Atlanta’s Hartsfield-Jackson International Airport is known as the world’s busiest airport, serving over 250,000 passengers daily and over 900,000 flights in the course of a year. Now, it has another distinction:

The most popular place on Foursquare.

Today, Hartsfield-Jackson became the first location (of any type) to ever log 1 million check-ins. As of the writing of this article, Hartsfield-Jackson has 1,001,776 total check-ins from 280,746 different people. Foursquare users have also left nearly 2,500 tips for the airport and uploaded over 7,200 photos.

In honor of the milestone, Foursquare is sharing some interesting stats about the airport based on its 1 million+ check-ins.

For instance – Terminal B sees the most traffic, and Mondays is the busiest day to fly. One Flew South is the most popular restaurant inside the airport, and people love to look at a particular collection of Zimbabwean sculptures while they wait.

Foursquare has also provided a heatmap of check-ins at the airport, no doubt coming from their 500M check-in map project, just launched last month.

Cool stuff.
