On Monday evening, authorities at Copenhagen and Oslo airports appeared to face their worst nightmare scenario, as multiple drones entered their restricted airspaces and hovered for over two hours, forcing officials to ground all flights and creating chaos at both airports. Both drones hovering over Copenhagen and ignoring the 5km exclusion zone around Oslo set off a wave of flight cancellations and delays. In Scandinavia, the dangling passengers had to be surprised, as they were suddenly shifted to northern and eastern Sweden for onward travel. The relative ease of drone use paired with the ability to breach airspaces which are crucial to international flights and travel raises a lot of strong security issues.
In a series of highly disruptive events, both Copenhagen and Oslo Airports were forced to ground all air traffic due to multiple drone incursions that significantly affected travel across Scandinavia on Monday evening. These incidents led to flight delays, cancellations, and diversions, disrupting the schedules of thousands of passengers. Authorities are investigating the source of these incursions, but as of now, the identity of the drone operators remains unknown. The disruptions have raised critical questions regarding airport security, the growing threat of drone activity near major airports, and the impact on passengers and airlines.
A Chaotic Evening at Copenhagen Airport
Copenhagen Airport, the largest travel hub in Scandinavia, experienced an extraordinary level of disruption on Monday night when several large drones were sighted hovering over its airspace. This led to a complete shutdown of all operations for over four hours, grounding flights and diverting others to neighboring airports, including in southern Sweden and parts of Denmark. Witnesses described the drones as being equipped with flashing lights, further complicating the situation and causing widespread concern. The presence of these drones, hovering intermittently for over two hours, prompted immediate action from local authorities.
The closure of Copenhagen Airport brought air traffic to a standstill, with hundreds of flights delayed or diverted. Passengers were forced to wait in uncertainty, with minimal information provided as authorities scrambled to identify and neutralize the potential threat. Despite extensive efforts, no drones were brought down, and no arrests were made. Copenhagen’s Chief of Police confirmed that the drones disappeared on their own, leaving questions about the effectiveness of current airport security measures in dealing with such incidents.
Similar Disruptions in Oslo
The chaos continued as Oslo Airport, Gardermoen, experienced a similar intrusion. Just as Copenhagen was reopening to air traffic, Oslo Airport was grappling with its own drone-related crisis. The situation worsened around midnight when drones breached the airport’s 5km exclusion zone, causing officials to close most of the runways and operate with just a single runway. The threat from the drones forced authorities to ground flights temporarily, leaving thousands of travelers in limbo.
The situation at Oslo Airport mirrored that of Copenhagen, with multiple flights being redirected to other airports and significant delays experienced by those still in the air. However, by the time the second wave of drone sightings was confirmed, Oslo was also forced to shut down completely. Flights that were already in the air were diverted, and many were forced to return to their point of origin, causing frustration among passengers who found themselves stranded in the skies.
Most Affected Routes at Oslo Airport (Gardermoen)
Based on the airlines listed and their general routes, the following are likely the most disrupted routes at Oslo Airport:

This breakdown reflects the specific routes that were most likely impacted by the drone incursions at both airports. The data provided earlier indicated significant delays and cancellations across these routes, especially those operating by high-volume carriers like SAS and Norwegian Air Shuttle.
Major Impact on Airlines
Both Copenhagen and Oslo Airports are vital for many international and domestic airlines, and the drone disruptions severely impacted their operations. The number of cancellations and delays reported was staggering. In total, Oslo experienced 104 delays and 11 cancellations on the day of the incident, as reported by FlightAware.
Airlines such as SAS, SAS Link, Norwegian Air Shuttle, and easyJet were among those most affected, with significant delays impacting travelers’ schedules. In the aftermath of the drone incursions, travelers faced delays of up to several hours, and cancellations disrupted their travel plans. The massive volume of diversions further added to the congestion at surrounding airports, straining available resources and creating a ripple effect throughout the Nordic region’s airspace.
At Copenhagen, the situation was similarly dire, with 214 delays and 77 cancellations reported. SAS and Norwegian Air Shuttle were among the hardest-hit airlines, with dozens of flights affected. In addition to flight cancellations, numerous flights were delayed, and passengers were diverted to nearby airports, exacerbating the congestion at neighboring airports. The ripple effect of the disruption continued for several hours as airlines worked to rebook passengers and mitigate the ongoing impact.
The drone-related incidents resulted in significant operational challenges for these airlines, and the logistical headache of rebooking and rerouting flights led to widespread frustration among travelers. Furthermore, airlines such as Lufthansa, Air France, and easyJet reported that their flights were affected by the delays and diversions, adding to the strain on air travel in the region.
Passenger Impact and Stranded Travelers
The most significant impact was felt by passengers who found themselves caught in the chaos. With flights delayed, canceled, or diverted, thousands of travelers were left stranded in airports or rerouted to alternative locations. Many passengers faced confusion and anxiety as they waited for updates from their airlines, with little information provided about the situation on the ground.
One particularly affected passenger described how his flight from Rome was diverted over 275 miles to Stavanger, only to learn that the airport in Oslo had shut down due to drone activity. The frustration among passengers was palpable, as many were forced to wait for hours without clear communication from their respective airlines. With no indication of when normal operations would resume, many passengers were left wondering how their travel plans would be affected in the coming days.
The diversion of flights caused by the drone incursions was not limited to just a few airlines. Multiple carriers had to adjust their operations, which led to further confusion and long waits for passengers. As delays mounted, passengers were left with no choice but to endure the inconvenience and uncertainty brought on by the unexpected shutdowns of the airports.
Investigation and Ongoing Efforts
Authorities in both Denmark and Norway have launched extensive investigations to determine the origin and intent behind the drone activity. At Copenhagen, local police were unable to capture the drones or identify their operators, but they did confirm that the drones had disappeared without being intercepted. The Danish authorities have not released further details on their efforts to track down the operators, but they continue to work in conjunction with Norwegian authorities to determine whether the two incidents were connected.
Given the severity of the disruptions, both countries are likely to reevaluate their security protocols around airports to address the increasing threat posed by drone activity.
