Coming back, full circle....been an interesting thread. The problem, as I see it anyway, is that you have enough - just enough - fuel to commit and the company gives you no more with their statcon. All fine and dandy and you end up, as the previous poster says, knowing what fuel to leave the hold with for your alternate and what fuel you need to leave the desdi hold with to leave such that you arrive with final reserve (or, as I prefer, final reserve plus a 'sneeze factor'). You take your choice, committing as we did to DXB and then you are suddenly sweating because somebody turns up with no holding fuel and gets priority! No that is a game changer! The question should be asked straight away, what is your alternate? Why have you no fuel?
I do feel that we, as pilots, need to communicate the fact that we are about to commit to destination so that the controller knows that he will end up with multiple maydays on his hands potentially should he then start changing the rules........
