Another thing that came up is that due to the first fare letter across saver to flex, you will earn the same amount of miles with Flying Blue on Aeroflot flights. Thus, whether you pay the promo fare or the most expensive economy class, the miles will be the same. The same rule applies to two Business Class bands.
I called Flying Blue about this, but their scheme will not change along with Aeroflot's change. It does not seem logic to me though.
