About

​​​The City of Chicago and its airline partners are moving forward on a historic plan that will transform O’Hare International Airport with the biggest terminal expansion ever. A new Terminal Area Plan for O’Hare will completely redevelop the terminals and concourses, with Terminal 5 to undergo an upgrade and expansion, Terminal 2 to be largely demolished and rebuilt to include a brand new international arrivals facility, and renovations made to Terminals 1 and 3.

The upgrades are set to grow O’Hare’s overall terminal square footage by more than 60 percent, from 5.5 to 8.9 million square feet, and increase gate frontage by 25 percent.

Please visit the Frequently Asked Questions (FAQ) section for more information.

 ​​​The new Terminal Area Plan is central to the Airline Use and Lease Agreement signed by the City and airlines in spring 2018. Click here to view the O'Hare Airline Use and Lease Agreement​.​
