Best use-case by far. I was traveling internationally, and the airline left my luggage back in Europe. The airline had no idea where my bags were but, I was able to tell them exactly which terminal my bags got loaded onto. (where they lost signal) They looked up which flight departed that terminal at that time and were then able to route my bags to my final location and I had them within 24 hours.
