After countless calls, I finally got hooked up with a TSA supervisor who helped me. Turns out, the airline put someone else's tag on my suitcase.
This Supervisor replayed the video ( with me on the phone giving details) of when I walked with my bag for TSA inspection, and he compared the log where he discovered the incorrect tag. As soon as I got the name and tag number that was recorded, I called Southwest. They were shocked how I found my own bag. Honestly, Southwest dropped the ball and drug their feet on this one. At least everything in the suitcase was there, including my wife's new camera, and of course my XDS. Lesson learned, don't assume or expect the suitcase tags are always yours.
