3-1-1 for carry-ons = 3.4 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. 3.4 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. Medications, baby formula and food, and breast milk 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.
Provide advance notice to your airline or travel agent if you require assistance at the airport. TSA can only assist you with the screening process. Your airline will assist you through the airport facility and the screening queue line.
If you require a companion or assistant to accompany you through the security checkpoint to reach your gate speak with your airline representative about obtaining a gate pass for your companion before entering the security checkpoint.
The limit of one carry-on and one personal item (purse briefcase or computer case) does not apply to medical supplies, equipment, mobility aids, and/or assistive devices carried by and/or used by a person with a disability.
Pack your medications in a separate pouch/bag to facilitate the inspection process. Ensure that containers holding medications are not too densely filled, and that all medication is clearly identified. It is recommended that passengers refrain from packing any medications in their checked baggage that they do not want exposed to X-rays. Instead, send larger quantities of medications to your destination by mail or any other way preferred.
If you have medical documentation regarding your medical condition or disability, you can present this information to the Security Officer to help inform him of your situation. This documentation is not required and will not exempt you from the security screening process.
Make sure all your carry-on items; equipment, mobility aids, and devices have an identification tag attached.
TSA recommends that you bring all the necessary tools and/or appliances that you require to put on or take off your prosthetic device (e.g. wrenches, pull sleeves, etc.) should you need to remove your prosthetic device for any reason. TSA allows these tools to be carried through the security checkpoint once they have been screened (see assistive devices and mobility aids for more details on prosthetic device screening).
If you have a medical device (on the interior or exterior of your body) check with your doctor prior to traveling to determine if it is safe for you to go through the metal detector or be handwanded. If your Doctor indicates that you should not go through the metal detector or be handwanded, or if you are concerned, ask the Security Officer for a pat-down inspection instead.
Your personal supplemental Oxygen will need to undergo screening. Check with your Doctor prior to coming to the checkpoint to ensure disconnection can be done safely.
If your Doctor has indicated that you cannot be disconnected or if you are concerned, ask the Security Officer for an alternate inspection process while you remain connected to your oxygen source.
If you need an Oxygen Supplier to meet you at the gate, check with your airline well in advance of your departure about their procedures for allowing suppliers to meet you at the arrival’s gate since these procedures vary from airline to airline.
