Zurich Airport Increases Hand Luggage Liquid Limit to 2 Liters

From June 26, 2026, security screening will be significantly simplified for some passengers departing from Zurich Airport: passengers departing locally and screened at the central Security Control Building may carry liquid containers of up to 2 liters in their hand luggage, and electronic devices no longer need to be removed from their bags. This change may also be important for Hungarian travelers, but it is not a general European rule: separate restrictions may still apply to transfer passengers, other airports, and certain special items.

According to a recent announcement from Zurich Airport, the modification is related to a comprehensive modernization of the airport's security screening. The essence is that traditional X-ray machines in the central control building are being replaced by new hand luggage screening systems based on CT technology. These create three-dimensional images of the package contents, allowing the examination of liquids and electronic devices to be performed with less manual unpacking.

The change is striking because for nearly two decades, the rule based on 100 milliliter containers and a 1-liter transparent, resealable bag has determined what we can take on board in hand luggage at most European airports. Zurich is not simply introducing a convenience detail, but is moving in a direction that several large airports may follow as properly certified CT equipment and adjusted screening processes become available.

What exactly is changing in Zurich?

The most important change is that from June 26, 2026, passengers who start their journey in Zurich and pass through screening at the main security control building may keep liquid containers with a capacity of up to 2 liters in their hand luggage. They do not need to pack liquids in a separate plastic bag, and laptops, tablets, cameras, chargers, or other electronic devices do not need to be automatically removed from the bag.

In practice, this means that a passenger departing from Zurich can, for example, take a larger cosmetic bottle, drink, or other liquid through security, provided that the given container does not exceed 2 liters and the item is otherwise permitted based on security rules. According to the airport's information, liquids and electronic devices may remain in hand luggage in all screening lanes in the Security Control Building area.

One goal of the modification is faster and less stressful screening. When passengers do not have to unpack their luggage into multiple trays, there are fewer movements causing congestion, a lower risk of items being mistakenly left behind, and queue management becomes simpler. This can be especially expected during the summer peak, when even a minor disruption at airports can ripple through multiple flights and many transfers.

Why is the new rule being introduced now?

Since the end of 2025, Zurich Airport has been gradually transforming its central security screening lanes to the new CT technology. According to the airport's communication, the project has reached its final stage: traditional screening equipment is being removed from the system, and all 26 lanes in the central control building operate with the new technology.

CT scanners do not just provide a sharper image, but enable spatial analysis. This helps screeners identify liquids, electronic devices, and other items in hand luggage more accurately. In the aviation industry, this is considered a major step forward because one of the slowest points of security screening has long been the separate handling of liquids, laptops, and other devices.

It is important, however, that the relaxation of rules is not merely a matter of an airport decision. Within European and national regulatory frameworks, the gradual easing of liquid restrictions depends on the availability, certification, and actual installation of appropriate equipment. Therefore, it may happen that on the same route, screening is much more convenient at one airport, while the old 100 milliliter rule still applies at the other.

Why is this important for Hungarian travelers?

Zurich is not only a destination for visiting the Swiss city but also an important European hub. From Hungary, Budapest-Zurich flight tickets and Vienna-Zurich flights offer many travelers direct or conveniently combinable access to Switzerland, as well as onwards to North America, Asia, or other European destinations. For those departing from Zurich Airport to go home or further, the change in hand luggage rules can be a real convenience advantage.

From the perspective of Hungarian travelers, the biggest advantage is more predictable packing. During a short Swiss business trip, family visit, or city tour, many travel with hand luggage only. For them, the amount of shampoo, sunscreen, contact lens solution, perfume, medicinal liquid, or drink often required separate planning. Departing from Zurich, this part can be simpler, but only if the passenger actually passes through the screening point applicable to locally departing passengers.

For business travelers, leaving electronic devices in the bag is at least as important. Along with laptops, company phones, power banks, chargers, and documents, security screening can easily become a fragmented, time-consuming process. The new Zurich system simplifies this situation, while the airport emphasizes: passengers must still allow enough time for screening, meaning early arrival recommendations do not cease.

The easing does not apply to all passengers

The most important point of caution is the transfer. Zurich Airport specifically notes that the security screening areas for transfer passengers and certain special processes do not yet operate with the same new CT technology. At these points, the usual restriction remains in effect: liquids may be carried in containers of up to 100 milliliters, in a transparent, resealable bag of up to 1 liter.

This is essential because many Hungarian travelers do not start their journey in Zurich, but arrive from Budapest or Vienna and then fly further. If another security screening occurs during the transfer, one should not automatically assume that the 2-liter Zurich rule applies. The same is true on the return journey: if someone flies from Zurich to another country and then departs from there to go home, the other airport's own liquid rules will be governing.

The airport specifically warns about double-walled bottles, such as thermoses. These can only be taken through security empty, because the multi-layered structure can make the reliable identification of the contents difficult. This may seem like a small detail, but many people carry heat-retaining bottles on a summer trip, so it is worth paying attention to this during packing.

Another special exception is analog photo film. CT equipment can damage sensitive films, so the airport advises those carrying such items to proactively present them and request a separate manual screening. This may be important primarily for photographers, those with a film hobby, or those departing for professional work.

What is worth doing before departure?

The Zurich easing is good news, but it does not replace the pre-departure check. Those traveling to Switzerland should first check exactly which airport and which terminal process they are departing from. If planning the trip from Budapest, it is advisable to separately check the current departure information of Budapest Airport, and if flying from Vienna, the flights and packing rules of Vienna Airport.

If Zurich is the destination, it is worth paying attention not only to the security screening but also to the logistics after arrival. The city is quickly accessible, but for late evening arrivals, large luggage, or family travel, it may be useful to think ahead about Zurich airport transfers, or for early departures, accommodations near Zurich Airport. The easing of hand luggage rules may provide a more convenient departure, but it does not solve all travel organization issues.

• Do not assume that the 2-liter rule is valid at all airports.
• In case of transfer, check if there will be another security screening.
• Carry thermoses and other double-walled bottles through security in Zurich only when empty.
• Present analog film separately and request manual screening.
• Continue to adhere to the airport's recommended arrival time.

The larger trend: more convenient, but more uneven airport rules

Zurich's move fits into the international trend where airports strive to reduce the administrative and physical burden on passengers while maintaining security. With the spread of CT scanners, the separate unpacking of liquids and electronic devices may become unnecessary in more places, but this process does not happen simultaneously in every country and every terminal.

For travelers, therefore, a transitional period follows. At one airport, they may be greeted by modern, faster screening, while at the next transfer point, the same old bag rule they have been used to for years. The biggest risk is not that screening will be stricter in Zurich, but that someone interprets the Zurich easing as a general rule and must throw away larger liquids at another airport.

From a Hungarian traveler's perspective, the good strategy now is cautious flexibility. If the journey starts from Zurich, the new opportunity can be used. However, if multiple airports, separate tickets, transfers, or return screenings are part of the itinerary, it is worth packing according to the strictest expected rule. This is especially true if traveling with hand luggage only and there is no possibility to put the problematic liquid in checked luggage.

What does all this mean for the summer travel season?

During the summer peak period, any change that reduces the time spent at security screening and the uncertainty developing in the queues counts. Zurich's new rule does not guarantee that there will never be waiting, nor does it exempt one from arriving on time. Still, it is a tangible relief for those departing from Switzerland, and who previously prepared for security screening specifically because of liquids or electronic devices.

Another message of the change is that the airport travel experience in the coming years will develop not only with new routes and greater capacity, but also with background processes. A faster screening requiring less unpacking is particularly valuable for those who fly frequently, depart on short business trips, travel with families, or try to make a tight connection. Zurich has now taken a visible step forward in this regard.

The practical conclusion for Hungarian travelers is simple: departing from Zurich, from June 26, 2026, more liquids can be carried in hand luggage, but only within the precisely defined screening circle. Those who handle this consciously can expect a more convenient departure. Those, however, who involve multiple airports, must continue to check the rules valid at every point of the route, because liquid restrictions in Europe will not be completely uniform for a long time.
