Thanks btwissel,

That helped a lot. So, its like being a roustabout (In the Police world, that swhat we call the new guys that works the beat of an officer that calls in sick or has a scehduled day off)

1. What is a bid period

2. WHat does flying thr line mea? I hear that ter m a lot. I assume it means each pilot bids a ertain work line. A Line being a work schedule (ex. Mon-Fri with Sat and Suun off). When I was a ramp agent, I thik we did something similar but that was in 1996 and I didnt really pay that much attention to it.
