Which of the following best describes a "duty period" for flight attendants?

A "duty period" for flight attendants is defined as the elapsed time from when the flight attendant reports for duty until they are released from duty after their work is completed. This includes all tasks and responsibilities that a flight attendant must perform during their assigned shift, which encompasses pre-flight duties, in-flight services, and post-flight tasks.

Choosing this option reflects an understanding of the comprehensive nature of a duty period as it encapsulates the entire work commitment, which aligns with regulatory definitions in the airline industry.

In contrast, flight preparation time before departures, time spent during in-flight service, and hours available for rest between flights do not fully capture the scope of a duty period. These aspects may constitute parts of what flight attendants do, but they do not account for the entire period of duty as outlined by industry regulations. Therefore, B is the most complete and accurate description of a flight attendant's duty period.
