Very pleased to report that I earned Triple Feature miles from the targeted promo, AND just earned the "1,000 miles for $100 All You Can Earn" bonus as well, mostly from dines at the same Triple Feature restaurant.
The 1,000 miles don't appear in my dining account, but they have already posted to my UA account. Meanwhile, the Triple Feature miles have posted to my dining account, but not yet to my UA account. It will all come out in the wash....
