You’ll be able to watch movies and TV shows on your phone or iPad streamed to you from the plane. Presumably, hopefully, these will be better than the stuff that they’re showing on screens in the planes now. Not sure if these would come in any stronger than, say, Netflix, which it seems would also be possible if there’s enough of a strong wifi signal to enable movies. Anyway, it’s good news on a long flight, especially if you forgot to load something up on your device before you left home.
