It was the only plane with an upstairs. I never got to go upstairs. :(
Always loved flying a380s
I used upstairs a lot. It was nice. Side bins, and quieter.
Upstairs on a 380 is different. The nearest comparator is the Emirates lounge bar up the back.
Also, glass windscreens are a liability - I imagine damage caused by FOD impact kicked-up on the runway during takeoff to a glass nose would be far more expensive than whatever material they use today is.
