If any of the PIC time is C-17, up to 500 hours counts towards 121 upgrade. That could be a good thing, but if your record is otherwise clean, you won’t be anywhere long enough for it to matter.

That being said, a three hour drive to DFW is just far enough to make Envoy’s reserve rules hell, especially if you do end up with an early upgrade. Also, look at where Envoy new hires have been going. 145 NY or 175 ORD. Being relatively young and not a cadet means not seeing DFW anytime soon, so that negates the DFW benefit.

Look at Mesa and Skywest. Both have DFW bases and you can choose the CRJ which makes DFW easily attainable. New hire base for Mesa and probably within two months of finishing training with SKW.
