Airport liquid rules: What you need to know about the return of the 100ml limit

Just when you thought packing for your holiday couldn't get any more complicated, there's a new twist in the airport security saga. As of 1 September 2024, travellers flying to and from Europe are facing an unexpected return to stricter liquid limits in hand luggage.

Yes, you read that right – the 100ml rule is back, even at airports that had already announced its demise.

The sudden U-turn comes after both the European Union and the UK reintroduced the 100ml liquid limit at all airports, including those with fancy new 3D scanners.

The reason? Concerns about the effectiveness of these new scanners in detecting potential threats. For holidaymakers, this means a return to the familiar dance of decanting shampoo into tiny bottles and juggling clear plastic bags at security checkpoints.

While authorities in the UK and EU insist this is a ‘temporary measure,’ no end date has been given.

To help you navigate these changes and avoid any costly last-minute goodbyes to your favourite perfume, we've put together this comprehensive Q&A guide.

What are the current rules for liquids in hand luggage?

As of 1 September 2024, the following rules apply at EU airports:

• Liquids, aerosols, gels, pastes, lotions and cosmetics must be in containers of 100ml or less.
• These containers must be carried in a resealable clear plastic bag.
• The plastic bag should have a maximum volume of one litre and you're limited to one bag per person.

Didn't some airports relax these rules recently?

Yes, some airports had started using new 3D scanners that allowed passengers to carry larger amounts of liquids. However, both the EU and UK have recently reintroduced the 100ml limit, even at airports with the new scanners.

Why have the rules changed back?

The European Commission and UK authorities received information suggesting that the new scanning equipment might not meet the required security standards. The reintroduction of the 100ml rule is described as a ‘temporary measure’ to allow for further improvements to the new checkpoint systems.

Does this affect all UK airports?

A U-turn by authorities in the UK means that the 100ml rule once again applies to all UK airports. The change will even affect passengers travelling via six regional UK airports that already had fully implemented the new scanners, including Aberdeen, Leeds Bradford, London City, Newcastle, London Southend and Teesside.

What about airports outside the EU and UK?

The 100ml limit is widely adopted globally. However, you may find that some airports outside of Europe, such as Boston Logan International Airport in the US, which recently installed new 3D scanners, no longer require passengers to abide by a liquid limit.

Rules can vary by country, so it's always best to check with your specific airport or airline before travelling.

Do I need to remove liquids from my bag at security?

In most cases, yes. You'll need to remove your clear plastic bag of liquids and place it in a tray for separate scanning. Some airports with new technology may allow you to keep liquids in your bag, but it's best to be prepared to remove them.

What counts as a ‘liquid’ under these rules?

The term ‘liquid’ includes:

• Water and other drinks
• Soups and syrups
• Creams, lotions and oils
• Perfumes
• Sprays and aerosols
• Gels (including hair and shower gels)
• Pastes (including toothpaste)
• Make-up in liquid form (like mascara)
• Any other items of similar consistency

Are there any exceptions to the 100ml rule?

Yes, there are a few exceptions, including medicines and special dietary products (like baby food) needed during the trip, as well as duty free items purchased after security checks.

How long will these restrictions last?

Unfortunately, there's no clear timeline. Both EU and UK authorities have described the reintroduction of the 100ml limit as "temporary," but haven't specified an end date.

What should I do to avoid delays at security?

To make your journey smoother:

• Pack liquids in containers of 100ml or less.
• Place these containers in a clear, resealable plastic bag.
• Keep this bag easily accessible in your hand luggage.
• Be prepared to remove the bag and place it in a tray at security.
• Check your airport's specific rules before travelling, as some may have slightly different procedures.
