Mayor Brandon Johnson unveiled the design of Satellite Concourse 1, the first major component of the once-in-a-generation expansion and modernization project known as the O’Hare 21 Terminal Area Plan. The new concourse, which will serve both international and domestic passengers, is one of the largest components of O’Hare 21, a curb-to-gate transformation of O’Hare’s terminal complex into a modern, efficient global hub designed to create a more efficient and comfortable experience for travelers. Architectural renderings for Satellite Concourse 1 released by the City showcase a unique design led by renowned Chicago architects Skidmore, Owings & Merrill (SOM) with Ross Barney Architects, Juan Gabriel Moreno Architects (JGMA), and Arup. Satellite Concourse 1 adds 19 new gates and is designed to flexibly accommodate different sizes of aircraft bodies, increasing operational efficiency for carriers and reducing layover transfers for passengers in one of the nation’s busiest airports. Work begins this summer on a stormwater project that will support the future elimination of a detention basin west of the future satellite concourse to an expanded basin on the southeast end of the airfield. The current timeline calls for the completion of the Satellite Concourse 1 as an extension of Concourse C in 2028.
