Hello everyone. I have a question regarding the seating layout for WT+ on BA's 747 299 passenger configuration (Flt 193 LHR-DFW). I have decided to purchase seats in advance and am considering seats 30J & 30K. (The exit row seats are blocked out). Seat guru says these are standard seats but I am hoping to get a little advice about my selection. It looks like the nearest lavatory is behind in WT. Any insight? Thanks so much!
