Power outage and ground strike disrupt flights at Barcelona–El Prat Airport

Disruption overview

An electrical failure in the air-traffic-control tower at Barcelona–El Prat Airport around midday on 12 August 2026 forced a full halt to take-offs and landings during one of the busiest weeks of the summer. The outage lasted for several hours and upset aircraft and crew positioning for the rest of the day, leading to cancellations, gate holds, and diversions.

The disruption landed on top of an open-ended ground-handling strike that began on 4 August and affected check-in, baggage, boarding, and turnaround services. For passengers, that meant longer waits, missed plans, and more uncertainty across Spain and the wider European network. Because the causes appear to have been outside the airline's control, compensation is usually unlikely, but airlines should still provide rebooking or refunds, as well as care and assistance during long or overnight delays.

Disruption details

Flights at Barcelona–El Prat Airport were heavily disrupted on 12 August 2026 after an electrical failure in the air-traffic-control tower stopped take-offs and landings around midday. The problem hit during the August holiday rush and piled extra pressure onto an open-ended ground-handling strike that has been running since 4 August.

Operations were suspended for several hours while engineers switched the tower to back-up systems. Even after flights started moving again, the airport did not return to a normal flow for the rest of the day. Aircraft and crews were left out of position, and airlines had to manage cancellations, long gate holds, and diversions to secondary airports.

For passengers, this meant a difficult day of travel uncertainty. Dozens of services were canceled or rerouted, and delays carried on into the evening. Several thousand people flying on low-cost carriers alone were left stranded or had to rebook at short notice.

The tower outage made an already stretched situation worse. Since 4 August, ground-handling staff employed by El Prat's main ramp-service contractor have been on an indefinite strike. The walkout has affected check-in, boarding, baggage handling, and the turnaround work that helps keep aircraft moving on time.

Authorities in Catalonia have imposed minimum-service requirements, especially on lifeline routes to the Balearic and Canary Islands. Even so, airlines and passenger-rights groups have warned that travelers should expect slower processing, baggage delays, and last-minute schedule changes for as long as the stoppage continues.

The timing couldn't have been much worse. Over the long weekend around 15 August, Barcelona–El Prat Airport was scheduled to handle more than 3,300 flights. With operations already close to declared capacity, there was very little room to absorb a technical failure in the tower, which helps explain why the disruption spread so quickly.

The impact hasn't stayed in Barcelona. Elevated delay and cancellation levels have been recorded on Barcelona services in the days after 12 August, and other airports across Europe have felt the knock-on effects. Amsterdam Schiphol Airport has logged more than 120 cancellations so far this month, while Milan Malpensa Airport and Madrid–Barajas Airport have also seen problems as aircraft rotations and onward connections slipped. Some of the worst days have overlapped with the Barcelona disruption, alongside separate weather and capacity pressures.

Southern Europe has been under strain from more than one angle. Connections to Sicily have been especially vulnerable, and Mount Etna's ash emissions have periodically forced closures at Catania–Fontanarossa Airport this month. One large Iberian carrier has already moved its Catania flights to Palermo Airport until at least mid-August, tightening aircraft availability even further. Taken together, the technical failure, labor action, and volcanic disruption show how quickly summer schedules can unravel when major hubs are already operating near their limits.

Most airlines serving Barcelona have offered flexible rebooking or refund options. Consumer agencies in Catalonia have also stressed that airlines still have responsibilities to passengers even when the disruption involves subcontracted ground staff rather than the carrier's own employees.

If your flight was affected, your airline should still help with the essentials:

• A replacement flight or a refund if your flight was canceled and you no longer want to travel.

• Food and refreshments if you're left waiting for several hours.

• Hotel accommodation and transport to and from it if the delay runs overnight.

• Reasonable communication support during a long disruption.

Because the tower power loss and the wider ground-handling strike appear to sit outside the airline's control, compensation is usually unlikely in cases like this. But that doesn't mean you're without support. Under EC 261, care and assistance can still apply, and it's worth checking your options if your trip was disrupted.
