Can you carry-on 3 oz of alcohol?

For carry-on, same rules apply as above. You are limited to containers of 3.4oz or less that fit in your quart-sized bag. For checked bags you are limited to five liters per passenger. However, it must be in unopened retail packaging!



Yes, you can carry on 3 oz of alcohol, provided it fits within the TSA "3-1-1" rule for liquids. This rule mandates that all liquids, gels, and aerosols must be in containers of 3.4 ounces (100ml) or less, and all containers must fit inside a single quart-sized, clear, plastic, zip-top bag. However, there is a major catch: FAA regulations strictly prohibit passengers from consuming their own alcohol on board an aircraft. You can bring the 3 oz bottle through security, but you cannot open or drink it during the flight unless it is served to you by a flight attendant. Furthermore, if the alcohol is over 140 proof (70% ABV), it is completely prohibited in both carry-on and checked luggage due to its high flammability. Always ensure the original retail packaging is intact to avoid issues at the security checkpoint or during boarding.

As much of a tease as it may be, passengers are permitted to bring nips and shooters under the legal 3.2- ounce limit on board — they just can't be opened until after deplaning. Ridiculous? Maybe, but unless you want to risk facing a hefty fine, it's best to keep your booze stowed away.
