From the price it would seem the fares I was looking at were in fact D "discount" business, though I don't see a way to confirm this at s7.ru, at least not on the flight selection page (nor is there a way to choose between the three, perhaps the price just goes up after all D or C seats are taken?)

Anyone know if BA's earnings table (J C only) is from the time D used to be(?) an upgrade class, or does S7 discount business really come with zero BA miles and tier points?
