How accurate are the 3D seat maps on United's site? I'm getting ready to book next year's flights, and the SFO/OGG leg (UA 539) is on a 737-800. United's 3D model shows that 11 DEF, and possibly 10 ABC, appears to be aligned well with the window. However, SeatGuru basically says that 10 is misaligned and 11 is missing a window entirely (both sides). I know this is nitpicky, but I figured I'd ask anyway.
