Oh, really? And how devalued is your product if nobody buys it? It brings you zero revenue. Tilton&Co devalued their product more than a free upgrade ever could through its nickle and diming and ....ing over its best customers.

Plus what do you care if someone takes an empty business class seat? It's big enough that you're not affected.

There's a reason I paid over 40% more to fly with Asiana over United when I went to Asia this May. It's because they treat me like a highly valued customer, even if I'm just a lowly Silver member who rarely ever flies with Asiana. I think I was treated better with Asiana as a lowly Asiana club silver than some of you 1k and whatever else were ever treated by United. And that's why I'll try to fly with Asiana if I ever need to go to Asia.

Meaning: if, as a business, you treat your customers right, they'll come back. I'm sure you'll agree that someone who was treated well by a business is much, much more likely to come back and pay to use its product than someone who left completely dissatisfied. Meaning: treat your customers like royalty, and they'll come back to you.
