A plane like a Boeing 747 uses approximately 1 gallon of fuel (about 4 liters) every second. Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters). According to Boeing's Web site, the 747 burns approximately 5 gallons of fuel per mile (12 liters per kilometer). This sounds like a tremendously poor miles-per-gallon rating! But consider that a 747 can carry as many as 568 people.
An average flight on an American Airlines 737-800 costs $5308 per hour. The plane burns 850 gallons per hour. Fuel costs $4,156 based on Jet-A fuel costing $4.89 a gallon. A cockpit crew of two along with five flight attendants costs around $465 an hour.he Airbus A380, the largest passenger jet, costs between $26,000 and $29,000 per hour, using roughly $17,467 of fuel, approximately $40.19 to $44.82 per mile.
