More people are expected to fly home this year for the holidays than any other form of transportation. One risk that typically comes with flying, is lost luggage. There is nothing worse than getting to your final destination, only to find your stuff didn't make it. Delta Airlines just installed a $50 million system to help you, and them, keep track of your bags. The tracking system starts with the luggage tag they place on your bags at check in. They now have a tracking chip on them that is scanned as your bags move through the system and on to the plane. If a bag is put on the wrong plane, the chip turns red to alert the staff. Passengers will also get cell phone alerts as their luggage is moved through the system. Delta is rolling this technology out at 84 airports across the country.
