How much is the airport train, exactly?
The AREX all-stop is ₩4,150 from Terminal 1 and ₩4,750 from Terminal 2. Those fares were checked on 29 July 2026 and the guide shows how long ago that was, so you can judge whether to re-check. The Express is faster — about 43 minutes from Terminal 1 — but costs more and runs less often. If your stay is near a station the all-stop is usually the better trade.
