Share your realllllly long flight tips, please

<p>On a flight back from India I pretty much stood for a couple of hours in the back of the plane. Eventually a gentleman who looked like he could have been a Marshall came and stood near me for about an hour. I guess my behavior was unusual, but boy did my back and knees feel good. Other than that I slept in my seat or played games on my iPad. I definitely like a neck cushion and sound reduction headphones as well.</p>
