there were 22 scheduled departures: six United 727s to MSP, DCA and LGA, 12 Northwest 727s to MSP and CLE, one Delta DC-9 to STL and three Ozark FH227s. The December 1970 OAG shows 86 weekday arrivals (77 jet) on 13 fixed-wing airlines from 31 airports, but the August 1974 shows 14 arrivals (all jet) on four airlines, and in 1976–79 Midway had only the two or three Delta DC-9s from St Louis. Midway Airlines arrived on October 31, 1979, with DC-9 nonstops to Kansas City, Detroit and Cleveland Lakefront; they expanded greatly in the 1980s. Their September 1989 timetable shows 117 weekday departures to 29 cities, plus 108 departures on their commuter affiliates to 22 more cities. Midway ceased flying in 1991 due to financial challenges. In 1982, the city of Chicago purchased Midway Airport from the Chicago Board of Education for $16 million. Three years later, Southwest Airlines began operations at Midway. Midway was a focus city for Vanguard Airlines from 1997 to 2000.

Unlike the CTA Blue Line, which runs 24 hours a day, every day, the Orange Line runs from about 4:00 am to 1:00 am, just shy of 24 hours, at an average of 8-minute intervals. During overnight periods, the N62 Archer bus is available as an alternative. Once the train departs, the trip from Midway to the Loop takes about 25 minutes. Years of ATA (1994–2008) In 1996, after failing to get his Lake Calumet Airport and having received harsh criticism for the idea of turning the airport into an industrial park, Chicago Mayor Richard M. Daley announced the Midway Airport Terminal Development Program, which was launched the following year. At the time, it was the largest public works project in the state. The Midway Airport parking garage opened in 1999, bringing covered parking to the airport for the first time. The garage is connected to the Midway terminal building for convenient access to ticket counters and baggage claim areas. Continuing with the expansion project, a pedestrian bridge over Cicero Avenue was built in 2000, connecting the new
