Flight attendants are required to buy uniforms and to wear them while on duty. Uniform replacement items are usually paid for by the airline. Usually the airline gives flight attendants a small monthly allowance to cover cleaning and mending.
Inflight duties keep flight attendants on their feet most of the time.
To accomplish all their tasks during the few hours in the air, Flight Attendants frequently must work at top speed. At times, they must serve meals and pour beverages under rough and uncomfortable flying conditions. They must be pleasant to all kinds of people, some of whom can be annoying and demanding. Depending upon seniority, the flight attendant may be directed by a senior flight attendant or may direct the work of a junior flight attendant.
