Just thought I'd share an experience - I upgraded Mrs. Redtop to PV on her flight earlier this week (DL award ticket, got an email offering PV for €139 or Affaires for €329) and she just wrote and said:

"The seat was a business class seat, it was reclining all the way down into a bed, the food was business class like with real silverware and my luggage was prioritised (it was nice to not have to wait for it) . It was worth every single penny, it was really awesome. I looked at the other business class seats and they were the same, slightly different than the first class but really what you got was everything I needed, all the comfort possble in a commercial flight."

So I wonder where she really sat - not that I'm arguing! (Was AF023 JFK-CDG.)
