The return flight from Jeju to Seoul takes roughly the same amount of time. There are no layover flights on this domestic route, as nonstop service is plentiful and efficient across multiple airlines." }, "q1": { "question": "Are there any direct flights from Seoul to Jeju Island?", "answer": "Yes, there are abundant nonstop flights from Seoul Gimpo (GMP) to Jeju (CJU). Seven airlines — Asiana, Jeju Air, Korean Air, Eastar Jet, Air Busan, Jin Air, and WE — operate the route daily, together offering over 200 departures every day from early morning through late evening, so you can fly any day of the week without a layover.", "methodology": "Airlines and weekly frequencies are compiled 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).

Both Seoul and Jeju Island are part of the same country, so travel between them does not involve crossing international borders. However, if you are a foreign national visiting South Korea, you must already have the appropriate visa or entry permit to be in the country. Once legally admitted, domestic travel, including to Jeju Island, is unrestricted. Note that Jeju Island has a special visa-free policy for certain nationalities arriving directly from abroad, but that does not apply to domestic flights from Seoul." }, "q3": { "question": "What are the ground transportation options in Jeju Island?", "answer": "Jeju International Airport is about 3 km west of downtown Jeju City. Taxis are available outside the terminal and offer the fastest door‑to‑door ride (roughly 10–15 minutes). Public buses are the most‑used option, with frequent city and limousine services connecting the airport to major hotels and neighborhoods across the island. Ride‑share apps have limited coverage, so taxis and buses are the primary choices.
