K Thanks for that explanation of the basics.
So, if applying to regionals, can one choose which base to apply to? Relocation is not an option and commuting seems to be untenable. I live near EWR, but <2 hrs to LGA/JFK/PHL

Crazily, my goal is to fly as much as possible, and I have plenty flexibility on schedule with stable home life and grown kids.... Can one get more flights while on reserve?
I'd like to hit 1000 hrs / annum cap
