Disruption details

Passengers flying through Copenhagen Airport faced disruption on 4 June 2026 after Scandinavian Airlines (SAS), CityJet, and Norwegian Air Sweden canceled 6 flights and delayed 34 more. In total, 40 flights were affected over the course of the day.

For passengers, this meant missed connections, longer waits, and a frustrating day of travel. Because Copenhagen is one of Scandinavia's main hubs, even a relatively small number of cancellations quickly spread through airline networks.

The disruption affected each airline differently:

• SAS canceled 3 departures and delayed 19 other flights.

• CityJet canceled 2 flights and recorded 9 delays.

• Norwegian Air Sweden canceled 1 flight and delayed 6 more.

On paper, this was only a small share of daily flying, roughly 1% of SAS's schedule and 2% of CityJet's. But at a hub like Copenhagen, even limited disruption can quickly cascade into missed connections and late aircraft rotations.

More than 30 destinations felt the knock-on effects, including Hamburg, Munich, Helsinki, London, Amsterdam, Oslo, Brussels, Paris, Athens, Vienna, and Zurich. Secondary Scandinavian airports such as Aarhus, Billund, Bergen, Stavanger, and Trondheim were also affected, alongside longer-haul points including Newark, Tokyo, and Bangkok.

The impact didn't stop with the canceled flights themselves. Rolling delays also reached Gdansk, Riga, Vilnius, Split, Malaga, Nice, Istanbul, Faro, Porto, Lisbon, and Luxembourg, making the disruption much wider than a single airport terminal issue.

Business and leisure travelers were both caught up in the disruption, and some passengers described multi-hour waits to rebook at Copenhagen Airport. By the evening, airlines were still adjusting schedules in real time to get operations back on track.

The episode appears to have remained a one-day event, ending later on 4 June rather than spilling into 5 June. The exact trigger, however, was not confirmed. There was no reported strike or weather alert, and the disruption was treated as a localized airport issue without a clear public explanation.

All 3 airlines told passengers to keep checking their apps and websites for rerouting information and timetable updates. For anyone with a connection through Copenhagen, that likely meant watching for changes right up to departure.

If your flight was affected, what you're entitled to will depend on what caused the disruption. If the issue turns out to have been within the airline's control, some passengers on eligible routes may still be covered by EC 261. If it was caused by severe weather or another problem outside the airline's control, compensation is less likely.

Either way, airlines should still help with rerouting or refunds, and provide food, drinks, and accommodation when required during longer disruptions. If you want to understand what applies to your trip, you can check your flight with AirHelp's free flight checker.
