Singapore. I didn't even mention first class, because I forgot about it -- they boarded the plane from a separate walkway/door to be insulated from the peasantry. I think they have individual beds/cabins.

I often fly Singapore airlines, and I've never been on first (which are the cabins you referred to).

In business class their seats fold into a flat bed, except on some older planes.
