Complete Guide to Airport Timing
O'Hare International Airport (ORD) is one of the world's busiest airports and Chicago's primary international gateway. With 4 terminals and notorious Chicago traffic, proper timing is essential.
How Early Should I Arrive at ORD for a Domestic Flight?
Arrive 2 hours before departure for domestic flights. ORD's sprawling layout means you'll need time for parking, navigating to your terminal, clearing security, and taking the Airport Transit System (ATS) train to your gate. During peak hours, arrive even earlier.
How Early Should I Arrive at ORD for an International Flight?
Arrive 3 hours before departure for international flights. Terminal 5 handles all international departures and can be especially busy. International check-in and security procedures require additional time, and Terminal 5 is furthest from some parking areas.
When is ORD Most Busy?
ORD's busiest hours are 5am-8am and 4pm-7pm. Plan accordingly or fly during off-peak hours when possible.
How Much Time Should I Allow for Chicago Traffic to ORD?
Traffic on the Kennedy Expressway (I-90) and I-294 can add 45-90 minutes during rush hour. From downtown Chicago, budget at least 60 minutes during peak times. Winter weather can add additional delays. Use our calculator above for real-time traffic estimates.
Which ORD Terminal Should I Go To?
ORD has 4 terminals: Terminal 1 and 2 (United), Terminal 3 (American, Delta, others), and Terminal 5 (all international flights). Check your airline's terminal before leaving. The Airport Transit System (ATS) train connects all terminals—allow 10-15 minutes for transfers between terminals.

Arrive 2 hours before your domestic flight departure.
