Its a pax aeroplane not a business managers aeroplane. The fact is the Dash 8s or 717s will fly more passengers per aeroplane and make more money for the group then the 380s ever will.
Whilst there is some truth in that, yield management has a lot to do with how much money an aircraft makes. If it is truly a passenger's aircraft they will pay a premium. It also has premium cabins which don't exist on a Dash 8 or 717.
The Concorde would be the extreme example of all that in practice. It even had it's own lounge for one aircraft type, however the offering was so compelling that people paid the money.
