The move by British Airways reflects a greater trend of the airline industry embracing radio frequency identification technology. Delta rolled out RFID luggage tags back in 2016, allowing passengers to view their bag’s location on the FlyDelta mobile app. Last summer, the International Air Transport Association (IATA) voted to deploy RFID globally by 2020. At that point, all bags will be tracked with RFID baggage tags from the moment they’re checked. This will allow passengers and airline employees to view their bag’s location at all times.

Losing your luggage is every traveler’s worst nightmare, but airlines have gotten better at prevention. Over the past decade, airlines have seen a 70 percent drop in lost luggage according to SITA. Still, tracking down lost or mishandled baggage costs the airline industry a significant chunk of change — an estimated $2 billion back in 2016. Deploying RFID tracking will likely save airlines some money, not to mention spare headaches for travelers.
