I have been told by our charter sales team that extra fuel burn is almost irrelevant in our biz jet operations. The greatest proportion of cost is spent on flight time. They have told the owner that they can expect to make X amount of profit on a flight, every extra minute of flight erodes that profit far more than extra lbs of fuel.
So, as long as specific range is not a concern they want us to fly as fast as possible, even on ferry flights. Therefore we climb at 300kts, if not too heavy etc.
Don't tell the Greens
