is it worth the extra money upgrade exit row seat

Exit Row Seat —Coach Choice seating Better travel experiences with more leg room.
Was it worth the $15 to upgrade from a standard economy seat to an exit row seat for a three-hour flight? Absolutely. (I'm 6' 4", and I need all the legroom I can get.)

This picture shows row 40 of a delta Airlines 757-300. I had the window seat on the left side of the plane (40A). Exit row passengers get to board right after the SkyTeam Elite members, so I was able to get a couple shots of the interior before any people started walking through.
