If you're traveling between Seoul and Busan, you have two realistic options: the KTX high-speed train or a domestic flight. On paper, flying looks faster. In real life, the train often wins.
Quick answer
For most travelers, the KTX train is faster door-to-door, simpler, and more comfortable.
Train vs Flight (simple comparison)
| Factor | KTX Train | Flight |

| Travel time | ~2h 30m onboard | ~1h flight |
| Door-to-door time | ~3 hours total (central to central) | ~3.5–4 hours total |
| Departure location | Seoul Station (city center) | Gimpo Airport (requires airport transfer) |

| Luggage | Flexible; no strict liquid limits | Airline baggage rules apply |
| Scenery | Yes (countryside views) | No |
Why the train often feels faster
Flights look faster because the air time is short. But you must arrive early at the airport, pass security, wait for boarding, and then travel from the airport into Busan city.
The KTX departs from central Seoul and arrives at Busan Station, which is already near major hotels and subway lines.

FAQ
Isn’t flying faster than the train?
The flight time is about 1 hour, but once you add airport arrival time, security, and transfers to/from airports, the total door-to-door time is usually similar—or longer—than taking the train.
Which is cheaper?
Prices can be similar. Flights sometimes run promotions, but airport transfers and baggage fees can increase total cost. KTX pricing is generally stable and predictable.
What do most tourists choose?
Most international visitors choose the train because it departs from central Seoul and arrives in central Busan with minimal hassle.
