Just finished my 4th stay. Some bonus miles (points) already posted to my Southwest Rapid Rewards account. Is turning out to be a very convenient way to round out my existing credits to redeem for my last standard award. Previously, I have never had a problem with Wyndham miles & bonuses posting to DL, NW or AA.
I decided this was the best way to utilize my Wyndham account for some needed 1 night stays on biz trips. Probably wouldn't have made a point of doing it if it was just to get miles in my other airline accounts, since I'm more concerned right now about maintaining airline status than getting more miles.
But for a casual traveler, this promo is probably a good way to top of an account to get a usable award ticket quicker.
