Some months ago, Greenpoints offered 500 AAdvantage Mile certificates in return for 2.5K Greenpoints, which was subsequently discontinued. Fortunately, some of our fellow FTers had the foresight to hold on to these certs, and redeem them now as an eligible partner.

With that said, unless you work a trade with someone who still has one, you won't be able to have Greenpoints as a partner.
