That's an average salary. The way I understand it (and I may be WAY off) is that at AirNet, you are paid an hourly rate for your flight time, and another rate for your ground time....or you get a base salary that's contingent on your flying time, plus overtime if you get any.
If you - for instance - get a route where you only fly four hours a night (AirNet has a couple) with four hours on the ground in between runs... you're making squat.
Some AirNet pilots who were hired in my former instructors class are making some GREAT bank for first year pilots. Others, like him - are barely getting by. He actually thought about leaving and going back into the Telecom biz... that's how bad it was.
He's about to bid out to a busier run though.
At the FBO where he instructed, it was VERY busy, plus he flew with private owners on the side. He was doing pretty well comparatively.
