Quick answer
The 100 ml rule still applies almost everywhere. The US allows containers up to 3.4 oz (100 ml) in one quart-size bag, and Canada allows 100 ml containers in one 1 L bag. The UK is mixed: most airports keep 100 ml, but some (including Heathrow T2–T5 and Gatwick) allow up to 2 litres. The EU reinstated 100 ml at airports with new scanners in 2024, though some airports such as Dublin now allow 2 L. Pack for 100 ml unless your airport confirms otherwise.
Rules apply at each airport you pass through
A larger allowance at your departure airport doesn’t carry over. On the way home, or at a connecting airport, the 100 ml limit may apply again.

United Kingdom: airport by airport
GOV.UK says most UK airports still apply the 100 ml limit, but some with new scanners allow containers up to 2 litres. Examples from official airport information:
- Heathrow: 2 L allowed at Terminals 2, 3, 4 and 5.
- Gatwick: 2 L allowed.
- Manchester: 100 ml limit, but liquids don’t need to go in a bag.
European Union
In 2024 the European Commission reinstated the 100 ml limit at airports using new C3 scanners, from September 1, 2024. We found no official EU act lifting that restriction, but individual airports have changed their rules: Dublin Airport, for example, allows 2 L. Check your airport’s website.
Exemptions
Medicines, baby food and special dietary items are usually allowed in larger amounts, but you may have to declare and show them at screening. Check the official page for your departure country above.
Packing tips
- Use solid toiletries (shampoo bars, solid sunscreen) to free up space.
- Decant into labelled 100 ml bottles.
- Keep your liquids bag at the top of your carry-on.
- Duty-free liquids bought at the airport usually come in sealed bags. Keep the receipt.
