For the first time in a decade, the Windy City has the world's busiest airport.
With more than 585,000 flights taking off from O'Hare International Airport in the first seven months of 2014, the Federal Aviation Administration announced the Chicago airport has surpassed Atlanta's Hartsfield-Jackson International Airport as the world's busiest. It's the first time since 2004 that Chicago has held the title.
