From real experience
KTX train ticket prices in South Korea fluctuate significantly.
Booking in advance and monitoring prices across platforms like Trip.com and NOL can yield better deals. For example, round-trip tickets for September might cost around 38,000 KRW, whereas summer travel or last-minute bookings can be much higher (e.g., 60,000-70,000 KRW one-way). Be cautious with some third-party sellers like Biletix, as reports of issues with refunds and overbooking exist.
