Do you need schooling to become a flight attendant?

Yes, those wings/badges on the flight attendants uniforms are made of their hard work. They are trained extensively as their work place is not the same as if in a hotel or restaurant. They may need to swim a hundred meters depending on the airline or the airline school requires. They are even taught about social graces, etiquette, how to sit, walk, properly. They are even trained on what to do in emergency situations, such as fire, evacuation, water/terrain landings, hijackings, first aid and the like. Trained in simulators, or a situation that simulates the actual activity. They are even needed to study several books as regulations, safety, and standards are always up-to date in the airline industry. This goes to the famous quoting "My wings are a thousand books"
