Rule: containers of scented liquids, colognes or eau de toilette sized at ≤100 ml (≤3.4 fl oz) are permitted in carry-on bags if all such containers fit inside a single transparent, resealable plastic bag with a maximum capacity of 1 litre (quart-sized). Only one transparent bag is accepted per passenger; present it separately at security screening.
Items larger than 100 ml must be placed in checked baggage or acquired as duty-free in a sealed tamper-evident bag (STEB) with a dated receipt – retention of the sealed bag and proof of purchase is required to take larger bottles through checkpoints on most international routes. Medical liquids and infant food receive exemptions when accompanied by supporting documents or receipts.
Aerosol-format fragrances are subject to additional restrictions due to flammability and pressure limits; many carriers limit pressurised sprays or require smaller personal-use volumes. Consult the airline’s dangerous-goods guidance before travel and, when in doubt, move extra bottles to checked baggage to avoid confiscation.
Packing tips: secure caps, place bottles in zip-locks or padded pouches to prevent leaks, keep receipts for duty-free purchases, and store bottles upright inside the cabin bag. Confirm the departure and transit airports’ security pages prior to departure to align with local enforcement nuances.
Permitted perfume quantities under the 100 ml / 3-1-1 liquid rule
Pack fragrance bottles no larger than 100 ml (3.4 fl oz) each and place all such containers in one transparent, resealable 1-litre (approx. 1 quart) plastic bag; security permits one bag per passenger.
Container limits and examples
Each individual container must be labeled with volume ≤100 ml. Typical allowed combinations: one 100 ml bottle; two 50 ml bottles; several small vials that physically fit inside the 1-litre bag. A single 125 ml or 250 ml bottle is not acceptable inside the clear bag and will be confiscated unless moved to checked baggage. Liquids, gels, creams and aerosols are all treated under the same volumetric rule.
Duty-free purchases, aerosols and practical tips
Duty-free items over 100 ml are normally accepted in the cabin only if presented in a tamper-evident security bag (SEB) with an accompanying receipt showing date of purchase; seal and receipt must remain intact for transfer through security and while in transit. Aerosol fragrances count as liquids and must meet the ≤100 ml requirement; some airlines restrict flammable aerosols in checked baggage, so verify carrier rules before packing. Decant larger bottles into labeled travel-size containers (use a syringe or measuring cup for accuracy), keep the resealable bag accessible for inspection, and move excess volumes to checked baggage to avoid seizure at screening.
Packing methods to prevent spills and pressure leaks in cabin baggage
Pack fragrances upright, double-sealed and cushioned in the centre of the carry-on to reduce pressure-driven seepage and impact damage.
Use clear resealable plastic bags of 4 mil (≈0.10 mm) thickness or thicker; place each bottle in its own bag, expel excess air, seal, then place that bag inside a second sealed bag for redundancy.
Wrap glass bottles in 8–12 mm bubble wrap (2–3 full layers) or in folded microfiber cloths; secure with waterproof tape around the cap and shoulder area only, avoiding tape contact with spray nozzles.
Leave a headspace of roughly 8–12% of total bottle volume when decanting into travel atomizers (e.g., fill to ~88–92% full). Reduced fill avoids liquid displacement during climb/descent pressure changes.
Prefer non-pressurized pump or travel atomizers with locking caps. If using screw caps, add a single square of cling film between neck and cap before tightening, then tape the cap seam with a 2–3 cm strip of packing tape.
Place bottles inside a small rigid case (plastic sunglass case or dedicated hard travel vial case) to prevent point impacts; fit the case into the bag core surrounded by soft garments to absorb shocks.
Perform a leak test before packing: invert and compress each sealed container over a towel for 30 seconds; inspect sealed bags for wet spots and repeat sealing method if any residue appears.
Avoid exterior pockets and upright-only compartments; stow fragrances centrally and horizontally if rigid cases are used, ensuring they cannot shift during transit.
Carry a folded absorbent cloth and one spare resealable bag in the same compartment for emergency containment of a slow leak discovered during flight.
Airport security checks: declaring fragrances and possible confiscation
Declare duty-free fragrances at the security checkpoint and present the sealed tamper-evident bag (STEB) together with the original receipt for inspection.
When declaration is required
Declare items purchased after passport control, especially when passing through secondary screening or during international connections. Goods in a valid STEB with matching receipt are usually accepted, but transfers into jurisdictions with stricter screening (United States, United Kingdom, some Asia–Pacific hubs) may trigger additional checks even if sealed.
Declare any containers that are open, leaking, or clearly over permitted carry-on liquid allowances prior to screening. Security personnel will flag such items for immediate surrender; bottles without tamper evidence are frequently removed.
If an item is seized
Request a written confiscation notice and retain the purchase receipt. If seizure occurs before gate access, ask whether the item can be placed into checked baggage at a transfer or airline desk; once past the screening point, recovery is unlikely. Some airports provide on-site shipping or left-baggage services – confirm availability at the terminal.
Follow up with the airport security office and the retailer for refund or retrieval options; appeal routes are limited and vary by country. For precise rules and complaint procedures consult the relevant national aviation security authority (TSA for the United States, CAA for the United Kingdom, or the local civil aviation authority).
Alternatives when a fragrance exceeds cabin limits (shipping, samples, wrapping)
Ship the full-size bottle ahead via a courier that accepts alcohol-based cosmetics; decant one or two travel atomizers (≤100 ml) as cabin-approved backups.
Shipping ahead – practical checklist
- Verify alcohol percentage on the label or Safety Data Sheet (SDS). Ethanol concentration ≥70% is commonly treated as flammable; contact carriers for exact acceptance rules.
- Prefer surface/ground transport where possible: many air services restrict flammable liquids or require special dangerous-goods handling.
- Select a carrier that explicitly accepts cosmetic flammables, request tracked insured service with signature-on-delivery; typical price range: domestic USD 10–40, international USD 30–150 depending on weight and speed.
- Packing protocol: tighten cap, apply PTFE/Teflon tape to threads, wrap bottle in absorbent material (paper towels), place in a sealed 1L plastic bag, add 3 layers of bubble wrap, then a small rigid inner box and an outer corrugated box with ≥5 cm cushioning on all sides.
- Declare contents per carrier requirements, retain tracking number and proof of value for customs or claims.
Decants, samples, duty-free and on-site purchase
- Travel atomizer sizes: 5 ml, 10 ml, 15 ml, 30 ml. Transfer with a syringe or pipette; leave 1–2 cm headspace to accommodate pressure changes during transit.
- Independent decant services commonly charge approximately USD 5–15 per 5–10 ml sample; retail travel sprays range roughly USD 10–40 depending on brand.
- Duty-free purchases delivered in sealed tamper-evident bags with receipt are generally allowed through security on the same itinerary–keep bag sealed and receipt accessible.
- Ordering to destination address or hotel removes transport restrictions and paperwork; arrange delivery window and recipient name to avoid lost parcels.
Packing tips for checked carriage or shipping: place the boxed bottle inside a rigid travel case and surround with soft items; for rugged solutions consult best luggage for soldiers. Avoid leaving packages in hot vehicles or trunks–heat accelerates evaporation and pressure buildup.

Quick final checklist: SDS/alcohol %, carrier acceptance confirmed, triple-layer leak protection, insured tracked shipment, travel-sized decants ready, receipts and documentation accessible for customs.
