A fully laden Boeing 777-300ER cruising at 35,000 feet burns approximately 7,500 kg (2,450 gallons) of Jet-A fuel per hour, working out to roughly 1 gallon of fuel consumed every second. However, carrying 350 passengers, its efficiency translates to over 80 passenger-miles per gallon, making it more fuel-efficient per person than a single-occupant passenger car.
