In my fortunately limited experience, Worldtracer is much worse than useless. Has anyone ever seen useful data there? Just yesterday I was looking at it to see how my son's lost bag was doing ("no information available") he text'ed to say the airline had just called and his bag was due at his hotel within the hour.

To the OP, be patient another couple of days. The airlines seem to take most of a week delivering lost bags. They seem to fly them around somewhat randomly, and after long enough, deliver them.
