TSA Prepares to Lift Liquid Restrictions in U.S. Airports

Air travelers in the United States are set to experience notable changes to the restrictions on liquids in carry-on baggage, as the Transportation Security Administration (TSA) prepares to lift the longstanding 3-1-1 rule. This shift comes amid advancements in security technology, primarily new Computed Tomography (CT) scanners, which can accurately detect hazardous items without the need for stringent liquid size limitations.

The current 3-1-1 rule, established after the September 11 attacks, limits liquids to containers of 3.4 ounces (100 milliliters) each, which must fit in a single quart-sized, clear resealable plastic bag. However, this rule may soon be repealed, allowing passengers to carry full-sized liquid items, including medical liquids, baby formula, and other necessities, through airport security without restriction.

Several media sources have reported that TSA will allow up to twelve types of liquids in larger quantities, including:

  • Breast milk and infant formula
  • Baby food and necessary beverages for infants
  • Liquid medications, including full-size containers
  • Hand sanitizers and aerosol deodorants
  • Eye drops and nasal sprays
  • Live fish and other aquatic specimens in water

These anticipated changes aim to improve the travel experience and reduce the waste associated with discarding excess liquids. Other countries, particularly in Europe, have begun introducing similar relaxation of liquid restrictions but face delays in the rollout of new scanning technologies.

While the TSA is making strides toward relaxation of the rules, various U.S. airports may take time to adjust. Some airports have already begun the installation of advanced scanners, but a comprehensive overhaul of liquid restrictions on a nationwide level is expected to take several years, given the scale and logistics involved across hundreds of screening lanes.

In the broader context, European airports have also seen temporary setbacks as they reinstate the 100ml liquid limit until technical issues with new scanners can be resolved. Ultimately, travelers in the U.S. can anticipate a more convenient air travel experience in the near future alongside the integration of enhanced security technology.
