It is difficult to track luggage after an airline loses it. Often times, it never turns up at all. In April, the U.S. airlines mishandled over 141,000 bags. “Smart luggage” uses GPS tracking chips that are embedded in the bags, and they transmit their locations to travelers. Some of these tracking chips can even contact airlines directly when they get lost. Bag2Go, a product introduced by Airbus, can be tracked via a smartphone app, allows for self-service check-ins, and can weigh itself. AT&T has also developed a similar concept. Both companies intend for the luggage to work with airlines so that it can be delivered directly to a person’s home or hotel, saving people from the agony of lost luggage.
