I don't know why you're worrying about the new ZFW procedure. I have yet to meet a single 747 pilot or any dispatcher who has seen fuel reduced in this way. It just doesn't happen. If you don't like the fuel figure take more. I always do and have never been overruled by another crew member except to take even more extra fuel. The BKK incident is unfortunate but having your destination close due weather and your alternate close due to a broken aircrft on the same day is hardly something you can plan for except by choosing another alternate, an option which remains open to you at the briefing stage by simply asking for a flight plan with a different alternate. I have never had one refused. In short, if you want more fuel, take more. If you worry about league tables then join the majority of your colleagues who give them the scant attention they deserve.
