Watching TV on an airplane is the #1 reason I would buy a VR headset. The in-seat screen UIs are atrocious and they tend to only have ~4 or so episodes of any given show. Unfortunately, the Oculus Go's battery life is only about 2 hours according to the Ars Technica review[1]. Some planes have AC outlets, but YMMV.
