Should I Lock My Luggage When Flying?
Locking luggage can deter casual theft and add peace of mind, especially for checked bags, but it is not foolproof. Travelers flying to, from, or within the United States should use TSA-approved locks so security officers can inspect bags without cutting the lock. For carry-on luggage, a lock is usually optional. The best choice depends on your itinerary, bag contents, and tolerance for risk.
