KTX Classes Explained
KTX trains operated by KORAIL generally offer two reserved seating classes: Standard Class and First Class. Standard Class is the main KTX option, with assigned seats in high-speed carriages for long-distance travel across South Korea. First Class provides wider seating, more personal space, and a quieter layout on most mainline KTX departures. The exact carriage layout can differ between KTX trainsets, including KTX-I and newer KTX-Sancheon formations. Availability of First Class should be checked for the selected departure. To compare current seat options, use the search inputs at the top of the page.

Key KTX routes in South Korea
The busiest KTX corridor is Seoul to Busan on the Gyeongbu high-speed line, serving major stations such as Daejeon, Dongdaegu, and Busan. Seoul to Daejeon and Seoul to Dongdaegu are common shorter high-speed trips on the same axis. On the Honam corridor, KTX trains link Seoul or Yongsan with Gwangju-Songjeong and Mokpo, serving southwestern South Korea. Other KORAIL KTX services connect Seoul with regional destinations depending on the timetable period. Travel time, stopping pattern, trainset type, and First Class availability can differ by departure, so check the exact KTX schedule for the selected date.
