Also, as widely reported, the change to the CR1s (Confirmed regional upgrades) will only come into effect in 2012. Next year both rules will apply, meaning 1Ks can still earn 2 per quarter (flying 10,000 miles) and flying 75,000 miles will get you 2 and then each additional 25,000 another 2. So a 1K flying 100,000 miles can earn 12 CR1s.
