It really depends on the flight. I've done a TATL redeye (752, but the layout is the same) and didn't notice anyone around me at all until about 30 minutes out from landing, after the breakfast service. And I've done some longer domestic flights where folks stand up to stretch and hang out a bit. They've never been right on top of me nor have I felt I was getting bumped more than any other aisle seat.

Call it more like 2pm on the 6 train in midtown than 8:30am on that same train. :-:
