Fast facts about the world's busiest airports

Atlanta and Dubai have emerged as homes to the busiest airports in the world in a new report that looked at passenger traffic throughout major hubs.

It comes as no surprise that Georgia’s Hartsfield-Jackson Atlanta International Airport should top the charts again: This year marks the 17th consecutive time the hub has nabbed the title.

New this year, Dubai International Airport bumped London Heathrow from the top spot in the category of international passenger traffic, after seeing more than 70 million international travelers shuffle through its terminals.

Here are a few interesting factoids about two of the busiest airports in the world:
