Short answer: small bottles are permitted – each container must be 100 mL (3.4 fl oz) or smaller and all containers must fit inside one clear quart-sized resealable plastic bag; larger bottles belong in checked baggage.
TSA applies the 3-1-1 rule for departures from U.S. airports: 3.4 fl oz / 100 mL maximum per container, 1 quart-sized bag per passenger, 1 bag presented for screening. Keep units capped and inside the clear bag; items exceeding the volume limit will be refused at the checkpoint unless transferred to checked baggage.
Items bought at airport duty-free counters are allowed through security only if placed in a sealed tamper-evident bag (STEB) with the receipt visible. For connections into the U.S., maintain the sealed bag and receipt; international transfer rules vary, so check both airports’ security requirements ahead of travel.
Practical recommendations: decant fragrances into travel-size atomizers labeled ≤100 mL; choose solid scent sticks to avoid liquid limits; retain duty-free receipts; declare any medically necessary liquid at screening. For full-size bottles, pack them in checked baggage and verify your carrier’s hazardous-material limits because many scents are classified as flammable.
Fragrance in carry-on on UA (U.S.) – direct answer
Short answer: Small bottles of scented liquid are allowed in cabin baggage on UA-operated U.S. flights when they meet TSA 3-1-1: each container ≤3.4 fl oz (100 ml) and all containers fit inside a single quart-size (≈1 L) clear resealable plastic bag, one bag per passenger.
Specifics and screening
Definition: sprays, colognes and alcohol-based scent liquids are treated as liquids/gels and must follow the 3-1-1 rule at checkpoint. If an item is larger than 3.4 fl oz (100 ml) it will be refused for cabin carriage unless purchased duty-free and sealed in a tamper-evident bag with receipt (SED) – keep the sealed bag and receipt for connections. Medications, baby formula and breast milk are exempt from the 100 ml limit but must be declared and screened separately.
Packing tips and checked-bag limits
For checked bags, larger bottles are usually allowed but pressurized aerosols and flammable liquids have quantity and packaging limits under hazardous-materials rules; common practice limits total aerosol toiletries per passenger and requires protective packing. To reduce leakage risk: double-bag bottles, wrap caps with tape, place in the center of the suitcase surrounded by clothes. Always verify current UA hazmat policy and TSA rules before travel.

TSA 3-1-1 rule: maximum bottle size and bag requirements for fragrances
Limit each fragrance container to 3.4 fl oz (100 ml) or less and place all containers inside a single clear, quart-sized (≈0.95 L) resealable plastic bag; one such bag only per passenger and present it separately during security screening.
Breakdown of 3-1-1: 3 = each bottle ≤3.4 fl oz / 100 ml; 1 = one clear quart-sized resealable bag; 1 = one bag allowed per passenger. Containers exceeding 100 ml will be rejected at the checkpoint unless checked in the aircraft hold.
Duty-free purchases that exceed 100 ml are acceptable if sealed in a Secure Tamper-Evident Bag (STEB) with the original receipt. Keep the STEB sealed until reaching your final destination; if you must re-clear U.S. security, larger items in an unsealed STEB will likely be prohibited from cabin carriage and should be transferred to checked baggage.
Spray and aerosol fragrances are treated as liquids for screening and must follow the same 3.4 fl oz limit for cabin carriage. For sizes above that limit, use checked baggage, bearing in mind airline and hazardous-material restrictions on flammable aerosols.
Practical tips: decant into certified 100 ml travel bottles or atomizers, label contents, avoid overfilling, use a durable resealable quart bag, keep duty-free receipts with the sealed bag, and remove the bag from your carry-on at the checkpoint to speed inspection.
Packing duty‑free fragrances: when a sealed bag lets you carry larger volumes
Place duty‑free fragrances into the tamper‑evident security bag (STEB) at purchase, tuck the original receipt inside the sealed pouch and keep the seal intact until after the next security checkpoint – this is the standard way to move bottles larger than 100 ml (3.4 fl oz) in cabin baggage.
Most security regimes enforce a 100 ml / 3.4 fl oz per-container limit for liquids, but items bought in secure zones or onboard aircraft and packed into an STEB with receipt are typically exempt from that limit. STEB rules vary by airport and airline, so verify the transit-country and carrier policy before travel; if transfers include a domestic screening where different rules apply, expect stricter enforcement.
Practical checklist
– Keep the purchase receipt inside the sealed bag and ensure the bag’s tamper tape is unbroken.
– Present the sealed bag separately at security screening; place it in an outer compartment for easy inspection.
– Note bottle sizes and pack fragile bottles upright or cushioned to prevent leaks inside the STEB.
– If a flight includes a security re‑screening that requires opening the bag, move larger bottles to checked baggage to avoid seizure.
Risks and packing alternatives
Some airports or connecting routes reject STEB exemptions despite compliant packaging; when a large or high‑value bottle is at risk, move it to checked baggage inside a hard case or padded toiletry cube. For robust checked options see best luggage for moving overseas.
Carry‑on vs checked baggage: when to check an expensive or oversized fragrance
Keep high‑value scents in the cabin whenever regulations and routing permit; if size or transfer rules force placement in checked baggage, decant, insure and pack for impact and leak protection before handing off to the hold.
Decision checklist
- Size and screening: if original bottle exceeds cabin-allowed volume or cannot remain in a sealed duty‑free bag through connections, plan for checked transport or decanting.
- Value and replaceability: rare, limited‑edition or vintage bottles – avoid placing in the hold unless shipping with declared insurance.
- Fragility and packaging: heavy glass stoppers, decorative caps and collectors’ boxes increase breakage risk in checked compartments.
- Connections and transfers: multiple transfers increase probability of parcel mishandling; keep precious items with you on direct itineraries when feasible.
Packing protocol for the hold
- Decant option first: transfer part of the juice into 5–30 ml metal or PET atomizers and carry smaller vials in the cabin; store the full bottle in checked only if necessary.
- Sealing and containment: place bottle in its original box, wrap in bubble wrap, then double‑bag with heavy zip‑top bags to contain leaks.
- Placement inside suitcase: embed wrapped bottle in the center of a hard‑shell case surrounded by soft clothes; avoid pockets near edges or wheels.
- Labeling and locks: use TSA‑approved locks on zippers and mark the case “fragile” for gentler handling (this does not guarantee care).
- Documentation and proof of value: photograph bottle, serial number and receipt; store digital copies in cloud and paper copy inside a separate compartment.
- Insurance and alternatives: add declared value to checked baggage coverage or use a courier with insurance for very expensive items; consider shipping via insured, tracked service instead of checking.
- After arrival: inspect immediately; for transit damage or case harm, keep damaged packaging and photos for claims and consult local repair services such as best luggage repair dallas.
Quick checklist before travel: carry small decants in cabin if possible, photograph + keep receipt, double‑bag + cushion for the hold, insure or ship high‑value bottles separately.
Leak‑proof packing techniques for fragrance bottles in cabin bags
Seal the cap threads with 2–3 layers of cling film, wrap 5–7 turns of PTFE (Teflon) tape over the threads, fasten a 1″ strip of electrical or gaffer tape across the cap, then place the bottle upright inside a heavy‑duty resealable bag cushioned with bubble wrap.
Materials & small tools
Recommended items: cling film, PTFE/Teflon tape, electrical or gaffer tape (1″ width), small bubble‑wrap pouch or neoprene sleeve, heavy‑duty zip resealable bag (thick plastic), silica gel packet, spill‑absorbing pad or folded paper towel, lockable travel atomizer or decant vial for transfers, marker for labeling.
Step‑by‑step packing method
1) Test closure: press the spray once over a sink to confirm no immediate leak. 2) Apply cling film directly over the cap and screw ring; smooth tightly to remove air pockets. 3) Wrap PTFE tape around the bottle neck threads to create a secondary seal; overlap tape edges to cover any gaps. 4) Add a band of tape across the cap top to prevent unscrewing during transit. 5) Insert into a padded pouch; surround the base and sides with bubble wrap and secure with a small strip of tape. 6) Place the padded pouch upright inside the resealable bag together with a silica packet and an absorbent pad folded beneath the bottle. 7) Position the sealed bag in the center of the cabin bag, between folded garments, away from zipper seams and external impact zones.
For travel with glass or full‑size bottles, decant a working amount into a lockable travel atomizer and store the full bottle at checked storage or at destination. Perform a pressure test by sealing the packed bottle and gently squeezing the bag; any sign of wetness signals the need for re‑sealing or switching to a decant vial.
What to expect at security: screening, confiscation, and how to request a second inspection
Keep scent bottles accessible in a clear quart-size resealable bag and present them separately in the bin; expect X‑ray screening, possible explosive‑trace detection (ETD) swabs, and manual inspection if an item looks suspicious on the monitor.
Typical screening sequence: X‑ray first; if an anomaly appears officers may remove the item for closer X‑ray, open packaging for visual inspection, swab for ETD, or send the item for hand inspection. Sniffer dogs or secondary screening lanes may be used randomly or when the alarm indicates a chemical/organic residue.
Most common seizure causes: containers larger than allowed for carry‑on limits, leaking bottles, unlabeled or unidentifiable liquids, and products with very high alcohol content. Alcohol above 70% by volume (140 proof) is treated as hazardous and is generally prohibited in both cabin and checked stowage; such items are routinely surrendered.
If an agent says an item must be surrendered, request a supervisor before disposal. Ask for a written receipt or confiscation notice at the checkpoint, note the officer’s name and time, photograph the item and its packaging, and keep boarding pass and ID until you receive documentation. Use tsa.gov/contact for follow‑up; TSA Contact Center: 1‑866‑289‑9673 and @AskTSA for non‑urgent questions.
To request a second inspection: state calmly, “I would like a secondary screening and to speak with a supervisor,” present purchase receipts or original retail packaging, and offer to open boxes yourself to speed examination. Do not obstruct screening; refusing may result in denial of boarding or escalation to local law enforcement.
If an item is seized without a receipt or you dispute the decision, file a complaint through tsa.gov/contact and retain any evidence (photos, witness names). For items turned over to airport police, contact the airport’s lost & found/property unit for recovery procedures and record‑keeping instructions.
