I don't think the offer I received was something you could sign up for....I've been a RR member for a long time and did sign up for RR updates and info when I initially got the SWA Rapid Rewards card (not their credit card). I've always received email and updates from them, but, this is the first time I've ever received such a lucrative offer. A few times a year in the past I've received offers to open a SWA credit card and receive some extra RR credits, but, never two free rd trips after first purchase......that's why I jumped on it when I received it......in the future, I probably will only use that card to pay for SWA tickets and maybe car rentals for vacations since I believe those purchases earn extra credits all the time. I have another card which I use for groceries, gas, and some monthly bills and get very good rewards on that card for those purchases.
