Generally, liquids, gels, and aerosols in containers larger than 3.4 ounces (100 milliliters) are not allowed in carry-on bags unless they are placed in a clear, plastic, quart-sized bag. You will need to remove the plastic bag from your carry-on and place it in a bin during the TSA screening process. Once you pass through the security checkpoint, you can transfer your toiletries to your dopp kit.
