KTX Train Guide: how it works in South Korea — first-hand
Short answer
Book KTX tickets 1-2 weeks in advance via platforms like Trip.com to ensure availability and potentially lower prices. If tickets appear sold out, you can purchase standing tickets at station counters and occupy empty seats until the ticketed passenger arrives.
From real experience
KTX train tickets can be booked in advance through platforms like Trip.com, which may offer lower prices and accept international payment methods like MIR cards, unlike the official Korail website which may require a Korean or foreign card.
Boarding KTX trains typically does not involve baggage checks at the station. Luggage can be stored in overhead compartments or designated racks in the carriage. Seat checks are conducted periodically by staff.
