Perhaps, however do understand that large corporate sub sonic planes provide sleeping arrangements sufficient to allow a fairly painless trip. Super sonic then becomes a choice only when speed is mandatory and that then begs the problem of jet lag which delivers you seriously maladjusted.
That is why there is no compelling demand profile ready to support a Concorde like solution.
The only thing that changes that will be rocketing into low orbit and then dropping down to the destination. The problem with that is the deceleration process along with g forces. Give it up already guys.
Wait until we develop wormholes big enough to easily pass through while controlling time and acceleration variation. These can be set up as locked routes for volume traffic. Likely will not solve jet lag though.
Supersonic travel is on the verge of a comeback—here’s why
As a plane accelerates, it builds up a front of air pressure by pushing air in front of it. When it passes the speed of sound, the pressure trails behind like a boat’s wake, forming a sonic shock wave. [Photo: Chabacano/Wiki Commons]

These engines also greatly reduce airport noise by accelerating a larger volume of air to a lower velocity than smaller engines. The new engines are so quiet that regulators have twice been able to decrease the amount of noise airplanes are allowed to make since Concorde stopped flying.

This is the approach being taken by Aerion.
