On the other hand, the 738 only tends to fly domestically (plus very "nearby" international). Does it even support that many different kind of plugs?
738 plug is identical - supports the same plugs. The light is on top, which mean the ground pin is below.
Here is what is interesting, some images show it downwards
But the 787 pics show ground up
