One of the best plane trips we took when our daughter was small was a Japan Airlines flight from Los Angeles to Narita, Japan. Instead of letting you figure out what to do to amuse yourselves for the hours on end it takes to get across the Pacific, they help you out. We played Sky Bingo as part of the entertainment. Whoever wanted to play got a Bingo card and the numbers were shown on the big screen. (I think that’s how it worked.) I do remember that our daughter was given extra prizes just for being cute. I have no idea if Sky Bingo is still played, but it was a great idea, I thought.
Another fun thing was the exercises we were led through after we had whatever sleep we could snag. I loved the exercises. These were the kind you do in your seat, but meant to get your blood flowing and the kinks out. Here is a video I came across on You Tube of exercises being done on a plane you can even try at home. This is some Chinese flight, I assume. You can practice counting in Chinese while you watch.
