Terminal 5 Expansion and Modernization

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

Upon completion of the new gates, Delta Air Lines will relocate to Terminal 5 from its existing location in Terminal 2. The move enables Delta and its SkyTeam alliance partners to mix domestic and international arrivals for use by foreign and domestic carriers, consolidating their operations into the same terminal to provide a better traveler experience.

Future phases of this project will include additional parking capacity, improve roadway capacity, and will expand and enhance curbside capabilities including:

Additional improvements to the 25-year-old baggage handling system
An expansion of the parking garage to augment existing surface parking and to yield additional spaces adjacent to the terminal 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
