If you need a KTX train during the 2026 Chuseok holiday, start with KORAIL’s official English website and open the current Chuseok reservation notice before searching for a normal ticket. Holiday sales can follow a special process, so the ordinary “one month ahead” rule should not be treated as the only booking schedule.
Chuseok falls on September 24–26 in 2026. Demand spreads beyond those three dates, so prepare your route, passenger details, payment method, and a backup bus or SRT plan before seats open.
Check the official 2026 Chuseok notice first
Open KORAIL’s English notice page, select the 2026 Chuseok reservation notice, and follow the dates and train coverage shown there.
KORAIL posted its 2026 Chuseok holiday train reservation notice on August 14, 2026. The official English booking site also displays a Chuseok reservation banner. Because holiday instructions can be updated, use the live notice rather than a social-media screenshot or an old blog post.
The Korea Tourism Organization lists September 24–26 as the official 2026 Chuseok holiday. Many people travel before the first holiday and return after the last one, so search the exact travel date instead of assuming only the three public-holiday dates will be busy.
You should see the official Chuseok notice, the English reservation page, and a clear search form for your departure date and stations. If the special notice gives different instructions, the notice takes priority.
Prepare the route before the booking window
Write down your exact departure station, destination station, acceptable time range, and one alternative station before you begin.
“Seoul” can mean Seoul Station, Yongsan, Cheongnyangni, or another station depending on the line. Other cities may also have more than one useful rail stop. Check the route before the busy sale.
Prepare the passenger information requested by the form and keep the same spelling throughout the purchase. Enter card information only on the official KORAIL domain. If translation breaks the form, return to the official English interface.
Choose a first-choice train, an earlier or later train, and a backup date. A flexible time range is more useful than repeatedly refreshing one sold-out departure.
Book through the official English reservation page
Search the route on KORAIL’s official English ticket page, select a train only after checking the date and stations, then save the completed reservation details.
KORAIL states that ordinary tickets can generally be purchased up to one month before departure. Chuseok is a special period, so use the holiday notice for the opening schedule. A missing train may not yet be open or may already be sold out.
After payment, open My Reservation using the same information entered during purchase. Confirm the passenger, departure date, departure station, destination, train number, and departure time. Save access to the reservation where you can reach it without searching your email at the station.
Do not pay an unknown reseller that claims it can guarantee a sold-out Chuseok seat. Verify the seller and refund rules, and prefer the official KORAIL channel.
What to do when KTX is sold out
Change one variable at a time: departure time, nearby station, travel date, train type, and finally the transport operator.
First search earlier and later departures. Next check whether a nearby station creates a practical route. Then review other train types in the official search. Canceled seats may return, but availability is not guaranteed.
SRT is a separate high-speed rail option with its own reservation system and station network. Read our SRT guide for travel across Korea before comparing it with the complete KTX guide for first-time travelers. If rail does not work, use our express bus terminal guide to build a bus backup.
Travel-day checks
Recheck the station and departure time the day before, arrive with enough time to find the platform, and keep the reservation accessible.
Holiday crowds can make stations busier than usual. Verify whether your train leaves from Seoul Station, Yongsan, Suseo, or another station; these are not interchangeable. Use live operator information for delays or platform changes.
If you cannot retrieve the booking, open KORAIL’s My Reservation page and enter the same purchase information. For an unresolved ticket issue, use the contact channel displayed on the official English website rather than accepting instructions from an unofficial account.
Official holiday notice → prepared route options → official reservation → My Reservation check → SRT or express-bus backup.
Frequently asked questions
Use the live KORAIL notice for sale timing and the official reservation record for your final travel details.
When is Chuseok in Korea in 2026?
The official holiday is September 24–26, 2026. Travel demand can extend to the surrounding days.
Can I book a normal KTX ticket one month ahead?
KORAIL gives one month as the general advance-purchase period, but Chuseok can use a special reservation process. Check the 2026 holiday notice first.
Is the English KORAIL website official?
Yes. Use the KORAIL global English site and confirm that the address remains on the official KORAIL domain.
What if my foreign card does not complete payment?
Retry only through the payment options displayed by KORAIL, check whether your bank blocked the transaction, and do not send card details to a third party.
Is a KORAIL Pass a guaranteed Chuseok seat?
No pass should be treated as a guarantee of a specific sold-out seat. Check the pass rules and reserve an eligible seat through the official system.
What is the safest backup if KTX is sold out?
Compare SRT where the route fits, then check official express or intercity bus options. Confirm the departure terminal because Seoul has multiple bus terminals.
Confirm the booking or take the next action
Your plan is complete only when My Reservation shows the correct passenger, date, stations, train, and time—or when a confirmed backup ticket is in place.
If the reservation is missing, re-enter the same purchase information and check the payment result. If no KTX seat is available, stop repeating the identical search and move through your prepared time, station, date, SRT, and bus alternatives. This produces a real travel plan instead of a hopeful refresh loop.
