Tankering Fuel
Hopefully someone can help me out here. I am wondering how much fuel an aircraft will typically "tanker" to a destination where the fuel is more expensive?
Let's say LGW-TFS on a 757, which would take about 13-14 tonnes trip fuel. Are we talking about taking 2 or 3 tonnes extra (on top of reserves) to save a bit of cost at the other end, or more like 10 tonnes extra to land @ MLW and not have to load very much in the tanks for the return trip at all?
Obviously the price difference must come into the equation somewhere as you must burn some of that extra (tankered) fuel simply to lug it around with you?
Any expanation would satisfy my curiosity! Thanks.
