The airplanes this is about mostly are relatively fuel efficient. They burn a lot of gas per hour, but they also go faster than a car and so per distance efficiency is about the same as a gas car.

Jets are different - they go a lot faster. Commercial jets when full are about the same as a small car. Private jets generally have much less people on board, if you filled them to capacity with people they do well.

A cessna 172 burns 8 gallons an hour in cruise at 125 mph. A generic sedan at 30mpg burns 2 gallons an hour at 60mph on the highway.

The calculations do not work for small planes. The energy to go double the speed is not double the energy.

But they might use a 15mpg SUV instead.
