To keep it short and sweet, the social media policy says you can't publish social media content containing anything to do with the airline or airline property unless specifically authorized. Some day when you land a job at an airline/corporation, you'll come to learn that major corporations have strict policies on individuals putting out content on social media platforms that represents not only yourself, but the corporation as well. i.e. if you make a rap video while decked out in an AA uniform and AA logos and emblems, you're representing AA in doing so. This kind of activity is strictly prohibited in the social media policy.
