Can I lock my luggage?
Bags traveling within a single country must be locked. Failure to lock Items will void your right to file a claim for lost or missing contents.
Bags traveling between two countries must be unlocked as they may have to be opened as a normal part of the customs screening process. If bags are locked, including those using "TSA approved" locks, and customs cannot open Item through other means, then the lock or seal may have to be broken, which may cause damage. Locking any Item traveling internationally can cause extended delays and will void any warranties expressly provided to you herein.
Please note that TSA locks do not work Internationally because international Customs officers do not have TSA lock keys.
