Got 3 E-mails so i opted in for 10,000 miles on each.
Some time last year virgin had a few email signups including a 5,000 elevate points when you open a new account. With 6,000 elevate and a few paid transfers to other elevate accounts with matching info on milage plan accounts, I was able to get 12,500 on each of the 3 accounts. Thanks Virgin and Alaska!
