Great job AAL and Mastercard for honoring the deal. Really good holiday gift - not just to ourselves, but also Conservation International who were likely delighted to receive a surge donations!

I capped myself at a few hundred dollars for this promo. Since I knew I wouldn't stomach losing more if this didn't go through and there would at least be a tax write-off. Though this is a good lesson to everyone who thinks to "go big" in these deals or potentially next time: don't throw cash into something you're not willing to lose. Investing 101.
