How to Book KTX Train Tickets in Korea: KORAIL Pass Guide for Foreigners [2026]
Planning to travel beyond Seoul to major South Korean cities like Busan, Gyeongju, Jeonju, or Gangneung? The KTX (Korea Train eXpress) high-speed rail is by far the fastest, cleanest, and most convenient way to explore the country.
However, many international travelers get confused about whether to buy individual KTX tickets or a KORAIL Pass(KR Pass), and often run into foreign credit card payment errors. Here is a complete guide to booking KTX tickets smoothly and maximizing your train travel savings!
🚄 1. KORAIL Pass vs Individual KTX Tickets: Which Saves Money?
The KORAIL Pass is an exclusive rail pass for foreign tourists that allows unlimited rides on KTX and standard Korail trains for a set period. But does it actually save you money?
| Pass Type | Adult Price (13+) | Child Price (6–12) | Usage Condition |
|---|---|---|---|
| 2-Day Select Pass | 131,000 KRW | 66,000 KRW | Choose any 2 days within 10 days |
| 3-Day Consecutive Pass | 186,000 KRW | 93,000 KRW | 3 consecutive days |
| 4-Day Select Pass | 234,000 KRW | 117,000 KRW | Choose any 4 days within 10 days |
| 5-Day Consecutive Pass | 275,000 KRW | 138,000 KRW | 5 consecutive days |
💡 Easy Rule of Thumb:
• Seoul ⇄ Busan Round-Trip Only(~120,000 KRW): Do NOT buy a pass! Individual tickets are cheaper.
• Multi-City Itinerary(e.g., Seoul → Gyeongju → Busan → Jeonju → Seoul): BUY THE KORAIL PASS! You will save a substantial amount.

If you are taking only one or two train rides, booking individual tickets 1 month in advance is recommended.
Step 1: Use Official Foreign Korail Website
Visit the official Korail English website(letskorail.com). Do NOT use unauthorized third-party sites charging heavy markup fees!
🚇 Visit "official Korail website"Step 2: Select Route & Seats
Choose your departure station(e.g., Seoul or Yongsan), arrival station, date, and passenger count. You can select your preferred seat direction and wagon.
Step 3: Solving Foreign Credit Card Errors
🚨 FOREIGN CARD PAYMENT TIP:
If your overseas Visa/Mastercard is rejected on the official Korail app, book your individual KTX tickets via trusted global booking OTAs like Trip.com or Klook, which accept all international credit cards, Apple Pay, and PayPal without authentication errors!
📝 3. How to Use & Reserve Seats with KORAIL Pass
- Purchase the Pass: Buy your KORAIL Pass online via the Korail website or global platforms(Klook/KKday).
- Reserve Seats in Advance: Having a pass alone does NOT guarantee a seat! You must reserve your seat numbers on the Korail website under "My Ticket" -> "KORAIL PASS"(up to 2 seat reservations per day per person are allowed for free).
- Boarding: Korean train stations do not have ticket turnstile gates! Simply walk directly onto the platform. Keep your e-ticket/pass and Passport on your phone in case a conductor checks.
🚨 4. Important Exclusions You MUST Know
- SRT Trains NOT Covered: SRT high-speed trains departing from Suseo Station in southern Seoul are operated by a separate company and are NOT valid with KORAIL Pass!
- Subways & Airport Express NOT Covered: KORAIL Pass cannot be used on Seoul Subways, AREX Express, or city buses. Use your T-money or WOWPASS for local transit!
- Luggage Space: KTX trains have luggage racks at the end of each car. Bring large suitcases early to secure a shelf space!
Book your KTX tickets 1 month ahead, grab your KORAIL Pass for multi-city journeys, and explore all of South Korea by train!
