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 3.4 ounces (100 milliliters) or less per item. Placing these items in the small bag separate from your carry-on baggage facilitates the screening process. Pack items 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.


Inbound International Flights

You may carry liquids more than 3.4 oz or 100 ml in your carry-on bag if:

  • You are traveling internationally to the United States with a connecting flight.
  • They are in transparent containers.
  • You bought them at a duty-free shop where it is packed in a secure, tamper-evident bag.

Liquids more than 3.4 oz or 100 ml not in a secure, tamper-evident bag must be packed in checked baggage.
