Accurate data about checked baggage is no longer optional. The journey of a checked bag is long and a significant source of stress throughout the air travel industry. Passengers fear their luggage will be lost or damaged and airlines dread incurring costs associated with the correction of mishandled baggage. The pain of customers and airlines can slow down entire airports, costing these travel hubs both financially and reputationally. In 2017, approximately 4.6 billion bags were lost or delayed worldwide, costing the airline industry $2.3 billion USD.
