My question to you is:
-1 If given a job worth millions, do you turn that down? (guessing you are at an LCC place that has that in your contact about dropping to zero - but honestly who does that?). We at UAL cam take an “EMPTY LINE” when available and that allows you to start with ZERO pay credit, and pick up trips when you feel fit, and after 1300 Local Base Time, you can call and pick up trips out of your domicile. BUT THAT IS HARD TO COME BY NOW DAYS, with all this expansion planned.
-2 do you really want to fly airplanes for a living?
-3 do you actually have a job offer or just an interview? ( Because, just an interview - I’d watch everything said and posted)

Otherwise, with the growth plans: I’d expect everyone hired today will spend very little time on reserve (Coast Bases Only). But from personal experience on Reserve you can drop a day or two ( but you lose 4.03 credit each day). If you have money or another partner making BANK) then it’s more important to drop year 1. But if you can drop to ZERO, I’d highly doubt it in today’s UAL environment…
