What is the point of paying for special luggage locks for which TSA is supposed to have keys, only to have them cut off for access? For the second time in about three years, both on American Airlines, my lock has been cut off. The first time the damaged lock was still hanging there, this time the lock was completely gone and the love note left inside by TSA confirmed my suspicion that it had been cut off rather than fallen off due to improper closure on my part. We carry anything of any value in our carry-on luggage, but I still do like to lock my bags if we are checking them (which we tend to do on the return trip when the bags are heavy and/or expanded with souvenirs). What does everyone else do?
