UAL to offer free streaming video in-flight to iOS users1
Those with an iOS device will first have to download and install the United app from iTunes. The airline also suggests that you recharge your battery before you board a flight. There is no fun in getting into a great movie or television series and finding out that your batteries have let you down.
The app will offer certain controls necessary for viewing video such as start, stop, pause and rewind, and the content is sponsored by the MileagePlus Explorer Card. Certain content will play over the United Portal without requiring the app.
