Why stop at making pilot's pay for their endorsement training?
As this practice doesn't inspire loyalty, surely the next step is to bond pilots on top of this.
And why stop there? I'm sure there are pilots who would pay for the privilege of FO time.
While you're at it, pilot's will pay for uniforms, crew meals, car parking, and on going check and training.
So...what's wrong with making pilot's Pay for endorsement training???
