Does the airport go through your checked luggage

Immediate advice: keep valuables, medications and spare batteries in cabin bags; lock suitcases with agency-approved locks that permit security access (for travel to/from the United States use TSA-approved locks); include a printed inventory and contact details inside each case and photograph packed contents before handing them over.

For data: in the United States Transportation Security Administration screens 100% of hold baggage destined for passenger aircraft using Explosives Detection Systems (EDS); alarms or suspicious images trigger manual inspection, explosives-trace testing and K9 teams. Many other states mandate hold-bag screening as well, though methods vary (in-line EDS, off-site screening, risk-based sampling). If a bag flags, staff will open and inspect, then reseal or tag it.

Packing recommendations: remove spare lithium batteries and place them in carry-on only; put passports, cash, high-value electronics and prescription drugs in hand baggage; for firearms follow airline and national rules – declare at check-in, present unloaded and locked in an approved hard case; keep ammunition packaged per carrier guidance. Avoid packing flammable liquids, large quantities of aerosols or prohibited sharp objects in hold bags.

If an inspection occurs agents normally attach an inspection tag or tape; photograph the resealed case and its tag before leaving the terminal. If items are missing or damaged, file a written claim with the carrier immediately and keep boarding pass, tags and photos. For high-value contents consider a separate travel insurance policy that covers checked-bag loss or damage.

Why and when security personnel will open a passenger’s hold baggage

If screening equipment flags an item, request, or declaration, expect security staff to open a hold bag for manual inspection.

Common triggers for manual inspection

Alarm from X-ray or CT scanning; dense or ambiguous masses that obscure identifiable shapes; overlapping metal that mimics prohibited items; canine alert; visible liquids above allowed volumes; undeclared firearms or ammunition; loose spare lithium batteries; strong chemical or fuel odors; suspicious packaging such as tampered seals or multiple concentric wraps; intelligence-led or airline tip-offs; customs or immigration holds; and random compliance sampling by regulators.

What happens during inspection and how to respond

Authorized officers will unzip or cut open bag, perform hands-on examination, swab suspect residues for field testing, remove items that pose safety or customs risks, reseal bag with tamper-evident tape, and leave an inspection notice detailing agency contact and reason code. If fragile or high-value items are present, ask for presence of passenger or carrier representative and show serial numbers or purchase receipts to speed resolution. Declare firearms at check-in and store ammunition in approved containers; keep spare batteries and electronic cigarettes in hand baggage to avoid confiscation.

To minimize chances of manual opening: separate dense items into clear plastic bags, place toiletries in single, labeled container, stow electronics with minimal surrounding clutter, photograph contents before drop-off, use approved locks where allowed, label valuables with contact details, and carry prescriptions and critical documents in hand baggage.

Items most likely to trigger a manual inspection

Pack smart: place spare lithium batteries and power banks in carry-on; tape terminals and carry manufacturer documentation for batteries rated above 100 Wh.

Electronics and battery-powered devices: laptops, tablets, cameras with lithium-ion cells often produce dense X-ray signatures; security commonly opens bags when batteries appear loose, damaged, or stored inside unmarked cases.

Spare batteries and power banks: spare lithium-ion cells normally forbidden in hold baggage and must travel in carry-on; cells above 100 Wh require airline approval and original packaging.

Powders and granular materials: bulk powders (≥350 ml / 12 oz), protein powders, powdered baby formula, spices, and soil samples frequently cause alarms; keep powders in original labeled containers and separate into clear bags for quicker verification.

Unlabeled liquids, aerosols, flammable substances: fuel, lighter fluid, paint thinners, pressurized aerosol cans and peroxide-based cleaners often trigger manual checks or interdiction; ship flammable goods via approved carrier or obtain airline permission before packing in hold bag.

Sharp tools, knives, metal hardware: loose screwdrivers, wrenches, boxed blades, and concealed knives prompt inspections; sheath blades, fasten tools together, and list heavy metal parts on itemized inventory placed near bag opening.

Sporting equipment and large metal assemblies: golf clubs, baseball bats, tripods, work light stands and heavy umbrella stands produce complex X-ray shadows; consider transporting oversized metal items in specialized cases or shipping them separately. Example for stands and heavy bases: best outdoor umbrella stand with wheels

Unlabeled medical supplies and prescription drugs: injectable medications, syringes, oxygen concentrators, and mesh dressings can prompt manual inspection; carry prescriptions, physician letter, and original packaging to speed verification.

Miscellaneous triggers: mismatched weight vs declared contents, dense clusters of metal inside soft fabric, unopened packages from unknown vendors, and items wrapped in excessive tape increase likelihood of an officer opening hold bag; use clear packing lists and minimal opaque wrapping.

If inspection occurs, cooperate, present documentation, and use TSA-approved locks to avoid forced entry damage.

How to pack to minimize chance of bag search

Pack items for quick visual review: Place electronics, toiletry bottles over 100 ml equivalents, and chargers in a single top-access pocket so screeners can scan without opening main compartment.

Use clear, resealable plastic pouches for liquids; group similar items together; keep medication in labeled pillbox or original packaging to avoid manual check.

Limit loose items: Loose tools, cords, shoes increase chance of hands-on inspection. Use packing cubes or zip organizers to keep small items contained and visible on X-ray images.

Choose bag with dedicated front panel and quick-access pockets; example pack: best backpack for the camino for models that allow inspection without unpacking.

Remove strong odors from clothing and fabric; pet urine or smoke can trigger search. For fence- or outdoor-related pet stains consult how to clean dog urine from wooden fence then launder textiles before departure.

Use TSA-approved locks, clear ID tags, and a packing list inside bag. Labeling speeds up verification and reduces chance of sealed-bag forced opening.

Keep valuables and irreplaceables in carry-on. If placement inside hold bag needed, place near top and in clearly marked pouch to reduce hands-on rummaging.

How airlines and terminal operators notify passengers if bags were opened

Inspect seal, tag and external fasteners immediately after reclaiming a hold bag; if a paper inspection notice, broken lock or reseal tape is present, report condition to airline baggage office before leaving terminal.

Common notification methods

Paper slip placed inside near contents stating reason for manual inspection (security, customs, random); external sticker on handle or strap marked “Inspected” or “Security screened”; reseal with clear tamper-evident tape or carrier-branded security strap bearing agency code; handwritten or printed tag attached to carry handle with inspector ID and date; entry of inspection event into carrier baggage-tracing system with a PIR/reference number; SMS or email alert from carrier with inspection note and claim reference for incidents requiring follow-up.

Immediate actions and documentation

Photograph exterior and interior showing inspection notice, reseal material and any damage; keep inspection slip and reseal material until claim closed; obtain written report and reference number from airline baggage office and copy contact details for follow-up; prepare list of missing or damaged items with receipts and serial numbers; file carrier claim online using provided reference within carrier’s stated deadlines (many carriers request damage reports within 7 days and missing-item reports within 21 days); if theft suspected, obtain police report and include report number in carrier claim; retain boarding pass, bag tag and baggage claim receipt until resolution.

What to do if hold baggage is damaged, opened, or items are missing

Inspect bag at the carousel before leaving arrivals; if damage, tampering, or missing items are detected, report immediately at the carrier’s baggage office and obtain a written Property Irregularity Report (PIR) and reference number.

1. Immediate evidence collection

   • Photograph exterior, interior, contents, tag number and boarding pass; include a timestamp or use phone metadata.
   • Preserve broken components, packing materials and any suspicious debris; do not discard until instructed by carrier or police.
   • List missing items with brand, model, serial numbers, purchase dates and approximate value.

2. Reporting and paperwork

   • File PIR at carrier desk in arrivals hall; obtain printed copy, reference number and contact name.
   • If theft suspected, file a police report at terminal or local station and attach a copy to the PIR.
   • If departure from arrivals already occurred, submit a written claim to carrier within 7 days for damage/pilferage; for delayed baggage that later appears, file loss/damage claim within 21 days of receipt.

3. Documentation to include with any claim

   • Boarding pass, baggage tag, PIR copy, police report (if any).
   • Photos, itemized list of missing/damaged items, original purchase receipts or reasonable valuations.
   • Repair estimates from recognized repairers when seeking reimbursement for broken items or case repair.

4. Compensation, limits and carrier options

   • Carrier may offer repair, reimbursement or declared-value compensation; request written explanation of chosen remedy.
   • International liability often governed by Montreal Convention (limit approx. 1,288 SDRs – roughly US$1,700–1,900 depending on exchange rate); check contract of carriage for exact limits on specific carrier.

5. Insurance and payment routes

   • File parallel claim with travel insurer and/or credit-card benefits department; submit identical documentation and PIR reference.
   • Keep originals and send copies only; use registered mail or tracked email for claims and keep proof of submission.

6. Follow-up and escalation

   • Record all contact: dates, names, emails, phone numbers and promised deadlines. If no substantive reply within 14–30 days, escalate to carrier complaints department.
   • If carrier denies or offers inadequate settlement, escalate to national civil aviation authority, consumer protection agency or small-claims court; include full dossier (PIR, photos, receipts, police report, correspondence).

7. Practical tips to strengthen a claim

   • Register high-value items with carrier before travel when possible; carry receipts and serial numbers in carry-on or cloud storage.
   • When filing repair claims, obtain quotes from authorized service centers to avoid lowball estimates.
   • Use clear, concise language in claim letters: flight number, date, baggage tag, PIR number, itemized losses, requested compensation amount and bank/payment details.

Keep copies of every document until final settlement and payment are received.

How screening differs from customs search on international travel

Declare cash over 10,000 USD (or equivalent) and carry receipts for purchases and prescription medications; keep documents in an accessible pocket for inspection at arrival.

Authority and objective

Pre-boarding security screening focuses exclusively on aviation safety: detecting weapons, explosives and other immediate threats using X-ray machines, metal detectors, body scanners and explosive trace detection. Border customs inspections aim at fiscal control, import/export prohibitions, biosecurity and enforcement of trade laws; powers include seizure of undeclared or restricted goods, assessment of duties, fines and criminal referral. Security staff act under civil aviation regulations; customs officers operate under customs, tax and quarantine statutes and typically have broader authority at ports of entry.

Process, methods and likely outcomes

Security checks are usually administrative and preventive: prohibited items are removed and passengers may be denied boarding. Customs examinations are investigative and regulatory: baggage and personal effects can be opened, transported currency counted, electronic devices examined in some jurisdictions, and goods detained or seized. Physical searches, canine teams, laboratory testing (for drugs or agricultural matter) and documentary audits are common tools used by customs. Refusal to declare regulated items or large sums of money commonly results in fines, seizure or detention; cooperation and accurate declarations reduce escalation.

Practical steps: keep high-value purchases and prescription medication in carry-on or on-person with invoices and prescriptions; place food, plants and animal products in original packaging and declare them; photograph packed contents before departure; learn arrival-country allowance limits and prohibited-item lists online; if goods are seized request a written seizure notice and receipt, note officer badge numbers and retain copies of all forms for follow-up.
