I realize this is a simple question, but I want to make sure I'm 100% clear on the answer. I just switched my HHonors account to earn base points plus variable miles (tied to US Airways for their upcoming Grand Slam promo). My question is, what dollars per stay are elligible point-earning dollars, and which dollars are not eligible to earn points? For example, I have a one night stay coming up at $199/night. With local/state taxes, the night will probably be around $230. But will I only get 199 miles for that stay? I'm guessing you probably don't earn miles on tax dollars, but I'm not sure. What about in room purchases? For those not familiar with the US Airways Grand Slam promo, you need to earn at least 200 miles per stay in order for the stay to count as a "hit" in the promo. So in my example above, will I miss out? Can I order room service to get extra mile-eligible spend? Or is room service/movies/minibar etc not eligible either? Thanks for any enlightenment here!
