For travelers in 2026, the amount of perfume you can pack in your checked luggage is governed by both airline safety regulations and international hazardous materials rules. Because perfume contains alcohol, it is classified as a "medicinal or toiletry article." According to FAA and TSA guidelines, the total aggregate quantity of all such restricted liquids (including perfumes, colognes, and aerosols) per person cannot exceed 2 kg (70 ounces) or 2 L (68 fluid ounces). Furthermore, the capacity of any single container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces). This means you can typically pack several standard bottles of perfume without issue, provided they are securely capped to prevent accidental leakage. It is highly recommended to wrap glass perfume bottles in bubble wrap or place them inside a sealed plastic bag to protect your clothing in case of breakage due to pressure changes or rough handling. While there is no limit on the number of bottles, the total volume across all your toiletries must remain under the 2-liter limit to avoid being flagged during security screening of the cargo hold.
