Aircraft are thirsty and burn lots of fuel, right?

Similar or a bit better per mile to an efficient European ICE car with a single passenger. But:

- you travel vastly more miles in the plane

- you could fit four people in the car to achieve quarter the per person fuel consumption

Also assumes you're riding in economy.

Electric cars use around quarter the energy per mile than ICE, so therefore beat the plane easily even with single occupancy

    https://en.wikipedia.org/wiki/Fuel_economy_in_aircraft gives some numbers:

    > For a comparison with ground transportation - much slower and with shorter range than air travel - a Volvo bus 9700 averages 0.41 L/100 km (570 mpg‑US) per seat for 63 seats.[113] In highway travel an average auto has the potential for 1.61 L/100 km (146 mpg‑US)[114] per seat (assuming 4 seats) and for a 5-seat 2014 Toyota Prius, 0.98 L/100 km (240 mpg‑US).

    and a Airbus A320neo has a fuel efficiency per seat of 1.94 L/100 km (121 mpg‑US)

    It all depends on the load factor.

Now do the same calculation for private jets.

And for high-speed trains.

TLDR: No if you decide to compare them to cars for some reason
