Delta Air Lines has updated its mobile app so that passengers can now track their checked luggage from the moment it's dropped off to when it ends up in baggage claim (with any luck, at the correct destination).
Using Radio Frequency Identification (RFID) tags, the app's new feature lets your follow your luggage's journey via a suitcase icon that appears on a map of the U.S. Tap the icon and you'll get additional information about your bag's location. Previously, the app only provided updates on where luggage had last been scanned.
Delta's update joins other recent efforts by carriers including Alaska Airlines and American Airlines to use technology in order to keep customers better informed about where their belongings are at any given moment.
