Flight attendants are in charge of the cabin in an aircraft, and are responsible for the safety and comfort of the passengers. They spend more time with passengers than any other airline employee, and try to offer the most personalized service possible to each and every passenger for the duration of a flight. Flight attendants can either work in first-class and provide elaborate service to a small number of passengers, or can work in economy class and provide less elaborate service to a large number of passengers. Service includes taking care of a wide variety of needs and requests, and flight attendants only have a certain time that is allotted to them during the flight in which to offer the most personalized service possible to each and every passenger.
