Ahhh but Glueball, you put those same 100 people in superpremium first class in a 747 and you make even more money. However, with those people off the 747 the yeild on the subsonic fleet falls.
So yes the concorde can be profitable if looked in and of itself, however, it is a yeild killer on the rest of the fleet operating the route.
That may be why BA is making money now inspite of the downturn. It will be interesting to see BA's overall profits once the concorde is reinstated.
