It's funny, but does anyone here besides me have a clue as to thier per gallon cost of fuel at the departure or destination point inorder to determine how much fuel to tanker here or there to figure this out..?? If you don't then it's all moot, you simply carry as little as possible to make the plane climb and fly faster, fly as high as you can to get your fuel consumption as low as possible per trip, go with long range power settings...as airliners can go 20000 hours on an engine....unlike corporate... For corporate there is a point where the engine cost out weighs the fuel cost(not lately)...so in the past we went fast, now we go slower, and really shop fuel....
