11 Full-Sized Liquids TSA Allows Through Airport Security

Travelers weary of the Transportation Security Administration’s (TSA) restrictions on the size of liquids allowed on aircraft may soon find relief. The current 3-1-1 rule, which mandates that all carry-on liquids be stored in 3.4-ounce containers inside a quart-sized plastic bag, could be phased out thanks to new technology. Computed tomography scanners, which use 3D imaging to detect unauthorized liquids at security checkpoints, could render travel-sized toiletries obsolete at some airports.

The United Kingdom had initially planned to implement this new security technology and lift liquid limitations as early as June 1 of this year. However, the start date has been postponed. A representative for the TSA in the United States has stated that the agency anticipates the liquid limit will be lifted in the coming years, but for now, the restrictions remain in place.

The TSA’s press secretary, Robert Carter Langston, has previously stated that while more CT scanners are being deployed at checkpoints, the agency is still years away from announcing a change to the current liquids rule. Despite this, there are currently 11 exceptions to the 3-1-1 rule.

Prescription medications, whether liquid, gel, or aerosol, are allowed through TSA, as are over-the-counter liquid medications or contact lens solution in reasonable quantities. Other exceptions include freezer or ice packs necessary to keep medications cold, medical accessories like IV bags or syringes, fresh eggs, fish transported in water, and wet batteries. Breast milk and formula for infants, liquid-filled items for teething, and food or drinks for babies and toddlers are also permitted. Larger duty-free items purchased at the airport can also pass through the security checkpoint if they are sealed in tamper-evident bags.

TSA officers may test liquids, gels, or aerosols for explosives or concealed prohibited items. Passengers are advised to inform security agents about larger liquids. If these items cannot be screened by machine or travelers prefer not to have their liquid medication opened or exposed to X-ray, alternative examination methods can be used. Additional steps will be taken to clear the liquid, and the passenger or the traveling guardian will undergo additional screening procedures, which may include AIT screening, a pat-down, and additional screening of carry-on property.
