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. Bag2Go should also provide some reassurance through GPS tracking and alerts to any possible tampering. Airbus is still early into development, but it foresees a business model where customers can either buy a Bag2Go suitcase at a premium or rent one for a long vacation. As for us? We'll just be happy if our luggage avoids an unexpected detour to Belize.
