ORD TSA wait times at Chicago O'Hare International

Live checkpoint data is temporarily unavailable for ORD, so the current number is a planning estimate and the airport-specific notes below matter more than usual.

The official FlyChicago map is the strongest source for matching your terminal and gate area to the correct checkpoint.

Terminals 1, 2, and 3 handle most domestic traffic, while Terminal 5 is the major international workflow.

ORD's official TSA page publishes reference hours, but those hours can change with airport operations and may conflict with a live feed row. Arrival Mode does not infer open or closed from a missing reading.

Terminal 1 is the major United terminal and has its own security entry points shown on the official ORD map.

Terminal 2 carries a smaller domestic mix and should be checked separately from Terminal 1 even when your airline is connected to United.

Terminal 3 is the main American Airlines terminal and should be treated as its own security decision.

Terminal 5 handles many international departures and has a separate screening environment from the domestic terminals.

Use the official map for the gate-side walking plan because checkpoint choice and post-security connectivity can vary by terminal and concourse.

United drives the biggest volume in Terminal 1, while American dominates Terminal 3, so those two terminals shape most same-day congestion.

Terminal 5 handles the international-carrier workflow, while Terminal 2 carries a smaller mix including Delta, Alaska, Spirit, and Air Canada.

ORD travelers should confirm the exact departure terminal before choosing security because Terminals 1, 2, 3, and 5 each run their own checkpoint workflow.

If you are flying international out of Terminal 5, treat that as its own security workflow rather than an extension of the domestic-terminal experience.

ORD publishes checkpoint reference hours and a separate live wait feed. Use the terminal map, current reading, and airline app together before leaving.
