wow thanks for your very extensive and detailed explanation Irishguy28.
The issue came after a wrong information given me by the AZ MilleMiglia customer service: an F ticket on AF gives 200% award miles but only 100% status meiles.
Thankfully I see on your calculation that this was wrong and F tkts give 200% status miles too! that makes more sense.
I think this was a very basic information that MM customer service representatives (answering the CFA+ dedicated line) should - or better say MUST - know!!
I do totally understand and agree on the status bonuses not applying for flights on other airlines..
