What You Need to Know

Each time you enter into an airport, a number of precautions are taken to ensure your flight is safe. By following the procedures below and ensuring that your baggage meets Transportation Security Administration (TSA) standards, the airport screening process can  be much faster and easier.

Start Here

TSA and our security partners conducted extensive explosives testing since August 10, 2006 and determined that liquids, aerosols and gels, in limited quantities, are safe to bring aboard an aircraft. The one bag limit per traveler limits the total amount each traveler can bring. Consolidating the bottles into one bag and X-raying them separately from the carry-on bag enables security officers to quickly clear the items.

  • 3-1-1 for carry-ons = 3.4 ounce (100ml) 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 ounce (100ml) container size is a security measure.
  • 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. Officers may need to open these items to conduct additional screening.

Tips

  • Duty Free Travel Information - To avoid the risk of having to abandon your liquid duty free items in the U.S. and abroad know the rules at home and abroad.
  • Prohibited Items - Sharp items, sporting goods, guns and firearms, tools, martial arts and self defense items, explosive and flammable materials, chemicals, and other dangerous items are strictly prohibited. Check the online database if you have questions.
  • Traveling with children - You are encouraged to travel with only as much formula, breast milk, or juice in your carry-on needed to reach your destination.
  • Travelers with Disabilities and Medical Conditions - All disability-related equipment, aids, and devices continue to be allowed through security checkpoints once cleared through screening.
