Korail opened Chuseok 2026 train bookings on September 7, 2026, and general booking runs through September 11.
A Korail Pass stays valid for the holiday, but the pass covers the fare only — on a full train it does not give you a seat.
This post covers the booking dates, the September 11 window for foreign non-residents, and what to do when every seat is gone.
Korail Pass seat reservation: what changes during Chuseok 2026
| Sept 3-4 | Priority booking for seniors 65+, registered disabled, national meritorious persons, and pregnant women |
|---|---|
| Sept 7-11 | General booking, split by route and train type, 07:00-13:00 each day |
| Sept 11 | Booking opens to foreign non-resident accounts |
| Sept 12, 00:00 | Payment window opens |
| Sept 15 | Payment deadline for general bookings — unpaid seats auto-cancel |
| Sept 23-27 | Chuseok holiday travel period |
Chuseok 2026 runs five days, from September 23 to September 27.
Korail split general booking across five days, September 7 to 11, instead of opening everything at once.
Each day covers a different set of trains: September 7 for all regular trains (ITX-Saemaeul, Mugunghwa), September 8 for KTX on the Gyeongjeon, Gangneung, Donghae, Jungang, and Jungbu-naeryuk lines, September 9 for Honam and Jeolla KTX, September 10 for KTX departing or arriving at Suseo, and September 11 for Gyeongbu-line KTX.
Some routes appear on two days — Seoul to Dongdaegu KTX is bookable on both September 8 and September 11 — so a sold-out first day is not the end.
Booking happens only online, through the Korail+ app and the dedicated holiday booking page; station counters are suspended during the window.
Once in, a general reservation must be completed within 3 minutes.
Payment opens at midnight on September 12 and general bookings must be paid by September 15, or the seat is released to waitlist applicants.
There is a limit of 12 tickets per person in total, with at most 6 one-way per transaction.
Chuseok 2026 booking results: 84% reservation rate and added seats
Korail’s Chuseok 2026 booking window closed with an 84% reservation rate — 1.8 million tickets sold between September 3 and 11.
That is 21 percentage points higher than last year’s Chuseok rate of 63%. September 1, 2026 marked the first holiday under the KTX-SRT integrated operation, and the integrated booking system was applied. After integration, average daily seat supply rose 6.7% from 254,000 to 271,000 seats (September 1–14), and daily ridership on major routes grew 12.1% from 272,000 to 305,000.
| Figure | Number |
|---|---|
| Reservation rate | 84% (up 21pp from 63% in 2025) |
| Tickets sold (Sept 3–11) | 1.8 million |
| Daily seat supply after integration | 271,000 (+6.7%) |
| Daily ridership, major routes | 305,000 (+12.1%) |
| Late-night metro trains, Sept 26–27 | 24 extra runs on 5 lines incl. Line 1 |
Competition was fierce — some Seoul–Dongdaegu segments sold out and one buyer on September 7 drew a queue number in the 110,000s. Secondhand apps responded with carpool and booking-agency listings. Unsold seats and canceled tickets keep opening until departure time, so a sold-out first pass is still not the end.
Does the Korail Pass guarantee a seat during Chuseok?
No — the pass covers the fare, not the seat.
On Chuseok trains, a separate seat reservation is required for every train you board, and reservations are free for pass holders.
Popular routes such as Seoul–Busan and Seoul–Gyeongju sell out weeks ahead, even for travelers whose fare is already paid.
A pass holder who misses the booking window is left checking daily for cancellations or standing on a sold-out train.
The pass is tied to your passport, so carry it while riding — conductors check it onboard or at the platform.
The Seoul–Busan KTX one-way fare is about ₩60,000, so a round trip runs about ₩120,000; that is the baseline a multi-day pass has to beat on a multi-city itinerary.
When can foreign non-residents book?
Foreign non-resident accounts can book from September 11, 2026 — four days after local accounts opened on September 7.
By then Gyeongbu-line KTX seats have already been open to locals since that same morning’s route-based schedule, so the practical move is to have your account and routes ready and enter the page right at the opening minute.
The holiday page uses a waiting-queue system, and refreshing (F5) resets your queue number, so enter once and wait.
A Korail Pass is bought in advance as a voucher through the Korail global site or resellers like Klook, then activated via the KorailTalk app or a station foreigner help desk — activation sets the start date, so do not activate before your actual first travel day.
Travelers who cannot book online can call the dedicated holiday line, 1544-8545.
KTX sold out? Cancellation watch and SRT fallback
Two fallbacks work when everything is gone.
First, the cancellation watch: tickets unpaid by the September 15 deadline auto-cancel and are assigned sequentially to waitlist applicants, so checking the booking page daily around that date turns up real seats.
Second, switch operators: SRT remains an alternative, and travelers who miss KTX also fall back to intercity buses.
One thing to keep straight: the Korail Pass does not cover SRT or city subways — Korail trains only.
If you also need the Seoul or Busan metro, the 2026 Korail Pass Plus adds a NAMANE prepaid transit card for about ₩8,000 on top of the standard pass, bought at NAMANE kiosks or the official Pass+ site.
Avoid resellers outside official channels — buying a scalped ticket risks losing the full amount, and Korail runs undercover checks and a reporting desk against illegal resales.

FAQ
Q. Does the Korail Pass guarantee a seat during Chuseok?
No. The pass covers the fare; each train still needs a separate — free — seat reservation, and holiday trains sell out even for pass holders.
Q. When can foreign non-residents book Chuseok KTX?
From September 11, 2026, four days after local accounts opened on September 7.
Q. What can I do if every Chuseok KTX seat is sold out?
Check daily around the September 15 payment deadline, when unpaid seats are released to the waitlist, or switch to SRT or intercity buses — note the pass does not cover SRT fares.
Q. Can I ride Korail standing with a Korail Pass during Chuseok?
There is no official Korail announcement confirming standing-only boarding rules for Chuseok. Korail has stated that boarding without a valid ticket or extending beyond your booked section incurs an extra charge equal to the original fare, so riding without a seat reservation is not free.
