Yeah, doesn't seem very to have any correlation with "Frontier," at least not on the surface.
By the way, smooth and excellent first time experience on Frontier. I opted not to pay for the seat assignment and was assigned a window seat based on my profile preference.
For the value, Frontier can't be beat, in my view.
