That said if they're on time and you can get a nonstop on the route you want for cheap it works. It's just not going to be a comfortable flight.
FWIW, they will give you free water if you ask.
But I agree -- if you know how to play it (basically, try never to pay for bags), Frontier can be a good value. But it is rarely a good experience, and almost nobody would say they "enjoy" flying Frontier. For that reason, I don't like their long term business prospects.
