Growth in population and income is expected to lead to an increase in the number of airline passengers. Airlines enlarge their capactiy by increasing the number and size of planes in operation. Since Federal Aviation Administration safety rules require one attendant for 50 seats, more flight attendants will be needed. Assignments are based on seniority. Usually only the most experienced attendants get their choice of home base and flights.
Some attendants transfer to flight service instructor, customer service director or recruiting.
