There is nothing about plastic surgery in the flight attendant medical examination standard. When choosing a flight attendant, as long as the temperament, height and appearance meet the standards, they may be selected. Flight attendants can't have scars, which means that the skin exposed to the outside of clothes can't have obvious scars. The scars of plastic surgery are generally hidden and not easy to see. So you can try. Plastic surgery will not affect your application for flight attendants.
