Use locks designed for airport security inspections – those with a standardized master‑key opening (look for Travel Sentry or similar accreditation). Single‑use nylon fasteners and non‑approved cable fasteners will be severed by U.S. security screeners if an inspection is needed; such severing is common and replacements are not provided by screeners.
Acceptable options: travel locks with universal inspection ports, keyed or combination locks labeled for acceptance by U.S. screeners, and numbered tamper‑evident seals sold with tracking documentation. Avoid disposable plastic fasteners if you want a high chance that an inspection won’t permanently damage the closure.
Practical steps before departure: keep valuables and lithium batteries in carry‑on; photograph the exterior, serial numbers and any seals; register approved lock model and key number if applicable; attach a sturdy external ID tag. If a seal is cut, report it to the airline counter immediately and retain photos as evidence for a damage or lost‑property claim.
Risk and liability: airport security authorities have the legal right to open checked items for inspection. Using approved inspection‑accessible locks reduces the likelihood of destructive entry but does not guarantee the bag will remain closed; non‑approved fasteners are likely to be removed and may result in unrepaired damage for which the airline or security agency typically disclaims responsibility.
Plastic Cable Seals on Checked Bags – Practical Guidance
Avoid single‑use plastic cable seals; U.S. airport security routinely severs non‑approved closures and will not restore them.
Preferred security options
Use locks accepted by Travel Sentry (look for the Travel Sentry logo). Locks recognized by the Transportation Security Administration allow inspectors to open and relock without destroying the closure. Choose a metal‑shackle padlock or a resettable combination cable lock with a visible accreditation mark; these are sold at major retailers and typically cost $10–$30.
If a non‑approved closure is used
Expect removal: screening officers usually cut disposable seals and place a standard inspection notice inside the bag. Photograph the packed contents and the closure before check‑in, retain receipts and serial numbers for high‑value items, and keep spare approved locks or replacement seals in your carry‑on. At the airport, report damaged or missing property at the airline counter; for U.S. flights you may also submit a complaint to the Transportation Security Administration through its official channels. Note that many overseas authorities do not follow the Travel Sentry system and are even more likely to destroy single‑use closures.
Practical tip: move irreplaceable or valuable items into your carry‑on, and treat disposable seals as tamper‑evidence only–not as theft protection.
Are non‑approved cable fasteners permitted at airport security checkpoints?
Use airport‑approved locks or certified tamper‑evident seals instead of single‑use plastic cable fasteners for checked baggage; security officers will cut non‑approved fasteners and leave an inspection notice if they open the bag.
Single‑use plastic seals and cable fasteners are not prohibited items to carry through passenger screening, but they are not recognized as acceptable locking mechanisms for checked items. U.S. passenger‑screening authorities and most carriers have authority to open and reseal bags; when opened, non‑approved fasteners are removed and discarded. Expect a “Notice of Baggage Inspection” or similar tag placed inside.
Handling at checkpoints
Screening personnel use cutting tools to access secured checked items and will not attempt to preserve disposable plastic fasteners. Numbered tamper seals can provide evidence of interference but do not prevent access. If a carrier’s agents must be able to open your bag, select a lock they can operate.
Practical alternatives and tips
Choose combination or keyed locks labeled as airport‑approved, buy certified tamper‑evident numbered seals from security suppliers and photograph serial numbers before travel, and add a durable external identifier such as best luggage tags leather.

Will airport screeners cut or remove cable seals during bag inspections?
Short answer: Expect security officers to cut or remove any plastic security seal or cable fastener that blocks access to a checked case; use master-key-compatible locks or keep valuables in your carry-on to avoid damage or loss.
- Legal authority and routine practice: Federal screening officers are authorized to open and inspect both checked and carry-on items. If the traveler is present at a checkpoint, officers normally ask the traveler to open the item; if not, or if access is obstructed, officers will break locks or sever seals to complete the inspection.
- What happens to removed seals: Non-approved seals and restraints are usually cut and discarded. Officers typically leave a printed inspection notice inside or attached to the item stating it was opened for screening.
- Carry-on vs checked: For cabin items, officers will request the passenger open the bag rather than cutting seals. If the passenger cannot or will not open it, officers may still disable the securing device to inspect contents.
Recommended precautions
- Use screening-authority‑approved locks (e.g., Travel Sentry, Safe Skies) on checked cases so officers can open and re‑lock without cutting. Look for the approved-logo on the lock.
- For tamper‑evident plastic seals or numbered security straps: treat them as disposable. Expect them to be removed if inspection is needed; photograph and record serial numbers before travel if you want evidence of tampering.
- Place high‑value or fragile items in your carry‑on. If impossible, pack valuables in a crush‑resistant internal pouch and document contents with photos to support any damage claim.
- If you prefer not to use approved locks, use heavy-duty cable restraints only if you accept they will likely be cut during an inspection.
After inspection: open the case at the baggage service office before leaving the terminal. If you find damage or missing items, file a damage or loss report with the airline immediately and keep photos of the removed restraint, the inspection notice, and the damaged contents to support a claim.
How to use approved locks and alternatives for screened bags
Use a Travel Sentry–accepted combination or keyed lock on checked bags; choose models bearing the red diamond mark from manufacturers such as Master Lock, Samsonite, or Travel Sentry licensees so screening personnel can open and relock without destroying the device.
Selecting an approved lock
Pick a 3- or 4-digit combination or small keyed padlock that explicitly displays the Travel Sentry logo. Confirm compatibility with your bag’s closure pulls: the shackle or cable must pass through both pull loops or through one pull and an anchored eyelet. For hard-shell cases prefer integrated combination locks certified by the manufacturer.
Avoid using easily guessed codes (birthdates, repeated digits); record the code securely and keep a paper backup separate from the bag. For keyed models make two duplicate keys and store one with travel documents, not inside the same bag.
Practical use and alternatives
Attach the approved lock to the main compartment pulls so it prevents accidental opening but does not obstruct handles, wheels or carrying straps. When sealing soft bags with small pull holes, use a short cable-lock with a Travel Sentry–approved lock head rather than forcing a large shackle through tiny openings.
Use tamper-evident single-use seals (pull-through plastic seals, numbered adhesive tamper labels) as visual indicators; expect these to be removed if an inspection requires access. For higher mechanical strength choose reusable steel cable locks or coated-cable padlocks with compatible approved lock heads.
Consider a high-visibility woven travel strap with an approved lock built into the buckle to prevent accidental opening and provide an obvious tamper signal; choose straps rated to resist basic cutting tools and avoid straps that cover airline tag zones or airline barcodes.
For international itineraries verify acceptance of the chosen approval program at origin and destination airports; acceptance logos and manufacturer listings are available on Travel Sentry’s website. After each trip inspect locks and seals for deformation, log serial numbers (for numbered metal seals) and replace any single-use indicators removed during screening.
Place a single-use plastic security seal through both main compartment zipper pulls and a reinforced external anchor (D-ring or sewn loop) so the indicator shows any forced entry yet leaves the bag operable for inspection
Recommended hardware: clear or brightly colored single-use plastic security seals, strap width 2–3 mm, loop length adjustable to 100–150 mm; visible printed serial number on the head.
Exact placement: thread the seal through the holes in both primary zipper sliders, then through a nearby fixed anchor point on the case frame (metal D-ring, factory-sewn webbing loop or reinforced grommet). Position the locking head so its serial number faces outward for quick visual checks.
Slack and orientation: leave about 15–25 mm (0.6–1.0 in) of loop beyond the head – tight enough to prevent accidental movement of the sliders but loose enough to let an inspector lift the pulls without catching fabric. Route the strap so it runs parallel to the zipper line, not across it, to avoid jamming the track.
Avoid these locations: do not route through telescoping handle tubes, wheel housings, built-in combination lock openings or interior compartments; those placements either block normal access or risk damage during routine baggage handling.
Multiple compartments: for roll-top or separate front pockets, use one seal on the main compartment and optional smaller seals on high-value external pockets. Label each seal head with a matching written code on paper inside the bag (beneath a flap) to confirm that the exterior seal corresponds to the interior note after inspection.
Inspection-friendly setup: place the seal so an inspector can open the zipper fully by releasing one slider from the other (if the design allows) without cutting the strap; if removal is required during screening, the serial will show if a different seal was applied afterwards.
Durability tips: choose seals rated for outdoor use (UV-stable plastic) if travel includes exposure to sun or moisture; check that the head’s locking mechanism resists tampering with fingernails or small tools – metal cable seals are an alternative where higher physical resistance is desired, but they increase the risk of damaging zipper pulls.
Placement checklist: both zipper sliders → fixed external anchor → serial facing out → 15–25 mm slack → avoid handles/wheels/lock ports → visible color.

If airport screening staff open your suitcase or cut a plastic seal: immediate recommended actions
Photograph the inspected case and its contents immediately with timestamps visible (include boarding pass, baggage tag and watch/phone clock in at least one shot).
At the checkpoint
Request a written search/inspection notice and the name and badge number of the agent who conducted the inspection; keep a paper copy or take a clear photo of the document. Ask for a supervisor if the agent refuses to provide identification or an inspection receipt. Do not repackage fragile or suspect items until they have been recorded.
Make a quick inventory of removed or damaged items, show the list to the screening agent and ask them to sign or stamp it. If items appear missing, report the discrepancy before leaving the airport and obtain an incident or report number.
After leaving the airport
Send the timestamped photos and the inspection notice to the airline and to the screening authority via their official claims or customer-service channels; include flight number, date, airport, and the incident/report number. Save all original packaging, receipts, serial numbers and warranties for any items that are damaged or missing. If available, file an official damage/missing-item claim with the airline within 24–72 hours and with the screening authority as soon as possible; record confirmation numbers and contact names.
Keep copies of every communication (emails, messages, claim forms). If you purchased travel insurance, open a claim using the same documentation. For high-value items, consider filing a police report to support insurance or compensation requests.
