Do I need to book from United.com to earn my 50 miles per day for UA from Budget? Or can I book from Budget.com or a third party? It would be nice to book through ultimate rewards and get 3x points and the extra 50 miles per day on top of it.

I would say yes since its their promo.

Yeah probably huh. Man, now I have to do some math to see what's the better deal. Simple, but still...

thanks for the codes guys, please be sure to post in the upgrades thread i started after your rentals. its a big help in some of the other rental companies sections so I am trying to get it to catch on here.
