We've all been there: Arriving at the airport with not much time to spare and then realizing that you have to schlep what feels like miles to your gate, and with carry-on, no less (thanks bag fees!)

Now insurance company Direct Line has put numbers behind our theories and researched just how long those walks are at airports around the world, airport-int.com reports.

Looking at the distance from a terminal entrance to its farthest gate, Direct Line's research shows that it's a whopping two-mile walk at Beijing's Capital International Terminal 3 from start to finish.

Earlier this week, the Atlanta Journal-Constitution reported that Hartsfield Airport's beautiful new $1.4 billion terminal is actually a total pain to get around. As Clint Harkins told the paper: "Every time you turned another corner, you thought you were there. Well, you weren’t."

Plan ahead! Be sure to leave extra time when visiting the airports below.
