I don't think commuting from CLT-DC would be miserable, it would likely be pretty reasonable. 6-9 daily flights to IAD, 8-13 flights a day to BWI, 9-16 flights a day to DCA with the pretty easy metro connections to BWI and IAD. CLT to ATL has 15-21 flights a day, so you're looking at about the same in my book. Commuting sucks for sure, but that looks like a pretty good situation to be in if one had to commute. 6 hour drive to DC vs 4 to ATL (although needing to drive through ATL could take 2 hour. If it takes 6+ months to get captain, and you get a year of PSC, they only have 8.5 years from there. If it got bad take WB FO and cut the number of commutes drastically.
