What is the role of a reserve crew in airline operations?

The role of a reserve crew in airline operations is primarily to remain on standby for flight assignments. Reserve crew members are not scheduled for specific flights in advance; instead, they are available to step in as needed, providing flexibility and ensuring that staffing levels meet operational demands. This is especially crucial in scenarios where there are last-minute changes, such as flight delays or crew illness, which can arise unexpectedly. By having a reserve crew ready to be called upon, airlines can maintain service reliability and safety without overstaffing during slower periods.

In contrast, operating flights directly, conducting in-flight services, or overseeing baggage handling are specific roles that require scheduled assignments or dedicated crew members, rather than the standby nature of reserve crews.
