Yes, the seatmap is accurate. And yes, the G-H seats in rows 10 through 16 do have additional leg room (in reality they don't precisely align with the adjacent center seats). The asymmetry of the seat arrangement has to do with the asymmetrical lav arrangement at the aft end of the forward coach cabin.
Is this MCE seat map correct for the 330-200? Why is the 9-16GH side MCE but not the 9-16AB side? And rows 23-26, excluding 26ABGH?
I noticed this when booking a domestic CLT-PHL flight (where I grabbed 6C) and thought it seemed odd for the mismatched rows.
