UK Airports Set for Major Overhaul as New 3D Scanners Allow Passengers to Carry Up to Two Litres of Liquids in Hand Luggage: Everything you need to know

The UK is set to revolutionize airport security with the introduction of cutting-edge 3D scanners, enabling passengers to bring up to two litres of liquids in their hand luggage—an end to the long-standing 100ml liquid restriction. This upgrade is part of a wider initiative to improve airport efficiency by allowing liquids to stay in bags without removal at security checks, and removing the need for resealable plastic bags. The scanners, which provide clearer, 3D images of luggage contents, will be rolled out across major airports starting in 2024, with full implementation expected by 2025. Here’s everything you need to know about how these changes will impact your travel experience.

In a significant change to airport security regulations, travelers passing through certain UK airports will soon be allowed to bring up to two litres of liquids in their hand luggage. This major shift comes as part of the UK’s introduction of advanced 3D security scanners, which will replace the outdated systems currently in use. The change marks the end of the longstanding 100ml liquid limit, which has been a staple of airport regulations for over a decade.

A New Era of Airport Security

The 100ml liquid rule has been one of the most recognized travel restrictions since it was introduced in 2006, following a failed terrorist plot that aimed to bring liquid explosives aboard transatlantic flights. The attack was thwarted by British authorities, and as a result, strict regulations were imposed on carrying liquids in hand luggage. Passengers were required to comply with a 100ml limit for each liquid container, and all liquids had to be stored in a resealable, transparent plastic bag of a specific size.

Now, however, this restriction is set to be relaxed with the rollout of the UK government’s new 3D CT scanners. These innovative machines utilize advanced 3D imaging technology, replacing the old X-ray systems that only provided two-dimensional images of baggage. The upgraded scanners offer a clearer, rotatable 3D representation of the contents of luggage, making it easier to spot potential threats while allowing for more lenient rules on liquid restrictions.

The Benefits of 3D Scanners

The new 3D scanners are expected to significantly improve security screening processes at major UK airports. For travelers, the key benefit is the increased convenience. With the introduction of this technology, passengers will no longer need to remove their liquids from their bags when passing through security. The traditional requirement to take out bottles of shampoo, beverages, and other liquids will be eliminated.

With the new system, travelers will be able to carry up to two litres of liquids in their hand luggage without worrying about the 100ml limit. Additionally, this update removes the need for passengers to pack their liquids in separate resealable plastic bags, streamlining the security process.

Gradual Rollout at Select Airports

Initially, the upgraded scanners will be installed in a select number of airports, with a broader rollout expected as the government continues its efforts to modernize airport security. The Department for Transport (DfT) originally set a target for June 2024 to complete the installation of these new systems at UK airports. However, due to delays in the installation process and a need for further testing, the deadline has been extended to June 2025.

In the interim, the 100ml limit will still apply at airports that have not yet adopted the new technology. It’s important for passengers to be aware that not all airports will immediately allow for larger liquid allowances. The DfT has clarified that timelines for the implementation of the new scanners may vary by location, meaning passengers are advised to check specific airport regulations before traveling to avoid any unexpected restrictions.

What This Means for Travelers

Once the new system is fully rolled out, passengers will enjoy a more streamlined security experience. As well as larger liquid allowances, the new scanners will also enable passengers to keep laptops and other electronic devices in their bags during screening. This will help speed up the process and reduce the stress often associated with having to unpack and repack bags during security checks.

Additionally, for passengers who need to bring essential medications or dietary liquids, the existing exemptions will still apply. These include medication, baby food, and specific dietary liquids, which are not subject to the 100ml limit, provided they meet the necessary guidelines.

The introduction of the 3D scanners is expected to lead to a smoother and quicker process at security checkpoints. Passengers will no longer be required to remove their liquids or electronics from their bags, and they won’t have to scramble to fit multiple bottles of liquid into a small plastic bag. This should result in less congestion at security lines, ultimately leading to a more efficient airport experience for all travelers.

Current Liquid Restrictions

For those traveling through airports that have not yet switched to the new 3D scanners, the 100ml limit is still in effect. Passengers will need to comply with the following:

• Liquids, aerosols, gels, creams, and pastes in containers larger than 100ml will not be allowed in hand luggage.
• All liquid containers must be placed in one transparent, resealable plastic bag, which must not exceed 20cm x 20cm in size.
• The total amount of liquids in the bag should not exceed one litre.

Exemptions to the liquid rules still apply to necessary medications, infant formula or food, and dietary liquids. Travelers should always check the rules in advance to ensure compliance with the latest guidelines.

Looking Ahead

The UK’s shift towards more advanced security technology reflects a broader trend of modernization across the aviation industry. While the initial rollout may be limited to a few airports, the long-term goal is to have the majority of UK airports equipped with 3D scanners by 2025. This will help make airport security faster and more efficient, while maintaining the high standards of safety required to protect travelers.

The ability to bring up to two litres of liquids in hand luggage will be a welcome relief to many passengers who have had to adapt to the 100ml rule over the past 17 years. By improving the security experience and providing travelers with more freedom, the new 3D scanners represent a significant step forward in aviation security.

The UK is overhauling airport security with new 3D scanners, allowing passengers to carry up to two litres of liquids in hand luggage, eliminating the 100ml limit. This change, starting in 2024, will simplify security checks by removing the need for resealable bags and enhancing airport efficiency.

Conclusion

The UK’s introduction of 3D security scanners marks a pivotal moment for both passengers and the aviation industry. Not only will the change reduce the burden of liquid restrictions, but it will also lead to quicker and more efficient airport security. Travelers can look forward to a more relaxed and smoother experience, with the new rules and technology set to significantly improve the journey through UK airports. However, as the rollout continues, travelers must remain vigilant and check the rules at their specific airport to ensure compliance.
