Delta Air Lines has rolled out a new feature on its Fly Delta smart-phone app that allows passengers to track checked luggage in real time and know which baggage carousel has their bags.
Jonathan Mayfield of Delta's mobile product team explains on the airline's blog: "Just enter the number on your bag tag receipt -- or iPhone users can scan the barcode -- and watch your bag's journey from departure to arrival and all points in between." It's kind of like tracking a UPS or FedEx package.
