International Connections
The O'Hare Airport Transit System (ATS or "people mover") is currently closed Monday to Friday through the winter season for construction on the modernization and expansion of our system. Shuttle Bus Service will be provided. View Flyer

The International Terminal 5 is not connected to the domestic terminals and is accessible via the Airport Transit System (ATS). If you arrive on a domestic flight and must connect to an international flight, you have two options: 1.) you can take the ATS and pass through the security checkpoint in Terminal 5 or 2.) you can take a Terminal Transfer Bus (TTB) from Terminal 3 to Terminal 5 and bypass the security checkpoint in Terminal 5. The Terminal Transfer Bus service is year round with operation hours as follows: 10:00 am - 8:30 pm. If you are arriving into the domestic terminals and need to collect your luggage (exit the security side of the airport) and recheck in T5, you will not be able to use this service.

If you arrive at O'Hare on an international flight and have a connecting domestic flight, you will arrive at Terminal 5 and will need to take the ATS to the domestic terminals. You will need to clear security again at the domestic terminals.
