Trafalgar:
Not at all; but it is necessary, every now and then, to try to add a little realism to the incessant, mindless ranting that frequents these pages!
I am as equally anti 3-man ULR as you; however, what I am certain of is that CX will change the rostering (dare I say it -PRACTICES) that it empolys to accommodate the reduced crewing. They are acutely aware of the impact down-route sickness would have on the operation.
Who is to say that we would not find rostering similar to BA/VS?
You are however, correct in your assertions about 5 year fleet swaps, though of my mates in BA, I don't see too many bidding to the A320 from the A380/744, even with 3 man ULR!!!!
But if you are so adamant that being able to swap fleet is a good thing, why don't you petition Anna and the board to fully incorporate KA into CX and then you could have a stab at your 'breaks' periodically.
