I signed up for this on July 15th, and I've got several flights booked that will qualify. Basically, sign up then fly on any Copa paid flight between now and the end of September and you'll earn double RDMs. Pretty tempting right now, huh? After qualifying by September 30, any Copa flight flown through the end of the year continues to earn double RDMs. A good deal for anyone flying south who wants more RDMs, and with status it's even better. As a 1K, for example, I'll get double RDMs under the promotion + double RDMs as a 1K. Total = 3 x RDMs. Not too shabby. Plus you get to fly Copa. (Admitted personal bias, there) If you purchased your ticket prior to July 15th, you won't get the bonus, but if you have flights booked that you bought July 15. 2014 and after, you're in after signing up here.
