If Riley wants to fly, but she has vision issues and other health problems that prevent her from being a pilot, she should try to be a flight attendant.
A flight attendant is a member of the crew whose main mission is to monitor the safety of the flight and the comfort of the passengers.
The only educational requirement for the position of flight attendant in the United States is a high school diploma or equivalent. Once selected, the airline will train her in a 3 to 8 week training program.
