Wouldn't lack of cooperation on OP part to AA constitute "defraud AA"?

As of this point, I have yet to see if OP has realized the errors he made on his responses to the questioning by AA. I just do not see him being apologetic about what has happened. OP, there is only one person to be angry with, and that is the girlfriend. It was her actions that caused AA to look into your account on the suspicion of fraud, followed with your lack of cooperation and that ultimately caused the closure of your account. This is what you need to realize, you just don't seem aware and sorry about it.

OP, my only suggestion to you is to stay away from this forum for some time to cool off, you are being defensive towards a group that is trying to help. Make a rough draft for that HAIL MARY letter that you are planning on sending, get the address in question, have another person read the letter to see that you are not being defensive. Good luck in your quest as it will take time, it is up to AA to determine if they want your participation in AAdvantage program and bring out your account from the death, if you need to travel in the meantime, go SW, I pressume you can still use AA, just don't enter a FF # or better credit to other program, AS, BA, CX, etc.
