Travelers Should Rethink Packing Peanut Butter for Flights

When planning your next flight, reviewing what you pack can save you hassle at airport security. The Transportation Security Administration (TSA) is reminding passengers that peanut butter is classified as a liquid under their rules.

Recently, the TSA shared on X the clarification that peanut butter counts as a liquid, alongside a screenshot from Google AI Overview. It explains the reasoning behind considering peanut butter a liquid: it conforms to the shape of its container.

According to TSA guidelines, liquids, gels, and aerosols in carry-on luggage must be in containers of 3.4 ounces or less. These items must also fit inside a quart-sized bag. Larger quantities are permitted in checked baggage.

“You can’t bring peanut butter, [as] the TSA considers that to be a liquid because it conforms to the shape of its container rather than retaining its shape on its own,” stated Gary Leff, a travel industry expert.

However, there are ways to bring food through security. Eating before heading to the airport or packing foods allowed by TSA rules can be a smart choice due to costly and limited airport dining options.

Debates about the classification have emerged online. Some suggest making sandwiches beforehand to include peanut butter while traveling.

In previous instances, TSA has advised unique ideas for airports, such as bringing hammocks during long layovers, although rules may differ by location.

These suggestions have divided travelers, with some finding them disruptive in packed terminals while others appreciate the comfort during long waits.
