CLT is the most senior base, but you could easily hold it out of training or within a month or so. Reserve is running about 6 months in CLT and 2 months in TYS. Not sure about DAY, but who the hell would want to go there?

Upgrade should be dropping to 2 years or less.

PSA is pretty good to work for, but the worst part is scheduling. They are ruthless. Once you get off reserve, it is awesome, because you wont have to deal with them much.

Preferential hiring with US Airways is another plus of being at PSA.

Hope that helps.
