There seems to be a paucity of information regarding the better WT+ seats on the 787-9 so I am wondering if anyone has any insight to share? I will be on BA280 from LAX - LHR on 4th May and I am currently in 18J.

I am assuming row 16 other than having extra legroom as being a bulkhead row suffers from the usual issue of a slightly narrower seat as the video screen is contained within the seat? Equally, row 21 is to be avoided owing to it being adjacent to the toilets?

For the 787-9 are the tray tables in the arm rest, or do they fold down from the seat in front? I know that the IFE control unit boxes are an issue in WT but I presume they aren't on the floor in WT+ and hence no seats are to be avoided because of this?

Thanks!
