New Security Check Opened at Copenhagen Airport: What Does This Mean for Hungarian Travelers in Summer 2026?

Copenhagen Airport opened its new security check zone on May 19, 2026, where 20 new CT scanner lanes are now in operation. At first glance, this may seem like a local airport improvement, but in reality, it is about much more: one of Northern Europe's most important transit hubs is switching to a faster, more predictable, and more passenger-friendly process just before the summer peak season. This is important news for Hungarian travelers, especially those flying via Copenhagen to Scandinavia, North America, or Asia.

The most significant change is that screening hand luggage on the new lanes is becoming simpler: electronic devices do not need to be taken out of the bag, and it is also easier for passengers as watches, belts, and shoes can remain on. However, there is one very important restriction: the liquid rule is not being relaxed for now. Despite the new technology being capable of handling larger containers, the classic 100-milliliter rule remains in effect in Copenhagen until EU approval is received.

In other words, the real significance of the news is not that "everything is now allowed," but that a high-traffic airport is attempting to speed up passenger flow without stepping outside current EU regulations. From the perspective of Hungarian travelers, this is a particularly useful development, as many seek transit airports during the summer period where not only many flights are available, but the departure experience is also less stressful.

What Exactly Changed in Copenhagen?

The new security check at Copenhagen Airport is based on CT technology. This system creates a three-dimensional image of the hand luggage contents, meaning the screening can be more detailed and efficient without passengers having to unpack so many items from their bags. According to the airport, the new lanes can process up to one-third more passengers per hour than previous checkpoints.

This is not just a matter of convenience. Security screening is one of the most sensitive points at most large European airports: if a bottleneck forms here, it quickly ripples through the entire terminal, increasing uncertainty and forcing passengers to arrive at the airport earlier. Copenhagen is now signaling to the market that it is providing capacity and a more transparent process for passengers before the start of the summer season.

The physical layout of the new screening zone also serves this purpose. The lanes are longer, more passengers can pack simultaneously, and the detailed scanning of hand luggage takes place in a separate area where security staff can examine the 3D images under calmer conditions. This background process is less visible to the passenger, but it is precisely because of this that the entire screening can be faster and more stable.

What Has Not Changed: Liquids Must Still Be Monitored

Many automatically assume that if CT scanners appear at an airport, the 100-milliliter restriction also disappears. The example of Copenhagen warns that this is not so simple. The airport has publicly stated: the system is technically ready to handle larger quantities of liquids, but EU authorization has not yet been finalized. Therefore, current rules remain.

In practice, this means that Hungarian travelers must continue to prepare in the same way as at other large European airports. Liquids in hand luggage can only be carried in containers of up to 100 milliliters, and these must be kept in a transparent, resealable, plastic bag of up to one liter. Anyone who thinks that they can now bring larger drinks, cosmetics, or sunscreen due to the new technology may easily encounter an unpleasant surprise at the checkpoint.

This is especially important for transit passengers. According to Copenhagen Airport's own information, if someone arrives from outside the EU and continues their flight, they may undergo security screening again, and in such cases, the liquid rules apply equally. In other words, the new system is more convenient, but it does not mean that the passenger can forget basic packing rules.

Why Is This Important Now, Just Before Summer?

Timing is key. Copenhagen is not a secondary regional airport, but one of the defining hubs of North European air travel. In the first quarter of 2026, the airport handled seven million passengers, representing a 14 percent annual increase. Nearly two million of these were transit passengers, and today 28 percent of all passengers continue their journey via Copenhagen to their final destination.

This figure is important because it shows that Copenhagen's operation is not just about Danish inbound and outbound traffic. An increasing proportion of passengers arrive at the airport for whom every minute counts due to their connection. If security screening becomes more predictable, it is not only good for those traveling to Denmark, but also for those changing flights there, for example, on Scandinavian, North American, or Asian routes.

The growth continued in April: the airport handled 2.8 million passengers, which was the strongest April result ever in Copenhagen. The increase in traffic is partly linked to the expansion of international routes. The airport specifically highlighted that demand toward Asia is strengthening, with new connections to Shanghai and Ho Chi Minh City appearing, and the number of flights to Seoul has increased. This further strengthens Copenhagen's role as a hub that is increasingly attractive not only for city visits but also for long-distance transit.

Why Could This Be Interesting for Hungarian Travelers?

From a Hungarian perspective, Copenhagen is not the primary starting point for everyone, but it is relevant in several situations. Firstly, many fly to the Danish capital for sightseeing or business trips; secondly, the airport is an important gateway to Scandinavian loops, fjord or North Sea vacations, and more distant connections. If someone plans a trip starting in Denmark or a transit in Copenhagen, the new screening system can be a tangible benefit.

For the Hungarian passenger, the real gain is not simply saving a few minutes. Rather, it is that there is less uncertainty at the security point, and there is a lower chance that on a crowded summer day, the screening will be the most frustrating part of the trip. This is especially important if someone is traveling with a shorter connection time, flying with children, or wants to pass through the terminal as simply as possible with hand luggage.

Another important aspect is that Copenhagen is perceived by many travelers as a "quality transit airport." Competition between such airports today is not just about routes, but also about how seamless the passenger feels the entire process from entry to the gate. The new screening zone points exactly in this direction: the airport does not just want to handle more flights, but also wants to provide a less stressful passenger experience.

What Should Those Traveling via Copenhagen Recently Pay Attention To?

The best strategy now is still disciplined preparation. Because of the new system, security screening may indeed be simpler, but one should not assume that all rules have changed. Electronic devices can remain in the bag, which is more convenient, but the old restriction on liquids still applies. Those who know this in advance can save themselves a lot of inconvenience.

• If you are flying from Copenhagen, it is still worth preparing hand luggage according to the classic 100-milliliter rule.
• If you arrive from outside the EU and transit in Copenhagen, expect that your hand luggage may be screened again.
• For travel within Schengen, the airport recommends arriving at least 2 hours before, and for travel outside Schengen, at least 3 hours before.
• It is worth monitoring real-time airport information and airline notifications, especially on peak summer days.

If someone plans a longer stay in Copenhagen, it may be useful to review the Copenhagen CPH airport page, or depending on the nature of the trip, accommodation near the airport, transfer and taxi options, or car rental options. These are particularly useful if the passenger is not just transiting, but spending one or more nights in Copenhagen.

The Bigger Picture: Not Just a Convenience Improvement

Copenhagen's new security check also shows where the large European airports are heading. Passenger numbers are increasing, and transit traffic is strengthening; competition is increasingly about reliability and passenger experience. In this environment, modernizing a security point is not a technical detail, but a strategic tool. If the airport can process passengers faster and more stable, it becomes more attractive to airlines and transit passengers alike.

This development also comes at a time when the entire aviation sector continues to be burdened by external risks. Copenhagen Airport itself has indicated that it is monitoring the geopolitical situation and the trend of fuel prices. In other words, the conditions of the aviation market are not entirely calm, and improving passenger-side processes is therefore even more important: the airport is trying to improve what it can stabilize within its own jurisdiction.

Summary

Copenhagen Airport's new security check with 20 CT scanners is a real, practical improvement before the 2026 summer season. For passengers, the process can be more convenient, electronic devices do not need to be unpacked, and according to the airport, the system can handle up to one-third more people per hour. This is especially important at a hub where transit traffic is growing rapidly.

The most important lesson, however, is that ease of process does not equal full deregulation. The 100-milliliter restriction on liquids remains for now, therefore Hungarian travelers must continue to prepare consciously. For those who understand this, Copenhagen can indeed be a faster and less stressful gateway to Denmark, Scandinavia, or more distant destinations this summer.
