Yes, you can absolutely put sanitary pads, tampons, and other menstrual products in your carry-on bag. There are no TSA or international airline restrictions on these items, as they are considered solid personal hygiene products rather than liquids or gels. You can pack as many as you need for your journey, and they do not need to be placed in a clear plastic bag or declared at security. In fact, it is highly recommended to keep a small supply in your carry-on in case of flight delays or unexpected cycle starts while in the air. In 2026, many frequent travelers use a dedicated "period pouch" or small organizer to keep these items clean, discreet, and easy to find within a larger backpack or tote. Most modern airports also now provide free or low-cost menstrual products in the restrooms, but having your own preferred brand on hand is always the best strategy for comfort.
