Is there a way with Star Alliance (United and Lufthansa in particular) to track the location of your bag. My wife and daughter are sitting in IAD for an 8 hour layover before leaving for Munich. She is worried that her bag may be sitting somewhere off the beaten path waiting out this long layover and may not make it onboard their flight.

Anyway to be proactive and track the checked bag locations with either United or Lufthansa?
