I agree that it is highly seductive to allow myself be tortured, OK not tortured but greatly inconvenienced, to save $200/hr. But I would not imagine that the airline was paying me that money. Else, I should just imagine that I could just stay home and get the airline to pay me the cost of the whole ticket.
Anyway, before I made the earlier post I made a sample price check. A round-trip coach seat to SYD was around $2K, a business seat was $8K, and a 1st class $21K on Qantas. Does anybody really pay for these 1st seats and not get it via upgrade? It's mind boggling how much money truly rich people have.
PS. By the way, on a long flight like that, a business seat allowed me to lean way back and go to sleep through most of the flight, waking up only for meals (3 of them!), and the flight felt so short. I have also flown business class to a Middle East country for work, and the experience was also positive. We have flown to Europe on business class, but as the flight leg was shorter the difference in comfort between coach and business was not as pronounced as the super long flights.
