My AA flight leaves March 5, and I just realized I better sign up for their frequent flyer program. While signing up I see a promotion code box (so I'm holding off for a couple days). Googling "AAdvantage promotion code", I see past deals to get extra miles if I sign up for newsletters, or someone refers me. I couldn't find anything current, but perhaps you have a promo code to give me to benefit us both, please PM it to me, or if there is a general promo code, please post a link to it here. Thanks in advance.
