Hundreds of security workers responsible for passenger checks have commenced strike actions at Spain’s busiest airport, Adolfo Suárez Madrid-Barajas Airport (MAD), leading to major disruptions in airport operations and flight schedules.
The security personnel, who handle passenger checks such as filters, standard access and Fast Track lanes, walked off the job in the early hours of September 14, 2025, according to a statement issued by Madrid airport officials.
The strike includes around 800 personnel working for a private Spanish security company called Trablisa. Employees reportedly began strike action after failed negotiations with their employer over improved working conditions. Workers stated that their workload “far exceeds” that of other airports in Spain.
On September 15, 2025, airport operator Aena issued a statement saying that security clearance times at the airport “are being extended”.
“Aena is working with State Security Forces, airlines, and handling agents to minimize the impact as much as possible,” Aena said.
In certain areas, particularly terminal T4, travelers reported long lines and delays that exceeded the norm, reaching up to an hour and a half. In some cases, passengers missed their flights due to the delays in getting through security checkpoints.
Several passengers took to social media to complain, noting that huge queues had already formed at the airport from the early hours of the strike. Images shared on X show thousands of passengers at the airport, many waiting in large lines for their flights.

Madrid Airport fully operational despite strike
Madrid Airport officials said the Government Delegation in the Community of Madrid has ordered security services at the airport to function at full capacity, emphasizing the airport’s importance as “critical infrastructure”.
This means that, even during the strike, essential security functions must remain fully operational.
However, travelers who are going to Madrid or connecting through the airport are advised to check with their airline for any updates regarding possible delays.
According to airport officials, passengers departing from Madrid-Barajas should verify the opening times of check-in counters with their airline, as they usually open three to four hours prior to departure.
After obtaining a boarding pass, airport officials suggest that passengers head to security early and follow staff instructions to the correct control points near their gate.
Spain’s largest airline, Iberia, officially known as Iberia Líneas Aéreas, announced in a statement on X that airport access “is experiencing delays” due to the strike.
“We recommend arriving earlier than usual and taking advantage of our free carry-on check-in service to help you get through security faster,” the carrier said.
At the time of writing, no announcement has been made regarding an end date for the strike.
