No to all of those ?s. You start day one at 6 am "on call" not duty and remain "on call" until you either a.) Get called or b.) Go on days off. There are no trips to bid just days off. You can sell days off if the company needs extra pilots and you happen to be off that day. There is no scheduled flying to bid. its all on demand flying. (30min call out).
Ps. please dont turn this into a debate on 24hr "on call" being illegal. Its not. At least not in this business. The fsdo is next door and i'm pretty sure they know how it works after 20 yrs and they dont have a problem with it.
