The "as long as they could keep most seats filled" was a deal killer though.

There was enough demand for one return flight a day carrying a small proportion of the overall passengers on the immensely-popular with wealthy people JFK-LHR and JFK-CDG routes.

They both also used it for private charters which was apparently quite a profitable business. Anyway, the exclusivity was presumably more profitable than simply maximizing occupancy.

That said, boom is building a significantly smaller aircraft which should again open up more possible routes.
