Can I bring my 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 non-alcoholic drinks on a plane, provided they are purchased after you clear the security checkpoint. Because of the 3-1-1 liquids rule, any drink brought from home must be in a container of 3.4 oz (100ml) or less. However, once you are in the "Airside" departures area, you can buy large coffees, water bottles, or sodas and bring them aboard. The most important rule in 2026 regards alcohol: while you can carry-on "mini" bottles of alcohol (under 3.4 oz), FAA regulations strictly prohibit you from consuming your own alcohol on the aircraft. All alcohol consumed on board must be served by the airline's flight attendants. This is a safety measure to allow crew to monitor passenger intoxication levels; violating this can lead to heavy fines or being banned from the airline.
