Welcome aboard!
The first year is going to be a slog unless you pick a very junior base. Junior reserves get worked but the pain stops at 85 hours. That's 16 days of minimum credit trips so try to get some that are higher credit (just need 1 hour cumulative, but that is harder than it sounds) then it will only be 15. Try to get some OG (extra flying on a day off) if you want but it's rarely offered and usually goes senior unless it's 0330 in the morning. Plan on 80 hours of regular pay plus about 10% for overrides, reassignments, etc. Anything more than that would be unexpected.
I finally started getting a tiny bit of OG just as I was senior enough to get a line (senior airplane, senior base). Once you get a line in a large bid status you will be able to trade and pick up and do all sorts of things. Plan on 95 hours in the slow months and 120 in the heavy months once you get a line but then IMAX will eventually get you.
Senior pilots drop all their trips and snag broken trips with high credit/low block. That's when you can really hustle but that will be a while unless you pick a junior base. Strategic use of vacation and sick time can result in 140+ months but you probably need 70% seniority to make it feasible.
For everyone reading this don't come here without a plan to live on 80 hours per month the first year and probably most of the second and you won't be stressed or disappointed. If you pick the 73 in a junior base you can probably do better than that. Pick the 320 in CLT or DFW and it's going to be a long slog.
