The Project consists of an expansion and renovation of Terminal 5 at O'Hare International Airport. Ten new gates will be added at the East end of the terminal with added concessions space. An addition at the core of the terminal will add space for concessions, airline's clubs, and enlarged hold rooms. An expanded TSA security and reconfigured Customs FIS areas will improve efficiencies, along with an entirely new baggage handling system. Lastly, the West end of the terminal will be reconfigured for Delta Airlines, so the terminal will be able to accommodate both international and domestic arriving and departing flights. 


Construction of the Terminal 5 expansion began in March 2019. The first phase of the project includes an approximately $1.2 billion investment towards the modernization of O'Hare. The Terminal 5 expansion will:

  • Add 10 new gates to provide 25 percent more gate capacity, improving efficiency and reducing delays

  • 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
  • Reconfigure and improve immigration and customs screening
  • Replace the existing terminal Baggage Handling System to increase handling efficiencies
  • Support various capital improvement projects to replace and upgrade mechanical systems
  • Provide a new multi-story parking garage with additional short and long-term parking adjacent to the Terminal 5 building
