So far nothing - when you call AA they tell you they will send a message to the local team to deliver it. Seems roughly as effective as me trying smoke signals. I had more luck with China Eastern that lost a bag on a flight to BKK - and I then asked them to send it to Austria (though they sent it to Australia first - I had to learn the Chinese word for "Austria" to explain the difference.) But by now it took them less time to get it here than AA to do the same from MUC
