Bullish on Frontier?

Is anyone else very bullish on Frontier? Correct me if I’m wrong but frontier and spirit are basically the only major budget airlines, at least in the US. JetBlue I wouldn’t say counts because it really isn’t cheaper than other major airlines.

I feel like this thing should just keep flying up and having huge Green Days, I get fuel is still high but in my mind all of spirits business and a lot of their routes are going to frontier.

Is this accurate? How bullish are you on Frontier.
