They've definetly come up with a unique program. I skimmed through it and didn't notice what most of us consider the most important part of a FF program: Upgrades!

I flew them once on a cheapo to NAS a couple of years ago, wasn't too bad. Their SpritPlus business class (on the MD80 that I flew) is more comfortable than NW's DC9 or A319/320. Now that they're rapidly transitioning to an all new all Airbus fleet, I'm sure that the comfort and reliability factor will continue to improve.

It was interesting seeing the topic of this thread as 10 minutes before I helped a friend book 3 DTW-LGA r/t's on Spirit. They were about the same price as NW, but this is another $650 that NW won't get because of the RoachChoice program.
