First year is usually a little light on the hours just because of reserve and a 3-4 month training cycle. Second year on you can plan on between 700-1000 hours a year depending on reserve time and how much you want to work. 1000 hours is the maximum allowed during a year for 121 operators. There are a few exceptions, like Great Lakes, I believe those guys can fly 1200 hours a year. It's kinda funny though, once you've been around a year or so it become more about how can I fly the least and make the most
