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.

A fully loaded bus, still wins hands down.
