That has not been my experience. They have left the gate with non-revs and empty seats in First. I have to see what happens on my trip to PVG next month. It's not like I'm looking for an (undeserved) upgrade as I have my preferred Business seat and if I had wanted to fly in First the price when I booked my flight was very cheap.
