100ml liquid airport security rule due to end in 2024

The 100ml airport liquid rule, which has been in place for over a decade, is set to end. This rule, which was implemented in response to security concerns following the 9/11 terrorist attacks, has long been a source of frustration for travellers, who have had to carefully measure and limit the amount of liquids, gels, and aerosols they carry in their carry-on bags.

The rule change, which was announced by the International Air Transport Association (IATA), will take effect in the coming months and will allow travellers to carry an unlimited amount of liquids, gels, and aerosols in their carry-on bags, as long as they pass security screening. This means that travellers will no longer have to decant their liquids into small bottles, or risk having them confiscated at security checkpoints.

The decision to end the 100ml rule has been met with a mixed response. Some travellers are thrilled at the prospect of being able to carry more liquids, gels, and aerosols on their flights, while others are concerned about the potential security risks.

One of the main reasons for ending the 100ml rule is the increased use of advanced security technologies at airports. These technologies, such as computed tomography (CT) scanners, can accurately detect and identify liquids, gels, and aerosols, making it possible to screen large volumes of these items quickly and efficiently.

The use of CT scanners has already been introduced at several major airports around the world, and their use is expected to become more widespread in the coming years. This means that airport security staff will be able to screen larger volumes of liquids, gels, and aerosols, without significantly increasing the time it takes to get through security checkpoints.

Another reason for ending the 100ml rule is the changing nature of the threat to aviation security. In the years since the 9/11 attacks, the focus of terrorist groups has shifted away from targeting aircraft and towards other types of attacks, such as bombings and mass shootings. As a result, the threat posed by liquids, gels, and aerosols has diminished, making it less necessary to impose restrictions on their transport.

Despite the increased use of advanced security technologies and the changing nature of the threat to aviation security, some experts are still concerned about the potential security risks of ending the 100ml rule. They argue that terrorists could still attempt to use liquids, gels, and aerosols as part of a broader attack, and that the increased volume of these items allowed on flights could make it easier for them to do so.

To address these concerns, IATA has stated that security measures at airports will be enhanced in other ways to compensate for the ending of the 100ml rule. This could include increased use of trained sniffer dogs, more thorough passenger screening, and enhanced intelligence gathering and analysis.

Despite these measures, it is likely that some travellers will still be wary of the potential security risks associated with the ending of the 100ml rule. It will be important for airports and airlines to reassure passengers that they are taking all necessary steps to ensure the safety of flights, and to address any concerns or fears that passengers may have.

Overall, the ending of the 100ml airport liquid rule – which won’t actually be until 2024 – is a significant change that will have a major impact on the way that travellers pack and carry liquids, gels, and aerosols on flights. While it may take some time for passengers to adjust to the new rules, the increased convenience and flexibility will likely be welcomed by many. As long as security measures are enhanced in other ways to compensate for the change, the ending of the 100ml rule should not pose any significant risks to aviation security.
