I would highly advise anyone against listing or bidding on AA certs or Kellogg's AAdvantage 100 mile coupons on eBay.

First of all, AA will immediately send a warning letter or email to the bidder advising the offender that they are breaking AAdvantage policy. Also, AA could locate the winning bidder and make the certificates null and void...and worse, suspend their AAdvantage account. Even if the seller was not an AAdvantage member, they are jeopardizing the status of the bidders.

AA has one of the most stringent "eBay Police" and the consequences are certainly not worth the effort. Also, if you look at back auctions you will literally find hundreds of instances of people taking their eBay auctions down after they receive the AA email or letter. Several of them have posted the letter on eBay, verbatum.

The moral of the story is...it is not worth it because I would not want my AAdvantage account frozen...nor would I want to be responsible to be the one who had someone else's AAdvantage account frozen.
