I am booked LHR-EWR 24 March and the seat map makes it look like a 3-class 777 in that has Row 1-5 and 10-12 in a 2x4x2 configuration. The strange thing is on seatguru, seatexpert and the BA seating guide here on FT as well as on BA.com I can't find a 777 that features a CW Row 5. They all seem to show Row 1-4 for CW in a 3 Class 777 configuration.

I wanted Row 5A as it appears that this would face the back bulkhead of the first cabin and therefore have access to the aisle without stepover (a.k.a. 14A/K on the 744 Hi J configuration).

My thought is this was one of the new three-class 777s and maybe the maps and guide here at FT haven't been updated.

Or is this a BA.com mistake?
