> zone out to a book or movie I can do that when I'm home. But at home I can also stand up, go for a walk, or go to the restroom without having to wait in line, or go to sleep, etc. In a long flight I can do none of these. I can instead suffer from dry air, I have a hard time sleeping in something that is a bad approximation of a bed, etc, etc. Oh, and don't ask me if my kids enjoy 10-hour flights (of which they have experienced a few, unfortunately). Sometimes it's so stressful for them that their immune system is ravaged, so we spend time with doctors instead of enjoying vacation. The shorter the flight, the better for me. If I can afford it. But before it's cheap it first has to exist.
