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. NOTE: This cannot be a bottle that is larger than a 3oz size with 3 oz of liquid in it. The bottle size must not be any larger than 3oz. 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 a checked luggage. Declare larger liquids. Medications, baby formula and food, breast milk, and juice for infants 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. All food items must be removed from your carry on and placed in a bin. All electronics must be full charged, if they are inspected you must be able to turn them on or step aside, plug them in and charge them enough until they can turn on.
