An indefinite strike by Trablisa security personnel on Sunday caused major disruptions at Adolfo Suárez Madrid-Barajas Airport, with passengers facing wait times of up to 95 minutes at security checkpoints and multiple flight delays.
The strike affected all terminals and was declared after negotiations over pay and working conditions broke down.
Airport operator Aena confirmed that the strike led to crowding and extended queues at passenger access points, despite a 100% minimum service order. Authorities said that wait times began returning to near normal by early afternoon, but the disruption highlighted vulnerabilities in airport operations and subcontracted security processes.
Security staff managed by Trablisa walked off the job early Sunday, citing excessive workloads and demanding better pay, hazard bonuses, and recognition of Barajas’ high passenger volumes. The strike committee claims Barajas handles far more passengers than other Spanish airports and therefore warrants higher compensation. Alejandro Corredera Arriaga, a Trablisa spokesperson, said the lack of extra pay was “unjustifiable.”
Aena confirmed that wait times at Terminal 4 dropped to around 7 minutes by midday, while other terminals saw times as low as 14 minutes, and stated that flight operations were not uniformly affected. However, the Association of Airlines (ALA) described the disruption as causing “serious harm” to passengers and called for a swift resolution. Javier Gándara, president of ALA, urged the airport operator to “take the necessary measures to end the chaos.”
Legal Dispute and Operational Response
Trablisa has requested that the Madrid Regional Institute of Mediation and Arbitration declare the strike “illegal and abusive,” arguing that only 21 of the more than 850 security staff are participating and that the strike violates existing labor agreements. The company said that pay increases—totaling 16% through 2026—had already been implemented and characterized the strike as “disproportionate.”
Despite the strike, Aena deployed staff at subway and terminal entrances and emphasized it had ordered a 100% minimum service level. Aena said it regrets the disruptions and continues to monitor operations, but acknowledged that the extended wait times early Sunday were unavoidable. The company also noted that delays were more severe earlier in the morning and that conditions improved later in the day.
Context and Broader Travel Disruptions
The Barajas strike forms part of a wider wave of labor unrest impacting Spanish airports this year, which has included baggage handler walkouts and passport control delays. Similar incidents at Madrid’s Terminal 4 earlier this summer raised questions about capacity and staffing at Spain’s busiest international hub. Reports already suggest that flight cancellations and passenger backlogs from this strike could ripple into other busy travel periods.
Travelers were advised to arrive at least three hours early and consider checking carry-on luggage to reduce processing times. Many passengers at Madrid and other airports have turned to high-speed train services or alternate departure airports to mitigate the risk of missed flights. Airlines have offered rebooking and refund options for affected passengers, though compensation under EU Regulation 261 is generally not available when disruptions stem from subcontractor strikes.
As of late Sunday, it remained unclear when the strike would end. Trablisa’s move to challenge the strike legally and the Madrid government’s insistence on full staffing suggest further disruption is possible during negotiations. Passengers traveling through Madrid-Barajas this week may face ongoing delays unless a settlement is reached promptly.
