Can you bring your own drinks on a plane?

Water and other non-alcoholic drinks That means that the maximum amount of each liquid you bring on board has to be 3.4 ounces or 100 milliliters and all your liquids/gels must fit in one quart size bag. Having said that, it might be a better idea to buy a drink after you pass the security checkpoint.



You can bring your own drinks on a plane, but you must follow the TSA "3-1-1" liquids rule for security and the airline's rules for consumption. You cannot bring liquids larger than 3.4oz (100ml) through the security checkpoint; however, you can bring an empty reusable water bottle and fill it at a "Hydration Station" once you are inside the "sterile" terminal area. You can also purchase full-sized drinks (sodas, juices, water) at airport shops and bring those on board. For alcoholic beverages, the rules are much stricter: while you can bring "mini-bottles" of alcohol through security (if they fit in your quart-sized bag), you are legally prohibited from drinking your own alcohol on the aircraft. FAA and international regulations require that all alcohol consumed on board must be served by the airline's flight attendants. This ensures that the crew can monitor passenger intoxication levels for safety. In 2026, many airlines have increased enforcement of this rule, with fines for "self-serving" alcohol reaching up to $11,000 for non-compliant passengers.
