Nice report mate -- had seen your video on youtube -- now I know who you are!
I've decided to give them a go -- flying LAX-DXB-VIE in a couple of months -- should be able to get some decent shut-eye over the 16 hour flight.
Finally burning some QF points -- think the 192,000 is quite reasonable for 2 x A380 long and medium hauls.
Will post some pix and a report here when done.
Thanks again!
