I wonder what the breakdown was for leisure vs. business travel on Concorde? My gut tells me most of the Concorde passengers were flying for business and the way things have changes in terms of business travel I'm not sure that market is there anymore.
edit: that was easier to find then I thought it would be "Before service resumed in November, both airlines had kept in contact with frequent Concorde fliers, 80 percent of whom are business travelers..."
