GMP–CJU Quick Facts
Frequently Asked Questions
Seoul Gimpo to Jeju: Korea's Domestic Air Bridge
GMP–CJU is one of the world's highest-volume air corridors, connecting the South Korean capital's inner airport to the country's premier island resort destination. With nine carriers and nearly 470 weekly departures, the route operates as a near-continuous shuttle. Flight time is 55 minutes. Jeju Island has no inter-city road or rail connection to the mainland, making aviation the only practical transport option.
Carrier Competition and Fares
Jeju Air, Jin Air, and T'way dominate the low-cost segment, while Korean Air and Asiana serve the full-service market. The intense competition keeps base fares low, though prices spike significantly during Korean national holidays. Chuseok (September) and Seollal (January/February) see the route sold out weeks in advance. Gimpo's closer proximity to Seoul's city center makes it the preferred airport over Incheon for domestic Jeju travelers.
