I am not so sure. The problem is that you probably would have to rearrange the entire airline industry. You could for instance just run long haul flights from a few places per continent. Then you could engineer an airplane model to just go back and forth in comfort between two places in the middle of nowhere and optimize the hell out of everything. Today everything is so "unorganized" that airline can't even offer a good experience on the ground, which would be the far easiest innovation you could make.
