Can I take perfume on a plane?

Perfume is screened as a liquid; cabin limits depend on the departure airport. Duty-free perfume bought airside travels in a tamper-evident STEB bag with the receipt visible.

At a 100ml checkpoint, each container 100ml / 3.4oz or smaller, in one clear liquids bag (quart-size at US checkpoints, usually 1L elsewhere). Some airports allow more — check your departure airport. Most 30ml/50ml travel perfumes are fine.

Full bottles can go in checked baggage. Wrap glass bottles. Perfume is a toiletry, not a drink, so the alcoholic-beverage rules don't apply. On flights covered by US FAA rules, medicinal and toiletry articles (including perfume, hairspray and alcohol-based products) are limited to 0.5kg / 500ml per item and 2kg / 2L in total per person, and aerosol release valves must be protected, for example by a cap. Other regulators and airlines may set their own limits.
