Since January, passengers flying from some UK airports have been allowed to carry up to two litres of liquids in their hand luggage, replacing the long-standing 100ml rule, thanks to new CT scanners. In a statement, Heathrow Airport said: “Passengers travelling through all terminals no longer need to remove liquids or electronics from their hand luggage, or juggle plastic bags at security. The UK’s hub has become the largest airport in the world to fully roll out next-generation CT (computed tomography) scanners – promising faster queues, less stress and a smoother start to journeys.”

UK airports that have ditched the 100ml rule

• Belfast International
• Belfast City
• Birmingham
• Bristol
• Edinburgh
• London Gatwick
• London Heathrow

However, the change has not been rolled out everywhere, with many airports still enforcing the 100ml limit and requiring liquids to be removed and placed in clear plastic bags.

Exemptions remain in place for essential medicines, baby food, and milk, as well as special dietary requirements. Travellers are being urged to check their airport’s rules before flying – especially ahead of the busy Easter period – to avoid delays or having items confiscated at security.

Reacting to the change, one traveller flying from Gatwick Airport wrote on Reddit: “Makes the journey just that little bit less stressful. Leave everything in your bag – laptop too.”

Another added: “Edinburgh is the same, which is really handy.” A third explained: “It’s because of a new generation of scanners that allow more liquids and mean you don’t have to remove laptops – but only a few airports have them so far.”

However, not everyone is convinced. One user said: “This change is useless until all major airports follow suit. It’s fine on the way out, but if your return airport still has the old rules, you end up throwing things away. It also causes confusion, especially when different London airports have different rules. It should be all or nothing.”

Another added: “I’ve been travelling with just carry-on for years now and wouldn’t go back. There’s something freeing about not carrying full-size toiletries when you only need a small amount.”
