One way Concorde JFK/CDG fare is USD 4000. Multiply that by 100 seats. Fuel about 200,000 lbs, or 29,850 USG @ USD .85/USG?
Then add engine reserves/maintenance and crew costs, ...USD 10,000/hr and you'll get an approximate figure. (3.5 hour flight). So with one roundtrip in one day a full airplane can generate over $600,000.
Prior to the crash BA had claimed that 20% of its overall profits had come from Concorde.
You don't need an abacus to know that Concorde is a moneymaker.
