TYS lines are different than CLT. The majority of the trips start very early and end late. That is the major drawback to the TYS base. Expect to be deadheaded to CLT if you are on reserve to do trips. It makes no sense. They will have a CLT guy sitting on reserve doing nothing, yet deadhead a guy from TYS to do a CLT trip.

The Knoxville area is nice. If you are looking to relocate, I would choose TYS. If you are a commuter, go to CLT.
