A $477.5 million extension of Terminal 1 into a formerly open area includes the first Terminal Vertical Core, which will connect the building to a pedestrian walkway to the future CTA Center Automated People Mover Station. The new construction also includes a bus port, and additional ticket counters and baggage carousels, plus restrooms and a service-animal relief area.

Gates 20-28 are now part of Delta’s new Terminal 3 complex, and can be accessed from Terminal 3. WestJet customers can continue to check-in at Terminal 2 and access their gates from Terminal 3.

The first three gates in the new Terminal 3 are now open, with more gates and concessions coming soon!

Delta and Aeromexico check-in and departures are from Terminal 3. WestJet departures are from Terminal 3.

The $1.6 billion modernization of Terminals 4 and 5 will include a unified departure hall and a new south concourse in Terminal 4 with additional space for hold rooms, concessions, restrooms and a bus gate that will serve both domestic and international traffic. Improvements will be made to the north concourse and Terminal 5.
