Just be aware that in a panic or even just a big hurry, people will not hesitate to go *over* the seats, not just down the isles. I remember seeing a video of an FAA airliner evacuation test and the presumably untrained, uncoached volunteers were hopping over seats faster than the people moving up the center isle.

I often request overwing exit row seating when I fly. That way I don't have to trust someone else to figure it out and I can be in a position to be actually helpful.
