Scrutiny of the "fuel surcharge" has increased substantially as oil prices have plummeted, but YQ failed to fall in parallel. Rather than continue the charade of this being a fuel related surcharge, it's just been renamed to a general catchall addon cost.
So unlike investments, which can go down as well as up - carrier imposed surcharge only goes one way!
I wonder Simon Calder hasn't had a go about that one. perhaps he has?
