Does tsa scan carry on luggage

What happens: Every bag you bring into the cabin passes through X‑ray or computed tomography equipment; checkpoints also use explosive trace swabs and may require manual inspection or a pat‑down when images or swabs flag an item. Expect electronics to be separated into bins at many checkpoints unless you hold PreCheck or the lane uses CT machines that allow electronics to remain inside.

Liquid rule and medications: Follow the 3‑1‑1 policy: containers no larger than 3.4 oz (100 ml), all containers fit inside a single quart‑size resealable clear bag, one bag per passenger. Medically necessary liquids larger than 3.4 oz are permitted but must be declared for screening and presented separately; carry prescriptions or a physician’s note when practical.

Batteries and devices: Spare lithium‑ion batteries must travel in the cabin with terminals protected (tape or original packaging). Batteries under 100 Wh are unrestricted in carry‑with-you items; batteries between 100–160 Wh require airline approval and are limited in number. Keep power banks and loose cells inside your personal item rather than packed inside checked bags.

Prohibited items and firearms: Firearms and ammunition are not permitted in the cabin. Firearms may be transported in checked baggage only if unloaded, locked in a hard‑sided case, and declared to the airline at check‑in; follow the carrier’s ammunition limits and secure packaging rules. Non‑folding knives, large blades, and many flammable aerosols are barred from the cabin; small scissors with blades under 4 inches are typically allowed.

Practical checklist before you reach the checkpoint: place liquids in a single clear quart bag, keep large electronics accessible for removal, stow spare batteries in your personal item, lock checked cases if transporting regulated items, print or have accessible any medical documentation, and arrive at least 2 hours before domestic departures and 3 hours for international flights. Enrolling in PreCheck speeds screening and often removes the need to remove shoes, laptops and light outerwear.

Airport Screening for Hand Baggage

Place electronics larger than a smartphone in an accessible compartment and pack all liquids in a single clear quart-sized bag with containers no larger than 3.4 fl oz (100 ml).

Checkpoint equipment typically includes X-ray imaging for cabin bags and metal detectors or millimeter-wave body imaging for passengers. Triggered alerts lead to a manual bag inspection; random explosive-trace tests are also possible.

Some security lanes use computed tomography (CT) machines that can allow certain devices to remain inside if items are stowed neatly and dense objects do not obscure contents. If asked, follow the officer’s instructions to remove specific items for separate screening.

Prohibited items in the cabin include firearms and firearm components, most large knives and fixed blades, explosives, and many types of flammable aerosols. Spare lithium-ion batteries must be kept in cabin bags with terminals insulated; batteries between 100 Wh and 160 Wh require airline approval, and batteries above 160 Wh are not permitted.

Pack sharp tools, sporting blades, and large quantities of aerosols in checked bags or leave them at home. Keep personal toiletries in the clear quart bag at the top of your cabin bag for quick removal. Have boarding pass and ID ready to speed throughput.

Security officers may temporarily retain or permanently confiscate items that violate rules; possession of weapons or explosive materials can result in fines or criminal charges. Secondary inspection increases processing time and may include additional questioning and bag searches.

Verify specific airline and airport restrictions before travel, and allow extra time–commonly two hours for domestic and three for international departures–if you prefer to avoid delays caused by secondary checks or item disputes.

Which onboard items commonly trigger additional screening or inspection?

Quick action: Place laptops, tablets, and other large devices in an easily accessible compartment and separate spare batteries and power banks into an outer pocket for immediate inspection.

Electronics: Laptops, tablets, large cameras, gaming consoles and some e-readers often prompt a closer look because they can obscure objects on X-ray images. Remove these from your cabin bags unless they fit in a laptop-friendly sleeve; using a purpose-built pack reduces handling – see best travel backpack for electronics for models with dedicated compartments.

Batteries & power banks: Spare lithium-ion batteries and power banks commonly trigger extra checks. Limits: up to 100 Wh are widely accepted in the cabin; 100–160 Wh require airline approval; >160 Wh are usually prohibited in both checked and onboard bags. Keep spares in original packaging or insulated against short circuits and present them separately when requested.

Liquids, aerosols and gels: Containers larger than 3.4 fl oz (100 mL) or amounts exceeding a single quart-size clear bag often lead to additional screening or disposal. Place all small containers in a transparent resealable bag and keep larger permitted medical or baby liquids with documentation ready for inspection.

Powders and granular substances: Powders over about 12 oz (350 mL) typically require separate inspection; common examples include protein powder, spices and baby formula. Transfer smaller amounts into clear containers and expect to remove them from your bag if asked.

Sharp, sporting and hobby items: Knives, longer scissors (blades over ~4 inches), multi-tools, baseball bats, ski poles and certain fishing gear are frequently flagged. If needed for travel, pack them in checked items or ship them ahead; briefcases or backpacks with concealed tools will almost always prompt a manual search.

Food and dense organic material: Dense foods (cheeses, large cakes, jars of preserves) and whole fruits/vegetables can obscure X-ray images and may be opened for inspection or swabbed. Pack perishable items in clear, leakproof containers and be ready to present receipts or ingredient lists if requested.

Medical devices and supplies: CPAP machines, nebulizers, insulin pens and syringes are permitted but commonly inspected. Carry physician letters and original packaging, remove devices from bags for X-ray where asked, and keep medications accessible to avoid delays.

Metal objects and clothing: Belts, shoes with heavy metal, bulky jewelry and coins can trigger alarms at screening portals and lead to pat-downs or bag checks. Wear slip-on shoes and minimal metal during screening to reduce secondary inspection rates.

Packing tips to reduce secondary checks: Use clear toiletry bags, dedicated electronics compartments, label medical supplies, isolate powders in small transparent containers, and keep spare batteries reachable. Organized packing speeds up inspection and lowers the chance personal items are opened for manual search.

How to pack liquids, gels, and aerosols to meet airport screening rules

Put all liquids, gels and aerosols into containers of 3.4 ounces (100 milliliters) or smaller and place them together in a single clear, resealable 1‑quart (≈1 L) plastic bag per passenger; present that bag separately at the screening area.

• Maximum container size: 3.4 oz / 100 mL for items transported in cabin baggage; larger containers must go in checked baggage or be discarded.
• Bag limit: one quart-sized clear resealable bag per traveler; multiple quart bags will typically be rejected during processing.
• Types covered: liquid toiletries (shampoo, conditioner), gels (toothpaste, hair gel), aerosol personal-care items (deodorant, hairspray) are subject to the same quantity and bag rules.

Exceptions and handling

• Medications: prescription and over-the-counter medications may exceed 3.4 oz. Keep them separate from the quart bag, carry prescriptions or pharmacy labels if available, and declare them to the screening officer.
• Baby items: formula, breast milk and baby food can be carried in quantities greater than 3.4 oz for the flight; keep them separate and declare them for inspection.
• Duty‑free purchases: keep items sealed in the tamper‑evident bag with the original receipt; present the sealed bag during screening to avoid secondary inspection.
• Hazardous aerosols: flammable or self‑defense sprays are restricted or prohibited in cabin carriage and may only be transported under specific hazardous‑materials rules in checked baggage.

Packing and preparation tips

1. Use leak‑proof travel bottles (3 oz/100 mL) with tight caps; wrap screw caps with tape or use bottles with built‑in locking caps to prevent spills.
2. Place the quart bag near the top of the bag or in an outer pocket so it can be removed quickly when requested for separate inspection.
3. Double‑bag creams and sunscreens or put fragile bottles in a small hard case to avoid leaks that trigger additional checks.
4. Consider solid alternatives (shampoo bars, solid deodorant, toothpaste tablets) which are not subject to the liquid‑bag limit and do not need to be removed for screening.
5. Label containers or keep original packaging for prescription liquids to speed up verification if an agent asks for proof.

If an item is larger than allowed and cannot be placed in checked baggage, expect it to be surrendered or disposed of at the screening point; declared medical and infant items are screened but are generally permitted in reasonable quantities after inspection.

Handling laptops, tablets and spare batteries at the checkpoint

Remove all laptops and tablets from bags and place them flat in a separate bin for X‑ray; keep chargers with the device bin and remove thick protective cases if requested. Power devices on quickly when asked – a device that cannot power up may be pulled for manual inspection or temporarily detained.

Keep spare lithium batteries with you in the cabin; do not pack spare cells or packs in checked baggage. Protect battery terminals by taping exposed contacts or using individual plastic pouches or original packaging to prevent short circuits. Place each spare battery in a separate pocket or pouch to avoid contact between terminals.

If you have batteries rated between 100 Wh and 160 Wh, obtain airline approval before arriving at the checkpoint and carry documentation showing the Wh rating (printed on the battery or manufacturer specification). Limit such batteries to two spares per passenger unless the airline’s policy states otherwise. Batteries above 160 Wh are prohibited in passenger aircraft.

When a security officer requests device removal from sleeves, comply immediately and handle the device only as instructed. Keep devices charged to at least a minimal level–officers commonly ask to power on to verify functionality. If a device is encrypted or locked, explain this to the officer; an officer may request a demonstration of power-up without requiring decryption.

Keep receipts or manufacturer labels showing Wh or lithium content when possible. For added protection of high‑value items or extended coverage options consult best umbrella insurance without auto.

How medications, medical devices, and baby supplies are processed at the security checkpoint

Keep prescription drugs, injectables, and baby feeding items in clearly labeled containers and present them for inspection before imaging; have prescriptions or a clinician’s note ready for syringes, controlled meds, and oxygen prescriptions.

Medications and injectables

Store pills and liquid medicines in original bottles with pharmacy labels when possible; small unlabeled pill vials should be avoided. Liquid medications exceeding 100 mL are permitted but must be declared at the checkpoint and will undergo additional inspection or testing. Insulin pens and vials, injectable medications and syringes are allowed with documentation; place syringes inside a puncture‑resistant container and separate from other items for visual inspection. If an officer requests an alternative to imaging, ask for a private inspection or swab testing rather than placing delicate medications through the X‑ray machine when manufacturer guidance advises against exposure.

Medical devices, mobility equipment, and baby supplies

Bring device identification cards and manufacturer instructions for implanted devices, pumps, CPAPs, portable oxygen concentrators and mobility chairs. Inform the officer at the start of screening so staff can offer an alternative inspection (visual check, hand inspection, or explosive trace swab) if the device cannot safely pass through the X‑ray. Spare lithium‑ion batteries for medical devices must remain in the cabin: batteries under 100 Wh are permitted without airline approval; batteries between 100–160 Wh require airline approval and are typically limited in number; batteries above 160 Wh are not allowed on passenger aircraft. Protect battery terminals (tape or original packaging) and carry each spare separately. Breast milk, formula, and baby food are exempt from standard small‑liquid limits but must be declared and will be tested; keep these items accessible, labeled, and, if possible, pre‑separated into clearly marked containers to speed inspection.

What to do if airport security opens your bag: procedures, documentation, passenger options

Immediately request a supervisor and obtain the printed inspection notice or receipt; photograph the opened bag, its contents, the inspection slip, and the checkpoint ID signage before leaving the area.

On-the-spot procedure

Ask the officer to provide their name, badge number and the agency phone number; request a private secondary screening room if you do not want the search in public. Remain with the bag during the inspection unless directed otherwise; do not touch or rearrange items until the officer documents them.

If any item is removed by security personnel, insist on a written receipt that lists removed items, the reason (if stated), date/time, and the name/ID of the removing officer. If personnel refuse a receipt, note names, time and location and take photos of the emptied bag and the area.

Documentation checklist to collect and save

Minimum data to record: inspection notice number (if issued), officer name/ID, supervisor name/ID (if called), exact date and time, checkpoint location, flight number, and baggage tag numbers (if applicable).

Evidence to capture: high-resolution photos of the opened bag and all contents, close-ups of damaged items, serial numbers, product receipts, warranty cards, and any packaging. Save boarding pass, bag tag and all receipts related to purchases of missing/damaged items.

For theft or significant damage, file a police report at the airport before leaving; get the report number and officer contact. For items removed and retained by security, request written justification and a chain-of-custody note showing where the items were taken.

Report missing or damaged property to the airline’s baggage service office for checked items and to the airport lost & found for items handled at the checkpoint. Provide copies of the inspection notice, photos, receipts and the police report number when available.

To seek redress from the screening authority, use the agency’s online complaint form and include the inspection notice number, photos, receipts, written timeline and contact information; keep copies of all submissions. For targeting or treatment concerns, consider filing through the Department of Homeland Security Traveler Redress Inquiry Program (TRIP) and attach the same documentation.

Escalation path: request on-site supervisor → contact airport security manager (ask for business card) → file agency complaint online → file airline property claim (for checked items) → local police report → civil claim/small-claims court if recovery fails. Retain originals and scanned copies of every document.

When claiming value, provide purchase receipts, serial numbers and proof of ownership; if receipts are unavailable, submit photos and contemporaneous proof such as product registration, warranty emails, credit-card statements or manufacturer account records.

If electronic devices are missing, report IMEI/serial numbers to the police and your carrier, disable or locate devices via manufacturer services, and preserve device serials for insurance or warranty claims.
