Satellite Concourses


Two new satellite concourses, S1 and S2, will play a significant role in transforming the face of O'Hare—with modern, larger new concourses nearly double the width of our terminal concourses today. They are being designed with flexible gates, to accommodate both narrow and wide-body airplanes.

During the ORD21 design competition, five of the best architecture firms from around the world submitted their visions for O'Hare. As a result of this competitive process, SOM with Ross Barney Architects and Arup were selected to develop the vision for a terminal that expresses a sense of place unique to Chicago, all while enhancing airport operations and elevating the passenger experience. 

The design for the new Satellite Concourses doubles the width of the typical passenger concourse at O'Hare while incorporating nature and daylight to enhance the passenger experience. Designed to provide for the needs of all O'Hare travelers, the concourses incorporate a variety of spaces and will optimize domestic and international blended passenger experience with operational efficiency. Not only will these modern, bright concourses add gate capacity and passenger amenities, they will enable the Global Terminal project to move forward. These concourses will be accessible via underground tunnels, O'Hare will not lose any gate capacity while Terminal 2 is being rebuilt as the new Global Terminal.​
