KTX, flight or bus?
For most first-time visitors, the best choice is the one that protects door-to-door time rather than the one with the shortest published travel time.
Quick answer
KTX is usually the simplest city-center-to-city-center option. A flight can make sense when it fits an airport connection or your wider itinerary. The bus can be useful when price matters more than travel time.
Strong for travelers staying near rail-friendly areas and for those who want to avoid airport security, check-in and airport transfers.
Consider it when your trip already passes through an airport, or when a flight connects naturally with Jeju or another domestic segment.
Useful for budget-focused travel, but compare terminal access and the longer usable-time cost.
