My mom follows Christoph Neimann's blog. The sketches on his recent blog pretty much described her experience (and probably most travelers') during her 13 hour flight to the Philippines. She can really relate to the sketch with the inflatable neck pillow. In the end, she wanted to fling that thing as far as she can.
There was also a crying baby on her flight. My mom's wished she was also in her bassinet.
My mom also wonders about those little holes in the windows. I, too, had asked the question when we went to Costa Rica. She said something about the window has double panes and something about condensation. I think she just made it up and she lost me quickly in thought.
Here is the link to the rest of the sketches. They are pretty hilarious.
