O'Hare Airport Info to make traveling easier

Chicago's O'Hare Airport reclaimed the title of busiest airport for takeoffs and landings in 2014, but not for number of people. Some basic O'Hare Airport info may make your travelling easier.

Popular Travel Times:

  • Busiest days to travel: Mondays, Thursdays and Fridays. Fly early, but not too early.
  • Busiest times are 6-8 am, and 3-5 pm.
  • Worst time for delayed flights: 7-9 pm, due to ripples from the 3-5 pm rush.

Security Tips and Checkpoint Wait Times

  • TSA screening times vary, depending on which terminal you’re departing from. Always allow at least 20 minutes for security, but you can do a same-day check of screening line times at:
  • Only the Terminal 5 TSA checkpoint is open 24 hours. Terminal 1, 2 and 3 checkpoints are open approximately 4 am -11 pm.
  • Make TSA screening easier on everyone:
    • Have your boarding pass and ID in hand when you get to the front of the line.
    • Wear slip off shoes and a light coat, weather permitting.
    • Liquids must be less than 3.4 ounces, bottles must fit in 1 quart bags, and be placed in a bin for screening. Carry an empty water bottle and fill it at a drinking fountain once you’re past security.
    • Have laptops and large tech items easily accessible
    • Use TSA Pre-Check ( for a fast and easy screening process (short lines, no shoe removal, no liquid checks, no computer removals)

International Travel:

  • See your airline’s rules for check-in times, but in general, allow a minimum of 3 hours before your flight for check-in, baggage check, and security. Don’t forget your passport.

Regional Travel:

  • Something to consider if you’re connecting through O’Hare: Short hop flights get delayed or canceled first, because priority is given to larger, long haul flights. Instead of taking a regional flight from eastern Iowa, southern Wisconsin, southern Illinois or Indiana, drive and park at PreFlight Airport Parking.


Free WiFi is available in all ORD terminals for a limited amount of time. If you need to work off stress from a delayed flight, there’s a Yoga Room in Terminal 3.
