Airport Transit System (ORD)

Airport Transit System is an automated internal transport system at O'Hare International Airport. It runs 24 hours, 7 days a week and is free for all riders. The system connects the main terminals (1 through 3), Terminal 5 (located separately from the other terminals), and economy parking.

ATS may be closed during night hours for maintenance. Shuttle bus will be provided whenever the ATS shuts down.

The system operates between the terminals outside the secured zone. At Terminals 1 through 3, stations are located across the roadway from the terminals and they can be access via overhead bridges. At Terminal 5, the station is located right outside the terminal.
