AFAIU there are changes coming up to Marco Polo/AsiaMiles, and one of them is that registered accounts – which are neither Marco Polo nor AsiaMiles accounts – will be dropped. I had no idea you could get an account and NOT be a Marco Polo ir AsiaMiles member but there you go. That's why they push holders of such accounts to register with AsiaMiles, giving them 300 miles and MP Green status, for free (I remember paying 50 bucks in 2007...)
