Are you saying that they should pre-download movies and music to listen to on the plane?<p>I use Google Play for music because it&#x27;s pretty okay at letting me cache local music on my phone, but I have no idea how well Rdio, Spotify, or Pandora do that. I don&#x27;t think there&#x27;s a way to do it on your computer at all, so if you only have a work phone that you don&#x27;t keep music on, streaming music might be your only option if you don&#x27;t want to listen to one of the 13 channels provided via the crappy in-seat audio jack.
