Not something that could be seen in a picture, but I had the misfortune of being seated next to The Bickersons on a flight from DTW-LGA this week. Fortunately, I could almost drown out the argument by cranking up the volume on my iPod. I popped one earbud out to ask for a Coke and the woman of the pair said "my goodness your music is loud", to which I replied, "so is your arguing". Didn't quiet them down one bit. Ugh.
Seems like the perfect situation for noise canceling headphones. Not only would it preserve your hearing it would lessen the ambient noise from your seat mates' convo.
