Incheon Airport Layover: What to Do in 5, 8 or 12 Hours
For an Incheon Airport layover, use one rule: under 7 hours, stay airside; 7 to 8 hours is marginal; with 8 hours or more, you can ride into Seoul and back. If you have less, stay airside: Incheon International Airport (인천국제공항, Korea’s main international gateway) has showers, nap zones, a capsule hotel and free culture corners, which beat spending your whole layover in a train and an immigration line.
