Airbus Bag2Go smart luggage wields GPS and RFID

Many of us avoid flying with checked baggage when possible, and for good reason: even a simple delay can sour a whole trip. Airbus' new Bag2Go prototype could save us from having to pack light, however. The smart luggage carries a raft of sensors that work with an iOS app to bypass the usual airport drudgery. Its RFID chip lets travelers check in their bag and link it to every step of their itinerary; in theory, couriers can ship baggage to the hotel at a lower cost than usual.
