Pilotchute,
I think you should get a job in the revenue management department.
Reading your post I got a great idea.
Why not sell the business and first class seats really cheaply, that why you fill them up no problem and by your logic all will be well as the price you sell them at does not seem to be a consideration.
Take it to the next level, buy a couple of A380s and just put first class seats in them ....... we'll be swimming in it soon ........
Heard of yield before ?
