I just got the magazine offer and it seems to have been cleaned up. It just says final notice before 12/15/07 and must be postmarked by the same but in the body of the letter it only says "Don't let your CO OnePass miles remain unused any longer.......

No more threats of expiration.

But it did get me to look at my account which I have not used for some time and I am worried about losing my existing miles. So I just signed up for the 20k credit card promotion.
