The Transportation Security Administration (TSA) operates the nation's airport security checkpoints. By familiarizing yourself with TSA's policies and procedures, you will clear security with maximum ease and minimum inconvenience.
What you need to know before you go
The 3-1-1- Rule
Passengers are allowed to pack liquids, gels, and aerosols in carry-on bags ONLY when they are in 3 oz. or smaller containers in a 1-quart, clear plastic zip-top bag. One bag per passenger is allowed. Plastic bags must be removed from carry-ons and placed in screening bins for visual inspection and separate screening.
Permitted and prohibited items
Curious about what you can take on board an aircraft in your carry-on bag or checked luggage? Unsure if a particular item is allowed on a plane at all? Those who want or need to travel with medication and medical devices, electronics, sharp objects, sporting goods, guns, tools, self-defense items, explosive and flammable materials, food and drinks, and other items should review this list.
Travelers with disabilities and medical conditions
If you are a traveler with a physical disability (or a caregiver for a disabled passenger), please review the latest TSA information about traveling with medical conditions, medical equipment, and more.
Traveling with children
Do you have questions about traveling with infants, toddlers, or small children? For security rules regarding traveling with infant formula, breast milk, strollers, car seats, and more, please review this information.
Traveling outside the United States
If you are traveling to Mexico, Canada, or any other country, please review the requirements for international travel, including passports and documents required to proof citizenship and identity. Only certain documents are accepted when attempting to reenter the United States. Allow six to eight weeks in advance of your travel date to obtain, replace, or change a passport. U.S. Customs & Border Protection is a good source of information about crossing the U.S. border by air, land, and sea.
Traveling with special items | Traveling with food or gifts
If you'll be transporting large, unusual, or potentially dangerous items, be sure to review these TSA guidelines, which include everything from traveling with wine, camping gear, and crematory containers and remains of the deceased to precious metals and coins, knitting needles, paintball equipment, parachutes, and more. Always check with your airline about their policies and fees for transporting large or oversize items.
