As a struggling business man who travels often I buy and sell AA related stuff on Ebay often. I have bought and sold miles, VIP's, Fly 3 certs. etc. and have never had any problems at all. All my transactions have gone very smooth. There are a few tricks to the this but the main trick is not to have very many miles in your account so if by some chance they catch you and freeze your account, just reopen another one using a diffrent address, phone etc.

I am a very firm believer that if I earned the miles, certs. etc. legitimately I own them and I have a right to do with them as I please. If the airlines don't like it then stop awarding FF miles, stop the promotions etc. and I would have nothing to buy and sell.
