It will take 2,641 gallons (10,000 liters) for a short-haul domestic flight, or up to 18,492 gallons (70,000 liters) for a long-haul intercontinental flight (for example, Stockholm to New York).

Let's take a look at how much Jet A a widebody aircraft actually uses as it traverses the skies.
"That means that during a five-hour flight, a Boeing 747 will burn 18,000 gallons of fuel."
metmike: Let's say the average person has a car that has a tank which holds 15 gallons of gas and they use that much each week.
Divided into 18,000 gallons gives us 1,200 weeks worth of fuel, which is 15 years of fuel for the average car used by a 747 jet during a 5 hour trip.
Granted, there will be 400+ people on the trip and it goes many thousands of miles and it saves many thousands of hours of time compared to driving and in fact, makes trips across oceans and elsewhere possible.
But let’s say Harrison Ford gets in his private jet and flies from California to Florida for dinner, how wasteful is that? Oh….and the dinner is talk about climate change.
Yes, it's when they use PRIVATE jets to travel that causes the massive, wasteful fuel gobbling that takes place.
