You are allowed to bring liquids in your carry-on under the TSA's 3-1-1 liquids rule, which means:

• Each liquid container must be 3.4 ounces (100 milliliters) or less.
• All containers must fit comfortably within a single quart-sized (approximately 1 liter) clear, resealable plastic bag.
• Each passenger is allowed only one such quart-sized bag of liquids, gels, aerosols, creams, and pastes in their carry-on.

There is no specific limit on the number of 3.4 oz containers you can bring, as long as they all fit in the one quart-sized bag

. Exceptions include medically necessary liquids (such as prescription medications), baby formula, and duty-free liquids purchased after security, which can exceed the 3.4 oz limit but must be declared and screened separately

. In summary, the maximum size per container is 3.4 oz, and the total volume of all liquid containers combined must fit into one quart-sized bag for carry- on luggage
