The return flight from Seoul to Jeju also takes about 1 hour and 15 minutes, so there is no meaningful difference between directions.", "methodology": "Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.", "toolsUsed": [ "flight_schedule" ] }, "q1": { "question": "Are there any direct flights from Jeju Island to Seoul?", "answer": "Yes, there are abundant nonstop flights from Jeju Island (CJU) to Seoul Gimpo (GMP).

Taxis are readily available and comfortable, though slower in traffic. Airport limousine buses serve key districts and hotels, and ride-share services like Kakao T operate, but car rentals are rarely used for city transfers given excellent public transit.", "toolsUsed": [], "references": [ { "url": "https://en.wikipedia.org/wiki/Gimpo_International_Airport", "title": "Gimpo International Airport", "favicon": "https://en.wikipedia.org/static/apple-touch/wikipedia.png", "time_published": "2026-07-20T00:34:01Z" }, { "url": "https://en.wikipedia.org/wiki/Gimpo_International_Airport_station", "title": "Gimpo International Airport station", "time_published": "2026-06-18T01:18:13Z" }, { "url": "https://airport.kr/bbs/ap_en/937/138233/artclView.do", "title": "K2Web Wizard", "time_published": "2024-10-16T00:00:00Z" }, { "url": "https://www.airport.kr/ap_en/1490/subview.do", "title": "International Incheon Airport", "time_published": "2026-01-22T00:00:00Z" }, { "url": "https://en.wikipedia.org/wiki/Gimpo%20International%20Airport%20station", "title": "Gimpo International Airport station", "time_published": "2025-07-02T14:13:16Z" } ], "methodology": "Airport details are drawn from the sources listed with this answer, primarily the airport operator's official website along with airline, lounge-operator and transit-authority pages, collected by our research process and refreshed periodically.
