I am also interested in fuel consumption per seat. As some of the previous posts have said it is important to quote like with like. I would suggest a metric of square metres of floor available floor area. It would also be necessary to convert hold space to an equivalent of this. For example a 77W has less space for passengers than a 774 but more hold space (obviously not relevant if there is not much freight around or ultra long range routes). Would it be possible to produce a graph of fuel consumption per m^2 of floor space by range. Has anyone got a link of anything is available on the web? (GH has said that published weight data is suspect - finding accurate fuel consumption data is even harder.)
