FAQs
What's the liquid rule at Heathrow Terminal 5?
The standard 100ml-container rule applies. Each liquid, gel or paste must be in a container of 100ml or smaller, all fitting inside a single 1-litre clear plastic bag.
Does Heathrow Terminal 5 allow 2-litre liquids?
Not officially. Despite CT scanners being in place, the UK DfT 100ml rule is still in force. T5 staff will let small CT-scanned containers through without removing them from your bag, but anything over 100ml may still be confiscated.
Do I need to take liquids out at T5 security?
Not at the CT-scanner lanes. Staff will direct you. If you're at a traditional X-ray lane, yes — take them out and bag them.
Best time to clear T5 security?
