what amount of liquid can you take on a plane

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 them from your carry-on baggage facilitates the screening process. Liquids, gels, and aerosols that are over 3.4 ounces or 100 ml should be packed in checked baggage, even if they are in a secure, tamper-evident bag. However, there are exceptions for certain items such as baby and toddler drinks and food, breast milk, and infant formula, which can be carried in quantities needed during the flight or at the destination if they are unavailable at the destination and cannot be purchased after the security checkpoint. Additionally, completely frozen liquids are not considered to be liquid and are not subject to the 3-1-1 rule. Its important to note that the TSA allows hand sanitizers of up to 12 ounces due to the COVID-19 pandemic.
