Was the "mileage" of 747s (?) discussed in this group today?

Not to my knowledge but I've seen several posts elsewhere today about fuel
efficiency.

They
drink a lot of fuel too, though not too bad when you consider
moving 400 people the same distance by other means.

It's not a 747 but Airbus claim their average is 3 litres per 100 passenger km. (
about 100 UK mpg or ~ 80 US mpg )
