Are there still liquid restrictions on international flights?

Each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or100 milliliters.



Yes, in 2026, liquid restrictions still exist, but they are becoming increasingly inconsistent due to the rollout of advanced CT (Computed Tomography) scanners. At major global hubs like London Heathrow and many airports across the European Union, the traditional "100ml / 3.4oz" rule is being phased out, allowing passengers to carry up to 2 liters of liquid in their hand luggage. However, in the United States and many other parts of the world, the TSA's 3-1-1 rule remains the standard for most travelers. This means liquids, gels, and aerosols must be in 100ml containers or smaller, all fitting into a single quart-sized clear bag. The 2026 travel landscape is currently in a "transition phase," where the rules depend entirely on the technology present at a specific airport's security lane. Travelers are advised to stick to the 100ml rule unless they are certain their departure and any transit airports have the new scanners, as items cleared at one airport may still be confiscated during a connection at another that still uses older technology.
