Source conflict: AirlineGeeks also lists an Austin–Knoxville (TYS) route, citing Austin’s airport. The Points Guy, Upgraded Points and Airways do not include it, so it is left out of the table until Southwest confirms it. Southwest is also bringing back summer seasonal flights from Nashville to Bozeman and from San Diego to Bozeman, Pittsburgh and Columbus.
