ATLANTA -- Besides being the busiest airport in the world, Hartsfield-Jackson is now among the most social.
"I get on at least two or three times a day," Breanne Coe said from the Hartsfield-Jackson Atrium. Others check it every time there's a lull. It's the lure of Facebook.
Second only to LAX, Hartsfield-Jackson was named the most social airport. It doesn't look that social. But this is the age when social doesn't mean talking to each other: It means heads down, fingers working.

"It is kind of sad," passenger Emily Gaudian said. "You are so much more personable when you don't have that phone in your hand and you're not in three different conversations at once."
Hartsfield-Jackson Atlanta International Airport got beat out by Los Angeles International Airport. Chicago O'Hare International Airport, San Francisco International Airport, Dallas/Fort Worth International Airport and Denver International Airport round out the top five.
Facebook found that there's also an increase in check-ins during the holiday travel rush. Last December, check-ins were up 20x the normal average on the 18th of that month with spikes also occurring on Dec. 23rd and Dec. 24th. Airport check-ins quieted down after Christmas on the 25th but then saw an increase on Dec. 29th through Dec. 31st as people traveled to their New Year's Eve destinations.

Facebook tabulated data from people check in in at airports on Facebook and through third-party location services that have integrated with the Facebook Places API between August 1020 and November 2011.
"Well, when you say it like that, it does sound a little creepy," Coe said. "but I guess we do it to ourselves because we check in everywhere."
Law enforcement and safety experts have long warned Facebook users to beware of the "check-in" button. You may not want everyone on Facebook to know you're going out of town. But sometimes those security settings as get confusing. Here's how to disable the Facebook Places option:
The Facebook Places security options are set to "Friends Only" by default, but you can opt out of the service altogether. To do so follow these simple instructions:
1. Go to your Facebook account's "Privacy Settings."
2. Click "Customize settings" in the "Sharing on Facebook" section.
3. Under "Things I share" click the option box next to "Include me in 'People Here Now' after I check in." You have now disabled this feature.
