I received a mailer for the triple miles for certain purchases (groceries, dining out, etc.) promo that ran through 9/30 and was discussed in another thread. (My threshold was $650/month.)

Today, though, I received a mailing saying I can earn double miles on all purchases in these categories over $250/month from 10/1 through 12/31. Pretty smart--I was just thinking today that I need to stop using UAL for non-quick service restaurants (so I get triple points through that promo) and return to my *wood Amex for the bulk of my purchases. Now, though, I have to recalculate whether 2 UAL miles is worth more than 1 *point. Either way, though, I'm glad to see that some sort of UAL promo will continue through the end of the year, and that my threshold is lower for this one!
