Amazon has spent an exorbitant amount of cash to grow its Prime Instant Video service. Still, the company knows there's more it can do to make the offering better for subscribers. As such, Amazon is teaming up with JetBlue to bring Prime's on-demand video and music content to the skies, though only in the US. The new feature, which will be powered by JetBlue's super-speedy Fly-Fi internet, will be included as part of any existing Prime membership -- it's free in-flight entertainment, and that's a gesture people are likely to appreciate. Unfortunately, it won't be available until later this year, but at least that gives you some time to start building out your Watchlist.
