I'm surprised by this... I'd imagine that all of the BS we've added to airport procedures (under the guises of "security", mostly), would sort of help negate the typical "Concorde" case. In a universe where you still need to show up umpteen hours early for check-in, baggage, security, does having a plane that may cut a fraction of the time of the trip really seem compelling?
Getting from curb-to-gate today is easier and faster than it was pre-9/11.
That's just domestic. For international travel it has been a literal exponential decrease in hassle.
Of course, this all depends on whether or not the airport you use (and it is 100% dependent on the airport itself) has deployed all of the automated systems being used to lower terminal transit times.
THAT would make tons of sense to me... here the flight is a greater share of the overall flight time, so cutting into that yields a greater percentage reduction on overall travel time, which is presumably the variable you'd want to most affect.
