Can you take over 100ml on international flights?

There are restrictions on liquids that can be brought on board the aircraft(for international flights). For international flights, all liquids stored in containers with a capacity exceeding 100 ml(g) are prohibited from being brought onto the aircraft.



Historically, the answer was a strict "no" for carry-on bags, but in 2026, the rules are changing at select airports equipped with advanced CT (Computed Tomography) scanners. At major hubs like London Heathrow, Gatwick, and several others in the UK and Europe, the 100ml limit is being scrapped, allowing passengers to carry up to 2 liters of liquids. However, this is not yet universal. If your departure or arrival airport still uses traditional X-ray machines, you must strictly adhere to the 100ml (3.4 oz) limit per container, all packed in a single quart-sized clear bag. For 2026 travelers, the "golden rule" is to check the specific liquid policies of every airport in your itinerary; unless you are certain every stop has the new scanners, sticking to the 100ml rule is the only way to guarantee your toiletries won't be confiscated.
