Use a single Transportation Security Administration‑approved security device on the main zipper or access point; if adding a second security measure, make it tamper‑evident and ensure the approved device remains accessible for inspection to avoid destructive opening.

The U.S. security agency authorizes two recognized systems – Travel Sentry and Safe Skies – which permit screened agents to open checked bags with master tools and then resecure the approved device. Non‑approved fasteners, seals or secondary closures are frequently cut when access is required, so any extra device should be sacrificial and inexpensive (for example, a numbered tamper‑evident cable tie) rather than a permanent metallic fastening that obstructs inspection.

Practical steps: secure the primary access with an approved device displaying the Travel Sentry logo or Safe Skies marking; add a disposable indicator (printed tie, paper seal, or adhesive tamper strip) outside the approved device if desired; keep detailed photos of contents and the bag’s condition before check‑in; pack valuables and critical items in a carry‑on to avoid risk of forced entry.

For international itineraries and non‑U.S. checkpoints, local screening authorities may not follow the same approval lists – research destination and transit country policies in advance. If an approved device is damaged or a secondary fastener is removed, file a report with the airline and keep receipts for replacements; note serial numbers for registered devices and manufacturer support options for master‑key re‑securing.

When choosing additional protection, prioritize tamper evidence and rapid replaceability over redundancy that blocks official inspection; this reduces the chance of a broken fastener, missing contents, or delayed travel processing.

Two-Point Security for Checked Suitcases at U.S. Airport Screening

Recommendation: Attach one screening-approved fastening device bearing the Travel Sentry or Safe Skies logo and add a tamper-evident strap or numbered seal instead of installing a second permanent closure that would block inspection.

Why this arrangement

Screening agents are authorized to open checked bags for inspection; non-certified secondary closures are commonly cut and discarded, often causing damage and replacement costs. Certified fastening devices allow authorized screeners to open and re-secure contents using a master access method, reducing the chance of forced entry and material loss.

Practical setup and handling

Use a Travel Sentry- or Safe Skies-marked fastening device on zipper pulls, pair it with a 2″ wide exterior strap that keeps seams compressed, and thread a brightly colored, single-use tamper seal or numbered cable tie through both zipper sliders and the strap’s loop. Place fragile or high-value items in carry-on or on-body storage – consider a waterproof waist pack for electronics and passports: best waterproof waist packs for jet skiing. If inspection occurs, request a written record from the screening agent and photograph any damage before leaving the facility for claims processing.

Dual securing policy for checked and carry-on bags

Recommendation: For checked baggage, use at least one fastener recognized by the Transportation Security Administration (Travel Sentry or Safe Skies); any additional non-recognized fastener will likely be cut if an inspection is required. For carry-on items, secondary fasteners are allowed but screening officers may request opening or remove the device at checkpoint.

Key rules

• Checked baggage: agents possess master access for recognized fasteners and will attempt non-destructive access first; if access cannot be achieved, non-recognized devices will be removed or severed.
• Multiple recognized fasteners: permitted – both can be opened by inspection personnel without damage if they carry the appropriate access tools.
• Non-recognized add-ons on checked pieces: treated as obstacles and are commonly cut to complete inspection, increasing risk of damage to zippers, straps or contents.
• Carry-on items: screening occurs at point of entry; sealed or secured carry-ons may be requested to be opened at the checkpoint rather than having devices cut.
• Tamper-evident seals and cable ties: cheap and acceptable for indicating interference, but will be removed if inspection is needed.

Practical recommendations

1. Fit a Transportation Security Administration–recognized fastener on any checked piece intended to remain locked; keep spare combination codes or key duplicates accessible.
2. If additional protection is desired, use a second fastener that also carries a recognized logo to avoid forced removal.
3. Avoid high-security aftermarket padlocks on checked baggage; these are common victims of cutting during inspection.
4. Keep high-value items and fragile gear in carry-on containers; consider a purpose-built daypack – see best backpack for fly fishing for examples of durable carry options that stay with the traveler.
5. Document contents with photos and inventories before travel; retain receipts for locked items to assist with any claims if damage occurs.

Using an approved security fastener with a secondary strap while allowing airport screening access

Attach an airport-screening-approved fastener to the zipper pulls and run the secondary strap around the case body so the strap does not pass through zipper heads or the fastener hasp; this ensures screening agents can access the compartment without cutting the secondary device.

Route guidance: place the strap below the zipper line or through the suitcase side handles, leaving at least 1.3 cm (½ inch) of exposed zipper-pull area and a visible gap to allow insertion of an inspection tool or key. Avoid threading the strap into any built-in locking channel or across the zipper teeth.

Choose compatible hardware: use a strap with a quick-release buckle or a breakaway section positioned on a side panel so an inspector can unbuckle or cut the breakaway without disturbing the approved fastener on the zippers. If using tamper-evident ties, select numbered cable ties and fasten them so they are easy to trim away while the approved fastener remains intact.

Checked-bag vs carry-on approach: for checked items assume screening staff may use agency access tools on the approved fastener; therefore the secondary strap must never block access to the approved fastener. For carry-on, prioritize quick-release features and avoid metal hardware that could be mistaken for prohibited items during handheld screening.

Pre-trip verification: secure the approved fastener, attach the secondary strap as planned, then perform these tests – unzip and rezip the compartment while the strap is in place; confirm the approved fastener remains reachable; try unbuckling or cutting the breakaway point without disturbing zipper alignment. Adjust routing until all operations work smoothly.

Tamper-evidence and records: photograph the arrangement, note serial numbers of any tamper ties, and place a discreet tag on the strap indicating “inspection access” so screening staff can identify which element should be opened or removed during an inspection.

Expect immediate cutting of nonstandard seals; document damage and report at the airline desk before leaving the terminal

Photograph exterior and interior damage (include bag tag and boarding pass), keep the inspection notice placed inside, and obtain an incident reference from screening staff. If a secondary seal or strap is severed, screening officers usually leave a printed “Baggage Inspection” slip; secure photos showing the slip next to the damaged fastener and all serial numbers or brand markings of the destroyed item.

What screening officers typically do during a forced-entry inspection

Officers open the case, inspect contents, remove prohibited items, and will cut or remove any device that blocks access. Repacking commonly occurs with a plastic tie or standard reseal; the original severed component is not generally reattached. An internal notice explaining the opening is placed inside most checked or stowed suitcases. The screening team may retain cut pieces for evidence, or hand them to the airline’s baggage office at the airport.

Step-by-step recovery process for severed fasteners and damaged gear

1) At the airport: present photos, boarding documentation and the inspection slip at the airline’s baggage service desk and request an incident report number. 2) Lost & found and security checkpoint property offices: file a query for retained cut pieces–provide the incident number and exact description (brand, color, serial). 3) Claims and reimbursement: save purchase receipts for replacement fasteners or straps; include receipts, photos, incident number and baggage tag when submitting a damage/loss claim to the carrier (use the carrier’s online form if off-site). 4) Evidence retention: keep the original bag and packaging until a claim is resolved; do not discard the inspection notice or photographic evidence. 5) If the destroyed item has sentimental or high monetary value, escalate to the airline’s customer-claims department and attach proof of value (appraisal, original invoice).

Practical tips: favor tamper-evident disposable ties as secondary tamper indicators (they signal interference without preventing access), record serial numbers for reusable security devices during packing, and replace destroyed components immediately with readily available parts from airport shops or online retailers.

Practical alternatives – tamper-evident seals, straps, and packing tips

Install one-time tamper-evident seals on zipper pulls and add a high-strength external strap with a combination buckle; pack valuables inside a carry-on with layered padding and photograph serial numbers before departure.

Application guidance

Use plastic pull-tight seals (single-use) on exterior zipper sliders and main compartment zippers; thread seals through both sliders or through a zipper hole and anchor point. For higher resilience, use steel cable seals meeting ISO 17712 for chain/bolt-style use on frames or removable wheels. Select adjustable straps with a tensile rating greater than 1,000 lbf (≈4,450 N) and a buckle that allows a visible tamper indicator (fray or staple-style damage). Place the strap across the case lengthwise so straps, seals and zippers form a visible system; avoid threading straps through airport inspection tags or interior access panels.

Inside the carry-on or checked case, separate fragile items with clothing, use zippered packing cubes to contain small valuables, and place electronics in a middle layer surrounded by soft goods. Keep passports, cash and spare batteries in an interior, zippered pouch that is itself sealed with a pull-tight tie or adhesive tamper tape.

Pre-travel checklist

1) Photograph content layouts and serial numbers for valuables; store copies in cloud and on phone. 2) Apply seals to primary zipper points and note serials in travel file. 3) Fit external strap tensioned snugly; mark strap with removable ID tag. 4) Place high-value items inside carry-on and pad with soft layers; keep originals of travel documents in an interior sealed pouch. 5) Pack a small kit of spare seals, cable ties and a marker for on-the-road resealing if necessary.
