777 burns 9366$ of fuel per hour. The costs were calculated with $4.55
per gallon. So, how many gallons or liters does a Boeing 777 burn per
2058.5 gallons or 2058.5*3.7854
7,792.2459 rounded up 7792.2 liter per hour.
Those were old figures and from the US.
Lets do an update and use figures from Britain.
Fuel prices in London:
A ticket from London to Madrid and back for about 100£
Actually I did the calculation already here:
The ticket would cover 66% of the fuel costs but can't be more than 40%.
So where does the airline get the extra cash?
