For long-haul, it's cruise. And the energy required can thus be improved directly proportional to lift to drag ratio. What I find promising is work NASA is doing and has done on truss-braced wings to enable a ~doubling of current transonic lift to drag ratios by using an extremely high aspect ratio wing.
