Thanks for all the suggestions. I had decided to not nest my trips (maybe I'm just chicken but I don't want to risk my PremEx status). I was going to use Comicwoman's good suggestion, but then I got invited to a Nascar race in Las Vegas. So, now I'm going to go from Spokane to Albany via Las Vegas. Price isn't cheaper, but who cares! For my other trip in March, I'll use Jon's suggestion and go to Hartford ($626) and drive the 90 miles.
Thanks
