I know this is not answering the question from the poster but I found meditation very helpful during my recent 15 hours flight.
It is very rare to find such a long time alone in an almost quite and non-stimulating environment. Getting meals served to you on your seat and knowing that you are
stuck here for next many hours takes away the planning ahead part of the head. I found it easier to be with my breath and thoughts.
I also drifted in and out of sleep during this time and felt very relaxed. It helped me upon landing to minimize effects of Jet lag. I believe it was more helpful than any talk or video and could also help getting some good insights.
