“Could” but “won’t.”
Until the sonic boom problem is mitigated, this is just science fiction.
Plus, the Concorde established that...
1. Government regulators hate supersonic.
2. Passengers will pay a little more for a faster flight but not a lot more.
The high expense account and high net worth slice of the market tend to be indifferent to extra cost. With dedicated, de luxe passenger gates and express screening, the travel experience will be an order above that of even the best conventional airline travel. As with the Concorde, it will be fully booked.
