No more 100ml bottles - all about airport security transformation

What is the current law?

When asked about the things that annoy you at the airport the answers can be endless.

Long queues, luggage limits, delays, and among them thorough security checks including liquid control.

The current 3-1-1 rule says that passengers can bring liquids in their carry-on luggage, but they must be in containers of 3.4 ounces (100 ml) or less.

These containers must fit in a clear, quart-sized plastic bag, and each passenger is allowed only one bag.

The rule was introduced by the Transportation Security Administration to improve the airport security after a failed terrorist plot involving liquid explosives in 2006 in the UK.

Are the limits going to end?

The introduction of new CT scanners might end for good the era of 100ml holiday shampoo and soap bottles.

These scanners work similarly to the ones in the hospital, showing detailed 3D pictures of what's inside your bag.

They can rotate 360 degrees and zoom in for a closer look.

Additionally, they use smart software to detect explosives, even if they're in a liquid form.

What’s even more impressive is that these scanners can tell the difference between different types of liquids.

This means they can see if you have water or something actually dangerous like hydrogen peroxide.

Why it takes so long?

Introducing new scanners poses financial and logistical challenges for the airports.

Heathrow airport with over 140 security lanes finds it hard to install new equipment without disrupting passenger flow.

Gatwick airport aims to make significant progress and complete their installation by 2025.

Some international hubs like Amsterdam's Schiphol and Frankfurt already use similar scanners.

US airports like Atlanta's Hartsfield-Jackson, Chicago O'Hare and New York’s LaGuardia are already using the new technology.

It seems like the travellers will be encountering both old and new rules during their journeys in the foreseeable future.

What does it mean for the passengers?

Removing the 100 ml liquid rule won't compromise safety as some fear.

On the contrary, it'll enhance it as the new scanners give clearer images, making it easier to spot potential threats or banned items.

Additionally, the security checks will be sped up, making travel more convenient.

Finally, lack of old rules will reduce plastic waste by cutting down on disposable bottles and bags.

Passengers will also save money by bringing their own drinks instead of buying them at pricey airport shops.
