About Terminal 3

Terminal 3 at Chicago O'Hare International Airport is one of the airport's four passenger terminals, serving as a major hub for American Airlines and its regional partners. The terminal opened in 1961 as part of O'Hare's original infrastructure development.

Terminal 3 houses gates G1-G19 and H1-H22, accommodating both domestic and international flights. The facility underwent significant renovations in the early 2000s, including improvements to passenger amenities, security checkpoints, and gate areas. The terminal features modern architectural elements while maintaining functionality for high passenger volumes.

American Airlines operates its primary O'Hare hub from Terminal 3, with connections to destinations across North America, Europe, and Asia. The terminal also serves American Eagle flights and select partner airlines. Passenger services include multiple dining options, retail stores, business lounges, and ground transportation connections.

Terminal 3 connects to other terminals via the Airport Transit System (ATS), an automated people mover that provides efficient inter-terminal transportation. The facility processes millions of passengers annually, making it one of the busiest terminals at O'Hare.
