Weve seen Google Glass on the faces of surgeons and police officers, and now flight attendants could be greeting travelers with Googles wearable display. Virgin Atlantic is testing a new system in which airline workers and gate agents use Google Glass and the Sony Smartwatch 2 to streamline the check-in process for passengers. The trial run is currently being conducted at Heathrow Airports Terminal 3, where the wearable display and smartwatch are being used to provide Upper Class passengers with real time information on flight status.
