That's about the only airport that could support a hub plus WN anytime soon in the middle of the country, with a slight caveat towards STL or BNA if both had significant growth.

That said, VX is only 1-2x daily to SFO from here (and doesn't serve LAX at all), and B6 serves many destinations but isn't more than 2x daily on any of them (I don't think, but definitely not more than 3x daily). So, even here, neither is particularly large.
