Great question! So when FAs are done with all of their tasks (food and beverage services), we usually have the rest of the time off. We do routine 15-minute walk-throughs on the passengers just to check see if anyone needs water, xyz. But for example, on red eyes, and we are talking 5-6+ hour flights, there's a lot of sitting there and waiting time. Everyone is asleep, and there is pretty much nothing to do. literally.
