Airliners are pretty darn fuel-efficient, more efficient than even many lightweight cars. (Assuming you don't leave seats empty, that is.)
As of 2017 [1]: "Domestic airliner can get anywhere from 45.5 to 77.6 miles per gallon per passenger, with an industry average of about 51 miles per gallon of fuel per passenger."
For comparison, the average car gets something like 25-30 MPG, so airliners are some 2x more efficient.

- pyrale 5y agoThe average car also comes with 4 seats, which theoretically puts them below an airliner. But my joke was about the plane fuel use, not per-passenger.
- hetspookjee 5y agoWhat average car are you talking about ? 9.5l / 100km is attrocious and average in 2005. A starlet from 1998 gets better fuel economy already. And so does a Volvo v40 2.0 turbo. I believe a 1800kg modern day M3 sports car already gets better fuel economy than a plane if you seat it with 3 people.

- hetspookjee 5y agoI couldn’t find a detailed breakdown in one of the sources, but how can the average be so close with light trucks and vans. In any case this is not representative for the majority of Europe.
