End of 100ml liquid limit at London Heathrow

Traveling through Europe’s busiest hub just became significantly easier. London Heathrow Airport has officially scrapped the long-standing 100ml liquid limit and the requirement to remove electronic devices from cabin bags, thanks to the full rollout of next-generation security scanners across all its terminals.

For the Turkish community in London, especially frequent flyers from Enfield, Barnet, and Haringey who regularly travel to Istanbul or Ercan via Heathrow, this update marks the end of a major travel headache.

Key changes for passengers

The transition to high-definition 3D CT scanners means that the old security protocols are now a thing of the past at Heathrow:

  • Liquids Up to 2 Litres: Passengers can now carry liquids in containers up to 2 litres in their hand luggage. The days of squeezing tiny bottles into small plastic bags are over.

  • Electronics Stay Inside: Laptops, tablets, and other large electronic devices no longer need to be taken out of bags for separate screening.

  • Faster Security Queues: The new technology allows for a much smoother flow, significantly reducing waiting times at security checkpoints.

A major investment in travel

Heathrow management confirmed that the multi-billion pound investment in these scanners is now active across all four terminals. The high-resolution 3D images provided by the CT technology allow security staff to inspect bag contents more thoroughly without the need for manual unpacking, maintaining high safety standards while improving efficiency.

Important advice for international travelers

While the rules have changed at Heathrow, residents in Hackney and Islington should keep the following in mind:

  1. Check Return Rules: Not all airports worldwide have upgraded to this technology. If you are flying back to London from an airport that still uses older scanners (including some regional airports in Turkey), you will still need to follow the 100ml rule for your return journey.

  2. Transfer Restrictions: If you have a connecting flight at another hub, ensure that their security rules align with your carry-on contents to avoid items being confiscated during transfers.

This modern shift is expected to be welcomed by business travelers and families alike across Camden and Southwark, making the journey from London to the rest of the world a far more seamless experience.
