Flight attendants are required to put on makeup when they go to work. After all, this represents the image of an airline. When we think of a flight attendant, we can know that she is a very beautiful person. Make-up is required before going to work, and proper make-up is required during going to work. Anyway, always pay attention to your appearance and image. It's not disheveled to see a flight attendant at ordinary times. General airlines have regulations that you should use a specified hairstyle when you go to work. Nails are also very strict, and the length of nails will be calculated accurately, so if you want to make your nails fancy, forget it. Some decorations of flight attendants also have quite strict regulations, because they can't be too personalized and must be done in accordance with the company's detailed regulations.
The first impression a flight attendant gives us is a smile, so a smile is also the most basic etiquette in the flight attendant industry and the most important etiquette in the whole work. When you see a smiling person, you will feel so amiable and friendly that you will feel relaxed and slightly happy during the whole flight. Etiquette is very strict about etiquette and will undergo very strict training.
The above is the basic etiquette I know about flight attendants. I believe you may know more than I do. If you have anything to add, please write it in the comments and we will discuss it together.
