If your KTX has left, take the ticket or reservation record to a staffed KORAIL station counter promptly. Ask whether any refund remains available, and arrange a valid ticket for the next journey. Do not board a later train assuming that the missed reservation has moved with you. Start with the original booking record, even if you are also searching for another seat.
Check the two times on the original ticket
KORAIL’s published passenger terms, amended April 18, 2025, tie an ordinary refund to the request time and the ticketed journey. Article 14 allows a station claim; direct online/mobile claims for tickets issued through those channels are described before departure. After departure, its standard deductions increase at 20 minutes and 60 minutes, with a full deduction after arrival at the station printed on your ticket, allowing for a train delay. Special products and travel periods can have separate terms. Have KORAIL confirm the rule and amount for your issued ticket.
For example, imagine your ticket ends at Daejeon on a train continuing to Busan. Waiting until the train reaches Busan could miss the relevant deadline. Show staff the departure and arrival fields together, rather than just saying that you missed “the Busan train.” Give the date, train number and purchase channel as well, so staff can find the correct booking.
If an app offers a return function, keep its completion result. An error screen or a tapped button is not a completed refund. If it cannot retrieve or return the ticket, go to the counter instead of spending the remaining time reinstalling it or trying to create another account. Ask staff for the amount, any deduction and the claim record before leaving.
If you will be late but departure is still ahead
Check the original booking’s change option first. KORAIL’s February 2026 announcement describes an eligible same-route change until 30 minutes before the original departure, to trains up to seven days either side of the travel date. Its August integration announcement also describes this change service and separate member refund-fee benefits. Neither announcement promises a suitable seat or that every ticket has the same options.
Compare the later train against the journey you need before confirming a change. Then reopen the ticket and check its new train number, date and departure station. If no suitable change appears, ask about cancellation and a fresh purchase before the original departure. Do not assume that a fee waiver described for an eligible member also applies to a guest or third-party booking.
Get a valid next journey, and keep both records
A refund request concerns the missed train; it does not secure a later seat. Search the live timetable or ask the staffed counter about an available service. If online payment fails, show staff the intended route and ask which payment method it can accept. Confirm availability and payment before treating a replacement as booked. The KTX booking guide covers the separate purchase and ticket-confirmation steps.
Keep two results: the decision on the old ticket and the issued ticket for the next train. Check that your new arrival time still works for any onward bus, flight or hotel check-in. A later service is useful only if the rest of the journey can still be completed; do not buy several speculative replacements while the first payment remains unclear.
If the train has not left and the problem is a ticket you cannot retrieve, follow the lost KORAIL ticket guide instead. If the railway delayed or cancelled the train, tell staff that circumstance so it can assess the correct claim, rather than describing it simply as your missed departure.
