Chuseok falls on 25 September. As of the day this was written — 12 August 2026 — KORAIL has not yet posted its holiday ticket-release notice. But something else is already fixed regardless of that notice: what it costs you to cancel. And that figure is different on a holiday than on a weekday.
1. Cancelling a holiday ticket is never free, even a month out. Monday to Thursday, the penalty is zero right up to three hours before departure. Friday to Sunday, public holidays and the two big holidays carry a flat minimum penalty from a month out.
2. Three hours before departure is the cliff. At that same moment a weekday ticket costs 5% and a holiday ticket 20%. On a 100,000 won fare that is 5,000 against 20,000 won.
3. The Act allows a surcharge of up to thirty times the fare. Article 10(1) of the Railroad Business Act says “up to thirty times” — while the schedule KORAIL actually applies tops out at ten times.
The same cancellation costs different amounts by day of week
KORAIL’s published refund penalty table for standard tickets has two rows. One is Monday to Thursday; the other is Friday to Sunday, public holidays, and Seollal and Chuseok. A Chuseok ticket sits on the lower row.
| Cancelled | Mon–Thu | Fri–Sun, holidays, Chuseok |
|---|---|---|
| 1 month to 2 days before | Free | Minimum penalty |
| 1 day before | Free | 5% |
| Same day, to 3h before | Free | 10% |
| 3h before, to departure | 5% | 20% |
| To 20 min after departure | 15% | 30% |
| 20 to 60 min after | 40% | 40% |
| 60 min after, to arrival | 70% | 70% |
The table does not say what the “minimum penalty” is. That appears one line below the group-ticket table underneath it: “the minimum penalty is 400 won”. So cancelling a holiday ticket a month in advance still costs 400 won — a slot that would be free on a weekday.
Converted to a 100,000 won fare
Percentages are hard to feel, so here they are applied to a 100,000 won fare. These are the table’s own rates, multiplied out.
| Cancelled | Mon–Thu | Holiday ticket | Gap |
|---|---|---|---|
| 1 month to 2 days before | 0 | 400 won | 400 won |
| 1 day before | 0 | 5,000 won | 5,000 won |
| Same day, to 3h before | 0 | 10,000 won | 10,000 won |
| 3h before, to departure | 5,000 won | 20,000 won | 15,000 won |
| To 20 min after departure | 15,000 won | 30,000 won | 15,000 won |
| 20 to 60 min after | 40,000 won | 40,000 won | — |
| 60 min after, to arrival | 70,000 won | 70,000 won | — |
So “book it now and decide later” costs more over a holiday than on an ordinary week. The three-hour line is where it bites: crossing it takes 20% in one step, four times the weekday figure. If a trip is going to fall through, cancelling on the morning of departure is materially cheaper than letting that line pass.
Twenty minutes after departure, the two rows become one
The last two columns are identical for weekdays and holidays — 40%, then 70%. That is not a holiday surcharge; it is what applies once the train has already left. After departure, refunds are processed at a station counter only.
One exception: a KTX ticket bought in the KORAIL Talk app can be refunded in the app up to 10 minutes after departure, once it is confirmed you are not aboard. And once the arrival time at your destination has passed, no refund can be requested at all.
One more trap: if you pay but never issue the ticket, the system cancels it automatically — and that is not a clean cancellation. The after-departure penalty applies. Holding a ticket and forgetting it is the most expensive outcome available.
This table has to be looked at, not scraped
Worth stating plainly: we nearly got this table wrong. Pull the text out of KORAIL’s page and you get seven column headers but only five values per row. Read that literally and you conclude that holidays are somehow cheaper after departure — which is false.
Zooming into the rendered page settled it. The “Free” cell on the Monday-to-Thursday row spans the first three columns, and the 40% and 70% cells are shared between both rows. Nothing was missing; the cells were merged. The table in this article unmerges them, one window at a time.
The surcharge: the Act leaves room for thirty times the fare
Over a holiday, when even standing room sells out, “just board and sort it out inside” is a tempting thought. What that costs is written in statute.
Railroad Business Act, article 10 (Collection of Surcharges) (1) Where a passenger uses a train without paying the proper fare or charge, the railroad business operator may collect, in addition to the fare for the section travelled, a surcharge of up to thirty times that amount.
| Situation | Surcharge |
|---|---|
| Boarding without a valid ticket · using a screenshot or photo of one · using another train’s ticket | 1× |
| A child aged 6 or over travelling without a ticket | 1× |
| Travelling beyond the section you hold | 1× |
| Avoiding or refusing a ticket inspection | 2× |
| Using a discount fare or seat you do not qualify for (KORAIL’s example: a 60-year-old on a senior ticket) | 10× |
| Holding a discount fare but not producing the required proof | 10× |
The multiple sits on top of the fare. A 10× surcharge means paying eleven fares in total — 550,000 won on a 50,000 won section. And note that a child travelling on an infant ticket lands in the 10× row: that is not a place to economise on a child’s ticket.
KORAIL does not set these figures by itself
The next paragraphs of the same article set out the procedure.
Same article, paragraph (3) Where an operator intends to collect a surcharge […] it shall determine in advance the basis for calculating it — by the conduct concerned, the type of train and the section operated — and include it in the railroad business tariff under article 11 and file it with the Minister of Land, Infrastructure and Transport.
Article 11 (Railroad Business Tariff) (1) A railroad business operator shall determine a railroad business tariff and file it with the Minister. The same applies to any change.
So neither the penalty table nor the surcharge table is a notice a company simply posts on its website. Both are content carried in a filed tariff. The Minister must respond to the filing within three days (articles 10(4) and 11(3)). The answer to “can they not just change the terms whenever they like?” is in the statute.
And that tariff changed on 1 August
KORAIL’s tariff page currently carries two versions side by side — “current, revised 29 May 2026” and “effective 1 August 2026”. As of 12 August the effective date has passed, yet the May version is still the one labelled current.
So the figures in this article are the ones KORAIL publishes on its guidance pages today, not the result of comparing the two tariff documents line by line. Check the guidance screen again at the moment you cancel.
The release date has not been announced yet
There is no 2026 Chuseok ticket-release notice on KORAIL’s board as of 12 August. What is posted that day is a booking-system maintenance notice. Until the release notice appears, the dependable part is the ordinary purchase rules.
| Item | Rule |
|---|---|
| Normal booking window | From 07:00, one month before departure, until the train leaves |
| Where to buy | Website · KORAIL Talk app · ticket machines · staffed stations · agents |
| Instalments | Card instalments available on payments of 50,000 won or more |
| Refund before departure | Website or app, directly |
| Refund after departure | Station counter (KTX bought in the app: within 10 minutes) |
| Missed the train through a natural disaster | Within 1 year, with documentary proof at a station: 50% refunded |
Note that SRT is run by SR, not KORAIL. It has its own release schedule and its own tariff, so SRT tickets have to be checked there.
Other rules that bite over the holiday itself: expressway toll exemption covers only three of the four holiday days, and if you work through it you can check what holiday work pay comes to. On the shopping side there is this year’s Chuseok grocery prices, and what actually sends people to hospital over the holiday is in the holiday accident figures.

What we could not check
- The tariff documents themselves were not compared. KORAIL posts the “current, 29 May 2026” and “effective 1 August 2026” versions as PDFs; we did not read them line against line. The figures here come from the guidance pages.
- The 2026 Chuseok release schedule. No notice as of 12 August — check KORAIL’s notice board and SR’s separately.
- Priority pre-booking. KORAIL’s menu carries a “holiday pre-booking eligibility” item for veterans, but which entitlements qualify, and by what procedure, we could not verify.
Written as at August 2026. The penalty and surcharge figures were read from KORAIL’s guidance pages on 12 August 2026, and the 100,000 won amounts are those rates multiplied out. Statute is quoted verbatim from the Korean Law Information Center. The two tariff documents, the release schedule and the priority-booking procedure could not be checked. Other everyday calculations are in the calculator collection.
