Can you answer Kaytee’s question about Luggage?:

I recently flew to Europe and had a connection in Amsterdam. The first plane was late and I had to literally run to the next gate to make my connection. I did make it, but was sure that they did not have enough time to transfer my luggage. To my great surprise, my luggage arrived at the final destination together with me! How did they do it, is there a highly efficient luggage transfer system in airports? Is it possible that my checked-in luggage traveled by a different route?
