Europe's airport liquid rules are changing: what travelers need to know

The familiar airport routine of squeezing toiletries into tiny bottles may finally be starting to change in parts of Europe. New CT security scanners can allow passengers to carry larger liquid containers through selected checkpoints, in some cases up to two litres. That does not mean the 100ml rule has disappeared. The important point for travelers is that the change is uneven. Some airports and terminals are moving to the newer system, while many others still apply the traditional restrictions.

Why the rules are changing

The shift comes from the rollout of more advanced cabin baggage scanners, often described as C3 or CT scanners. These machines create detailed three-dimensional images of hand luggage, giving security staff a clearer view of what is inside a bag.

Where the technology has been installed, tested and approved, the security process can become less awkward. Liquids may be allowed in larger containers, and laptops or tablets may not always need to be removed from cabin bags.

For passengers, that can mean fewer trays, less repacking and less stress at the checkpoint. For airports, it can make screening more efficient once the systems are fully operating.

The 100ml rule is not gone everywhere

The main risk is assuming the relaxed rule applies across Europe. It does not.

At many airports, liquids are still restricted to containers of no more than 100ml, usually carried in a transparent one-litre bag. That remains the safest default when you are not sure what your departure airport allows.

Even within countries, implementation can vary. One airport may have the newer scanners in use, another may be waiting for approval, and a large airport may have different rules depending on the terminal or checkpoint.

That makes this less of a Europe-wide rule change and more of a gradual airport-by-airport rollout.

Airports reported to allow larger liquids

According to the notes from The Portugal News, airports reported to allow liquid containers of up to two litres include:

• Rome Fiumicino
• Vienna
• Dublin
• Billund
• Malta
• Palma de Mallorca
• Krakow
• Several airports in the United Kingdom

The Spanish example shows why travelers still need to check carefully. Palma de Mallorca is among the airports where the system is reported to be fully operational, while Malaga has a more limited implementation and other major Spanish airports continue to follow traditional limits.

That difference matters if you are connecting through Spain or flying home from a different airport than the one you used on the outbound journey.

Why return flights can catch travelers out

The new rules are useful, but they create an easy trap. You might depart from an airport where a full-size bottle of shampoo, sunscreen or perfume is allowed through security, then return from an airport that still applies the 100ml limit.

In that situation, the item that was acceptable on the first flight could be confiscated before the return flight if it does not fit the local rule.

Connections can create the same problem. If you have to clear security again during a transfer, the rules at the connecting airport matter too. A bottle bought or carried through one airport may not be accepted at the next checkpoint.

For now, the safest packing habit is to think about every airport on the itinerary, not just the first one.

What to check before you travel

Before deciding to leave the travel-size bottles at home, check the official security guidance for:

• Your departure airport.
• Any connecting airport where you may pass security again.
• Your return airport.
• The exact terminal, if the airport publishes terminal-specific rules.

It is also worth checking the airline's guidance, but airport security rules are usually the deciding factor. Airlines may explain the general policy, while the airport determines what happens at the checkpoint.

If the information is unclear, pack as if the 100ml rule still applies. That is less convenient, but it avoids losing liquids at security.

What this means for toiletries and electronics

For many travelers, the biggest benefit will be simpler packing. If your airport allows the relaxed system, you may be able to carry normal-size toiletries, sunscreen, cosmetics or contact lens solution in cabin baggage.

The technology can also reduce the need to separate electronics. At equipped checkpoints, laptops, tablets and liquids may be able to stay inside your bag. That makes the process quicker, especially for families, business travelers and anyone carrying several devices.

Still, passengers should follow the instructions given at the airport on the day. Staff may ask for items to be removed even when the newer scanners are in place, especially during transitional periods.

A practical packing approach

Until the rollout is more consistent, the best strategy is flexible.

If you are taking checked luggage, put full-size liquids there and keep only essentials in your cabin bag. If you are traveling hand-luggage only, use 100ml containers unless you have confirmed that every relevant airport accepts larger liquids.

For sun destinations, pay particular attention to sunscreen. It is one of the easiest items to forget when thinking about the 100ml limit, and it is also one of the most useful to have on arrival.

For short city breaks, the simplest option may still be a small transparent liquids bag. For longer trips, the relaxed rules can be helpful, but only if the return journey works under the same rules.

Bottom line

Europe's airport liquid rules are beginning to loosen in places where approved CT scanners are operating. That is good news for travelers, but it is not yet a universal rule.

For now, treat the 100ml limit as the default unless you have checked your exact airports and terminals. The new system may make security easier, but the old travel bottles are not quite ready for retirement.
