Wow! I am fortunate to have never had that regular bag loss. I recall a tight connection MUC~FRA~DTW, we were late into FRA and I knew that the bag would not have made it. At DTW, so many people were shocked that their bags were not there. Early on I learnt the mantra: When your bag is checked in - you must presume that you will never see it again.
But, does the Cabin think that bag mishandling/loss has improved?
