Understanding TSA Liquid Restrictions for Carry-On Luggage

When traveling by air, it’s essential to adhere to the regulations set by the Transportation Security Administration (TSA) regarding liquids. One of the key restrictions involves the size of liquid containers allowed in carry-on luggage.

Maximum Container Size for Liquids

According to TSA regulations, all liquids carried in carry-on luggage must be in individual containers that hold no more than 3.4 ounces (or 100 milliliters). This applies to all liquids, including gels, pastes, and aerosols.

Number of Containers Allowed

The TSA does not specify a limit on the number of 100ml containers you can carry on. However, keep in mind that all liquids must be placed in a clear quart-sized bag, and the total volume of liquids cannot exceed one quart (946ml).

Other Liquid-Related Regulations

• Liquids purchased after security: You can purchase duty-free liquids at airport stores after passing through security. However, these liquids must be kept in a tamper-proof bag until you reach your final destination.
• Medications and baby formula: You can carry larger quantities of medically necessary liquids and baby formula, but you may need to provide documentation or a prescription.
• Checked luggage: Liquids over 3.4 ounces can be packed in checked luggage. There are no size or quantity restrictions for liquids in checked luggage.

Consequences of Violating TSA Liquid Restrictions

Violating TSA liquid restrictions may result in fines, confiscation of prohibited items, and potential delays in your travel.

By following these guidelines, you can ensure a smooth and secure travel experience.
