Which is more accurate? I'm assuming Delta. I'm trying to pick a seat for ATL/FCO and don't want to be over the wing, but it appears the wing is in different places depending on which chart you look at.

I would definitely trust Delta to have more current and accurate info on their own fleet over seatguru. Of course, they have the right to switch aircraft at the last minute but I think that's unlikely.

Delta flies 767 on this route and that's what I'm looking at on Seat Guru for Delta. It's just their wings aren't quite over the same rows even though it's supposed to be the same plane.

If you check on the 763ER Version 2 on seatguru.com it shows the wing from rows 17-28. Which is the same info as on dl.com. The "Version 1" figure is from 18-28, almost the same thing.

There's no exact definition of the location of an aircraft wing. Row 16-17 may be in front of the actual wing, but looking at pictures on airliners.net, you're parallel to the engine if you're sitting from the first row of the coach to the emergency exit.

If you're interested in taking in-flight pictures, you should get a seat as far back as possible, as even if you sit in say Row 29, you will still see mostly the wing out of your window.

rkkwan - Yes, Seat Guru shows as you said, but when I look at my seat on Delta, rows 21-31 were over the wing. I'm in 33G (have to have a window to lean against to sleep).
