Make Your Trip Better Using 3-1-1

• 3-1-1 for carry-ons = 3 ounce bottle or less (by volume) ; 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 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. Medications, baby formula and food, breast milk, and juice are allowed in reasonable 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.
