How to book KTX tickets
Use the correct station and official sales channel before paying.
Travel passes save some visitors a lot of money — and quietly cost others more than individual tickets. We compare every legal combination for your exact itinerary and show the arithmetic, so you can decide in seconds.
Enter your train journeys and see whether a Select or Consecutive rail pass beats individual KTX tickets — including which dates to use it on.
Check my train planCompare current 1-, 2-, 3-, 5- and 7-day transit passes against pay-as-you-go fares, including the physical card and excluded rides.
Check my Seoul transit planBuild a trip and optimize the verified calculators enabled for this deployment, with a baseline-vs-optimized cost comparison.
Plan my whole tripCompare complete verified ticket totals between Seoul Station and Incheon Airport T1 or T2. Missing child, senior, last-mile or journey-time values are never guessed.
Compare airport costsNo AI guesswork and no sponsored ranking. We enumerate every valid pass/date combination, price each one from a versioned database of verified fares, and pick the cheapest — with a clearly-labeled "recommended" option when a slightly pricier choice is meaningfully more convenient. Commissions can never change the ranking; that separation is enforced by automated tests. Read the full methodology and see our data sources.
