Delta has launched a new service on its FlyDelta mobile app, allowing passengers to track their checked luggage on a map.

The service builds on the carrier’s existing Radio Frequency Identification (RFID) bag tags, and the rollout of RFID technology at 84 airports in the US.

FlyDelta users can now view a map on the app, showing the last scanned location of their luggage.

The display starts by showing a zoomed out map of the US as the bag travels between airports, before zooming into airport view and showing journey “pins”, with the last known location identified by a suitcase icon.

Tapping any of the pins or the icon will bring up additional text information about the location.

Delta says that “domestic stations now offer map view of the bag’s journey and international stations will receive this technology in the coming months”.

Later this year the carrier will also rollout push notifications, allowing passengers to be automatically updated about the location of their bag.

Commenting on the new service Bill Lentsch, Delta’s Senior Vice President – Airline Operations and Airport Customer Service said:

“We’re the first carrier to offer this level of visibility. From the moment our customers drop off their bag, we want them to know we’re looking out for it every step of the way and working to take the stress out of flying one innovation at a time.”
