We appreciate your feedback and apologize for your inconvenient experience with this product. Indeed, your padlock is a TSA-accepted model so it is likely that the TSA screener may not have been adequately trained to recognize the red and white diamond logo on the lock.
We can submit a notice to the TSA and we would like the following information to complete the claims process.
These infomation will be sent to our licensor, Travel Sentry, and they will address the incident with the screener authority at the airport where the lock was cut.
• Date of travel:
• Name of departure airport:
• Airline, flight #, time of flight:
