Fair point, though with the exception of Jet Blue I feel as though you just described domestic air travel in general.
Edit - so crazy but minutes after I posted this I see a note on my Spirit app (I'm waiting to board) saying Spirit and Jetblue are merging. Which makes me sad because I like both of them separately. I have a feeling this is going to bring on the wrong kind of changes, where Jetblue starts playing the nickel and dime game, eg charging for a printed boarding pass, while getting rid of the best Spirit a la carte perks, like the big front seat, to make way for traditional first class. And I would imagine they retire the aging, roomier Spirit fleet so they can deliver the tighter, yet fully wired, experience Jetblue is famous (infamous?) for.
