SOME still offer free entertainment
I flew from Atlanta to Malaysia last year. We had the usual horrible Delta cattle cars to New York and back from Los Angeles. HOWEVER...
We flew China Southern for the long haul. They did everything possible to make 14 hours in a flying tube a pleasant experience. Real food, which was actually very good. Entertainment? Totally free. It took me over 15 minutes just to browse through all the offerings in the system. TV shows, current films, art films, in various languages with your choice of subtitles. Incredible variety of music. All this on new Airbus planes with tons of legroom. On Delta my knees hit the seat ahead. on China Southern, I had eight inches of freedom, and I'm six feet tall.
Air Asia had roomy planes as well, but they were short hauls not needing entertaining.
