What does a 'reserve line' consist of?

A 'reserve line' consists of a schedule indicating reserve availability and assignments. In the context of airline operations, a reserve line is designed for flight attendants who are not assigned to a regular flight schedule but are available to cover trips as needed. This flexibility allows the airline to maintain operational efficiency, particularly in the case of last-minute crew changes, unexpected absences, or scheduling conflicts.

Flight attendants on a reserve line may receive notifications about assignments on short notice, which is crucial for ensuring that flights are adequately staffed. This type of scheduling is particularly important in the airline industry, where demand can fluctuate unexpectedly, and the need for crew support can arise quickly.

The other options do not accurately represent what a reserve line entails. A detailed list of flights planned for the day pertains to scheduled flights, not reserve assignments. Emergency procedures focus on safety protocols rather than crew scheduling. Lastly, the hours worked by active flight attendants refer to logged flight hours, which do not specifically capture the concept of availability and random assignment inherent to a reserve line.
