Singapore Airlines tries to kill it.

The A380 may have the world’s first airborne double bed, but it won’t be put to the obvious use if Singapore Airlines has its way: “If couples used our double beds to engage in inappropriate activity, we would politely ask them to desist,” said the company’s Stephen Forshaw.
“There are things that are acceptable on an aircraft and things that aren’t, and the rules for behaviour in our double beds are the same ones that apply throughout the aircraft.”

While Silverjet tries to revive it — with a twist.
