So JFK LAX JFK is about 10 hrs at 1,500 kg/hr = 15,000 kg = 19,100 Lts at about $1.50/Lt = $28,662 for fuel.
So how come it costs him $230,000 for a round trip???????????
Fuel probably represents up to 50% of his operating costs so I'd expect the total trip cost to be around $60,000.
Someone is exagerating their situation a little bit.
