Best Time and Tips to Book Gimpo Jeju Flights

The Gimpo-Jeju route, known for its high annual passenger volume exceeding ten million, is experiencing reduced seat availability due to airline mergers. Although flight frequencies remain consistent, the actual number of available seats has decreased, particularly with low-cost carriers operating aircraft with fewer seats.

Booking Gimpo-Jeju flights 1-2 months in advance typically offers lower prices. Off-peak seasons are generally March-April, late May-June, and September-November, while peak seasons include late July-August and holiday periods. Tuesdays, Wednesdays, and Saturdays are often cheaper departure days, and Sundays and Tuesdays are frequently the best days to purchase tickets. Fuel surcharges fluctuate monthly based on the ticketing date, not the travel date, so it is crucial to check them at the time of booking.

When booking, it is essential to review each airline's fare classes and baggage policies. For instance, Jeju Air's 'FLY' fare does not include checked baggage, which can lead to additional fees at the airport. Opting for the 'FLYBAG' fare is advisable if you plan to check luggage. Completing mobile check-in beforehand can also save significant time at the airport.
