Is the 100ml Liquid Rule for Cabin Luggage Changing in 2024?

Get ready to bid farewell to the era of squeezing your toiletries into tiny bottles! The 100ml liquid rule for cabin luggage is undergoing a revolutionary change set to take effect in 2024.

Why? Well, it’s all thanks to the introduction of special 3D scanners across the UK’s airports. Here’s everything you need to know about the new 100ml liquid rule for cabin luggage.

Liquid Rule for Cabin Luggage

What Are the Current Restrictions on Liquids?

Currently, most airports worldwide enforce a limit on the amount of liquid you can carry in your cabin luggage. Typically, UK guidelines give a limit of 100ml of liquid per container – and the amount of containers you can bring depends on how many you can cram into a 20cm x 20cm airport-issue clear plastic bag.

Why Are These Restrictions in Place?

The liquid restrictions date back to 2006, when the Met Police foiled a terrorist plot involving liquid explosives concealed in 500ml soft drinks bottles. The UK and US swiftly banned all liquids from hand luggage, except for baby food and milk.

The restrictions eased a little in late 2006, with smaller amounts of liquids in 100ml containers placed within clear sealable bags allowed in hand luggage, that had to be removed from luggage during security checks.

Here's the baggage allowance and luggage limits for flight bookings with Ryanair, easyJet, Wizz Air, British Airways, Jet2 and TUI in 2023.

How Does The New Scanner Work?

By using new CT X-ray technology, airport security will be able to create 3D images of the contents of passengers’ bags to detect any security threats. Like before, bags are placed on a conveyor belt and passed through scanning machines – but this time with your liquids and laptop kept in the bag.

This new technology means manual hand luggage checks at airport security won’t be needed any more, so you won’t have to remove liquids or electrical devices like laptops from your hand luggage, making for a quicker and smoother journey through the airport.

What Will the New Liquid Allowance Rule Be?

As part of the introduction of this new 3D technology, the 100ml liquid rule will be scrapped. Instead, the limit will be extended to two litres per passenger for cabin luggage.

Once the 100ml liquid rule is gone, you’ll be able to bring liquids in a container of any capacity – you won’t have to distribute liquids in 100ml containers like before. However, some banned substances will remain banned regardless of their capacity; this includes things like flammable solids and liquids, alcohol over 70% volume and aerosol paint cans.

UK travellers visiting Europe will need an ETIAS visa-waiver in the near future. Here's when it will come in and how to apply when it does.

When Might the 100ml Liquid Rule Change?

The UK government has set a deadline of June 2024 for UK airports to introduce the new 3D scanning technology.

However, Heathrow, Gatwick, Stansted and Manchester airports have stated that they are behind schedule and so whilst they may have some scanners installed by June, they don’t expect them all to be ready to go until 2025.

Therefore, whilst you may come across a new scanner when flying out the UK this year, you can’t bank on being able to use one at these airports. Sob!

When Will UK Airports Introduce 3D Scanners?

While the UK government has set a clear deadline, the actual timeline for the full implementation of 3D scanners across all UK airports varies.

Currently London City Airport and Teeside International Airport are the only UK airports fully operating the new technology. Several major UK airports are still in the trial phase, including Gatwick, Heathrow, Stansted and Luton, so if you’re flying from these airports you might just find you’re saved the bother of removing your liquids (and electronics) at security – but it’s not a given.

What Airports Have Already Introduced 3D Scanners?

Ireland has already lifted the ban and introduced the 3D scanners in some of their airports like Shannon and Donegal. In the UK, Teesside Airport was the first airport to introduce the changes fully, followed by London City Airport.

On a global scale, similar technology is also being used in Amsterdam’s Schiphol Airport and US airports like Hartsfield-Jackson in Atlanta, Georgia, and O’Hare in Chicago.

Bear in mind that while a few airports have made the changes, most of the world’s airports are lagging behind when it comes to the new 3D scanners. So, although you may not have to bother whipping out your liquids on one end of your journey, you might well have to do it on the other.
