Drone alarm at Copenhagen Airport: Chaos in air traffic!

On Monday evening, September 23, 2025, Copenhagen Airport experienced a four-hour state of emergency due to the sighting of several drones over the airport premises. Air traffic was suspended from 8:26 p.m. local time and it was not possible for aircraft to take off or land. This drastic measure resulted in numerous flights being canceled or delayed and dozens of aircraft being diverted to other airports such as Malmö, Billund, Aarhus and Gothenburg. Only one plane was able to land around 9:30 p.m. because it could no longer be kept in the air due to a lack of fuel.

The police immediately responded to the sightings with a large contingent and initiated an investigation into the drones. Between two and four large drones have been spotted over the airport grounds, but there is currently no information on the origin or purpose of these drones. The airport press spokeswoman expressed the urgent interest in quickly clarifying the situation in order to resume normal operations. All air traffic remained suspended until after midnight, with the first flight after reopening being SK7744 at 12:37 a.m.

Impact on air traffic

The sighting of drones had a massive impact on air traffic at Copenhagen Airport. Over 35 flights were diverted due to the drone sightings. The police stated that it was still unclear when the operation could be ended. According to information from Merkur, no confirmed links to previous incidents in Europe that may have been linked to Russia have been identified. This uncertainty creates additional tension among passengers.

The incident highlights a growing problem that is also affecting other European airports. Fraport reports that drone flights pose serious threats to the safety of air traffic and can cause economic damage. Airport operators and security authorities are working intensively to detect drones at an early stage and take appropriate countermeasures.

This year, police authorities have already arrested several drone pilots and initiated proceedings. Drone sightings in security areas, such as at Frankfurt Airport, should be reported immediately to the Fraport AG security emergency number or the police. The incident in Copenhagen highlights the need for strict surveillance and security measures to ensure aviation safety.

Passengers at Copenhagen Airport were asked to contact their airlines to find out about possible flight cancellations and to note the current situation.
