So I'm hoping to get -900 in NY. Can anyone tell me how often one flys on reserve? Being new to the airlines I always assumed reserve was used if someone called out sick or didn't make their commute and so I figured you weren't called in very often. But reading this thread it seems you fly fairly often on reserve. Can anyone shed some light on why that is? I would think if there are so many more flights they would make more lines to bid.
