Place each liquid or gel toiletry in a container that is 3.4 oz. or smaller. If the liquid or gel is already packaged in a container of 3.4 oz. or smaller, that is acceptable. Aerosols must be pre-packaged in containers 3.4 oz. or less. You may not use larger bottles and fill them partially or pack rolled-up toothpaste tubes.
Place all of the small containers into a quart-size, zip-style, clear plastic bag and seal. You may only have one bag. Gallon-size bags or bags that don't zip closed are not allowed.
Remove the bag from your carry-on at the airport, and place it on the conveyor belt to complete the X-ray screening.
