Something I never learned to do was get the boss used to the big bills like others have. A few nightmare over hauls and inspections, these guys start looking at bigger planes.
Seems I went the other way, roundly beating the NBAA numbers, discounted fuel, deli sandwiches from down the block, landing at airports where the fuel was a buck less then big FBOs. Everyone is tickled, no reason to buy a bigger plane...why should they...packing all seats in a Citation, beating the airlines at their own game.
So you got kids that screw it all up, can't manage to buy a box of peanuts right, getting types in GIVs and Galaxys, where some of the old salts are stuck in Turprops and little jets because the boss is just so happy that we make the little planes ultra efficient.
