Most of the posts that declare a preference for traveling on the A380, seem to be from “Premium SLF”
My one and only sector on one was a SQ flight from London to Singapore, in the back of the bus. It was the most uncomfortable long-haul flight I have ever experienced. Both my wife and I made frequent trips to the lavatories, not because of a need, but just to be able to sit in a different position for a few minutes!
My only other encounter with an A380 was an hour in a simulator. That was a completely different experience.
