Hand luggage liquids rules
Why the rule changed, where it changed, and what to do about it.
The 100 ml rule, and why it now varies
For years every airport applied the same rule: liquids in containers of 100 ml or less, all inside one clear resealable bag. Airports that have installed the newer C3 scanners can screen larger containers without taking them out of your case, so some now allow up to 2 litres. Others have gone back to 100 ml. The rule that counts is the one at the airport you are departing from, including on the way home.

What always applies
- Baby food and milk, and prescription medicines, are allowed in larger quantities at every airport, though you may be asked to prove what they are.
- Anything bought after security, including duty free, is not affected by the limit at that airport, but it can be a problem if you change flights in a country with stricter rules.
- Creams, gels, pastes, aerosols and mascara all count as liquids.
- If in doubt, pack it in the hold or buy it at your destination.
