> Even against the most modern aircraft the A380's fuel consumption per pax per unit distance is likely to be competitive Just a few weeks ago here on hn there was a discussion about this. Someone claimed the reasons A380 has poorer fuel economy per pax than A350 or B787 are - older design with less usage of lightweight composites. - older engine design. - wing design constrained by need to fit within 80m box (size of airport gate apparently). - wing design optimized for a lengthened variant (that was never realised).
