ANZ 747s were unusual upstairs - the rear was economy (2-3 I think) and the front was Business with the seats you described 1 - 1 in a herringbone pattern. I believe Virgin Atlantic use the same seats. BA patented theirs (I think) so they are the only people with that specific layout. There are a lot of variants out there and some airlines have multiple layouts; I think Air Canada have at least 3 kinds of Business class seats.
