Some of the Emirates Boeing 777s also have suites in First - eight of them in two rows of four with, as TRHG described, the two centre ones in each row being able to be converted into what is effectively a two-person private cabin.
My wife and I flew this way DXB-MEL-DXB with EK last November. The product is excellent and we obtained the flights at not much more than the average EK business class fare via a well-known high street long haul travel specialist.
No bar area or showers on the EK B 777s though which may have been the reason for the competitively-priced fares I suppose.
I note the comments that some airlines are phasing out first class. Our connecting flights BHX/DXB/BHX (also B 777s) had no first class cabin.
