Via this thread on Flyertalk, you can earn 1,000 Rapid Rewards points just for watching a short 2-minute tutorial video on how to use your RR points. You must have a Chase Southwest Airlines credit card in order to receive the points.
Head on over to this website, and click through the video. Don't start the video and leave because it pauses a number of times during playback to wait for your click to continue. At the end of the video, you will be asked to enter your Rapid Rewards number and the last 4 digits of your Chase Southwest Airlines credit card number. This offer may be targeted, since I did also receive an email about the promotion with a unique link to the website. However, many people on Flyertalk have reported success despite not receiving the email. Others have said they received the error notice "The information you entered is not recognized. Please reference your printed offer." So perhaps certain accounts are not eligible.
Watch the video and complete the promotion page by November 1, 2011. Points should post 6-8 weeks after the promotion ends.
