Would appreciate any input anyone has to see if I have a legitimate case against American Airlines for taking almost 54000 miles from my Advantage account for what they claim was a violation of their Terms and Conditions.
I posted my miles for sale on Craigslist last month. I had several interested buyers wanting to buy the miles I listed. The first potential buyer called and was ready to Paypal me the money if I would transfer my miles into his account. As I got on the AA website to do this I quickly read the Terms and Conditions that stated the miles could NOT be sold or bartered. I contacted him by email and stated "I am sorry. After reviewing the T&C with American Airlines I can not sale the miles because its in violation of their agreement" I also emailed other buyers stating "the was listed for sale in error and I could not sale my miles" I deleted my post and NEVER sold my miles. (I could have probably ten times in the first two days)
AA Corp Security found my Craiglist add and said I was in violation of the contract and as a result they were taking the number of miles I tried to sell as a penalty (they actually took 889 more miles)
I forwarded my emails that I had sent BEFORE they notified me and explained that I did not sell the miles and pulled the sale from the site for consideration.

My argument is that the Terms and Conditions states tickets will be void if they are sold or bartered and it was a violation to sell them. I never sold my tickets. I did solicit them but, never sold them. I have read the agreement carefully and nowhere does it say its a violation to solicit the miles only to sell them.
I feel strongly about my desire to fight them on this because I did the right thing and refused to sell these when I re-read the T&C. I maintain that I did indeed solicit them for a couple days but, did not sell them when I easily could have.
Do I have a case in Small Claims for this?
