Vin Diesel,
I doubt that unless you fly yourself or work for an airline, it would be very difficult for anyone to explain rostering to you. Your example of 22 weeks a year really does show up the level of your understanding.
The fact that the pilots seem square behind these crew, unlike in BA where I work, speaks volumes to me, because it is an indication of this change being made unfairly.
It would be interesting to hear a bit more detail I will agree but noone would have the time to explain rostered and duty hours to you in enough detail for you to understand, I fear, without boring everyone else to death.
