how commercial jets vs. private jets vs. light aircraft fare
Just looked some up, they’re approximately, per passenger:
-, bus, ~100…300mpg/pp
Commercial jet, -, ~60…120mpg/pp
Ultralight, motorbike, train, ~50mpg/pp
Light aircraft, car, ~15…60mpg/pp
Private jet, limo, ~5…50mpg/pp
Fighter jet, monster truck, ~0.5mpg/pp
The more passengers, the more efficient.
So, fully loaded, there isn’t that much difference between a private jet, a limo, a car, light aircraft, ultralight, motorbike, train, or low range commercial jet.
But if it’s a single person, a private jet would use 10 times more fuel than a motorbike.
