Terminal 5 Expansion and Modernization

Renovations at T5 Near Completion

Construction on the $1 billion expansion and renovation of Terminal 5 began in March 2019. The project will open in phases throughout 2023.

Seven new gates opened in the extended East Concourse in summer 2022, and ten renovated gates opened in the West Concourse in October 2022 as the new home for Delta Air Lines, which shifted operations from the carrier's long-time home in Terminal 2. Delta's move also included the construction of a new Delta Sky Club, located between Gates M11 and M14, with more than four times the capacity of its former club in Terminal 2.

Upon completion, the Terminal 5 project will:

  • Add a total of 10 new gates to provide 25 percent more gate capacity, improving efficiency and reducing delays
  • Increase passenger amenity space by 85%​​
  • Expand the existing building by approximately 350,000 square feet
  • Renovate more than 750,000 square feet of the existing building
  • Add more airline lounge space
  • Add more concessions and passenger amenities for an improved dining and shopping experience
  • Enlarge, reconfigure, and refurbish interior spaces
  • Integrate new furniture and new technology throughout the facility
  • Expand security checkpoints to 13
  • Reconfigure and improve immigration and customs screening
  • Replace the existing 25-year-old Baggage Handling System to increase handling efficiencies
  • Provide a new, six-story parking garage with additional short and long-term parking adjacent to the Terminal 5 building
  • Multiple roadway enhancements to increase lanes and alleviate traffic bottlenecks
  • An expanded curbside area to enhance drop-off and to help passengers move more easily between Terminals 1, 2, and 3


In May 2022, the Chicago City Council approved the largest set of concessions agreements at O'Hare in more than a decade. Local favorites like Butcher and the Burger, Sparrow Coffee, Bar Siena, Hampton Social and more are coming to the expanded amenity spaces in Terminal 5. Mobile ordering from food and retail concessions with the option for gate-side delivery is also available throughout the terminal. 

The approved agreements, which also included retail offerings in Terminal 5, will achieve an Airport Concession Disadvantaged Business Enterprises (ACDBE) participation rate of 40%, exceeding the CDA's goal of 32% and the nationwide goal of 10% set by the Federal Aviation Administration (FAA).
