the big brother of checked bags
If you can't avoid carrying on your bag, and have to check your bag and pay ridiculous fees, you know there's now extra anxiety about your bag getting lost. Well fear no more with Delta's mobile app, that has multiple features, including a way to track your bag like you can track shipped packages.
To promote this feature, Delta created a video that captures the trip a suitcase takes from check-in to landing on one of their flights. A suitcase equipped with cameras takes the journey.
Whether this is accurate or just really well edited is anybody's guess, but the tracking feature is a nice bit of security when travelling.
