No, you cannot bring a standard unopened bottle of Gatorade through a TSA security checkpoint in 2026, even if it is factory-sealed. Under the long-standing "3-1-1" rule, all liquids, gels, and aerosols in carry-on luggage must be in containers of 3.4 ounces (100ml) or less and fit within a single quart-sized clear bag. Since most Gatorade bottles are 12, 20, or 32 ounces, they will be flagged and confiscated at the X-ray machine. There are only two common ways to get Gatorade past security: First, you can bring a frozen bottle of Gatorade, as TSA allows solid ice (as long as there is no liquid at the bottom of the container when you reach the scanner). Second, you can bring Gatorade powder packets, which are dry and exempt from the liquid rule; you can then mix them with water from a fountain once you are inside the secure terminal. The only other exception is for passengers with documented medical conditions that require specific electrolytes, but even then, you must declare it to an officer for additional screening.
