GT - this is not BA bashing, BA is my preferred LH airline given the options from where I am. VS, QF whoever - it's not "fair" fare practice.
notdavegorman - the difference is that fuel is usually in the fare to being with. It can't be verified directly if it's a surcharge or a revenue item. Air Passenger Levies on the other hand are published information and are independent of individual carriers. My point is this: if you book two tickets on the same route on different carriers *the same taxes and charges should apply*. If not, trading standards should get physical. If carriers insist on offering fares ex tax/charge then comparison between them should be valid.
