Delta Adds Bag Tracking Functionality to App
Delta recently added a cool new feature to it's Fly Delta app - bag tracking. Now, you can enter your bag number (from the sticker they put on your boarding pass whenever you check a bag) and the app will let you know where it is.
I haven't actually used this functionality yet because I rarely check bags, but I think this is a step in the right direction. I've never actually lost a checked bag (now I've officially jinxed myself), but I have had some close misses and waiting in long baggage lines to check on the status is the last thing I want to do when I'm angry about a potentially lost bag.
