• 3: Passengers are permitted to carry liquids in containers that hold a maximum of 3.4 ounces (100 milliliters) each.
• 1: All liquids, aerosols, gels, creams, and pastes must fit into one quart-sized, transparent plastic bag.
• 1: Only one quart-sized bag is allowed per passenger.

Acceptable Liquids:

Liquids that are acceptable for carry-on include:

• Water and other beverages
• Shampoo and conditioner
• Toothpaste
• Sunscreen
• Hairspray

Prohibited Liquids:

Liquids that are prohibited in carry-on bags include:

Exemptions:

There are certain exemptions to the 3-1-1 rule:

• Medications (prescription and over-the-counter) in larger containers
• Baby formula or breast milk (reasonable quantities)
• Items purchased in the secure area of the airport

Consequences of Non-Compliance:

If liquids exceed the specified size limits or are not properly packed in the quart-sized bag, they will be confiscated during security screening. Passengers may also face delays or penalties.

Tips for Adhering to the Rule:
