Those are also a lot of the people that do the interviews. I think it's pretty darn awesome.
And in regards to Frontier's pay, let's not forget that those legacy carriers have left a large chunk of their pilots furloughed off and on over the past 15 years. This is just me personally, but I'd much rather prefer the steady job and the pilot group that goes out of their way to keep me.
