Air traffic controller strikes will cause ‘indefinite’ disruption to flights from April 17, affecting some of the most popular European holiday locations

British holidaymakers are facing the prospect of indefinite disruption starting from tomorrow at major European holiday destinations. A total of 14 airports at popular holiday locations are preparing for strike action from Friday, April 17.

Air traffic controller unions are warning that the strike action is ‘indefinite’. Spanish media reports indicate that the action by USCA kicks off on April 17 at the Canary Island hotspots of Lanzarote, Fuerteventura, La Palma, La Gomera and El Hierro – with nine further locations also affected.

Other popular holiday destinations set to be hit by airport strikes include the mainland locations of Jerez de la Frontera, La Coruña, Madrid-Cuatro Vientos, Vigo and Seville. Castellón, Burgos, Huesca and Ciudad Real are also set for strike action.

Travel website Travel On World is cautioning tourists that the greatest risk is likely to be “delays, late aircraft rotations, missed connections and short-notice timetable changes.”

The site notes that for many travellers, the main concern is not a complete shutdown of operations. Instead, it is planes departing late from earlier locations, inbound flights being held up, departure slots changing around, turnaround times tightening and passengers having to put up with long waits for clear details on what is happening.

Because air traffic control is classed as an essential service, Spanish authorities have the power to impose minimum service levels. This should mean that some flights continue to operate.

Some flights are therefore likely to depart close to schedule. Yet others may face significant delays, and some could be cancelled where airlines determine the knock-on effect has become too serious.

What are my rights over the Spain airport strikes?

According to the Civil Aviation Authority, if your UK flight is delayed, and a post-Brexit regulation known as UK261 applies to it, your airline must care for you while you are delayed. This includes supplying you with food and drink depending on the length of your delay, and accommodation if you are delayed overnight.

You may also be entitled to compensation if the delay results in you reaching your destination airport more than three hours late. If the delay exceeds five hours, you can opt not to travel and receive a refund.

What is the Spain strike action all about?

The airports affected by the industrial action share a common thread – all are operated by SAERCO. Further strikes had previously been anticipated at Lanzarote and Fuerteventura, linked to a separate ongoing dispute involving Groundforce baggage handlers. However, it emerged earlier this week that this action has now been suspended.

Travellers must now contend with this latest wave of industrial unrest. Air traffic control unions say they are taking strike action over staff shortages and shift scheduling disputes – and passengers should be ready for disruption.

USCA spokesman José Luis Feliú told El Espejo Canario that delays are a real possibility. And the sunspots are busy all year long. Aena reports that 5.7million British holidaymakers visited the Canary Islands in 2023 alone.

Even outside of the school holidays, the islands remain a firm favourite with British travellers – and for good reason. According to the Hello Canary Islands website, with 4,800 daylight hours a year, the Canary Islands have the most daylight hours of anywhere in Europe.

What the unions are saying about the Spain airport strikes?

USCA spokesman José Luis Feliú told Spanish media there is currently a “shortage of air traffic controllers,” which he said directly impacts the system’s operation. “It generates greater stress, more fatigue, and makes it impossible to guarantee service continuity,” he warns.

The union spokesman highlights that the surge in air traffic has worsened the situation, compelling professionals to shoulder heavier workloads under increasingly difficult conditions, reports El Espejo Canario. One of the most pressing concerns is shift management, he alleges. “The company unilaterally changes the schedule,” alleges Feliú, leaving workers unable to plan their personal lives, he claims.

He claims that air traffic controllers are forced to “give up leave, vacations, and planned changes,” a situation he regards as unsustainable in the long run. “In the end, you work the same hours, but without any planning,” he claims.

The strike is indefinite, although minimum services will remain in place, it is understood. Spanish website Larazon reports that the union cites “staff cuts of up to 33%” as the reason for this nationwide strike.

The website reports that the action is set to affect football fans using Seville airport. The Copa del Rey final will take place in Seville between Atlético de Madrid and Real Sociedad on Saturday, April 18.

According to Diario de Jerez, as of midday Thursday, the Jerez airport schedule still showed 18 commercial flights planned for Friday (nine landings and nine takeoffs). Meanwhile, another 18 commercial operations are scheduled for Saturday, two of them with Germany.

Ryanair is calling on passengers to act

Thousands of Ryanair flights have been cancelled, with the budget carrier continuing its campaign to “keep EU skies open”.

Ryanair has set up a a petition, aimed at the European Commission, to reduce the impact of French Air Traffic Control (ATC) strikes on EU flights. The campaign has now garnered support from more than two million people, with thousands of flights scrapped – and more disrupted – in 2025 alone. In October of last year, Ryanair CEO Michael O’Leary said: “It is inexcusable that Europe’s worst performing ATCs in France, Spain, Germany and the UK continue to inflict avoidable delays and cancellations on millions of EU citizens every month.

“Despite warnings, Europe’s ATC performance is not improving, as national providers fail to properly staff and manage their operations. EU ATC needs reform and its passengers who are paying the price.

“ATC delays have already disrupted 33m citizens so far this year, with France, Spain, Germany and the UK consistently failing to staff and manage their services properly.”

The International Air Transport Association (IATA) reported last month that Air Traffic Flow Management (ATFM) delays in Europe have “grown sharply” in recent years, with this “far outpacing traffic growth”. ATFM delays, it said, “have cost airlines and passengers an estimated EUR 17.5 billion since 2015 (in 2025 prices), of which over 70% is linked to capacity shortages and staffing issues”.

The Council of the European Union said last year that “the air traffic control system is increasingly struggling to manage this growing demand”, noting that while “close coordination has been underway for many months between the European Commission and EUROCONTROL as well as ongoing planning between the EUROCONTROL Network Manager, airlines, airports, air navigation service providers and the military … resolving the issue also requires political will at the national level as each country is responsible for providing adequate air traffic services and making the necessary investments to support these services.”
