It's a big moving target, right now it's at 5-6 years, but in 2017 it was 2 years. You can expect 18-19 days off a month as a line holder, maybe closer to 15-16 in the summer. As a reserve guy, you'll likely put on a uniform a lot less and have to hit the sim to keep landing currency. On reserve, I think I averaged 6ish days/month. QOL was amazing, especially if you live in base. My only complaint is that I hated 6+ day trips, which made up most of the bid packet. Sleep is an issue that you'll have to figure out.
