When you board a United flight, the flight attendants announce that you will need to download the latest United app to use onboard entertainment, however, since this version is over 100MB (its 101MB) it cannot be downloaded without wifi, so there is no way to download it while sitting on the plane pre-flight. Perhaps United could lose 1MB from the file size to fix this? Thanks! :)
