(Your reaction) Thank you!

Landing second to Atlanta on this list, it's jump in traffic over the last several years can be credited in part to the massive terminal that the facility added to accommodate the 2008 Olympic Games.

10. Hartsfield Jackson Atlanta International (ATL) - 95,462,867

(Your reaction) Thank you!

Anyone who has flown into or out of the number one spot on our list knows that it takes the cake for the most passengers. Hartsfield Jackson Atlanta International has held this spot since 1998, and has also led the way in landings and takeoffs since 2005.

This sprawling facility is a major focus spot for Southwest Airlines, and the host of Delta Air Line's corporate headquarters. The airport will soon widen some sections of its midfield taxiways to accommodate the enormous Airbus A380 aircraft, which will likely attract more airlines. Korean Air is scheduled to begin service to Atlanta on September 1, 2013, and Air France is considering doing the same.

As the world economy and the nature of travel itself evolves, this list will continue to change over the next decade and beyond. What's your favorite airport to spend a layover?
