In 2026, the number of perfume bottles you can carry is not limited by count, but rather by the TSA's "3-1-1" rule for liquids. Every individual bottle must be 3.4 ounces (100 milliliters) or less in volume. You can carry as many as will comfortably fit into a single quart-sized, clear plastic, resealable bag. For the average traveler, this usually means 3 to 5 small bottles alongside other toiletries. It is important to note that the container size is what matters; a 5oz bottle that is only half-full will still be confiscated. If you wish to bring larger quantities, you can pack them in your checked luggage, where the FAA limits the total aggregate of all medicinal and toiletry articles (including perfume) to 2 liters (68 fl oz) per person, with no individual container exceeding 500ml (17 fl oz).
