Who lost your bag anyway dear sir?
Last time I flew Luftis on FRA-EWR I've arrived without my check-in bag, was given 50$ of traveller checks (or how are they called?) and assured that it will be flown in next day to EWR and FedEx'ed to my location (not NYC). It all happened exactly like that, although security control broke my lock (not TSA) and confiscated frankfurter sausages
It all comes down to ground handling eventually
