Totally agree. Lots of people will tell you that you fly less as you get paid more. In my experience that's totally untrue. This would also mean that there was some kind of plan or organisation in your roster. There isn't. Rostering don't have the time or the inclination, they're just firefighting most of the time.
There are no guarantees - much depends on your base but even then you can expect plenty of out of base time to make up the hours. You can expect to fly a fair number of hours when all is said and done. From what people tell me, the average is 700-750 per year in your logbook (ie you are usually paid for more than that).
