The 67mpg figure IS ALREADY PER PASSENGER! Do you truly believe a plane full of passengers only burns 15 gallons to travel 1000 miles? Why does a 777 need to carry 13 000 gallons of fuel then? By that logic that would be enough to travel 1 066 000 miles considering they get 82mpg/passenger when full of passengers (which you interpret as 82mpg/vehicle)!

Napkin math time:

6000 to 7500 kilograms of fuel per hour for a 777, gas weights 0.72kg/L, that's 8300L of fuel burned per hour and I'm using the most advantageous number to help you! Typical cruise speed is 900km/h. That's 108m for every liter of fuel, 410m per gallon, 0.25 miles per gallon. Hey, look at that, pretty fucking close to the 0.21mpg with a single passenger that I calculated with the official number, isn't it?
