I have been flying SAS a fair bit in the last few years but have been putting my miles first on Miles and More and since the move, on KLM Flying Blue where I already had an account where I put my Delta flights (I never fly KLM). This was just a catch all account given that I didn't fly that group much. Now I am Silver on KLM (whatever). So, here is a question, if status match on SAS (Diamond), and I keep putting my points on KLM Flying Blue, what benefits will I not get when flying SAS?
