Does Southwest fly out of NV anywhere?
Check flights into Nashville (BNA) AND Knoxville (TYS)...a lot of times, flights to Knoxville are more expensive, even though it's only 180ish miles from Nashville. If you did fly into Nashville, you could ride with a few different people into CC, depending on passenger situations. I won't speak for everyone, but we plan on having just the 2 of us in my truck, so I'd have space to ride, so long as scheduling keeps where it is. That's too far out with my work schedule to know if it will change or not.
