To the OP and to all travelers who check bags.... consider getting a luggage tracking device, like the Apple AirTag. They have saved me a couple times. Once when flying from AMS to SFO. My checked bag did not come out on the carousel along with everyone else's and airport personnel told me that all bags had been unloaded, but my AirTag told me the bag was at SFO. So, I waited for a bit, and sure enough here comes a few more bags. If not for the tracker, I would have left the airport. Then, on a flight from BER to MUC to SFO, again, no bag, but AirTag told me that the bag was still in MUC (I had a short connection; I made the flight but my luggage did not). So, I knew not to wait, and I was able to track my bag all through the home delivery process, which took 2.5 days.
they are relatively inexpensive. I put one in my carry-on too because I'm often asked to check my carry-on at the gate.
HAPPY TRAVELS TO ALL!
