Checked-bag details
Allowed and recommended, but specifically a TSA-approved lock (marked with a red diamond logo) is best — if your checked bag needs manual inspection, TSA has a master key to open these without cutting them off. Non-TSA-approved locks may be cut off if inspection is required.
Special instructions
Look for the red-diamond "Travel Sentry" logo to confirm a lock is TSA-approved.
FAQ
- Will TSA cut off my luggage lock if they need to search my bag?
- Only if it's not a TSA-approved lock. TSA-approved locks (marked with a red diamond logo) can be opened with a master key and relocked; non-approved locks may be cut off.
