3-1-1 Liquids Rule

You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes in your carry-on bag and through the checkpoint. These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item. Placing these items in the small bag and separating from your carry-on baggage facilitates the screening process. Pack items that are in containers larger than 3.4 ounces or 100 milliliters in checked baggage.

Any liquid, aerosol, gel, cream or paste that alarms during screening will require additional screening.

Disabilities & Medical Conditions / Passenger Support

To ensure your security, all travelers are required to undergo screening at the checkpoint. You or your traveling companion may consult the TSA officer about the best way to relieve any concerns during the screening process. You may provide the officer with the TSA notification card or other medical documentation to describe your condition.

Travelers requiring special accommodations or concerned about the security screening process at the airport may also ask a TSA officer or supervisor for a passenger support specialist who can provide on-the-spot assistance.

If you have other questions or concerns about traveling with a disability please contact TSA Cares 72 hours prior to traveling at (855) 787-2227. TSA Cares provides travelers with disabilities, medical conditions and other special circumstances additional assistance during the security screening process, and can answer questions about screening policies, procedures and what to expect at the security checkpoint.

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.

Wine is a liquid! Travelers cannot take wine on board in carry-on baggage.

Come early and be patient. Heavy travel volumes and the enhanced security process may mean longer lines at security checkpoints.

Remember Passengers are asked not to lock their luggage for faster screening. Cable or zip ties or other easily cut or opened ties are recommended for securing luggage.

Security screens every passenger’s baggage before it is placed on an airplane. While technology allows security officers to electronically screen bags, there are times when they need to physically inspect a piece of luggage. TSA has worked with several companies to develop locks that can be opened by security officers using universal “master” keys so that the locks may not have to be cut. These locks are available at airports and travel stores nationwide. The packaging on the locks indicates whether they can be opened by security officers. Visit TSA’s website for more information about security locks.

TSA works with airlines and airports to anticipate peak traffic and be ready for the traveling public.

Security screening at the Charles M. Schulz – Sonoma County Airport is handled by the Trinity Technology Group. TSA contracts with and monitors Trinity’s operations. Trinity follows regulations and procedures required by TSA.

Passengers with questions regarding screened bags can call (888) 431-2685 or visit where they can file claims or complaints for their lost items.
