Green goblin, I thought of the fact that tankering fuel would result in increased fuel burn overall, but really are we penny pinching here? Surely it's better to have too much fuel than not enough. The people that create the comapny fuel policy should have taken this into account while working closely with the people that define ticket prices.
As other ppruners have mentioned, a fuel related incident really is the last thing the rat needs at the moment. If a hull loss were to be the result of A fuel exhaustion incident there would be no airline left to speak of.
