3–1–1 for carry-on = 3.4 ounce bottle or less; 1 quart-sized, clear, plastic, zip-top bag; 1 bag per passenger placed in screening bin. One-quart bag per person limits the total liquid volume each traveler can bring. 3.4 oz. container size is a security measure.
Consolidate bottles into one bag and X-ray separately to speed screening.
Be prepared. Each time TSA searches a carry-on it slows down the line. Practicing 3-1-1 will ensure a faster and easier checkpoint experience.
3-1-1 is for short trips. If in doubt, put your liquids in checked luggage.
Declare larger liquids. Prescription medications, baby formula and milk (when traveling with an infant or toddler) are allowed in quantities exceeding three ounces and are not required to be in the zip-top bag. Declare these items for inspection at the checkpoint.
Come early and be patient. Heavy travel volumes and the enhanced security process may mean longer lines at security checkpoints.
