Certainly stand to be corrected. I am only repeating what i have been told by Qantas pilots. Just goes to show they may be somewhat prone to exageration.
Up to 1 hours duty (duty being 1 hr before STD to chocks on, i.e 11hrs stick) we have two pilots with some minor variations for number of sectors and time of flight. Over that we have 2 Capt 1F/O. On some flights i believe we have 2 capt and 2 f/o, but that is only because the second crew operate a shuttle the next day.
I don't operate ULH so the above may some small errors but basically correct.
