I had a great FA come around recently (to all the Golds in Y, of which there were only a few) and show us to entirely empty blocks of 4 seats on the 380 - just before pushback when all pax were being told over the PA to sit in their allocated seats for takeoff.

After takeoff, a small bag with eyeshades, toothbrush and playing cards was delivered with a smile.

It was a better night's sleep than I've had in 'sleeperettes'...
