ala QF 767 vs 737 where the majority of 737 crew actually get paid more than the 767 crew, but they fly more hours for it.
The 737 get paid the equivalent to a 767 crew (on min guarantee of 80 credit hous pay) when the 737 crew fly about 70 hours/ 28 days. Next roster I fly 71.7 for my 80 credit hours*. Times that by 12 x 28 day BPs and I'm at 860 stick for the year0. I've had two sub 500 hour years over the last few years. I was also assigned 3 months leave on top of my normal leave
So you're wrong on two counts. The first is about how many hours we fly when not being assigned all our leave. The second is on how much long haul crew cost when compared to short haul. Wanna try again?
(* My credit hour rate is less than the 737 stick hour rate).
