Your liquids bag

The 3-1-1 / 100 ml rule: all liquids, gels, creams and aerosols in carry-on must be in containers 100 ml or less, all fitting in ONE transparent re-sealable bag of up to 1 L, one bag per passenger. Newer CT scanners at some major airports (Schiphol, Heathrow T2/T5, JFK T7, Tokyo Narita) ease this — but the destination airport still applies on the return trip.

The 100 ml rule applies to the container, not the contents

A common misunderstanding: the 100 ml limit applies to each container's labelled capacity, not how much liquid is actually inside. So a 200 ml bottle that's half full still fails the check, even though it only holds 100 ml of liquid. The rule originated as a counter-terrorism measure after the 2006 transatlantic plot and is enforced at every major airport — the US calls it 3-1-1 (3.4 oz containers, one quart bag, one bag per passenger), the EU and UK call it 100 ml + 1 litre bag. New CT scanners at some airports (Heathrow, Schiphol, Frankfurt) are starting to lift this, but the rollout is uneven — verify with your departure airport before packing larger bottles.

⚠️ Container size is what matters, not how much liquid is inside. A 200 ml bottle half-empty is still 200 ml — it gets confiscated. Decant into ≤ 100 ml travel bottles before flying.
