Of course if you are on a WiFi enabled aircraft you might be able to stream the content you wish to see. Having a radio (audio only) or even a text/Twitter feed in your content choices might be a useful backup if the video doesn't work for whatever reason. VPNs might also be required as many content sources are licensed to specific geographic locations and there's no way of knowing what geolocation you will get fromfonboard WiFi and may indeed change during the flight as the satellite uplink changes.
