All liquids, aerosols and gels that you intend to take in your carry-on baggage must be in containers 100ml in volume or smaller. (This is about equal to 100gm in weight).

For the purposes of airport security in 2026, a 100g tube is generally treated as the same as 100ml. Aviation security rules (the "3-1-1" rule) classify both liquids and "liquefiable" solids—such as gels, pastes, and creams—under the same 100ml / 100g (3.4 oz) limit per container. If your toothpaste or moisturizer is labeled "100g," it will pass the high-intensity screening as long as it fits within your single, quart-sized clear plastic bag. However, any container labeled with a weight or volume exceeding 100ml / 100g will be confiscated, even if it is only partially full. For 2026 travelers, a "pro-tip" is to remember that some UK and European airports have replaced this rule with a premier 2-liter limit thanks to new CT scanners; however, until this is global, the 100g/100ml standard remains the high-quality "gold standard" for a frictionless security experience. Always check your return airport's specific rules to ensure your high-value toiletries aren't seized on your way home.
