Super perfect Flight. Not only Singapore airlines, Changi airport and Haneda airport too. They are super professional and very nice to passenger. Singapore Airlines B777-300ER is very comfortable. Seat designed for giving passenger feel like you want to stick with the seat. Very comfortable, in-flight entertainment is fun and nice, Cabin crews are gentle and nice. Food is good.
I can say that this I really love this flight. I will fly with SQ again definitely
