I know a lot of people have posted about this but I first saw this at The Flight Deal.
American Airlines is running a contest where you have a chance to win 2 first class round trip tickets anywhere they fly. You have to watch 6 videos and answer a question at the end of each video. Honestly, the questions are easy enough that you don’t have to actually listen to the video if you know anything about American Airlines and frequent flyer programs in general. The videos are short, between 1 and 2 minutes in length each.
Besides the the 10 or so minutes it takes you to complete the videos and questions, there is no downside to this. 1,000 miles isn’t a lot but its better than nothing. If you don’t use your AAdvantage account often then this is a great way to extend the life of your miles.
