Depends. In general I would say you are right, but that leaves out the business traveler of today. Concorde was to far ahead of its time and then got 100% screwed on bad luck with the Oil crisis in the 70s. I have done 50K miles so far this year between CA and APAC. The flight is 12+ hours most times. Give me something that is +25-40% $ on a business class ticket today that take the flight time to 3 hours and I will buy it. I think that to be true even for the economy tickets for the long haul flights. I think people in the back of the plan would pay lets say $1200 for that flight to Tokyo over the current $900 for the flight time to be cut by 8-9 hours.
