Drone Incursions Disrupt Copenhagen & Oslo Flights
Unauthorized drone incursions on September 23, 2025, forced the diversion of 30+ flights at Copenhagen Airport and Oslo Airport, disrupting travel across Northern Europe.
On September 23, 2025, air traffic at Copenhagen Airport (CPH) and Oslo Airport (OSL) was interrupted after authorities detected unauthorized drone activity near both aerodromes. The incidents led police and aviation officials to temporarily suspend arrivals and departures as they investigated, causing cascading delays and rerouting of domestic and international services.
More than 30 flights were diverted between the two hubs, and thousands of passengers experienced delays and cancellations. No injuries or collisions were reported. Airlines and ground handlers scrambled to rebook affected passengers while authorities worked to secure the airspace.
Why drone incursions matter
Drone incursions threaten safety around critical infrastructure: small unmanned aircraft can interfere with takeoffs, landings and radar systems, and they complicate air traffic control decisions. The September 23 events highlighted persistent regulatory and technological gaps in detecting and mitigating rogue drones near major European airports.
- Authorities promise stepped-up surveillance and enforcement to prevent further drone incursions.
- Airports are reviewing detection and mitigation systems and coordinating with police and aviation regulators.
- Passengers affected by diverted services faced rebooking and onward travel delays while airlines processed refunds and accommodation where required.
Danish and Norwegian officials said they will evaluate improvements to drone detection, no-fly zone enforcement and rapid-response protocols. The incidents serve as a reminder that as consumer drone ownership grows, airports must accelerate investment in counter-drone systems and clearer regulations to protect commercial flight operations.
For travelers, the near-term takeaway is to expect that airports in the region may introduce new restrictions and be prepared for last-minute changes while authorities tighten oversight. Airlines and airports are also likely to publish guidance on drone-related disruptions as investigations conclude.
