ATL-JAX is supposed to be an OK commute. Skywest and Endeavor both have bases there. at Skywest, once you can hold a line, you can plan on 90+hrs with 11-13 days a month off whether or not you want to fly that much.(an FO line is 8-10 months from hire date) ATL at Endeavor used to be very stagnant, I'll let one of those guys chime in if that's still the case.
