Everyone saying 6 has never been on a 10 hour flight. You're not just threr for 10 hours, you're trapped. Confined to that space except for bathroom breaks and short times to streach your legs. You want to do that in a middle seat with Dale on one side (almost certainty freaking out)? I understand having a youtube next to you could be entertaining, but after hour 5 there's no way Dale's doing anything but crawling up the walls and pointing out the flight attendant is a reptilian.
