70 places reachable without changing, across 1 terminal and 1 airport. 3 of them you can reach more than one way — where the mode is a genuine choice rather than the only route. You do not board anything in Jeju City itself; each one below says how far out it is.
2 places to board, none of them "Jeju City" itself. The distance is from the centre — an airport an hour out is a different journey from one thirteen kilometres away, and folding that into a flight time is the false claim this site exists to avoid.
3 places reachable from Jeju City more than one way. Everywhere else, the mode is not a decision — it is the only way there.
Every destination from Jeju City placed by compass bearing. Not a map — the angle is the only geography kept, so an empty quarter means nothing goes that way, not that it is sea.

If you are travelling well outside August 2026, confirm with the operator before you plan around it.
