As has already been said. For DAY or CVG it's a 2 leg commute once you can hold CLT it's a 1 leg commute for a year+ on reserve.

I would look at compass first. SEA base and currently 6-8 month upgrade with prior 121

I'm more curious why you would even consider PSA? There are several airlines with much better pay and contracts that would be a much much easier commute.
