Evidenced by the job market, it seems like QOL/work rules/company outlook/bigger aircraft seem to outweigh payscales...companies like RAH and Skywest have plenty of 121 guys willing to jump ship on their current employer, but they don't necessarily have the best pay or upgrade times. If it was only about pay, ASA and Eagle would have no trouble finding pilots. If it was only about upgrade, Pinnacle and Mesa would be sticking to their 1000 hrs TT....but the only places out there requiring 1000 hrs+ still are RAH and Skywest, I think mostly b/c of QOL and because there are several guys who illogically chase the EJet and the 900, even though it will probably delay their career progression for a number of reasons.
