low-cost carriers often use busy slots and have strict cutoffs for check-in and boarding. Bring printed or digital boarding passes and the right travel documents for your destination.

Final tip: if you travel with a lot of luggage or want flexibility, compare the total cost (fare plus bags and seats) with full-service airlines. Sometimes a slightly higher base fare gives better value after extras.
