Same here, except in my case it was the only reason I ever would fly them!!! As presently configured, they had better seats than most other carriers if I couldn't reserve an exit row (or premium economy) seat on another carrier. That was the only reason for me to consider Frontier, given that I'm a miles collector (and their miles have too few partnerships to be that useful to me) and I'm not based in Denver.

I guess I'll figure out how to top off my Frontier miles to an award, redeem once on a no-longer-comfortable plane, and then forget they existed (dump the credit card, cancel my Frontier account so they no longer send me the useless emails which tell me nothing more than to check their website for my account update, etc).
