I'm not holding my breath for any of these supersonic jet projects to come to market. But, if they do, I expect the nominally "business" or "first" class seating will be more like domestic business today than typical international business class--as was the case with the Concorde.
That’s Boom’s business plan explicitly. Cut down the flight time to a couple of hours and you don’t need to offer a bed, making the per seat cost comparable.
