Checkpoint operations can change. Review O'Hare's official TSA information and your airline's guidance before leaving for the airport.
Published checkpoint hours
The airport states that checkpoint hours are general operating hours and may be affected by day-to-day activity. The following is a planning reference, not a guarantee:
| Terminal | Checkpoint hours listed by O'Hare | Notes |
|---|---|---|
| 1 | CP1: 3:30 a.m.–11 p.m.; CP2: 4 a.m.–8:30 p.m.; CP3: 3:45 a.m.–8 p.m. | PreCheck hours differ by checkpoint. |
| 2 | CP5: 3:15 a.m.–11 p.m. | PreCheck listed 3:30 a.m.–8 p.m. |
| 3 | CP6, CP7, CP7A and CP8 have different hours. | Check the official table for the specific checkpoint. |
| 5 | CP10: 24 hours | PreCheck listed 3:45 a.m.–8:30 p.m. |
Build a reliable security plan
- Confirm your departure terminal and airline's recommended arrival time.
- Check the current checkpoint table, especially for early or late departures.
- Allow time for the parking or ground-transportation transfer before security.
- Pack according to the current TSA rules and keep identification and boarding pass accessible.
- Use the airline's app for flight changes and gate updates.
TSA PreCheck and identification
TSA PreCheck can offer an expedited screening experience at participating checkpoints, but availability is not guaranteed at every time. Travelers should also ensure they have acceptable identification; O'Hare publishes current information about TSA ConfirmID and REAL ID requirements.

Terminal 5 checkpoint 10 is listed as open 24 hours. Other checkpoint hours vary by terminal and may change because of airport activity, so confirm the official schedule before travel.
How early should I arrive for my flight?
Follow your airline’s arrival recommendation and add time for parking, baggage drop, mobility needs, and security. Allow additional time during holidays or when traveling from an economy lot.
