Seat Maps on a 777 three class for WT+
I am on flight 2168 from Fort Lauderdale to LGW in July. I have picked seats 11 a and b on the seat map which is the second set of two seats by the window in WT+ on the left. There are four rows of 2 4 2 configuration. However, when I look at the sat maps for the ba for the 777 three class, they all are in the twenty something range. Is there a new configuration that is not on the British airways web site???
