> BTW, to give this a software dimension: I was recently on a flight with an airline I hadn't used before, and I really liked a UI in their in-flight infotainment that showed the entire flight as a timeline with all meaningful events penciled in (when the meals are, etc.) and a recommendation during which blocks to sleep. That was really nice and thoughtful.

Do you recall which airline this was? Given similar pricing, this seems like a useful differentiator that would sway my decision of which airline to pick.
