Liquids and laptop can stay in your hand luggage, says Heathrow
New 3D security scanners may ease passenger stress and cut queue times

Airport security queues could soon be less stressful for Heathrow passengers who should be able to keep liquids and laptops in their hand baggage when new 3D scanners are introduced.

Following successful trials of the new equipment, the UK’s biggest airport plans to spend £50m on new scanners across its four terminals by 2022.

The computed tomography (CT) scanners, used in hospitals to scan patients, produce more detailed images that allow security staff to assess cabin bags with electronic equipment and liquids inside.

The technology is expected to lead to a relaxation of current rules, which state that passengers can only carry liquids such as toiletries or medicine in individual containers of 100ml or less, with the items placed in a separate, clear plastic bag to pass through security. The changes should cut queuing times, as well as reduce plastic waste.

There are hopes that the improved technology could potentially end the liquids ban altogether. However, abolition would likely require the scanners to be installed at all airports, an expensive process that could take several years beyond Heathrow’s 2022 target.
