If the prediction in the Chicago Sun-Times proves true, O'Hare will retain the title of world's busiest airport, but O'Hare is also on track to be the nation's most delay-plagued airport with nearly 30 percent of its flights this year either landing or taking off behind schedule.
According to the Federal Bureau of Transportation Statistics, O'Hare logged nearly 911,000 takeoffs and landings through the end of last month. Its closest rival, Atlanta's Hartsfield-Jackson Airport, logged slightly more than 884,000 flights during the same 11 months.
Hartsfield-Jackson, however, handled more passengers, 28.1 million. O'Hare was in second place with 23.3 million.
