LoL, works for me.
We could maybe issue a slide rule with a 777 to 380, passenger/cargo/fuel converter so the Trip boys can see how much extra they are contributing to the profit share due to the fuel they are saving! The scale could be attached to a ring tone on the company phone that gives a hearty bugle call for each ton saved so the shorter the trip the more triumphant they would feel. Maybe even issue a new bag with a special slide rule pocket, note to AS.
