I was fortunate this week to fly on the new double-decker massive A380 with Singapore Airlines to and from Singapore.   So what is it like.  Well yes it is massive but also intimate.   You do not feel as though you are flying on a 400+ seat aircraft. 

Firstly it is quiet, by far the the quietest plane I have flown on and I think airbus are quieter than boeing anyway.     It is comfortable to be on the plane and you can easily to have a conversation.  It is much quieter than a boing 767 or 777 and the back ground noise is a mild distraction.

The layout  of the SQ jet is lower deck suites plus economy with economy divided into 3 separate cabins.   The upper deck is business plus one smaller economy cabin.  The separate cabins makes it feel like you are not a huge plane and adds to the level of service.  The plane feels and smells new.

Ecomomy is not too bad  with better seats and a excellent screen on the back of the seat in front of you close to 20 cm wide.   The quality of the in flight entertainment on Singapore airlines is the best in the world in my opinion with hundreds of movies, TV shows and music options to chose from all on demand.    The service was also excellent. 

The separate smaller cabin in economy is good.   Note the size of the TV.
