Just found this thread and wondered what the outcome was of this missing row 37 on the seatmap? I'm on the same plane shortly for the LHR to EWR route, and currently in row 36.
I suspect there isn't actually a gap there - perhaps its a row of seats they don't sell for some reason?. Just want to be sure I don't get a seat that doesn't recline, or one that has people standing behind it leaning on the chair etc..
