Can I make a 1 hour 45 min connection at ICN on an international flight?
1 hour 45 min clears the 60-minute international minimum connection time at Incheon International, but you should still head directly to your gate. 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.
How much time do I need for a layover at ICN?
We recommend at least 1 hour for a comfortable connection at Incheon International. This gives you enough buffer for security (typically 15 minutes) and transit between terminals (up to 35 minutes).
What happens if I miss my connection at ICN?
Both terminals have SkyTeam and Star Alliance transfer/rebooking desks near arrival gates that can quickly reissue boarding passes or rebook missed connections, and Korean Air in particular is efficient at handling misconnects at its T2 hub.
