true, no HHilton on NWA or America West, and not on US AIR either.

BUT at least with NWA you can get tickets that sometimes require 10k plus money. I have seen many a deal where it's like $100+ to fly within a zone plus 10k miles. I think it said the person has over 6k so a few decent group dinners and you have 10k sitting there waiting.

America west: I dont know. Stopped using them after my 3rd bad experience. I wrote to CO hoping they would drop them as a partner and they did. I know it was not me, but I always like to think it was my letter that got them to do it!
