KTX Tickets in English: Where to Buy, How Late You Can Book, and What a Refund Costs
The Same Site Gives Two Answers to "How Early Can I Book?"
Ask how far ahead you can buy a KTX seat and KORAIL's English site answers twice. The Ticketing Guide says tickets open two months before the departure date. A notice three clicks away says one month — because that one is about seats reserved with a KORAIL PASS, not about buying a ticket outright. Neither page mentions the other.
That gap is the shape of this whole subject. The English pages are accurate and free of jargon, but they are scattered, and the sentence that costs you money is rarely on the page you landed on. Everything below was read off korail.com's English pages on 1 November 2026: the Ticketing Guide, the Book KORAIL Pass page, MY TICKET, and the notice board. KORAIL's call centre is +82-1599-7777, 08:00–20:00.

Where You Can Buy, and Which Counter Stays Open Longest
Source: korail.com, KORAIL Ticketing Guide (captured Nov 1, 2026)
Four channels sell tickets: the KORAIL website, the KORAIL+ mobile app, ticket vending machines, and train stations. The guide adds a parenthesis worth holding on to — not available at subway stations. A Seoul Metro booth cannot sell you a KTX seat.
If you have searched whether you can simply turn up and buy at the station, the answer is on the same line, and it is the most forgiving of the four. Station counters sell until departure. So does the website. Ticket vending machines stop 10 minutes before departure — the only channel that closes early, and the one a traveller sprinting through the concourse is most likely to reach for.
Payment online is one sentence long: "You can pay by credit card." No wallet, no bank transfer, no cash option is listed for the website.
One habit is worth forming before you book. KORAIL posts service interruptions on the English notice board, and foreign-card payment is one of the things that gets taken down. On 21 August 2026 the board carried "Temporary Suspension of Foreign Credit Card Payments" for a maintenance window of 24 August 2026, 03:00–05:00 KST. That particular window is long past, and nothing suggests it is a standing restriction. The point is that it was announced there and nowhere a traveller would otherwise look. If you are booking late at night, the notice board takes ten seconds to check.
Your Ticket Is an E-mail Address and a Number, Not an Account
Source: korail.com, MY TICKET (captured Nov 1, 2026)
There is no sign-up on the English site. You buy with an e-mail address and a password you invent at the counter, and those two strings are the only thing standing between you and your reservation afterwards. MY TICKET splits into three tabs — Rail Tickets, KORAIL PASS, RECEIPT SEARCH — and the guide notes that tickets bought with a KORAIL PASS are authenticated in the PASS tab rather than the first one.
Here the two pages disagree, and it is worth knowing before you invent anything. The Ticketing Guide warns that you must enter your password and e-mail "correctly (including the use of uppercase and lowercase letters)". The password box on MY TICKET is labelled 6~13 digit number. A digit has no case. We cannot tell you from these pages which rule the form actually enforces, so do what the guide itself suggests in the next sentence: write down exactly what you typed, character for character, before you leave the payment screen.
The second radio button is the quiet safety net. If the password is gone, Credit Card Number will find the booking instead — the card you paid with doubles as a recovery key. Travelling with a card you will still be carrying on departure day is therefore not a small detail.
What a Refund Costs, and the One Line You Cannot Cross

Cancelling before departure is self-service: the MY TICKET menu on the website for web and home tickets, the KORAIL+ app for mobile tickets. What it costs depends on two things, and the second one surprises people — the day of the week.
Monday to Thursday. Nothing at all until three hours before departure. The table merges the first three columns into a single "No Cancellation Fee" cell that runs from two months out all the way to the three-hour mark. In the final three hours, 5%.
Friday to Sunday and bank holidays. A minimum cancellation fee applies from the moment you book — there is no free window. Then 5% from a day out, 10% from 24 hours to 3 hours, and 20% in the last three hours. A Saturday ticket cancelled the night before costs four times what the same cancellation costs on a Wednesday.
Then the train leaves, and the rules change shape rather than just scaling up. The after-departure columns sit under a heading printed in red: refundable ONLY at the ticket office of a KORAIL station. The website stops being an option. Inside 20 minutes the penalty is 15% on a weekday and 30% at the weekend; past that the two rows merge again and the day of the week stops mattering — 40% up to an hour late, 70% from an hour until the train's scheduled arrival.
After the arrival time printed on the ticket, there is no refund at any counter.
Two more provisions apply once you are aboard. If you get off early, KORAIL refunds the unused stretch after deducting a penalty and the portion already travelled. If you want to ride past your ticketed destination, pay the train attendant and buy a new ticket before you pass it; the guide's word for doing it afterwards is "illegal passenger", with additional fares collected on top of the normal fare.
Losing the ticket is its own category, and it is harsh: you cannot stay on the train, change the journey, or claim a refund. There is a route back only if the purchase can be confirmed by credit card — you pay again for a re-issued ticket, ask KORAIL to confirm the lost one went unused, and collect a refund at a station counter minus the minimum penalty. The guide states this does not apply to standing or non-reserved seats, which have no designated seat to verify.
KORAIL PASS: Two Seats a Day, and No Way Back After Day One
Source: korail.com, Notice "PASS details" (captured Nov 1, 2026)
The KORAIL PASS is the foreigner-only product, sold as FX in 2, 3, 4 and 5-day lengths, adult or child. The booking page asks for your start date in DD-MM-YYYY order, which is worth reading twice if you write dates the American way.
Most English write-ups compare the pass to point-to-point tickets on price. The pages above suggest two other columns matter more.
It reserves at most two seats per person per day. The notice is explicit: up to 2 seats per person per day, and only 1 if you are using a transfer ticket. Beyond that allowance the pass covers standing and non-reserved seats — on KTX including KTX-Sancheon and KTX-Eum, and on ITX-Cheongchun, ITX-Saemaeul, Saemaeul, Mugunghwa, Nuriro and regular tourist trains. A three-leg day is not three reserved seats.
It cannot board SRT, the metropolitan subway, or special tourist trains. That line matters at the search stage, not at the gate. If a route you are pricing comes back on SRT, the pass does not cover that train, whatever the fare comparison said.
Seat reservations on a pass also open later and close earlier than ordinary tickets: one month ahead rather than two, and the website stops 20 minutes before departure rather than at departure. Vending machines and station counters keep their usual hours.

Then the three warnings stacked above the booking form, of which the last is the one to weigh. All details must match the passport exactly. Nothing — pass type, passenger type, personal information — can be changed after purchase. And: there is no refund fee up to the day before the start date, but refunds are not possible after the starting date.
Set that against the ticket table. A Monday ticket cancelled three hours before departure costs nothing. A pass abandoned on the morning of day one costs all of it. The pass is the better buy when the itinerary is settled, and the worse one when it is not — and that is a judgement about your plans, not about the fare.
What These Pages Do Not Answer
They carry no fares. The Book KORAIL Pass page asks you to choose a pass type before it will show a price, and the Ticketing Guide quotes none at all. "Minimum cancellation fee" is named but never given as a number, so the cheapest weekend cancellation cannot be worked out from the published rules.
They do not say which foreign cards clear. "You can pay by credit card" is the entire payment specification, and the only evidence that cards from abroad are handled separately is that a notice once suspended them for maintenance. They do not resolve whether the booking password accepts letters, as noted above. And beyond the single exclusion line, they say nothing about SRT — what it is, who runs it, or where it departs from — so do not read that line as a comparison.
This article does not reproduce the seat-selection or payment screens. KORAIL's reservation search is protected against automated access and we did not work around that; the captures above are the published guide, notice and lookup pages, which are the parts that decide what a booking costs.
One date is worth checking yourself. The "PASS details" notice is stamped 2024-11-01, so the one-month window and the two-seat allowance have stood for a while — but a notice is easier to supersede than a guide page. If a trip depends on either number, confirm it on the day with the call centre on +82-1599-7777, 08:00–20:00.
