AD PLACEMENT — CONTEXTUAL
Budget extra time to walk or shuttle between the separate domestic and international terminals — they are not internally connected airside.
There is no international transit lounge, so any international-to-international connection means clearing Korean immigration and customs and then re-entering security.
Air Busan operates the most connection-friendly schedules here as the airport's home carrier, so its own transfers tend to be smoother.
Signage is in Korean and English but the terminal layout is simple enough that a rushed connection is manageable if the transit time is respected.
Peak morning and early evening banks can bunch up security lines in the international terminal, so don't cut connections too close during those windows.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
The Domestic and International Terminals are physically separate buildings a few hundred meters apart, linked by a covered outdoor walkway and a free shuttle bus that runs every few minutes. Any connection touching international flights requires full immigration and customs processing since there is no sterile international transit corridor, and domestic-to-domestic transfers still require re-entering security in the other terminal.
