On a recent trip from MSN to MCO, I checked two bags with TSA approved locks. When I retrieved the two bags, only one had the TSA lock on it. The TSA locks I purchased have an indicator telling me if it has been inspected or not. The one remaining lock had an indicator of RED, which meant it was opened and inspected. Both bags had the TSA slip in them, except one of the locks was missing. Nothing was missing in the bags, so I never reported it, but am a little frustrated that I lost one of the locks! I wonder what exactly happened. This is the first time that both my bags were searched.
