Choose the ticket type before searching trains
A point-to-point KTX ticket is often simpler for one or two journeys, while a rail pass only makes sense after comparing the pass price with the exact trains you plan to take. A pass does not guarantee a seat: reserve each train separately, especially on Friday evenings, Sundays, and public-holiday periods.
Booking details that prevent mistakes
Search with the station name, not only the city name. Seoul-area departures may use Seoul, Yongsan, Cheongnyangni, or Suseo, and SRT is a separate operator from Korail. Confirm the operator, station, departure date, passenger name, and refund deadline before payment. Buy through Korail or an authorized channel and keep the booking number available offline.
