During a recent trip to our local Costco, I noticed the American Airlines gift cards that you pay around $270 for a $300 gift card. Seems like a great way to save $30 per person, but I was wondering if anyone else had used these? I am just wondering if there is a catch. The web site says gift cards are for flights originating in the US so I was wondering if round trip from US to Aruba would count for that. I figured I would check here before I called American.
