Route data is updated regularly from official airline schedules. On-time performance data comes from recent airport delay snapshots.
Jeju International Airport operates from a single terminal building with separate domestic and international wings. The airport is compact and walkable. Check-in to gate typically takes under 30 minutes outside peak periods. A second airport is under construction on the east side of the island, expected to open in the late 2020s.
First departures from Jeju typically begin around 6–6:30am, with the last flights arriving in Seoul around 10–11pm. The high frequency means departures every 5–15 minutes during daytime peaks. Standby lists can be accommodated on most off-peak departures given the shuttle-like operations.
Yes. Jeju City has regular city bus connections from the airport. Route 600 runs to Jeju City center (15 min, ₩1,200). Limousine buses connect to major hotels and resort areas on the island's south and east coasts (60–90 min, ₩5,000–8,000). Taxis are metered and relatively inexpensive for island distances.
Jeju to Seoul Gimpo: Return Corridor from Korea's Island
CJU–GMP operates at nearly identical frequency to the outbound direction, reflecting the symmetrical nature of leisure and business travel between Jeju and Seoul. The 451 weekly departures are spread across nine carriers including Korean Air, Asiana, Jeju Air, Jin Air, Air Busan, and T'way, creating competition that keeps the route affordable for the millions of Korean domestic travelers who visit Jeju each year.
Connection Patterns at Gimpo
Seoul Gimpo Airport (GMP) primarily serves domestic routes within South Korea and short-haul international routes to Tokyo Haneda, Beijing Capital, Shanghai Hongqiao, and Taipei Songshan. Travelers continuing internationally from Jeju typically need to connect at Incheon (ICN) rather than Gimpo. There is no direct rail link between Gimpo and Incheon, though the AREX and airport limousine buses provide connections.
