Distance depends. Ours was scheduled for (if I remember right) about 5,000 miles a week. We'd always take extras, tho, which was almost everyweek so that brot us over 6,000 p/w.
Some, I've heard, were less than 4,000. Just depends on where you are, where you go, how much you wanna do.
Pay? Everything's per mile, whatever rate is now (been retired 4 years now so don't know) and with us, it was HUB mile. I heard there was some argument about SCHEDULED or HUB.
Delays are by the hour. When we got to furthest point on first leg, we had to give 2 hours if we had to wait. After that, everything was delay. ANY turnaround is delay/pay per hour.
More?
