I normally hate these threads, but this one seems particularly pertinent. One of the ways foreign (esp. European) carriers devalue their programs is to add fuel surcharges and various taxes and fees to their frequent flyer redemption tickets. US Carriers haven't done this, which is one reason they remain such a good deal.
With DL now going this route, do you think it's likely AA will follow?
