Thanks for transferring that info. I actually saw it in a different thread too, however where that thread is now, I have no idea.
I guess that comes to whether or not those days are paid when you are on call, or only the days you fly. If you are on call for 20 days a month and only fly 12 of them... would make it difficult to budget your expected income.. also if demand for charter drops off and start flying less, it would be a pretty large pay hit.
