The seat map above is still a work in progress. The cabin layouts correlate to BA's seat diagrams but the toilet arrangements aft of the Club World cabin is subject to verification. If anyone is able to review the map and confirm, I'd appreciate your help.
Have done two BWI trips in CW on this configuration in the past few weeks and yes the toilet layout you have there is right.
Worth noting that 4A and 4K suffer badly from misaligned and missing windows - furthest window forward is obscured by the seat hood, middle window is missing, third window (furthest aft) is there but obviously no view from it when seated.
