Any idea how much a litre of Jet A-1 costs?
When you have the average Fuel/km (mileage) then you have the info that he is really looking for.
How much fuel (litres) do you burn from A to B and how much it costs and the efficiency of airplanes. Why does my Ticket cost so much? etc. These were asked once when I was an F/o and the Capt came up with some weird answer. Can't remember the cost. It was a long time ago. Besides, fuel prices have gone up!
Looking for more information. Nice Topic.
