You are allowed to bring liquids on a plane in carry-on luggage under the TSA's 3-1-1 rule, which means:
- Each liquid container must be 3.4 fluid ounces (100 milliliters) or less.
- All containers must fit into one clear, quart-sized (about 32 ounces) resealable plastic bag.
- Each passenger is limited to one such quart-sized bag
There is no specific limit on the number of 3.4-ounce containers you can bring, as long as they all fit in the single quart-sized bag. Typically, this allows for about seven or eight containers, totaling roughly 25 fluid ounces in volume
. Exceptions exist for medically necessary liquids (like prescription medications, baby formula, breast milk), which can exceed the 3.4-ounce limit but must be declared at security
. Liquids purchased after security (duty-free) can also exceed the limit if they remain sealed with a receipt
. In summary:
- Maximum size per container: 3.4 fl oz (100 ml)
- Maximum total volume: Whatever fits in one quart-sized bag (about 25 fl oz total)
- One quart-sized bag per passenger
- Exceptions for medications, baby items, and duty-free liquids
This ensures compliance with TSA and international liquid carry-on regulations for air travel
