What to know first
01
Check your AREX train type
Transit cards work on the All-Stop Train. The reserved-seat Express Train between the airport and Seoul Station needs a separate ticket.
02
Carry Korean won for reloads
Many transit-card sellers and reload machines do not accept foreign-issued cards. Carrying Korean won cash is the most reliable option.
03
When in doubt, call 1330
Call 1330 for multilingual travel and transport help, 112 for police, or 119 for fire and ambulance.
