It is mentioned in this thread's wiki, and I think CIHY has also flagged it up elsewhere in a question on reclining seats. It is very disappointing since BA is effectively introducing 6 non reclining seats in WT, whereas up until August all longhaul seats, in all cabins, had full recline. The seats in question are the final row of the forward WT cabin, which is extra odd, since if one was looking for non reclining seats they would usually be the very last row of the last cabin, at least on other (non BA) aircraft. It will be interesting to see how BA handles this since unless it is both flagged up to passengers in advance, and said passengers given the option to move to other seats, this isn't going to look good in terms of what is advertised and what customers may expect. The extra inch in front isn't going to count for anything at all if the previous row's passengers have gone into full recline.

I haven't checked, but I'm presuming the middle block 3 seats in row 35 do recline.
