If getting a seniority number at an airline is the goal given that situation, I am of the opinion that getting out and slumming it as a CFI/regional pilot is a better bet than taking another three year ADSC. I also don't think that AFPC is going to find a glut of drone guys so desperate for some flying hours that they take orders hoping the next three years will be different from the last ten. Maybe I'm wrong.
Regarding your other question, I plan on picking up a deployment gig after I get out. I'll end up being gone six months out of the year, which isn't any different than what I'm doing now. I'll spend the other six month a year building time. That's my get well plan at least. The contractors aren't going away because the AF can't retain people. And if all that falls through, I think the McDonald's around the corner is hiring so I have options.
