Drop mil leave and go get paid dude. Eff the airline decoder ring BS. This thing can take a turn for the worst again with the next economic downturn, making these "can you hack it?" moralizing arguments about quitting regionals "too soon" a moot point.
According to the peanut gallery, you'd only need 12 months at the JV shop and you'd be in mainline Shangri-La as a current prior mil-jet dude, but when it doesn't happen it's now all on you for not having had the foresight and plan financially for a proverbial 7 year wait at the FFD job you never wanted in the first place. Meh. Never put in the middle what you can't afford to lose. If that means the loss of a hypothetical 5 years at WB CA rate in your cosmic radiation induced cancer-ridden sixties, so be it.
In the words of Ray Liotta: FUPM. Go get paid dude. Your family's time is a more perishable commodity.
