I believe that in orderto end up with a FF account easily, it first is not a goo idea to keep hundreds of thousands of miles : a FF account is not a savings account. If you have less than 100 000, you an get rid of them very easily, and if you are down to less than 10000, get a free magazine or let them go, over 10000, to up, get a free flight and stop flying the dreaded airline. Done this with BA, VARIG, DL and CO : all accounts are now flat or there is just one flight to take.
