Actually, that flight is by Singaport Airlines and is all business class. Their seats are 30" wide (lots of room compared to the roughly 18" you get in a regular coach seat) and can be reclined fully flat into a bed. They have personal entertainment stations embedded with lots of movies, TV, and music. Service on Singapore Airlines is apparently incredible too.
I was once booked on this flight but my trip got cancelled. My brother did take it though and he said it was the best flight he'd ever been on.
I flew Singapore Airlines on the Airbus 380, riding in coach from Heathrow to Singapore.
Wonderful service! Singapore is a wonderful airport.
