KTX Guide for Korea Travelers

KORAIL tickets can usually be checked and purchased up to about 1 month before departure on the official KORAIL booking page. Popular routes such as Seoul to Busan can sell out during weekends, holidays, and peak travel seasons, so booking early is safer.

The fare depends on the route, train type, seat class, date, and departure time. Use the official KORAIL timetable and fare page before you pay. Do not rely only on old blog prices because train fares and seat availability can change.

The KORAIL English booking site supports credit-card payment. For foreign visitors, this is usually the easiest online method. However, overseas card approval can depend on your card issuer, security verification, and browser/app conditions. Bring a backup card or be ready to buy at the station counter if online payment fails.

Yes, if seats are still available. You can use a station ticket counter or ticket machine. For foreign visitors, the staffed ticket counter is the safest choice if you are unsure about card payment, station names, or seat options.

No. You do not have to pay only in cash. KORAIL online booking mainly uses card-based payment options. At stations, payment options may include card or cash depending on the counter or machine. Carrying some Korean won is still helpful as a backup, especially if your overseas card is declined.

If you use a mobile ticket, keep the ticket screen available on your phone and show it when asked. If you have trouble using a mobile ticket, ask at the station counter before boarding. Always keep your ticket from departure to arrival.

Yes, but timing matters. Before departure, self-issued tickets can usually be refunded through the KORAIL website or KorailTalk app. After departure, refund requests are generally handled at the station, and refund fees may apply. Refund rules can change, so always check the official page before canceling.

If a credit-card ticket is fully refunded on the same day before the daily processing cutoff, cancellation may be reflected quickly. If refunded later, the card refund can take several business days depending on the card company. Overseas cards may take longer.
