Know the two AREX services
AREX has Express and All-Stop trains. The Express Train serves Seoul Station. The All-Stop Train also calls at stations including Hongik University and Digital Media City.
Consider the whole journey
An airport limousine bus or a taxi may suit a different destination or more luggage. Check the current route and your final stop before deciding.
Check before you board
Use the operator’s current timetable and fare information. Services and prices can change; an old screenshot is not a reliable departure board.
Keep the address ready
Save your destination in Korean. Confirm that your route gets you close to your accommodation, rather than only to a familiar station name.
