Whether flight attendants stay on the same plane for multiple legs depends heavily on the airline's type and the length of the route. At regional airlines, crews often stick together on the same aircraft for an entire "trip" of three or four days, flying four to five short legs per day. At major legacy carriers, the system is much more fluid; flight attendants might change planes after every leg, and they frequently work with entirely different crew members on every flight. For long-haul international flights, the crew typically stays on the same plane for the duration of the flight and the return journey after a layover, as these routes involve massive aircraft and specific rest requirements. This "shuffling" at major airlines is managed by complex scheduling algorithms designed to maximize staff duty hours and ensure that crews don't exceed their legal limits, even if a specific aircraft is delayed or rerouted.
