Do I have to go through security again for connecting flight o hare?

Navigating Security for Connecting Flights at O'Hare International Airport

Passengers connecting through O'Hare International Airport are required to undergo TSA security screening, regardless of their terminal. This measure ensures the safety of all travelers and complies with federal regulations.

Security Screening Process

To expedite the security screening process, consider the following tips:

• Arrive at the airport with ample time for check-in and security screening.
• Place all liquids, gels, and aerosols in a clear plastic quart-sized bag.
• Remove all electronic devices larger than a cell phone from your carry-on luggage.
• Wear comfortable clothing and shoes that can be easily removed.

Terminal Transfers

For connections within Terminals 1, 2, or 3, passengers can take advantage of the free Airport Transit System (ATS). This automated people mover circulates throughout the terminals and provides a convenient and efficient way to transfer between flights.

Exception for Same-Day Domestic Connections

In certain cases, passengers connecting to a same-day domestic flight within Terminal 1, 2, or 3 may be able to bypass the security screening process at O'Hare. To qualify, passengers must meet the following criteria:

• Have a boarding pass for both flights.
• Not have checked luggage.
• Not have had contact with anyone outside the secure area.

Passengers who meet these criteria should proceed to the appropriate gate and inquire about the "Same Day Connection" procedure.

Important Considerations

• Allow sufficient time for the ATS transfer and security screening, especially during peak travel periods.
• Be aware that security requirements may change without notice.
• Follow all instructions provided by TSA officials and airport staff.
• For the most up-to-date information on security screening and connecting flights at O'Hare, visit the official airport website.
