(MADRID, SPAIN) Spain’s busiest airport, Adolfo Suárez Madrid–Barajas, is facing major disruptions after an indefinite security strike by Trablisa employees entered its third day, leaving passengers in long lines and some missing flights as airlines scramble to adjust schedules and rebooking rules.
The security strike began on September 14, 2025, and has produced security queues stretching up to 90 minutes, especially around Terminal 4. While social media posts suggest large numbers of missed departures, there is no official confirmation that 1,900 passengers failed to board; however, the scope of delays makes that figure plausible given current conditions.
About 800 Trablisa security staff are involved in the action, which unions say stems from pay shortfalls and workloads “far beyond” those seen at other Spanish airports this year. The employer disputes the scale of participation and has asked the Madrid Regional Institute of Mediation and Arbitration to declare the action “illegal and abusive.” For travelers, the debate has one clear outcome: a slower, more stressful path to the checkpoint at a hub they rely on for business, family visits, and connections across Europe and Latin America.
Operational impact and official response
Aena, the airport operator, says security clearance times are running longer and that staff are working with airlines and authorities to reduce bottlenecks where possible. The Government Delegation in the Community of Madrid has ordered that security services remain fully operational because Madrid–Barajas is considered critical infrastructure.
In practice, reduced staffing means some posts are open but thinly manned during peak times, creating stop-and-go surges that ripple across check-in, security, and boarding. Peaks around early morning waves and late evening returns trigger the longest lines, while mid-day windows can be calmer. Families with strollers and those with reduced mobility face longer waits because dedicated lanes are stretched thin.
Airlines, led by Madrid-based Iberia, are urging passengers to:
– Arrive far earlier than usual
– Complete online check-in in advance
– Consider checking hand luggage to shorten waits at screening
Iberia has offered flexible rebooking for flights set to depart September 14–15, with changes allowed through September 20, 2025, for tickets bought on its direct channels. Other carriers are issuing similar guidance and pushing alerts through apps and email.
Causes of the dispute
Unions say the dispute is rooted in:
– Low wages
– Staff shortages
– Lack of stable collective agreements
Worker groups argue the post-pandemic rebound in travel has not translated into fair pay or staffing levels at Spain’s largest hub. Trablisa counters that only a small share of personnel have walked out and says the action is disproportionate to the issues raised. Passengers stuck in long lines are caught between these claims, with many posting videos showing dense crowds in Terminal 4 and reports of missed flights after reaching the gate too late.
Wider context: labour action across Spain in 2025
The standoff in Madrid is part of a larger wave of labor action across Spanish airports in 2025, including recent walkouts in:
– Barcelona
– Seville
– Alicante
– Ibiza
– Malaga
– Palma de Mallorca
– Tenerife South
– Girona
– Lanzarote
– Santiago de Compostela
Earlier actions rolled out in time bands across the day and, if demands were not met, continued every Wednesday, Friday, Saturday, and Sunday through the peak season. In that context, the indefinite Madrid action looks like a further escalation at a hub that handles huge volumes of domestic and international traffic.
Connections, knock-on effects and practical consequences
Minimum connection times at Madrid are typically 20 minutes for domestic and 60 minutes for international itineraries. Those figures quickly become unrealistic during a security strike.
Missed connections create a cascade:
1. Passengers rebook onto later flights, tightening seat availability.
2. Strains spread to baggage handling, customer service desks, and overnight accommodation.
3. Aircraft can depart with empty seats that should have been filled, straining airline finances and reshuffling crew duty times.
For travelers with visa appointments, study programs, or work assignments, the human impact is significant. A missed departure can mean:
– Losing a biometrics slot
– Arriving after a residency deadline
– Missing a day of paid training
– Losing nonrefundable family reunion bookings
Analysis by VisaVerge.com highlights how private security contracts affect the wider mobility chain, especially when strikes target screening rather than airline operations—placing the pressure point before passengers even reach their gate.
Government stance and legal framing
The political response aims to keep the airport running while avoiding a full-scale shutdown. By classifying Madrid–Barajas as critical infrastructure, the government signals that essential services must continue, even during a dispute. That order does not end the strike or force a settlement, but it tries to guarantee a floor of service. In practice, that floor is uneven.
This is not an airline strike, which matters for rights and compensation. Under EU rules, when delays and cancellations stem from airport security staff, carriers often treat them as outside their control. Even so, passengers may still have rights to care, like meals and accommodation, depending on the length of delay and the final outcome of the journey.

Passenger rights, travel insurance and documentation
Travel insurance can help bridge gaps where compensation is limited. Policies differ, so travelers should:
– Review strike coverage, documentation requirements, and claim deadlines
– Keep boarding passes, delay notices, and receipts for food and lodging
– Save communications (emails, screenshots) from airlines and the airport
For students, workers on assignment, and families on tight schedules, those records also support requests for help from schools, employers, or consulates if arrival delays cause missed check-ins or legal appointments.
If you’re rebooked onto a later flight, ask the carrier to confirm the reason in writing. If a missed flight forces an overnight stay and you risk overstaying a Schengen allowance or arriving after a fixed visa activation window, present proof of the security strike disruption to border or consular officials.
Keep proof of disruption: boarding passes, airline rebooking confirmations, screenshots of alerts and official notices can be crucial if you need to explain missed appointments or visa timelines.
Practical steps for travellers (quick checklist)
- Arrive early: Plan to reach the airport at least 3–4 hours before departure while the strike continues.
- Check in online: Download boarding passes and verify your terminal.
- Minimize hand luggage: If offered, use free carry-on check-in to speed screening.
- Monitor updates: Watch airline apps and airport alerts for gate or time changes.
- Rebooking options: Contact your airline promptly if you risk missing a flight.
- Document everything: Save receipts and communications for claims.
- Know EU rights: Review official guidance on delays, cancellations, and care.
Additional tips:
– Families with young children: pre-arrange assistance where eligible.
– Travelling with medication or time-sensitive documents: keep them in an easy-access pouch and carry copies.
– Elderly or reduced mobility passengers: request assistance early — priority lanes are stretched.
Outlook and what to expect next
The near-term outlook depends on talks between Trablisa and the unions. Possible scenarios:
– If a deal is reached: relief could come quickly as rosters return to normal and queues ease.
– If no deal: the strike may spread or inspire fresh actions at other airports, forcing airlines to keep adjusting day by day and prioritizing long-haul and high-demand routes.
Travelers connecting through Madrid should assume that legal connection times are not enough during the strike and should request later onward flights where possible. Those with tight immigration timelines should alert hosts and employers and carry proof of the disruption.
As of September 16, 2025, there is no announced resolution. Aena and airlines continue to coordinate, and the government’s minimum service order remains in place. Lines can lengthen without warning when a surge hits security, so even travelers with priority access should allow extra time.
The heart of the dispute—pay, staffing, and conditions—will be solved in negotiations that recognize the vital role of security staff. Until then, patience, preparation, and thorough documentation are the best tools passengers have.
This Article in a Nutshell
A Trablisa-managed security strike at Adolfo Suárez Madrid–Barajas began on September 14, 2025, and entered a third day with security lines up to 90 minutes, notably in Terminal 4. Unions blame low wages, staffing shortages and the absence of stable collective agreements; Trablisa disputes the strike’s scale and has asked for it to be declared illegal. Aena and the regional government require minimum services, but reduced staffing creates stop‑and‑go surges affecting check‑in, security, and boarding. Airlines, led by Iberia, advise early arrival, online check‑in and checked luggage; Iberia offers flexible rebooking for flights on September 14–15 with changes allowed through September 20. The dispute is part of a wider pattern of labor action across Spanish airports in 2025. Passengers should document disruptions, review travel insurance and EU passenger rights, and allow extra time for connections and screening while negotiations continue without a resolution as of September 16, 2025.
