Upcoming Spanish Aviation Crisis: What You Need to Know

Four days from now, a second Spanish aviation crisis begins — and this one is more dangerous for passengers than the Groundforce dispute that paralyzed Easter.

Starting at midnight on Friday, April 17, air traffic controllers in SAERCO-managed towers across Spain will commence an indefinite strike. This action raises the risk of significant disruption at 14 airports nationwide. The strike, called by the Union of Air Traffic Controllers (USCA) and Workers’ Commissions (CCOO), is rooted in long-standing administrative issues, including staff shortages, work overload, and irregular schedules.

Key Details of the Strike

• Published: April 13, 2026
• Strike Start: Midnight Friday, April 17, 2026 (00:00 CET)
• Duration: Indefinite — no end date
• Unions Involved: USCA (Union of Air Traffic Controllers) + CCOO (Workers’ Commissions)
• Target Company: SAERCO (private air navigation service provider)
• Airports Affected: 14 (full list below)
• Root Cause: Staff shortages, work overload, irregular schedules, failed collective agreement negotiations
• Airlines’ Obligations: Rebooking or refund — but NO fixed cash compensation
• Minimum Services: Will be ordered by Spain’s government — extent TBC
• Mediation Status: USCA/CCOO requested mediation via SIMA before filing — meetings with SAERCO were repeatedly postponed or canceled, triggering the strike notice
• Existing Groundforce Status: Suspended for talks since April 8 — but resumption expected Monday, April 13, if no deal is confirmed
• Critical Warning for Lanzarote + Fuerteventura: Both airports face dual strike risk — SAERCO ATC from April 17 AND potential Groundforce resumption

Why This Strike Is More Dangerous Than Groundforce

The Groundforce strike, which affected 12 Spanish airports with baggage handler walkouts, was disruptive but did not halt flights. Passengers still arrived at their destinations, often on time or close to it. In contrast, the SAERCO ATC strike is fundamentally different:

1. Flights Cannot Depart: Without a controller clearing your aircraft for pushback, taxi, and takeoff, the aircraft remains stationary. This is not a slower process; it is a completely halted process.

2. Flights Cannot Land: Aircraft approaching an airport managed by a striking tower may be held in holding patterns or diverted to alternative airports entirely.

3. Every Airline is Equally Affected: Unlike the Groundforce dispute, which was company-specific, the SAERCO dispute impacts every airline flying to or from the 14 affected airports simultaneously. There is no workaround for airlines during an ATC strike.

4. Indefinite Duration: An ATC strike with no end date means no reliable rebooking window. If you rebook from April 17 to April 18, the strike may still be ongoing. The dispute will continue until SAERCO agrees to a collective agreement with USCA and CCOO.

The Full List of 14 Affected Airports

The strike will impact the following airports in Spain:

• Madrid-Cuatro Vientos
• Lanzarote
• Fuerteventura
• La Palma
• El Hierro
• La Gomera
• Castellón
• Burgos
• Huesca
• Ciudad Real
• Vigo
• A Coruña
• Jerez
• Seville

Significance for UK Travellers:

• Lanzarote (ACE): One of the UK’s busiest Canary Islands routes.
• Fuerteventura (FUE): Major UK beach holiday destination.
• La Palma (SPC): Popular Canary Islands destination.
• Sevilla (SVQ): Major UK city break destination.

The Lanzarote and Fuerteventura Double Strike Threat

Passengers flying into and out of Lanzarote and Fuerteventura may face compounded issues as both ground handling staff and air traffic controllers will be staging walkouts. This combination poses the highest risk:

• Air Traffic Control Restrictions: Limiting how many aircraft can operate per hour.
• Baggage Handlers Reduced or Absent: During Groundforce strike windows.
• All Airlines Simultaneously Affected: No workaround available.
• No EU261 Cash Compensation: Both ATC and ground handling strikes are classified as extraordinary circumstances.

What SAERCO Is and Why This Happened

SAERCO (Sociedad Anónima Española de Control y Organización) is a private company providing air navigation services at several Spanish airports, primarily regional and island airports. The unions argue that the dispute stems from long-standing structural issues, including staff shortages and irregular scheduling practices.

Workers are demanding sufficient staffing levels, respect for rest periods, and working conditions compatible with safety and professionalism. The unions emphasize that their demands are not economic but rather focused on operational safety.

Minimum Services — What This Means in Practice

Under Spanish law, essential public services, including air traffic control, must maintain minimum service levels during strikes. The Ministry of Transport will issue a minimum services order specifying what percentage of operations must continue. However, there are two important caveats:

1. Minimum Services Do Not Protect Your Specific Flight: The order might guarantee a percentage of flights, but it does not specify which flights will operate.

2. Controllers Believe Current Minimum Services Are Too High: This grievance has led to increased striking and delays.

EU261 and UK261 Rights — The Critical No-Compensation Rule

ATC strikes are classified as extraordinary circumstances, meaning passengers are not entitled to fixed cash compensation. Under EU Regulation 261/2004 (and its UK equivalent), airlines must pay fixed compensation when a flight is delayed or canceled due to their fault. However, ATC strikes by third parties are consistently classified as extraordinary circumstances.

What You Are Entitled To:

• Rebooking onto the Next Available Flight
• Full Refund if You Choose Not to Travel
• Right to Care During the Wait
• Right to Information

What You Are Not Entitled To:

• Fixed cash compensation
• The right to demand rebooking onto a competitor’s aircraft
• Compensation for consequential losses

UK Airlines Operating at the Affected Airports

Lanzarote (ACE): Ryanair, easyJet, Jet2, TUI
Fuerteventura (FUE): Ryanair, easyJet, Jet2, TUI
La Palma (SPC): easyJet, TUI, Jet2
Sevilla (SVQ): Ryanair, easyJet, Vueling, Iberia Express
Vigo (VGO): Ryanair
A Coruña (LCG): Ryanair

Action for Each Airline:

• Ryanair: Check for Spain travel advisory and “No Show” policy.
• easyJet: Look for travel waivers.
• Jet2: Generally proactive in customer communication.
• TUI: Broader duty-of-care obligations as a package holiday provider.

Package Holiday Passengers — Your Rights Are Stronger

If you booked a package holiday through an ATOL-protected tour operator, your rights are significantly stronger than those of independent flight bookers. Under UK regulations, your tour operator has legal responsibility for your complete holiday, meaning:

• If your flight is canceled, the tour operator must offer an alternative package or a full refund.
• The tour operator cannot simply cancel your flight and leave you to sort out your hotel independently.

What to Do RIGHT NOW — Your 4-Day Action Plan

TODAY (Sunday, April 13):

• Check if Your Flight is Affected: Use the airport list.
• Review Your Travel Insurance Policy: Ensure it covers strikes.
• Look Up Airline Travel Waivers: Check for flexibility in travel dates.
• Contact Your Tour Operator: Understand their disruption policies.

April 14-16 (Monday–Wednesday):

• Monitor Airline Notifications: Be proactive about cancellations.
• Check Mediation Outcomes: Stay updated on negotiations.
• Pack Essentials in Cabin Baggage: Especially if flying to Lanzarote or Fuerteventura.

April 17 and Beyond:

• Check Flight Status Early: Don’t arrive at the airport for a canceled flight.
• Allow Extra Time at the Airport: Expect congestion.
• Know Your Rights: Ask for meal vouchers and rebooking options if delayed or canceled.

The Groundforce–SAERCO Double Context

Spain has been experiencing a sustained aviation labor crisis since late March 2026. The Groundforce baggage handlers’ dispute has now escalated with the SAERCO air traffic controllers’ strike. If both strikes coincide, Spain will face a complex aviation labor crisis, severely impacting passengers.
