On a per-passenger basis, a Boeing 747 is significantly more fuel-efficient than a typical car. A 747 burns about 5 gallons of fuel per mile, which sounds abysmal. However, when carrying 500 passengers, that works out to 100 miles per gallon (MPG) per person. In contrast, a typical car getting 25 MPG with only one person (the driver) is four times less efficient. Even with two passengers (50 MPG combined), the car still falls short of the jet's efficiency at cruising altitude. In 2026, newer aircraft like the Airbus A380 or Boeing 787 are even more efficient, achieving up to 120 MPG per person. While flying has a much higher total carbon footprint due to the sheer distance traveled, for a long-distance trip from NYC to LA, flying uses about 27 gallons of fuel per person, whereas driving the same distance alone would use over 110 gallons.
