I think it's time to be honest - one of the reasons as to why some crew mind working with less crew is simply because they have to work a bit harder without getting paid for it - and getting shorter times in the bunks. Truth hurts - I know.
You quite clearly have no grasp of what it's like to fly as crew have you?
The vast majority of crew have seen no change in their workload as only the CSD's role has fundamentally changed so that blows the first part of your sentence out of the water, the bunk rest is pretty much the same as before, so that blows that part of your argument out of the water.
And according to latest traffic stats load factors we are actually carrying more passengers not less.
Remind me again how many Longhaul routes fly out of LGW?
