London’s Heathrow Airport has officially scrapped the long-standing 100 ml liquids limit for cabin baggage, marking a significant change in airport security procedures.

According to Financial Express, he decision follows the rollout of advanced CT security scanners across all terminals, designed to speed up screening and reduce hassle for travellers. However, while the update promises greater convenience, many flyers say the change falls short of expectations.
The new scanners generate detailed 3D images of carry-on luggage, allowing security officers to examine liquids and electronics without requiring passengers to remove them from their bags. As a result, travellers departing from Heathrow can now carry liquids in containers of up to two litres through security, and laptops and tablets can remain packed unless further checks are required.
In theory, the upgrade should make the airport experience smoother. No more decanting toiletries into tiny bottles or juggling clear plastic bags at security. For Heathrow, the move is part of a broader, multi-million-pound investment aimed at modernising one of the world’s busiest travel hubs.
Yet the response from frequent flyers has been far from enthusiastic. Many travellers have taken to social media to label the change “absolutely meaningless”, pointing out that the relaxed rules apply only when departing from Heathrow. Passengers still need to comply with the 100 ml limit at most other airports, including on return journeys or when transferring through different hubs.
Critics argue that this lack of consistency creates confusion rather than convenience. A traveller may leave London with a full-size bottle in their carry-on, only to be forced to discard it at security elsewhere. For international flyers, especially those on multi-leg journeys, the benefit can feel limited.
Despite the criticism, aviation experts say the introduction of CT scanners is a step in the right direction. Similar systems are being rolled out at airports across Europe and beyond, suggesting that broader changes to liquid restrictions may follow in time. Until then, passengers are advised to check the specific rules of every airport on their itinerary.
