Yes it does.

Seems like a lot doesn't it?

But, we must consider scale.

A 747-400 carries around 63,500 gallons of fuel, which actually makes that gallon-per-second burn rate quite efficient when you think about it.

At cruising altitude (around 35,000 feet), a 747 burns approximately 5-5.5 gallons per mile.

Works out to about 0.2 miles per gallon, which sounds terrible until you consider that the plane is moving nearly 400 people and their luggage at about 550 miles per hour.

Break it down per passenger, and you're looking at roughly 85-100 passenger miles per gallon. //

Greyhound many years ago measured its bus transport efficiency in passenger-miles/gallon. Their goal was to …wait for it… get to and maintain that very 85–100 passenger-miles/gallon number range.
