Travellers in Spain could face fresh airport disruption from Friday after air traffic controllers at Saerco-run towers called an indefinite strike affecting 14 airports across the country.
The strike is due to begin at 00:00 on 17 April, according to USCA and CCOO, the unions behind the action. They say the dispute is not over a one-off incident, but over what they describe as a long-running staffing and working-conditions problem affecting privately managed control towers.
Which airports are affected?
Spanish reporting says the strike affects controllers working in Saerco-managed towers at:
Madrid-Cuatro Vientos, Lanzarote, Fuerteventura, La Palma, El Hierro, La Gomera, Castellón, Burgos, Huesca, Ciudad Real, Vigo, A Coruña, Jerez and, Sevilla.
For UK and Irish travellers, the most relevant names on that list are likely to be Lanzarote, Fuerteventura, La Palma, Sevilla, Jerez, Vigo and A Coruña, depending on routes, connections and airline schedules.
Why controllers are striking
USCA and CCOO say the strike has been called over staff shortages, worsening working conditions and what they describe as risks to operational safety. The unions claim Saerco has reduced staffing over time without properly replacing departing workers, leaving the remaining workers to cover operations under increasing pressure.
Their complaints include cancelled holidays, excessive use of availability, short-notice shift changes, unclear rest planning and irregular organisation in several workplaces. The unions argue that fatigue, stress and uncertainty are incompatible with the concentration required in air traffic control.
Could flights be cancelled?
At this stage, travellers should treat the situation as a disruption risk, not a guarantee that flights will be cancelled.
Minimum services are normally set for strikes affecting essential services, and negotiations or mediation can still change the situation before the strike begins. Cadena SER reported that the Galicia dispute remained subject to last-minute talks, with a key meeting scheduled before the 17 April start date.
Even so, the timing is awkward. Mid-April is a busy travel period, and several of the affected airports serve holiday routes, island travel and regional connections. Any reduction in capacity, staffing flexibility or tower availability could create delays or schedule changes.
What passengers should do now
Passengers due to travel through one of the affected airports from 17 April onwards should check their airline’s app or website before leaving for the airport. They should also allow extra time, keep an eye on airport notices and avoid relying only on older booking emails.
If a flight is delayed or cancelled, passenger rights will depend on the cause, timing and airline response. Travellers should keep receipts for extra expenses, save screenshots of airline messages and ask the airline for written confirmation of the reason for any disruption.
A wider spring travel headache
The possible air traffic control strike comes at a time when travellers are already dealing with tighter border checks, Easter-season pressure and wider concerns about disruption across European airports.
For Spain, the dispute also raises a bigger question about privately managed airport control towers and whether staffing levels are keeping pace with demand. For passengers, though, the immediate message is simpler: if you are flying through one of the 14 affected airports from Friday, check before you travel and be prepared for possible delays.
