I believe that every private jet owner cares about costs. Who wouldn't? Just because one has a jet all to himself doesn't mean he wants to do away with all his money for silly requirements.
While choosing your operator it is imperative that certain rules are laid down. Telling them of the drawbacks of your earlier operator (if you had one or if you have been told of by your friends/colleagues). Nobody wants to give away their money for something that doesn't even make sense. I mean come on, to throw away trash? or a box of tissues for 80 USD? What do they think private jet owners eat? Gold bars?
