Tips for 25 min Connections
Check whether your connection is within the same terminal or requires the T1-T2 shuttle train, as this changes your buffer needs significantly.
Korean Air and Delta/SkyTeam partners mostly use T2, while most other international carriers use T1, so allow extra time if switching alliances.
Transfer desks on the arrival level in both terminals can quickly rebook or reissue boarding passes if you're tight on time.
Duty-free and lounges are extensive in both terminals, so a longer layover here is genuinely pleasant rather than just functional.
If arriving internationally and connecting to a domestic Korean flight, budget extra time since domestic check-in is in a separate area.

High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
A free inter-terminal shuttle train connects T1 and T2 in about 15-18 minutes of ride time, running every 5-10 minutes, with additional walking and processing time bringing total transfer time to 25-35 minutes. Passengers connecting within the same terminal move through dedicated transfer corridors without needing to re-clear immigration, though a secondary security screening point exists at the transfer level for international-to-international passengers.
