Status doesn't work if I'm not flying on that FF #, right? that is to say, there's no point using 4000 upcoming flight miles to earn annual silver on Aegean unless my future *A flights are going to be on my Aegean FF#... and with about 50,000 CO/UA miles in the bank and Aegean's lower earning capacity that doesn't make much sense.
Please correct me if I'm wrong about this.
