Iberia 25% Off Transatlantic Awards and Low Surcharges

British Airways is offering a 25% discount on its longhaul awards--flown by BA or Iberia. That would be great except British Airways charges humungous surcharges that make any redemptions an awful deal in my mind. To wit, British Airways business class from New York to London:
As the screen shot indicates, this is normally a 40,000 Avios award, so there is a 10,000 Avios, or 25%, discount. But the taxes and fees of $438 oneway make this an award I would not purchase.
