Another option would be EWR. I believe we operate all EWR-CLT flights, but I could be wrong on that. It seems like I'm in CLT all the time though from EWR.

Don't do PIT though. PIT-CLT is one of the heaviest commuted flights in the entire AA system as a lot of the USAir people stayed in PIT after the dehubbing and now either commute to CLT or PHL. I've seen those flights have well into the upper 30's, or higher, non-revs listed.
