Took the A380 for the first time last month on Thai in F.

I was absolutely blown away by how quiet the plane was, and noises from other passengers weren't a problem (obviously given how sparse the seats were.) The air circulation was also definitely better than any other plane I've been on. It was only a 5.5 hour flight, so no chance to have a real sleep - but I know that noise definitely prevented me from sleeping on my ANA F flight.

Only thing is now once you step on any other plane, you feel the noise even more. I personally went out of my way to book my April trip on the SQ and QF A380s. Spent more miles, but more than happy to if I don't have to feel like I'm sitting next to a vacuum cleaner.
