> 50$ seems crazy as supersonic flight is going to use far more fuel, but it also means the aircraft, pilot, and flight attendants can make more trips. So, a minimal cost increase might be possible.
This is the premise of SpaceX's BFS. Though each flight will be more expensive than a 747, they can fly another BFS each hour.
