And the duty pay starts from pushback not "sign on" which is absolute crap. Could have a very lengthy delay and get payed ZERO extra for all your hard efforts and time.
In fact, because you are now delayed and arrive at your destination later and have a shorter layover, they'll actually take your allowances away!!
WRT overtime, not a fan of the total duty time averaged out over the month either.....and not payed for each individual sector.
