Plans to expand the main runway at Chicago’s third commercial airport have hit another delay. The latest estimate now places completion in September next year.
Gary/Chicago International Airport
At first glance Chicago seems much like a handful of other large metropolitan cities–a pair of airline hubs surrounded by a smattering of general aviation reliever fields. But in Chicago’s case, the center of the airspace is O’Hare International Airport, the world’s busiest (909,530 operations last year). Chicago’s second hub, Midway, relinquished that same title to O’Hare in the 1960s.
