I have a checked bag that mysteriously made its way to BWI rather than PHL. I flew 3 days ago from DFW. 2 days ago the app showed the bag as "unloaded from plane" in BWI. I filed a claim in PHL and then followed-up by phone, but phone agents are saying that the bag hasn't been located (despite the "unloaded in BWI" comment in the app). Anything I can do to expedite the folks in BWI finding it and acknowledging that they have the bag?
