What is a 'swap' in the context of airline scheduling?

In airline scheduling, a 'swap' refers to a trip trade that involves crew members exchanging their scheduled flights, which commonly occurs when both parties have open time. This allows flight crew members the flexibility to adjust their schedules based on personal needs while ensuring that operational requirements are still met. Such swaps are integral to crew management as they maintain compliance with scheduled duties and required rest periods while accommodating crew members' preferences or changes in personal circumstances.

The context of open time is significant here; it refers to periods where crew members are available to work but do not have assigned flights. These swaps can optimize scheduling, balance workload among crew members, and enhance work-life balance.
