Perfume and Cologne on a Plane: TSA and FAA Limits

Where these numbers come from

Perfume and cologne are toiletries, and TSA allows them in both bags. The difference is the size cap: 3.4 ounces (100 milliliters) per bottle in carry-on, and 18 ounces (500 ml) per bottle in checked baggage. The TSA item page also notes that your final clearance is at the discretion of the officer at the checkpoint.

Two limits sit on top of each other for checked bags. Each container is capped at 18 ounces or 500 ml, and the combined total of toiletries and medicines is capped at 70 ounces (2 kg or 2 liters) per passenger. Six 3.4-ounce perfume bottles total 20.4 ounces, which is inside both limits. A traveler bringing twelve 8-ounce gift sets would need to split them with a companion.

Many fragrances are alcohol-based and flammable. FAA allows them under the toiletry exception because they are applied to the body. Aerosol perfume sprays need a cap to prevent accidental release. Fragrance sprays that contain extra propellant can trigger extra checks. Keep caps on and wrap the bottles in clothing to reduce the risk of breakage.

Duty-free fragrance is the most common big-bottle question. A 6.7-ounce bottle bought abroad may come with you in carry-on on a connecting flight to the US, but only sealed in the retailer's tamper-evident bag with the receipt, dated within 48 hours. Open the bag early and the bottle is treated as an ordinary oversize liquid. The liquids rule page covers the exception.

Solid perfumes, balms and scented sticks avoid the liquid rules altogether. They are a sound choice for a carry-on-only trip. Just keep the tin closed to avoid leaks in a warm cabin, and stash it in your pocket where you can reach it.

If you must bring a larger bottle, check it in a hard-sided case. Sibling toiletry pages include hair spray and deodorant, which follow similar aerosol limits. A quick comparison shows why people decant. A 100 ml designer bottle is the cap for carry-on, but the box it ships in is bulkier than the bottle. A 10 ml atomizer holds about 100 sprays, enough for a two-week trip, and leaves most of your quart bag free for other items. Glass bottles can also break in a checked bag, so wrap them in clothing and set them in the middle of the suitcase.
