How to read the numbers

Times are station-to-station or gate-to-gate. Door-to-door adds subway, security, and traffic. Holiday weeks (Seollal, Chuseok) inflate bus and KTX prices first.

Pitfalls

Holiday blackout. Seollal and Chuseok sell out — buy KTX early or lock a bus seat.
Station names. Busan Sasang vs Nopo, Singyeongju vs Gyeongju downtown — plan the last mile.
Luggage. KTX has racks; AREX Express has dedicated space; city buses hate giant suitcases at rush hour.

FAQ

Is KTX always faster than flying Seoul–Busan?
Door-to-door, yes for most travelers. Flights need airport transfers on both ends; KTX drops you into the city fabric.
Can I use T-money on KTX?
No. KTX is ticketed separately. T-money covers subway, city bus, and many taxis.
