How to Book Chuseok & Seollal Holiday Train Tickets — Surviving Korea's Booking Wars (Foreigner's Guide)

You open the Korail+ app (formerly Korail Talk) a week before Chuseok and find every Seoul→Busan KTX seat sold out. "There's still a whole week left—why?" Many foreigners panic at this moment. Korea's Chuseok and Seollal holidays have the entire nation traveling home on the same dates, so train tickets aren't released through normal sales—they're distributed via "advance reservation" about a month early, and popular routes & time slots sell out then. If you don't know this structure, you'll miss the booking window entirely.

This guide explains how the holiday advance reservation system works, how foreigners can participate, and realistic ways to get tickets even after sold-out (cancellation hunting, standing tickets, seat+standing combos), plus alternatives when trains don't work out.

First, there's something you need to do right now. Tickets for trains operating from September 1, 2026 onward went on sale starting August 5 at 10:00 AM through the integrated Korail+ app and www.korail.com. However, trains during the special holiday transport period (9/24~27) have traditionally been excluded from this general sale and released only through holiday advance reservation. So if you search now and can't find trains right in the middle of the holiday, it might not be sold out—it might not be open yet (needs official confirmation whether this applies post-merger). Instead, dates around the holiday (9/22~23, 9/28~29) are available now through integrated booking, so check and secure those first, then wait for the advance reservation announcement for the core holiday dates.

First, Which App Do I Need? — Korail+ & SRT App Guide

2026 brings confusion right from the app names due to the Korail-SR merger.

• Korail+ — Your main train booking app. It's not a separate new app but the existing Korail Talk updated and renamed, so if you already have Korail Talk installed, just update it in the store. If starting fresh, search "Korail+" or "코레일+" in the App Store or Play Store (developer listed as Korea Railroad Corporation / 한국철도공사).
• Integrated website www.korail.com — For PC and mobile web booking. The old address (letskorail.com) now redirects here automatically.
• SRT app (SRT - 수서고속철도) — Trains departing from Suseo Station are also searchable and bookable in Korail+ starting September 1 (when the SRT name changes to KTX-Sancheon). Note that KTX-Sancheon has also been the name of a different high-speed train operating since 2010, so search results may mix old info. When looking for Suseo departures, identify by departure station (Suseo) rather than train name. The old SRT app will only support non-member booking after September, without integrated member benefits like mileage or discounts. Holiday advance reservations require railway membership, so the SRT app won't work for that—use Korail+ app or www.korail.com.

Throughout this guide, booking channels are unified as Korail+ app and www.korail.com.

When is the 2026 Chuseok Holiday?

The 2026 Chuseok day itself is Friday, September 25. The statutory public holidays are September 24 (Thu) ~ 26 (Sat), three days, and Sunday 9/27 follows right after, creating a practical four-day weekend September 24~27. No substitute holiday applies this year.

During this four-day span, millions move between Seoul and provincial areas. So KTX, ITX-Saemaul, and Mugunghwa-ho seats for this period are allocated through holiday-specific advance reservations before the general booking window opens, and popular routes & times essentially sell out on advance reservation day.

This Year's Conditions Are Slightly Better

Chuseok 2026 is the first major holiday with expanded capacity. The September 1 high-speed rail integration adds 23 weekday and 26 weekend runs, supplying about 116,000 additional seats per week, with Suseo Station departures increasing by roughly 30%. Fares also drop an average 10% from KTX baseline (Seoul~Busan 59,800 KRW → 54,400 KRW, Yongsan~Gwangju Songjeong 46,800 KRW → 42,000 KRW, a 4,800 KRW reduction) (per Korail 2026-08-05 announcement).

However, don't misunderstand: this is regular capacity increase from the merger, not holiday-specific extra trains. How many additional special trains will run during the Chuseok transport period hasn't been announced as of 2026-08, so don't assume "tickets will be plentiful this year" and relax. (Needs official confirmation)

Holiday 'Advance Reservation' Is Completely Different from Regular Booking

Normally, train tickets become available as departure dates approach and anyone can buy them via app, website, or station counter. Holiday tickets work differently. Key differences in table form:

Both ticket limits and priority allocation percentages change every year via announcement. If you have a large group, don't have one person try to buy everything—have companions each complete member registration and integrated member conversion in advance.

Some years divide advance reservation by route groups on different days (e.g., Gyeongbu line group one day, Honam/Jeolla line group another). Check which day your route opens in the announcement.

For actual example: 2026 Seollal (Lunar New Year on Feb 17) had priority booking Jan 15~16, general booking Jan 19~21 per Korail announcement—a typical pattern of opening about a month before the holiday. Dates and duration vary year to year, so re-check that year's announcement.

How Do I Know the Advance Reservation Schedule?

Check this first — September integrated booking already started. Tickets for trains operating from September 1, 2026 onward went on sale August 5 at 10:00 AM through Korail+ app and www.korail.com. However, as mentioned, trains right in the middle of the holiday (9/24~27) likely split off into holiday advance reservation. So right now, check dates around the holiday first, secure any available seats, and wait for the advance reservation announcement for core holiday dates.

Next comes holiday advance reservation. Advance reservation dates aren't fixed but announced annually by Korail and SR. Typically booking opens about a month before the holiday, with announcements 1-2 weeks prior. Following previous patterns, for 2026 Chuseok (9/25), announcements and booking would likely happen late August ~ early September, but as of 2026-08, confirmed dates haven't been officially announced yet. (Needs official confirmation)

⚠️ This year may not follow previous patterns. Korail announced expanding ticket availability from 1 month to 2 months before departure, but reported implementation is October 2026, so it likely won't apply to September Chuseok yet (implementation timing to be separately announced). Plus this Chuseok is the first major holiday post-merger, so it's uncertain whether holiday advance reservation will operate as in previous years. Thus the "late August ~ early September" above is an estimate from past patterns, not a confirmed schedule. (Needs official confirmation)

⚠️ Don't trust booking date tables circulating online. Blogs and travel sites list different dates—August 19th, 20th, 25th, 28th, etc.—each claimed as confirmed, but these are estimates from different sources. Confirmed schedules only appear in Korail announcements, so don't rely on any dates before that.

Where to check:

• Korail+ app and integrated website (www.korail.com) announcements — Your top priority. Trains operating from September 1 onward went on sale August 5 at 10:00 through these two channels (the old Korail Talk version and SRT app may not support integrated train booking, or only non-member booking), and Chuseok allocation announcements will appear here. To confirm whether station counter purchases are available, call ☎1544-7788. (Needs official confirmation)
• In the same announcement, check one line to see whether Chuseok special transport period allocation is already included in the opened integrated booking, or split off into separate holiday advance reservation. Just because integrated booking opened doesn't mean holiday allocation is already released.
• SR announcements (etk.srail.kr) — After September 1 integration, Korail channels are the baseline for Chuseok allocation announcements. Check SR announcements only for reference.
• Phone inquiries: Korail Customer Center ☎1544-7788, SR Customer Center ☎1800-1472 — When announcements are confusing, calling is fastest.

How Can Foreigners Participate in Advance Reservation?

Advance reservation is members-only, so registration comes first, but foreigners' chances vary significantly by situation. Before starting preparation, check which category you fall into:

Items required for registration and verification vary by member type and timing. The preparation steps below are for those in the first and third categories.

1. Check which account type you have first (2026 top priority). All Chuseok trains operate from September 1 onward, so you'll book with an integrated member account. If you were only registered with Korail, it's automatic conversion—nothing to do. If you were only registered with SR (SRT), or registered with both Korail and SR, you need to complete the conversion process, and do this before booking day. The conversion website opened mid-July and has been in full operation since Korail+ launch on August 3.
   • Where: Log into Korail+ app or www.korail.com and you'll be directed to the integrated member conversion page. The SRT app and SR homepage can also enter this same page, and both PC and mobile work.
   • What it does: It's not re-registration but an account consolidation process. Korail-only registration → automatic conversion (nothing to do). Both registrations → account automatically converts, but to transfer SRT usage history and discount coupons to the new account, you need to complete a consent process on the conversion website. SR-only registration → within the conversion website, you proceed with Korail member registration and SR usage history/benefit transfer consecutively (no need to separately register in the app).
   • What to prepare: Existing ID and password, contact info for verification (Korean mobile number), and for foreigners, passport number or alien registration number. (Items required by type need official confirmation)
   • If traveling as a group, have each companion complete this step too, since per-person ticket limits apply.
2. Try registration and verification at least 1-2 weeks early. If you try to register on booking day morning and get blocked at verification, that year's advance reservation is over for you. Foreigners especially hit walls at this stage, so testing early and preparing alternatives if it doesn't work is safer. Problems foreigners face with Korail app registration/verification, and alternatives within the official process, are detailed in the Korail App Foreigner Problems Guide.
3. Test your payment method for real before booking day. Korail's English site (korail.com/global/eng) supports overseas-issued cards (VISA, Mastercard, JCB). It's the same www.korail.com domain, but the Korean integrated screen and English booking screen have different paths, so payment support differs. However, on Korean screens and holiday-specific booking screens, many reviews report overseas card rejections (as of 2026-08). So test this way — On the actual channel you'll use for booking (Korail+ app or Korean screen at www.korail.com), book one short-distance Mugunghwa-ho ticket for a nearby date, complete payment, confirm it goes through, then cancel before departure. ⚠️ Cancellation fees may apply depending on timing, so test with a ticket that has plenty of time before departure and cancel immediately (fees by section detailed in KTX Seat Classes & Refund Policy). If rejected, definitely prepare backup payment methods like Korean-issued cards or simple payment. The full flow for booking KTX without a Korean card is in Booking KTX Without Korean Card or Verification.
4. On booking day, connect before the start time. Holiday booking pages get swamped with connection queues. Holiday booking has both start and end times — for 2026 Seollal it was general booking 07:00~13:00, priority booking 09:00~15:00. After that window, the holiday booking page itself closes, so check that year's times in announcements and log in early. Prioritize PC web (www.korail.com) with the app as backup. Bigger screen shows seat status at a glance, and if Korean screens overwhelm you, you can turn on browser translation. Browser translation doesn't work in apps, so if going app-only, enable phone screen translation (Google Lens, etc.) beforehand. Some screens require selecting departure/arrival stations in Korean, so copy frequently used stations in advance for convenience — Seoul (서울), Yongsan (용산), Daejeon (대전), Dongdaegu (동대구), Busan (부산), Gwangju Songjeong (광주송정).
5. Once you get your outbound ticket, book the return right there in the same session. Completing round-trip in one connection is safest. The return ticket is actually harder — outbound to provinces spreads departures over several days, but return to Seoul at the end of the holiday all concentrates at once. The most common booking failure is securing the outbound ticket, relaxing, then failing to get a return ticket. With round-trip ticket limits, if your group is large, don't pile all round-trip bookings on one person.
6. Check the payment deadline and set an alarm. Holiday bookings give a separate multi-day payment period starting the day after the booking schedule ends, and seats auto-cancel if unpaid within that window (period set in each year's announcement — needs official confirmation). The booking confirmation screen and announcement will display the payment deadline, so screenshot it and set your phone alarm for 2 hours before the deadline. This deadline time gets reused for cancellation hunting below.

It Sold Out — 5 Ways to Still Get Tickets

Missing advance reservation or seeing sold-out doesn't mean it's over. Holiday tickets keep moving even after sold-out.

1) Cancellation Refreshing — Timing Is Everything

• Right after advance reservation payment deadline: That exact deadline you set an alarm for. Unpaid tickets auto-cancel in batches, releasing seats all at once. This is the first golden window.
• Night before departure, morning of departure, right before departure: Times when people whose plans changed release tickets before penalties grow larger. Especially right before cancellation fees jump 1-2 days before departure. Fees by section are detailed in KTX Seat Classes & Refund Policy.
• The basics: keep your desired route displayed in the app and refresh repeatedly. Sometimes a waitlist function (auto-assigns if seats open) appears for sold-out trains, but it may not be offered during major holiday transport periods. (Needs official confirmation)

2) Standing Tickets — Stand and Save 15%

Even when all seats sell out, standing tickets are sold on some trains. Standing tickets discount 15% from standard class fare (as of 2026-08). However, you can only buy when "standing available" displays in search results; if it just says "sold out," standing isn't available either. Standing displays sometimes appear close to departure, so don't give up—check again.

Even if standing doesn't show in the app, that's not the end. Standing tickets for sold-out trains often aren't released online and are only available at station counters or in-station kiosks. If you go to the station and ask in person, the result can be different, so don't give up based on online searches alone (see 5) Station Counters & Kiosks below). Seoul→Busan on KTX is about 2 hours 40 minutes, so if you must go, standing is bearable.

3) Seat+Standing Combo — Sitting for Half the Journey

Sometimes seats remain for only partial segments even when full-journey seats are sold out. In these cases, you can buy a seat+standing combo ticket (e.g., Seoul→Daejeon standing + Daejeon→Busan seated). This is much less tiring than full-journey standing and is a classic Plan B during sold-out seasons. How to actually buy:

• Tap a train in search results. Even if the list shows "sold out," selecting the train and entering the seat-type selection screen may display combo ticket options. You'll miss it if you only look at the list.
• If it doesn't show, split it yourself. If Seoul→Busan doesn't work, search Seoul→Daejeon and Daejeon→Busan separately and buy two tickets. As long as the train numbers match, you can stay on the same train without transferring.
• After boarding is important. When the seated segment begins (Daejeon in the example above), you need to move to your assigned seat car. Move when arrival announcements start. If you have a lot of luggage, holiday aisles get packed and moving becomes quite cumbersome, so if you have large suitcases, it might be better to just stand in place until the seated segment.
• Trying to board partway and ride beyond your ticket is no longer as safe a card as before. The October 1, 2025 terms revision means "in-train section extension" beyond the ticketed segment is treated identically to riding ticketless (no ticket possession), regardless of voluntary declaration. The additional fare also rose from 0.5x to 1x the base fare — Seoul~Busan would cost fare 59,800 KRW + additional 59,800 KRW = 119,600 KRW. If you avoid or refuse the conductor's ticket check, it rises to 2x (total 3x). So the rule is to buy standing tickets for remaining segments in advance, and if you must extend in-train, tell the conductor first — only when reasons are recognized (sudden schedule change, health issue) can limited extension ticketing be issued, with additional fare waived. (Application method may vary by train and situation — needs official confirmation)

4) Change Train Class — ITX-Saemaul, Mugunghwa-ho

Don't insist on KTX only. Regular trains like ITX-Saemaul and Mugunghwa-ho often have remaining seats. They do take considerably longer, though — Seoul→Busan on KTX is about 2 hours 40 minutes, but Mugunghwa-ho takes over 5 hours. Fares are proportionally cheaper, so think of it as "trading time to sit."

5) When Online Keeps Failing — Station Counters & Kiosks

This is the most realistic exit for those repeatedly blocked at app registration/verification or overseas card payment. "Online-only" applies only during the advance reservation period. After advance reservation ends, remaining seats transition to regular sale available at Korail+ app, website, station counters, and in-station kiosks (self-ticketing machines), and standing tickets for sold-out trains can also be purchased at counters and kiosks.

• For station counter operating hours during holidays or special holiday counter operations, ask ahead by calling ☎1544-7788.
• Tips for in-person ticketing—bringing passport, English service at major stations, showing written notes—are in Booking KTX Without Korean Card or Verification.

When Trains Don't Work — Express Bus, Intercity Bus, Flights

• Express bus: The #1 train alternative. More frequent runs than trains, with temporary additions during holidays, so relatively higher chances of getting seats. Highways like Gyeongbu have bus-only lanes, so buses move faster than cars even in holiday traffic. Importantly, bus bookings also open early—holiday express bus reservations have traditionally opened about a month before the special transport period (2025 Chuseok opened Sept 3 at 10:00, special transport 10/2~12). Timing is similar to train advance reservations, so when train booking dates are announced, check bus opening dates that same week. Opening dates and times vary by year's channel announcements. Booking channels are KOBUS (www.kobus.co.kr), BUSTAGO (bustago.or.kr), and Tmoney GO app. How foreigners book express buses in English is detailed in Korea Express Bus Booking in English.
• Intercity bus: Connects to smaller cities not served by express buses. Different terminals and routes, so if your destination is a smaller city, check intercity bus routes first. How to find terminals and buy tickets is in Korea Intercity Bus Terminal Guide.
• Domestic flights: Routes like Gimpo→Gimhae (Busan) and Jeju sometimes have seats remaining even during holidays. Fares are more expensive than usual, but decent if you're trading money for time.
• Rental car or private car: Holiday highways often take 2-3x normal travel time. With international driver's license requirements, not recommended for first-timers.

If You Can't Get Tickets — Staying in Seoul Is Also a Good Answer

Not traveling at all is also a perfectly good choice. During holiday weekends, the four major palaces (Gyeongbokgung, Changdeokgung, Changgyeonggung, Deoksugung) plus Jongmyo Shrine and Joseon royal tombs have traditionally been open for free (separately reserved/paid areas like Changdeokgung Secret Garden are often excluded. Opening periods and scope confirmed in that year's Korea Heritage Service announcement — needs official confirmation). Even Jongmyo, which normally requires reservations, has had days of free admission.

Plus Seoul empties out during holidays. A significant portion of the population leaves for provincial areas, creating a spaciousness hard to imagine at normal times. However, many shops close on the first day of the holiday and the actual holiday day, and commercial areas usually return to normal from the second day onward. Stock up on food and necessities for the first day in advance, plan one day for palaces and one for city areas during the holiday, and you can spend the holiday without travel stress.

Holiday Travel: Times to Avoid and Times to Target

September 2026 Has East Asia Moving Simultaneously

September 2026 isn't just Korea moving. September 19~23 is Japan's 5-day Silver Week (Respect for the Aged Day 9/21 and Autumn Equinox 9/23 create a consecutive holiday), immediately followed by Korea's Chuseok September 24~27, and Korea's Chuseok day itself, September 25, coincides with the Mid-Autumn Festival in Chinese-speaking regions (China 9/25~27, Taiwan 9/25, Hong Kong 9/26).

In other words, the nine days from September 19 to 27 layer visitors from Japan, China, Taiwan, and Hong Kong directly onto Koreans' mass migration. Not just train tickets but accommodation, airport rail, and airport limousines can't be judged by normal standards. If you're planning to travel in Korea during this period, lock down transportation and lodging all on the same day.

Which Direction Are You Traveling?

Korean holiday travel is a one-way flow: "Seoul → provinces" first, "provinces → Seoul" later. Difficulty totally differs depending on whether you're moving with that flow or against it.

• Living in Seoul or arriving in Seoul and heading to provinces (outbound to provinces): Same direction as Korean flow, so hardest. Peak is typically the afternoon before the holiday ~ morning of the first day — for 2026, that's September 23 (Wed) afternoon ~ 24 (Thu).
• Living in provinces and coming to Seoul (Seoul-bound/reverse direction): Provinces → Seoul direction at the start of the holiday is opposite Korean flow, so seats often remain even without advance reservation. If you're planning to come to Seoul, actually check searches now and you might surprisingly get something. For foreign workers living in provincial cities, this is one of the few pieces of good news during holidays.
• Returning to Seoul at the end of the holiday (Seoul-bound peak): Peaks from the afternoon of the holiday day itself through the next day. For 2026, September 25 (Fri) afternoon ~ 27 (Sun) will likely stay crowded continuously. Tickets for this direction sell out first. If you can't get them, don't linger—book express buses or domestic flights in parallel, and for trains, target late-night time slots on the last day of the holiday.

Relatively quiet windows are early morning on the actual holiday day (when everyone's performing ancestral rites) and late night on the last day of the holiday.

If you targeted late-night time slots, plan your route after arrival too. During holiday weekends, Seoul subway and city buses have traditionally extended operations until 1-2 AM (extension scope confirmed in that year's Seoul city announcement — needs official confirmation), but if you arrive after those hours, taxis are all that's left. How late-night fares work is in Taxi Fares & Night Surcharge, calling taxis without a Korean number in Calling Taxis Without Korean Phone, and if waiting for first train see Seoul Subway Complete Guide.

Whichever time slot you choose, stations and terminals are much more crowded than usual. Arrive 20-30 minutes earlier than departure time. Finding a seat in Seoul Station or Busan Station waiting rooms during holidays is difficult.

Transportation & Payment Connection Tips

The core of holiday ticket hunting is ultimately speed. Cancellation tickets vanish in seconds, and if KTX doesn't work, you need to immediately switch to express buses right there. But opening separate train and bus apps, logging in separately, and paying separately—those few seconds just disappear.

So foreign traveler communities repeatedly see stories every holiday of "got blocked at Korail registration/payment, eventually detoured through overseas booking sites." LACHA is an app designed precisely for that point. Built to work without identity verification, usable with just passport and overseas card without Korean phone number or Korean account, and accepts foreign payment methods like Alipay. Especially, you can search and book both KTX and express buses in one app, so when trains sell out, you can check bus seats in the same screen flow and switch to Plan B.

But let me be honest. Holiday advance reservation allocations themselves only sell through Korail-exclusive channels. So a realistic combination is: advance reservation through Korail, then remaining seats/cancellations/express buses/taxis through LACHA.

Want to search and book KTX and express buses in one app? Check out LACHA.

Built to work without a Korean phone number or bank account, with overseas payment methods like Alipay, WeChat Pay, and Apple Pay. Taxi hailing plus KTX, express bus, and airport railroad (AREX) booking — all in one app.

Frequently Asked Questions (FAQ)

Q1. Do holiday tickets check ID (passport) when boarding? Normally KTX and Mugunghwa-ho don't verify ID beyond showing the ticket. However, if you used discount tickets or passes (senior/disability discounts, Korail Pass, etc.), conductors may request eligibility verification, so carrying your passport is safer. Having a passport also makes things much faster when buying tickets at station counters. (Application scope needs official confirmation)

Q2. Is there a separate "foreigner booking opening day"? If I miss advance reservation, can I not ride trains that holiday? What English sources commonly call "foreigner booking opening day" (when can foreigners book) isn't a separate system—it usually refers to the exact moment general sales open after member-only advance reservation ends. Remaining seats not sold in advance reservation and unpaid auto-canceled seats release back to general sales at this time, and they become available not only via app and website but also at station counters and kiosks. So channels that open late like English channels or general sales make it hard to catch popular routes like Seoul–Busan—popular time slots are often already gone by then. But you don't need to give up—after that, cancellation tickets keep appearing the night before departure, morning of departure, and right before departure. Many people give up when they see sold-out screens, so those who keep refreshing ultimately get tickets.

Q3. What happens to SRT now? From September 1, SRT changes its name to KTX-Sancheon and is searchable and bookable together with KTX in the Korail+ app. All of Chuseok 2026 (9/24~27) falls after the merger, so the old structure where "Korail and SR each announced their own booking dates, giving you two shots" is gone. What still works is searching both departure stations. Departures from Seoul Station/Yongsan Station and departures from Suseo Station run different routes and time slots. The Suseo axis has relatively fewer runs, so popular times go faster there — if Seoul Station is sold out, check Suseo right away, and vice versa. The differences between the two services are covered in SRT vs KTX.

Q4. Do KTX fares go up during the holidays? There's no holiday surcharge as such. If anything, the September 2026 merger drops base fares by an average of 10% (Seoul~Busan 59,800 KRW → 54,400 KRW). But what you actually pay tends to rise during holidays. During the special holiday transport period, free-seating cars and family (infant-accompanying) seats don't run, and discount products like the N Card along with various special fares have traditionally been suspended. In effect, the cheap options disappear all at once. Standing tickets, on the other hand, still get the 15% discount off standard class fare even during holidays (as of 2026-08). The list of discounts suspended that year appears in the booking announcement, so give it a scan.

Q5. Can I board with large luggage on a standing ticket? You can, but be prepared. Standing passengers ride in the gangways between cars or by the doors, and during holidays even that space fills up with people. If you have a large suitcase, it's easier to put it on the luggage rack beside the car doors first and move yourself separately. If your bags are big and the trip is long, an express bus with a luggage compartment may be a much better choice than standing on a train.
