22 or 26 hours of flying doesn't really make a difference. If someone reinvented supersonic flight, and gave it a 20.000 km range, then that would be absolutely fantastibulastic! That would be about 3x the range of Concord, so I guess it will never happen. Boom claims to be working on a 40 seat plane with a long range, but I doubt there would be any economy in that.
