These people are scammers. Don't get invloved. They use a false information to obtain cards and then run up balances that they never intend to pay. They tell you that it's from Business Extra but they are only buying the miles and putting them in your account. The miles are purchased at AA.com. That's why it's 40,000 miles. You are allowed to buy 40,000 and to gift 40,000. I know about this from another Flyertalker who will go nameless here. He got scammed. These peole are common criminals. In fact, you should tell AA and ask to have them investigated.

STAY AWAY
