Domestic-to-Domestic Connections at O'Hare

That said, if your incoming flight lands at an outlying gate in Concourse L or K, walking to a departure gate in Terminal 1 can take up to 15 minutes of brisk walking. Add a slight delay to your first flight, and that one-hour cushion shrinks fast.

International arrivals change the math completely because every passenger must clear Customs and Border Protection (CBP), collect checked luggage, clear security screening again, and often transfer from Terminal 5 to Terminals 1, 2, or 3.

This entire multi-step process demands a minimum of two hours, though three hours is much safer during peak afternoon arrival banks. how long layover chicago international flight is a vital consideration for smooth global travel.
