Storm Dave causes 238 cancellations and 1,469 delays across Europe

Disruption overview

Storm Dave disrupted flights across northern and western Europe on 7 April 2026, with at least 238 flights canceled and 1,469 more delayed at Keflavik International Airport, Stockholm Arlanda Airport, Dublin Airport, London-area airports, and Frankfurt Airport. Airlines affected included Icelandair, Scandinavian Airlines, easyJet, Cityjet, and Helvetic Airways, while knock-on delays spread to secondary airports as crews and aircraft fell out of position.

For passengers, that has meant long queues, missed connections, and difficult rebooking at already busy hubs. Because the disruption is being driven by severe weather, compensation under EC 261 is unlikely, but airlines should still provide care, rerouting, or refunds where needed, and AirHelp's free flight checker can help you understand your rights.

Disruption details

Storm Dave caused widespread flight disruption across northern and western Europe on 7 April 2026, with at least 238 flights canceled and 1,469 delayed at Keflavik International Airport, Stockholm Arlanda Airport, Dublin Airport, London-area airports, and Frankfurt Airport.

For passengers, this meant last-minute cancellations, long delays, and difficult rebooking at some of Europe's busiest connecting points. Queues built up in check-in halls and security lanes in Dublin, Stockholm, and London as travelers tried to rearrange plans or ask for hotel vouchers.

Some of the biggest pressure points were:

• Keflavik International Airport, where Icelandair's European and trans-Atlantic departures and arrivals were disrupted.

• Stockholm Arlanda Airport and Dublin Airport, where passenger traffic surged as people queued to rebook or ask for hotel vouchers.

• London-area airports, where easyJet, Cityjet, and other carriers faced knock-on delays as aircraft and crews fell out of position.

• Frankfurt Airport, where congestion slowed new departure slots, baggage transfers, and some onward connections.

The cause was straightforward: high winds, driving rain, and poor visibility linked to Storm Dave reduced runway capacity and forced air traffic control to leave more space between aircraft. European airspace stayed open, but airlines couldn't keep tightly timed schedules intact as missed slots and late arrivals quickly spread through the network.

Several airlines were named among the affected carriers, including Icelandair, Scandinavian Airlines, easyJet, Cityjet, and Helvetic Airways. Icelandair's hub operation at Keflavik was hit on both European and trans-Atlantic services, while Scandinavian Airlines canceled or retimed flights between Nordic capitals, London, and other major European cities.

For low-cost and regional operators, recovery has been harder because there is less slack in the schedule. easyJet has been dealing with packed rosters, and carriers such as Cityjet and Helvetic Airways have faced longer waits for new departure slots at congested airports including London and Frankfurt.

The disruption hasn't been limited to the airports under the worst weather. Secondary airports linked to those hubs have also seen knock-on delays as aircraft and crews were left in the wrong place, making it harder for airlines to get later flights away on time.

Frankfurt's connecting system has also felt the strain. Some passengers arriving late from North America have missed onward flights within Europe, while uneven arrival patterns have slowed baggage transfers. Even after the storm front moves on, disruption may linger because airlines still need to reposition aircraft and crew within working-hour limits and airport curfews.

With weather expected to affect conditions for at least 12 to 24 more hours, further short-notice cancellations and longer delays remain possible. If your flight is affected, it's worth checking your airline's app, asking for written confirmation of any cancellation, and keeping receipts for extra costs.

Because this disruption appears to be caused by severe weather rather than something the airline could control, compensation under EC 261 is unlikely. But airlines should still provide care and assistance, which can include rerouting or a refund after a cancellation, food and drinks during long waits, accommodation if you're delayed overnight, and communication support when needed.

Although compensation is unlikely here, that doesn't mean you're without support. If your journey has been disrupted, AirHelp's free flight checker is a simple way to understand your rights and see whether compensation could still apply in your specific situation.
