I think that for the majority of passengers on the majority of routes, current
speeds are "fast enough," in relation to the price point. Higher speed would
come at a higher cost, and most travelers don't want the higher speed badly
enough to pay the higher cost. Indeed, the market seems to indicate that
people want the lowest possible cost, and are willing to sacrifice a great
deal to get it.

Modern airline flights are slower than their predecessors, thanks to more
traffic in the air and operating procedures that favor fuel economy over
speed. The fastest airliners are also the oldest (e.g., the 747). Nobody
seems to be complaining.

True, but a tad stilted because the majority of routes wouldn't be
a consideration at all for supersonic flights. Take the routes served
basically only by 777, 767, and 747 as well as the Airbus equivalents
and although it might not be the "majority" there are some long
flights
which could be a candidate for such an aircraft. Problem really is
I suspect that there aren't enough of them to justify the development
of the aircraft.

But I do know that people resist trips once the time required goes
beyond about 10 hours. Being able to cut these times down,
and on even shorter routes being able to make multiple trips in
a day would seem like a useful capablity. It's just the same old
thing about there being enough of a market to justify developing
the plane. These things are expensive to engineer and produce
and take the better part of a decade or two to realize any
net profit.
