I agree with the above, especially people who aren't prepared with their ticket/boarding pass/whatever, and those behind me who use the back of my seat to hoist themselves up.
Regarding people on moving sidewalks who stand on the left, what's your take when there are two sidewalks your direction (ORD between United's terminals, or SFO from United's gates)? My opinion is that both should be stand right / walk left, but I get dirty looks and comments implying that they think only the left hand walkway is for walking.
In general, though, this thread reminds me of a friend's comment that she avoids flying in summer because of all the "amateurs" out there!
