According to msnbc.com, the airport where the most travelers "check in" on Facebook, or a third party application, is none other than Los Angeles' LAX Airport.

In a report released by the social media giant, Atlanta, Chicago O'Hare, San Francisco, Dallas-Fort Worth, Denver, Sydney (Australia), Phoenix, Las Vegas and Suvarnabhumi (Bangkok, Thailand) all followed suit to make up the top ten most social airports on the planet.

"Travel is inherently a social thing," said Travis Katz, founder and CEO of the social-travel site Gogobot.com. "People check in at airports because they want to let people know they're leaving home or landing somewhere new."

That desire may also explain some of the report's other findings. Last year, check ins were 20 times higher than average on Dec. 18 with additional spikes occurring on Dec. 23 and 24, presumably as people headed to the airport to catch holiday flights.

After Christmas, the chatter died down again before spiking between Dec. 29-31 in anticipation of New Year's Eve.

Unfortunately, Facebook didn't suggest why LAX was the most social airport, although one could be forgiven for thinking the city's celebrity culture might play a role.

"Checking in is a self-serving sort of activity and L.A. is a hotbed of self-centeredness," said Nick O'Neill, founder of Holler.com, a location-based mobile planning and search app. "Celebrities and people like that are all about broadcasting about their awesome lives."
