The survey only takes a couple of minutes and asks you about your preferred loyalty programs. The miles should be deposited into your account within 6-8 weeks at most, per the page at the completion of the survey.
The promotion is apparently valid through December 17, 2012, or to the first 200,000 entrants.
This is the most rewarding and easiest loyalty program survey I’ve taken in a long time.
