The TSA carry-on liquids rule is different than most other carry-on rules in that it is based on a per day allowance. This means that the maximum amount of liquids that you are allowed to bring with you in your carry-on bag each day is 3.4 fluid ounces (100 mL).
The other major difference between the TSA carry-on liquids rule and most other carry-on rules is that you are not allowed to bring any type of container that can be used to store liquid drugs or aerosols. This includes, but is not limited to, sealed plastic containers, glass containers, metal cans, and even nalgene water bottles.
