You can take perfume on a plane with the following size restrictions:
- Carry-on luggage: Perfume bottles must be 3.4 ounces (100 milliliters) or less per container. All liquid containers, including perfume, must fit comfortably in a single quart-sized, clear, plastic zip-top bag as part of the TSA's 3-1-1 liquids rule. You can bring multiple bottles as long as they fit in this bag and each is 100 ml or less
- Checked luggage: You can pack larger perfume bottles in checked baggage, but each container must not exceed 500 ml (16.9 ounces), and the total quantity of perfume should not exceed 2 kg (4.4 pounds). It is important to pack perfume securely to avoid spills or breakage
- Duty-free purchases: Perfumes bought at duty-free shops or onboard the aircraft do not count toward the 100 ml carry-on limit but must remain in their original sealed packaging with proof of purchase
In summary, for carry-on, the maximum perfume bottle size is 100 ml, and for checked bags, it can be up to 500 ml per container with a total limit of 2 kg. Always pack perfumes securely to prevent damage during travel.
