What I can read from above as it’s not really clear is that you haven’t reported this at your destination? Have you got a piece of paper with the tracking number? If you did report it then BA does know about this and deliver it wherever you specified. If you still haven’t reported the missing bags, the chances you will get it in the next few days are slim. I don’t think anyone in the US baggage office will be really interested where exactly the bags are, they can’t just call up people to search for your bag.
so call them Asap and report your missing bags if you haven’t done this!!
