I don't know whether you're being deliberately misleading or you just don't get it but you're close at least with the -20% compared to 330. How you can say this crap is the "same credit" is beyond comprehension - look at it the other way, if you took a third of hours off a 330 pilot right now and paid them the same hourly rate, would that be considered a like-for-like comparison to you? You are going out of your way to make the 330 (as it is) and this mythical "don't-worry-guys-it's-the-same-amount-of-work-I-promise!" look the same when really you can't compare them. The 787 deal saw away with (4 crew) night credits and, even amongst one of the worst deals QF has ever seen, the divisor was lowered to 145 to (partially) offset the loss. This 350 stuff is something else completely.
We have an agreement with our employer, there's even an agreement pre-set for the arrival of new aircraft - why on earth you'd want to go down this path is beyond me.
