Air passengers heading to and from Spain for Semana Santa could face disruption from Monday, 30 March, after Groundforce workers confirmed an indefinite strike that is expected to hit major airports during one of the busiest travel periods of the year. Friday reporting from El País and Cadena SER said the dispute affects Groundforce operations at 12 high-traffic airports, including Madrid-Barajas, Barcelona-El Prat, Alicante, Valencia, Málaga, Bilbao, Palma de Mallorca, Ibiza, Las Palmas, Tenerife, Lanzarote and Fuerteventura.
The strike is due to take place in three daily stoppage windows, from 5.00 am to 7.00 am, 11.00 am to 5.00 pm and 10.00 pm to midnight, and unions say it will continue unless a deal is reached. The dispute centres on what unions describe as Groundforce’s failure to honour pay commitments under the collective agreement and its interpretation of salary updating rules linked to inflation since 2022.
Why this strike matters during Semana Santa
What makes this more than a routine labour story is the timing. Semana Santa is one of Spain’s most intense travel periods, and even minor disruptions in handling can quickly spill over into longer queues, baggage delays, and slower aircraft turnaround times. El País reported that the walkout covers around 3,000 workers. At the same time, the Transport Ministry’s minimum-services resolution shows the dispute reaches across a wider Groundforce network of work centres, underlining the scale of the operational challenge.
Which airports are affected by the strike?
The official minimum-services resolution also gives a broader sense of the strike’s footprint. The ministry document lists Groundforce centres in Barcelona, Madrid, Ibiza, Palma de Mallorca, Gran Canaria, Fuerteventura, Bilbao, Lanzarote, Alicante, Valencia, Zaragoza, Sevilla and Málaga, which suggests the impact could reach beyond the airports most prominently named in initial news reports. The same resolution says the airlines handled by Groundforce are scheduled to operate more than 8,400 movements across the strike period and that more than 1.34 million passengers could be affected, based on expected Easter demand.
That does not mean Spain’s airports will shut down. The Transport Ministry has already imposed minimum services for essential air transport, and agency reporting says those levels vary by airport and route type. During Semana Santa, some major airports are set to operate at well above half capacity for protected services, which means many flights should still run even if passengers experience slower processing on the ground.
Why passengers may still face delays even with minimum services
The broader concern is not only about cancellations, but about friction building through the day. Handling staff are responsible for baggage services, ramp operations and the movement of cargo and mail between the terminal and aircraft. If those services slow down, delays can spread from one flight to the next, especially at airports already working close to holiday capacity.
There is also a wider warning sign for Spain’s transport system here. Southern Spain has already been dealing with rail disruption affecting Málaga’s high-speed links, and an airport handling dispute adds to the sense of travel uncertainty just as the Easter movement gathers pace. For holidaymakers, second-home owners and residents flying out, the safest assumption is that airport journeys over the next several days may be less predictable than usual.

What travellers in Spain should expect next?
The immediate practical message is simple. Flights are likely to continue, but passengers should expect a greater risk of delays, longer waits and slower baggage handling from Monday onward if the dispute is not resolved. In a normal week, that would be inconvenient. In Semana Santa, it could become one of the biggest travel headaches of the holiday period.
