No, body butter is not considered a liquid when flying. According to Transportation Security Administration (TSA) guidelines, body butter falls under the category of a solid or semi-solid item, similar to creams and lotions. These types of products are not subject to the liquid restrictions imposed on items such as gels, liquids, and aerosols. However, it's always a good idea to check with your airline or the TSA website for the most up-to-date information on what is allowed in your carry-on luggage.
