We had someone skillbridge to a local flight school and racked up a crazy amount of hours in 6 months. Went right to a major after. It isn’t the most bizarre path.

A is the dream, but I’ve heard you do not want a break in service whatsoever. Maybe try to find a guard/reserve unit that’s flexible with your indoc/sims/OE schedule versus joining a unit after you’re established at an airline.

I’d go with C over B. I think we will see regional touch and goes coming back, maybe not for good, but at least until airplane deliveries normalize. It would diversify your resume with 121 experience and show that you can hack a 121 training program.
