O’Hare Unveils First Look Inside $1.3 Billion Satellite Concourse as Passenger Demand Surges
Chicago, United States — Aviation Commissioner Michael McMurray offered the traveling public its first real peek inside the new 19-gate satellite concourse taking shape at O’Hare International Airport, presenting a detailed animated video during a state-of-the-airports address to the City Club of Chicago on Thursday.
The one-minute, 43-second flythrough showcases a design led by Skidmore, Owings & Merrill that draws heavily on the airport’s origins as Orchard Field — the very reason O’Hare carries the airport code ORD. Rows of branching, tree-like columns support a sweeping, sky-lit roof meant to evoke the feel of walking through an orchard. A floating walkway for international passengers will hang suspended from those same sculptural columns, and the south end of the facility opens outward to frame views of the Chicago skyline.
“Concourse D introduces a new experience rooted in the city’s architectural legacy,” McMurray told the City Club gathering, describing a multilevel space with designated zones for dining, retail, rest and play.
The $1.3 billion project broke ground in August 2025, when Mayor Brandon Johnson joined airline executives for a ribbon-cutting ceremony. A joint venture led by AECOM Hunt Clayco Bowa is serving as the construction manager at-risk, and vertical construction is expected to begin in spring 2026. Officials say the concourse should be operational by late 2028, making it the first major concourse built at O’Hare in more than three decades.
Each of the 19 gates has been designed with dual-use flexibility — capable of serving either two narrow-body aircraft or one wide-body — a configuration aimed at maximizing gate utilization across the varied fleet types that operate out of O’Hare. Planned amenities include more than 20,000 square feet of lounge space, 30,000 square feet of commercial area and a children’s play zone.
The timing couldn’t be more critical. O’Hare is in the midst of an extraordinary traffic rebound. The airport recently reclaimed its title as the nation’s busiest by flight operations, recording 857,392 takeoffs and landings in 2025 according to preliminary FAA data — surpassing Atlanta’s Hartsfield-Jackson for the first time in years. July 2025 alone saw a record 8.26 million passengers pass through the terminals, and passenger volume through the first nine months of the year topped 63.9 million, finally eclipsing the pre-pandemic benchmark set in 2019.
United Airlines and American Airlines, O’Hare’s two dominant hub carriers, have been the primary engines of that growth. United has expanded its seat capacity by nine percent year over year and now operates roughly 604 daily flights, while American has boosted its capacity by a remarkable 25 percent. Their fierce competition for gate space has intensified the urgency behind the broader terminal program.
Concourse D is just one piece of the sprawling $8.2 billion ORDNext modernization effort. The full vision calls for replacing Terminal 2 with a new O’Hare Global Terminal designed by Chicago architect Jeanne Gang, constructing a second 24-gate satellite concourse designated Concourse E, and building an underground tunnel to link the expanded facilities. When completed, the program would add roughly 25 percent more gate capacity and a second customs and immigration checkpoint.
But the path forward has not been without turbulence. To contain costs and satisfy United and American — who are footing much of the bill — Mayor Johnson altered the original construction sequence in 2024. The revised deal prioritized building Concourse D first, followed by the Global Terminal, with the second satellite concourse contingent on remaining funds. The city committed to providing regular cost estimates and obtaining airline approval before either scaling back or exceeding the inflation-adjusted budget.
That plan, however, is already under review. Surging passenger volumes have strained existing terminal capacity to the point where closing Terminal 2 for demolition and replacement now poses serious operational risks. A December 2025 report from DePaul University’s Chaddick Institute warned of “sharp reductions” in flight activity if construction sequencing isn’t reconsidered. In recent bond documents, the city disclosed it is negotiating with airlines about reverting to the original approach — building both satellite concourses concurrently before tackling the Global Terminal.
Under that revised scenario, Concourse E construction could begin as early as 2026 with a phased opening in 2029, while the Global Terminal would break ground in 2029 and wrap up by 2033. The potential change carries cost implications that have yet to be fully quantified.
McMurray, for his part, has expressed confidence in the program’s financial footing. He noted that a large countdown clock now hangs on the wall of the Department of Aviation’s headquarters at the airport. “We can deliver it all if we do it right,” he said.
There’s also the question of Gang’s Global Terminal design, which some industry observers have criticized as overly ambitious and expensive. McMurray acknowledged that talks are underway to determine the final scope of the terminal, with one option being to economize on certain design elements. “We are collaborating with our airline partners and our federal partners. Everybody is working together,” he said.
Whether Chicago can deliver its grand vision on time and on budget remains an open question — one that will likely be shaped as much by the unpredictable pace of passenger demand as by the billions of dollars flowing into concrete and steel on the airfield.
