Forget tablets in the airplane cabin -- Virgin Atlantic thinks wearables are where it's at for improving your travel experience. The airline has begun trialing a greeting system that uses Google Glass and Sony's Smartwatch 2 to streamline the airport check-in process for Upper Class passengers. Staff at Heathrow Airport's Terminal 3 are using the technology to greet travelers by name, provide flight updates and translate any foreign language information. The test run will only last six weeks, but Virgin already has dreams of future software that lets staff know what food you like. Let's just hope that any potential wide-scale rollout accommodates those of us in the cheap seats.
