Has anyone flown direct to Lima from Gatwick on British Airways recently??

I need to know whether the aircraft used which I believe is a 777-200 has been fitted/updated with the new economy cabins? The exact flight number of the aircraft that I'm enquiring BA2239. The registration number varies but BA use the G-YMMs, mainly B,C,D,R,S and a couple more I think. And according to some research all those aircraft are using the Rockwell Collins IFE 8.9 inch screens. Is this the new IFE system? I'm guessing so?

I need to know if they are the old cabins. If so, then I'd rather fly with Iberia. The old style looks rather uncomfortable for a 12 hour journey and with ancient IFE screens around 6.5 inches which are the worst of any modern IFE.
