If the change of wording from fuel surcharge to carrier surcharge actually affected the amounts SE pay significantly for their redemptions, I'd be pretty ticked off if I were an SE.
As it goes, I think you might be getting a little ahead of yourselves on the matter. Given that if the above were to be true, it would amount to flagrant mis-representation and outright dishonesty from the Ben's given the ho had the yq reduction perk got, I doubt they'd be able to show their face in here again.
Therefore I doubt it's veracity at this stage.
