For the 17th year in a row, which U.S. city had the busiest airport?

Once again, the Hartsfield-Jackson International Airport in Atlanta took the honors. More than 96 million travelers flew to or through Atlanta last year.

The usual suspects finished in the top once again as well: Los Angeles, New York, Chicago’s O’Hare,  and London’s Heathrow Airport.

But who came in at number two? Beijing capital international airport, with a staggering passenger load of 86 million travelers.

In total, 6.7 billion—that’s right, billion—passengers passed through airports worldwide, and that number is expected to only get bigger.

One interesting fact—China is building about a dozen mega airports the size of Beijing.

The U.S. hasn’t had a new major airport in more than 20 years—and that was Denver, back in 1994.
