Until you have your bags back, just sit back and enjoy yourself. Nobody has access to any better information than is in WorldTracer and you can see that for yourself. Calling simply raises your stress level and won't actually cause anybody to do anything. Just make certain that your mobile number, a local contact number and bag tag are correctly entered and updated should you move around.

The reality is that nobody is looking for your bag. Rather, it will simply show up somewhere as unaccounted for. That might be at AMS and it might be anywhere else KL operates as the bag may have been loaded onto the wrong aircraft and no scanned. But, unless it has been destroyed or stolen, it will sooner or later find itself on a luggage cart and someone will look at the tag, scan it and see that you have reported it. The bag will then be routed from wherever it is to wherever you are.

If the bag is not located at 20 days, it is considered lost and you are entitled to its fair market value to a maximum of approximately EUR 1,150 per passenger. In the meantime, if you have interim expenses, you may incur those and submit those to the last delivering carrier (KL?). Best to wait until your return home when this can be handled without bother. Anything reimbursed would be deducted from the EUR 1,150 if the bag is lost.

Hopefully KL's generous cabin baggage allowances mean that you have the first 3-4 days of what you need in the cabin baggage, so none of this is a problem.
