Perfume is generally allowed in hand carry luggage, as long as it adheres to the strict rules regarding liquids on flights. Transportation Security Administration (TSA) guidelines state that liquids in hand carry must be in containers of 3.4 ounces (100 milliliters) or less, and all containers must fit into a single clear, quart-sized plastic bag. This includes perfume bottles, which should be securely closed and placed in the plastic bag for easy inspection at the security checkpoint. It's important to note that individual airlines may have additional restrictions or guidelines, so it is advisable to consult their specific policies before traveling with perfume in your hand carry luggage.
