So again, does anybody out there operating two or more airplanes have any policies in place to add compensation when a pilot becomes qual'd on another plane?
In your case, if the aircraft are all about the same category salary-wise than you need to be paid according to how much you work. Its that simple. Now you can do what you want and ask for more money by yourself, but in my opinion that is not the way to do it. If they say no then you will let everyone else know that they said no and it will end there. If all of you say the extra flying warrants more money, you will all be more likely to get it and noone will look like the greedy pilot. Everyone that has more work to do should ask for more money. Every other occupation on earth works like that, and so does aviation. If an airline pilot was asked to move from the 757 to the 747, he would get more money. If an airline pilot was asked to fly a bid line that has more hours, they get more money. If an airline pilot is asked to fly a bid line that has him away from home more that month, he gets more money. And so on and so on...............
By the way, do you have a contract of any kind?
