(Chicago Tribune) — Commercial flights are starting up again at the city’s two airports following the grounding of almost all planes since Tuesday afternoon, but already there have been a number of cancellations. At 8:30 p.m., the Chicago Department of Aviation reported more than 1,100 flight cancellations at O’Hare International Airport and about 40 at Midway Airport. ”Today is expected to be a very busy travel day at both O’Hare and Midway as airlines rebook passengers and work to resume full operations,” the aviation department said.
