Terminals 3 and 5 will undergo expansion, and a new west terminal is planned with western access into the airport; however, some land acquisition is necessary, requiring approximately 2,800 residents to be relocated. The program will expand the airport's capacity to over 3,800 operations per day, up from the present capacity of 2,700 and will vastly increase passenger throughput capacity and, ultimately, allow the A380 to operate at O'Hare.
