01 1. [Key Takeaways] Seoul to Busan Transit Speed, Price & Comfort Comparison

The fastest and most convenient method to travel from downtown Seoul to Busan is via the KTX (Korea Train Express) bullet train from Seoul Station to Busan Station, taking exactly 2 hours and 15 minutes at speeds up to 305 km/h, priced at ₩59,800 KRW (Standard Class).

While domestic flights from Gimpo (GMP) to Busan Gimhae (PUS) take only 55 minutes in the air, when factoring in airport check-in security (45 minutes) and subway/taxi transit from downtown Seoul and Gimhae Airport into Haeundae, total city-center to city-center travel time is approximately 3.5 to 4 hours, making the direct KTX bullet train significantly more time-efficient.
