One of the best and most memorable experiences I've had was sleeping in Premium Economy on the upper deck of a BA A380 back from San Francisco (from a work trip). It's quiet and the ride quality comfortable. It's a shame the food on that trip didn't make up for it. The A380 is one of my favourite aircraft. I never flew on a 747 and likely never will now, so it's the next best thing I've got for a two-deck experience.
