Before you get creeped out by this confession, take a second to understand it. But flight attendants admitted to googling every passenger on their flight. They have access to a list of every passenger's full name and seat number, so it's easy to do a quick google search and find information about every traveler. Though it's not necessary or for any particular security reason, it is simply entertaining for those who are bored during the flight.
Kind of bizarre and flattering, but remember, flight attendants are humans just like everyone else. And when boredom strikes, google is there to rescue. Just make sure your social media accounts are private.
