I no longer travel for work, so it's all about me. Unfortunately, I've never been able to sleep much on a plane (generally falling asleep around 30 minutes before arrival on short haul flights, and only intermittently on long haul, whether in J or Y). So it's usually a mixture of listening to all the baroque, classical, and then country music on the IFE while showing the map, flipping through the movies and TV shows and maybe watching one episode of something or other, reading the newspaper, playing games on my cellphone, eating (business or long haul), drinking (champagne in J long haul, beer in Y long haul, tea and water on all flights), reading the in flight magazine, and getting books and magazines out from my carry-on to read.

And spending 1/2 hour settling down to sleep for 5 minutes, multiple times on a long haul.

And queuing for the washroom.
