Airports Relax Rules: What's Changed And What It Means

Airport security rules have been relaxed in recent years, with new regulations allowing passengers to carry larger volumes of liquids and laptops through security. Since a terrorist threat in 2006, liquids have been limited to 100ml and must be presented in a clear plastic bag to prevent liquid explosives from being brought onto planes. However, advancements in technology, such as 3D security scanners, have enabled the implementation of new regulations that allow passengers to bring up to 2 litres of liquid through security. These changes aim to enhance aviation security while providing passengers with a smoother and safer travel experience.

Relaxed liquid restrictions: passengers can bring up to 2 litres of liquid through security

The UK government has announced that airport security rules on liquids will be relaxed from June 2024. This will be the biggest relaxation of aviation security regulations in decades. The new regulations will allow passengers to carry liquids in containers holding up to 2 litres through security. Currently, liquids are limited to 100ml and must be carried in a clear plastic bag. The rule was introduced in 2006 following a foiled terrorist plot to blow up planes with liquid bombs.

The change in rules will be implemented at major UK airports, including Gatwick, Heathrow, Manchester, and Birmingham. These airports will be required to install new 3D security scanners that use CT X-ray technology to provide detailed 3D images of the contents of passengers' bags. The new scanners also deploy highly advanced threat detection algorithms. This technology is already in use at Schiphol Airport in Amsterdam.

The relaxation of liquid restrictions will make travelling through UK airports easier and air travel more pleasant. It will also reduce queuing times and improve the overall passenger experience.

It is important to note that the new rules may not be in place at all airports, and passengers are advised to check the return rules for carrying liquids at their destination or transfer airports.

New 3D security scanners: CT X-ray technology provides 3D images of passengers' bags

The implementation of new 3D security scanners using CT X-ray technology is a significant upgrade from conventional 2D X-ray scanners. This new technology provides several benefits and opportunities to improve the overall airport experience for passengers.

Firstly, CT X-ray technology produces highly detailed 3D images of passengers' bags' contents, allowing screeners to differentiate between safe and prohibited items more easily. The operator can manipulate, rotate, slice, enhance and examine every detail of the item in 3D, enabling a more accurate assessment of the bag's contents. This results in fewer intrusive bag searches and faster queue times, as demonstrated at Shannon Airport in Ireland, where the introduction of CT scanners halved the time passengers spent going through security.

Secondly, CT technology eliminates the need for passengers to remove electronics, liquids, and gels from their bags, as was previously required with 2D X-ray scanners. This change improves throughput and speed, reducing the time spent at security checkpoints. It also decreases the need for physical inspections and rechecks, as the 3D images provide an unobstructed, all-dimensional view of the bag's contents.

The new CT scanners are more efficient for passengers and security personnel. While older 2D scanners required passengers to remove various items from their carry-on bags before screening, the new CT scanners only require bags to be placed in a bin for screening. This saves time for both passengers and TSA officers, who no longer need to manually inspect as many bags.

The advanced threat detection algorithms used by CT scanners further enhance security. These algorithms can automatically detect explosives and other threat items by capturing hundreds of images with an X-ray camera spinning around the items. This technology not only improves security but also creates a seamless and more efficient airport experience for passengers.

Implementation of new technology: airports can now install new technology and processes

Airport regulations have evolved significantly over the past few decades, driven by the need to address security concerns and enhance travel experiences. One notable aspect of this evolution is the implementation of new technology and processes, which has led to a relaxation of certain rules while improving safety and efficiency.

One example of this is the adoption of biometric solutions for access control. Airports have increasingly turned to biometric identifiers such as facial recognition, fingerprints, and iris scans to streamline the passenger journey and enhance security. This technology allows travellers to move through checkpoints seamlessly without presenting physical documents repeatedly. It also adds a layer of security for restricted areas, ensuring that only authorized personnel can access sensitive zones.

The use of advanced screening equipment is another instance of technological advancement in airports. Trials of new 3D security scanners, which utilize CT X-ray technology and advanced threat detection algorithms, have proven effective in enhancing baggage screening processes. These scanners provide a detailed 3D image of the contents of passengers' bags, improving the detection of potential threats.

Additionally, airports have been testing and implementing innovative solutions to address various challenges. For instance, the COVID-19 pandemic significantly impacted airport finances, and new technologies may help improve efficiency and reduce costs. Relaxing certain regulations allows airports to install and trial these new technologies, improving their operations and the overall travel experience.

The relaxation of airport regulations regarding the implementation of new technology is a positive step towards enhancing security, streamlining processes, and improving the overall airport experience for travellers. By embracing innovation and adapting to changing needs, airports can continue to provide safe and efficient services to their customers.

Liquids no longer need to be placed in a clear plastic bag

Airport security rules have been relaxed in many countries, and one of the most notable changes is that liquids, gels, and aerosols no longer need to be placed in a clear plastic bag when going through security. This change is a significant shift from previous regulations, which required passengers to follow specific guidelines for their liquids.

Previously, passengers were required to place liquids in a clear, resealable plastic bag with a maximum capacity of 1 quart or 1 litre. Each traveller was limited to one such bag, and all containers within had to hold 3.4 ounces (100 ml) or less. These restrictions were implemented to prevent liquid explosives from being carried onto planes and to facilitate the screening process.

However, with advancements in technology, such as the introduction of 3D security scanners that use CT X-ray technology, the need for separating liquids has diminished. These scanners can provide a detailed 3D image of the contents of passengers' bags and utilise advanced threat detection algorithms. As a result, passengers are now allowed to bring larger quantities of liquids through security, with the limit being raised to 2 litres in some cases.

Despite this relaxation, it is still important for passengers to be mindful of the types and quantities of liquids they bring. While water bottles and travel-sized toiletries are generally permitted, liquids such as peanut butter or yoghurt may be subject to the 3.4-ounce (100 ml) limit. Additionally, certain airports or countries may have their own specific regulations, so checking the rules beforehand is always recommended.

COVID-19 lockdowns: passenger numbers are yet to return to pre-pandemic levels

The COVID-19 pandemic and the lockdowns that ensued had a significant impact on airport operations and passenger numbers. While there have been predictions that passenger traffic could return to pre-pandemic levels, the reality is that many airports are still struggling to recover. Notably, Heathrow Airport, a major international hub, has yet to see passenger numbers rebound to pre-COVID-19 levels.

The pandemic caused a steep decline in air travel demand as countries shut their borders and imposed stringent travel restrictions. Even as restrictions eased, the aviation industry continued to grapple with the challenge of reviving passenger confidence and demand. While some regions have witnessed a faster recovery, such as Europe, which is expected to reach pre-pandemic passenger traffic levels by 2023, other regions like the Asia-Pacific market continue to lag due to ongoing COVID-19 restrictions in key aviation markets like China.

One significant factor contributing to the slow recovery of passenger numbers is the persistence of COVID-19 variants and subsequent waves of infections, which have led to fluctuating levels of travel restrictions across the globe. Moreover, the war in Ukraine and supply chain issues have also impacted the industry's rebound.

To attract travellers back to the skies, the aviation industry has been working to enhance safety measures and improve the overall travel experience. Airports have been investing in new technologies, such as advanced security scanners that utilise CT X-ray and 3D imaging technology, providing both improved security and a more seamless travel experience. These scanners are already in use at airports like Amsterdam's Schiphol, with other major airports like Gatwick, Heathrow, Manchester, and Birmingham set to follow suit.

Additionally, airports have been introducing new routes and offering cost-effective travel options to encourage more people to fly. The relaxation of certain airport security rules, such as the removal of the 100ml liquid limit, is also expected to improve the convenience and experience of air travel. Despite these efforts, however, passenger numbers at airports are still catching up to pre-pandemic levels, indicating that the road to recovery for the aviation industry remains ongoing.
