Some 13,434 O’Hare departures were canceled through the first 11 months of last year, according to data provided by the federal Bureau of Transportation Statistics.
The O’Hare cancellations far exceed the number at any other airport. In fact, they represent more than double the flights that were scrubbed at the world’s busiest airport, Hartsfield-Jackson Atlanta International Airport, which racked up 6,196 flight cancellations during the same period. O’Hare placed second, behind Hartsfield, for total flights last year, according to the Federal Aviation Administration.
Only 1,172 flights were canceled at Midway from January through November last year, according to the transportation bureau. One percent of Midway departures were canceled.
