Delta Air Lines will move its operations at O’Hare International Airport from the carrier’s longtime home in Terminal 2 to newly renovated gates in Terminal 5 on Oct. 12, the Chicago Department of Aviation (CDA) announced. Jamie Rhee, CDA commissioner, said the move is “the next big step” in the $1 billion expansion and renovation project nearing completion at Terminal 5, where seven new permanent gates have opened since June. In the coming months, she said, additional building elements and passenger amenities “will transform Terminal 5 into a state-of-the-art facility that will serve a mix of domestic and international passengers.” Delta will utilize gates M2 to M11 in Terminal 5’s western concourse. Its eight gates in Concourse E at Terminal 2 will be reallocated to United Airlines, which will take Gates E7 to E14; and to Alaska Airlines, which will occupy gates E15 and E17.

The existing Delta Sky Club near Gate E6 will close on Oct. 11, the last day of Delta service in Terminal 2. The airline’s new Delta Sky Club, located in Terminal 5 between Gates M11 and M14, will hold nearly 400 customers, approximately four times the capacity of the club in Terminal 2. New signage and Delta staff will be posted at Terminal 2 to direct regular Delta passengers to the airline’s new home in Terminal 5, which is accessible from the Main Terminal complex by taking a short ride on the recently revamped Airport Transit System (ATS). When complete, the Terminal 5 expansion will increase the terminal’s gate capacity by 25%, increase passenger amenity space by approximately 85%, replace the nearly 30-year-old baggage handling system, provide reconfigured and more efficient customs and immigration facilities, and increase the total number of Transportation Security Administration (TSA) checkpoint lanes to 13.
