Economies of scale generally favor larger machines. It would take more fuel to carry the same payload as the 747 using a fleet of Cherokees.

He meant just the fuel a 747 burns in an hour weighs as much as 10 complete Piper Cherokees 
Quite impressive.
But it is just 8 gallon per passenger per hour, or thereabouts. Say 70 mpg per passenger.
About the same as the Cherokee, I guess.
A loaded Greyhound bus beats anything smaller with an ICE on mpgpp.
Trains might do better though.
