O'Hare Airport's $12.5 Billion Overhaul Moves Forward With New Timeline

Chicago's O'Hare International Airport (ORD) is undergoing a massive redevelopment program, “ORDNext,” with significant construction underway. The project, valued at $12.5 billion, aims to modernize the Airport and enhance its competitiveness.

Key Components of the ORDNext Expansion

The ORDNext program includes a new Global Terminal and concourse on the site of Terminal 2, two new linear satellite concourses southwest of United Airlines' Terminal 1, and a new underground train and walkway system. Upon completion, the airport's terminal area will expand to approximately 220 gates, a significant increase from the 185 gates in 2018.

The city views ORDNext as crucial for American Airlines and United Airlines, both hub carriers, who are eager to expand operations. However, growth is currently limited by a Federal Aviation Administration order capping flights through at least October 2027 to manage congestion, prompting airlines to utilize larger aircraft with more seats.

Concourse D Opening and Global Terminal Delay

The next phase, Concourse D, is slated to open in two years, by the end of 2028. Connected aboveground to Concourse C, it will feature 19 gates capable of accommodating both twin-aisle and single-aisle aircraft. However, international arrivals through Concourse D will be unavailable until the Global Terminal is complete.

Construction on the Global Terminal is now scheduled to begin in 2029, with an opening date projected for 2034—six years later than initially planned. Designed by a consortium led by Studio Gang, the terminal will streamline passenger transfers between international and domestic flights, potentially eliminating the need to leave the secured area. The design also aims to showcase Chicago's identity to travelers.
