From the TSA website: 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 travel-sized containers that are 3.4 ounces (100 milliliters) or less per item. Placing these items in the small bag and separating from your carry-on baggage facilitates the screening process. Pack items that are in containers 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.
TSA works closely with international partners to maintain aviation security standards abroad.
The U.S. Department of Homeland Security is actively working to raise the baseline for aviation security across the globe by requiring the implementation of enhanced security measures, both seen and unseen, at approximately 280 foreign airports with direct commercial flights to the U.S., in more than 100 countries around the world. Read about the security measures and FAQ for more information on aviation security worldwide.
What to Expect
If you are flying from any of the last-point-of-departure airports into the U.S., you may experience a more extensive screening process and should prepare for additional screening of your property and personal electronic devices. We recommend arriving early to the airport to allow enough time for the screening process. Please know, there are no changes to items allowed in carry-on and checked baggage.
For your convenience, we encourage you to place powder-like substances over 12 oz. / 350 mL in your checked bags. Powders in carry-on baggage may require secondary screening, and powders that cannot be resolved by security officials will be prohibited from the cabin of the aircraft effective June 30, 2018.
