I`m currently Millemiglia member and thinking about switching to FB. From what I understood KLM gives only 25% of mileage for some of their fares

. I`m going to fly Continental S class and it seems that it`s a 100% mileage credit. If it`s really true it seems quite unfair that KLM is doing it to their FBs, don`t you think? Or I got it wrong?
