The SAERCO air traffic controller strike enters its third consecutive day — and it shows no sign of ending.
No deal has been reached. No talks are scheduled. No suspension has been announced. The strike that began at midnight on Friday April 17 is as active on this Sunday morning as it was the moment it started — and for UK passengers at Lanzarote, Fuerteventura, Sevilla and Vigo today, that means a third day of delayed flights, reduced capacity, and zero cash compensation.
At the same time, Sunday carries its own particular urgency: thousands of Copa del Rey final fans are trying to fly home from Seville following last night’s Atlético Madrid vs Real Sociedad final at La Cartuja, while the first wave of Feria de Abril visitors is simultaneously arriving at Sevilla airport — the fair opens at midnight tomorrow. Sevilla’s ATC controllers, operating under a minimum services order at a SAERCO-managed tower, are handling a surge of football fans and flamenco-goers simultaneously. No other day of this strike has created quite this level of pressure at SVQ.
And then there is what happens tomorrow.
Published: April 19, 2026 — Sunday (Day 3) Strike status: 🔴 ACTIVE — Day 3 — indefinite, no end date, no deal Unions: USCA (Union of Air Traffic Controllers) + CCOO (Workers’ Commissions) Company: SAERCO — private air navigation services provider Airports affected: 14 — Lanzarote (ACE), Fuerteventura (FUE), La Palma (SPC), El Hierro (VDE), La Gomera (GMZ), Sevilla (SVQ), Jerez (XRY), Vigo (VGO), A Coruña (LCG), Castellón (CDT), Burgos (RGS), Huesca (HSK), Ciudad Real (CQM), Madrid-Cuatro Vientos (LECU) NOT affected today: Madrid-Barajas (MAD) · Barcelona El Prat (BCN) · Palma (PMI) · Málaga (AGP) · Tenerife Sur/Norte · Alicante · Valencia — all AENA-operated Dual-crisis airports: 🔴🔴 Lanzarote + Fuerteventura — SAERCO ATC strike active AND Groundforce mandate in force Sevilla extra pressure: Copa del Rey fan departures + Feria de Abril arrivals simultaneous today Next risk escalation: Monday April 20 — Groundforce resumes Mon/Wed/Fri pattern + Dubai 1-flight/day cap starts EU261 / UK261 cash: ❌ NO — ATC strike = extraordinary circumstances = zero cash entitlement Duty of care: ✅ YES — meals at 2hrs, hotel if overnight, fully applicable Refund / rebooking: ✅ YES — airlines must offer one or the other
When the SAERCO walkout began on Friday, some passengers hoped it might resolve quickly — that a few disrupted days might bring both sides to the table and a weekend deal might end the crisis. Three days on, that hope should be set aside.
The dispute centres on staffing shortages and working conditions, with unions accusing operator Saerco of pushing workers towards industrial action. According to USCA spokesperson Pablo Gomez Junquera: “Despite our efforts to reach an agreement — which I stress has nothing to do with economic issues — the company is pushing us to call a strike imminently.” The union claims the tower is operating with just 10 controllers, down from 16 when Saerco took over in 2021. At the same time, air traffic is expected to rise by nearly 10% as the busy summer season begins.
That statement was made before the strike even began. Nothing has changed since. The core demands — more staff hired, defined rest periods, fairer scheduling — are operational changes that take months to implement. SAERCO cannot resolve them with a weekend press conference. And the unions have made clear that their conditions are structural, not financial. This is not a dispute where management tables a higher number and everyone goes back to work.
Observers note that similar disputes in 2023 and 2024 were only resolved after several weeks of rolling cancellations.
The practical implication for Sunday: the strike is operating on identical terms to Friday and Saturday. Minimum services are in force. ATC capacity at all 14 airports is reduced. Flights are delayed — not cancelled wholesale, but delayed enough to cascade throughout the day. And with Monday now just hours away, the risk picture for the week ahead is more complex than anything this weekend has presented.
Of all the airports on the SAERCO list, Sevilla (SVQ) is carrying the most extraordinary additional load today.
Yesterday (Saturday April 18): The Copa del Rey final between Atlético Madrid and Real Sociedad was played at the Estadio de La Cartuja in Seville. Tens of thousands of fans from Madrid and San Sebastián flew into Sevilla for the match. They are now trying to fly home.
Today and tomorrow: The Feria de Sevilla 2026 begins on 20 April at midnight with the illumination. Visitors from across Spain and Europe are arriving in Sevilla today and tomorrow to be in position for the opening ceremony. The Feria runs until April 26 — seven days of Spain’s most iconic festival, drawing hundreds of thousands of visitors who need to fly in and fly out.
Sevilla’s ATC tower is operating with just 10 controllers, down from 16 when Saerco took over in 2021. Air traffic is expected to rise by nearly 10% as the busy summer season begins.
Under minimum services, those 10 controllers are managing a day where both outbound Copa del Rey traffic and inbound Feria traffic are simultaneously peaking — at an airport whose capacity was already stretched before the strike began. Every Ryanair, easyJet and Vueling flight departing Sevilla today is competing for a reduced number of departure slots. Every charter bringing Feria visitors in is competing for reduced arrival slots. The result is delays building from early morning, pushing through the midday peak, and extending into the evening.
If you have a Sevilla flight today — in either direction — add at minimum 2 hours to your airport arrival time. Do not cut it close. And if you are connecting onwards from another Spanish airport after landing at Sevilla, build a 4-hour minimum connection buffer.
Sunday disruption at SAERCO airports follows a predictable pattern that has now been confirmed across two days of live strike operation.
06:00–09:00 — Early morning wave UK overnight aircraft that repositioned at SAERCO airports are the first to be affected. The ATC tower opens for the day’s minimum service allocation. Slots are tighter than normal. Early departures — popular for Lanzarote and Fuerteventura where 07:00–09:00 flights are common — begin experiencing 20–40 minute delays as aircraft queue for departure clearance.
09:00–13:00 — Mid-morning cascade The first UK departures have arrived. Aircraft that should have landed at 09:30 land at 10:15. The turnaround window — typically 60–90 minutes — is compressed to 45 minutes. Boarding is rushed. Passengers who booked the 11:30 return flight to Manchester are now looking at a 12:30–13:00 actual departure.
13:00–18:00 — Afternoon peak pressure Multiple aircraft are simultaneously queuing for departure slots at Lanzarote, Fuerteventura and Sevilla. ATC under minimum services cannot clear the backlog at normal speed. Average delays on Friday and Saturday were 1–3 hours. This window is where the worst delays concentrated.
18:00–22:00 — Evening departures: highest individual delay risk Final wave of UK departures. Aircraft that were supposed to leave at 18:30 are now attempting to depart at 20:30 or later. Passengers on these flights should plan for a very late UK arrival. If you are using public transport from your UK airport — Luton, Stansted, East Midlands, Leeds Bradford — check the last train times now and plan alternative ground transport if your actual landing is after 22:00.
22:00–midnight — Late evening risk If an aircraft is significantly delayed and crew approach their maximum duty hours, the airline may cancel the final sector rather than risk a duty time violation. This is when cancellations — as opposed to delays — are most likely to occur. Check your airline’s app after 20:00 if you have a late evening departure.
For UK passengers, Lanzarote (ACE) and Fuerteventura (FUE) remain the airports of greatest concern. They are the two busiest UK routes of all 14 SAERCO airports by passenger volume, and they carry a second layer of risk that no other airport on the list shares.
The Groundforce baggage handling dispute — which covers 12 Spanish airports including both Lanzarote and Fuerteventura — remains fully in force. The mandate requires strikes every Monday, Wednesday and Friday in three time windows: 05:00–07:00, 11:00–17:00, and 22:00–midnight. Today is Sunday, which is not a scheduled Groundforce strike day. However, the mandate is unbroken and no deal has been confirmed.
This means:
Monday is therefore more dangerous than Sunday for Lanzarote and Fuerteventura passengers. See the full Monday warning below.
| Airport | Code | Sunday Risk | What’s Happening |
|---|---|---|---|
| Lanzarote | ACE | 🔴 HIGH | ATC minimum services Day 3; highest UK passenger volume; no Groundforce today but gap narrows towards Monday |
| Fuerteventura | FUE | 🔴 HIGH | Identical risk profile to Lanzarote |
| Sevilla | SVQ | 🔴 VERY HIGH | ATC minimum services + Copa del Rey departure surge + Feria de Abril arrivals beginning today |
| La Palma | SPC | 🟠 ELEVATED | ATC minimum services; easyJet + TUI from UK |
| Jerez | XRY | 🟠 ELEVATED | ATC minimum services; Ryanair from Stansted + Manchester; Feria de Abril visitors routing via Jerez |
| Vigo | VGO | 🟠 MODERATE | ATC minimum services; Ryanair from Stansted + Manchester |
| A Coruña | LCG | 🟡 MODERATE | ATC minimum services; limited direct UK |
| El Hierro + La Gomera | VDE/GMZ | 🟡 LOWER | Primarily inter-island; minimal direct UK |
Safe airports today (AENA-operated, NOT affected): Madrid-Barajas, Barcelona El Prat, Palma de Mallorca, Málaga, Tenerife Sur, Tenerife Norte, Alicante, Valencia, Gran Canaria, Bilbao, Ibiza.
Everything about Monday converges into the most complex aviation disruption day Spain has seen in years. Three independent crises activate simultaneously.
Crisis 1 — SAERCO ATC strike (Day 4) The indefinite walkout continues. No resolution is imminent. Monday’s minimum services order remains in place at all 14 airports. Every Lanzarote, Fuerteventura and Sevilla flight on Monday operates under the same reduced ATC capacity as today.
Crisis 2 — Groundforce Mon/Wed/Fri pattern resumes (if no deal) The indefinite Groundforce strike notice remains in force and could resume on Monday if talks collapse. As of Sunday April 19, no deal has been confirmed. The pattern requires strikes at 12 Spanish airports — including Lanzarote and Fuerteventura — in three windows: 05:00–07:00, 11:00–17:00, and 22:00–midnight. If Groundforce resumes Monday, passengers at Lanzarote and Fuerteventura face ATC capacity limits AND baggage service disruption at the same time, with no EU261 or UK261 cash compensation for either. This is the dual crisis that has been pending since April 17.
Crisis 3 — Dubai 1-flight-per-day cap starts From Monday April 20, all foreign airlines except Emirates and flydubai are restricted to a maximum of one daily rotation at Dubai International Airport. BA has cancelled its Dubai services to May 31. KLM to June 14. Lufthansa Group to May 31. Singapore Airlines to May 31. This reduces the pool of alternative routing options available to passengers trying to rebook off disrupted Spain flights — any passenger whose fallback was via a Dubai-connecting carrier now has fewer options.
What you should do today if you have a Monday Lanzarote, Fuerteventura or any SAERCO airport flight:
✅ Check your airline’s app for a Spain disruption waiver — Ryanair, easyJet, Jet2 and TUI typically issue free date-change waivers for confirmed strike periods. If a waiver is live and you have flexibility, moving to a Tuesday or Thursday avoids the Groundforce window risk (though the ATC strike remains indefinite).
✅ Confirm whether your airline uses Groundforce handling at your specific airport. If yes: prepare for the possibility of bag disruption on Monday in addition to any ATC delays.
✅ If you are a Jet2 Holidays or TUI package customer: call your tour operator today — Sunday — while customer service lines are open. Do not wait until Monday morning when every UK passenger with a Monday Spain flight will be doing the same thing.
This point has not changed since Day 1. An air traffic control strike is conducted by workers external to the airline. Under EU261, this is typically classified as an extraordinary circumstance — meaning the €250–€600 cash compensation usually does not apply. This is different from an airline’s own staff striking, where compensation does apply.
No matter how long your delay, how many times your flight is rescheduled, or how late you arrive home — if the cause is the SAERCO ATC strike, you cannot claim cash compensation from the airline. This is EU law and UK261 law. It applies to every UK, Irish and European passenger equally.
One exception that may apply: If your flight was delayed or cancelled during the SAERCO strike period but the actual reason was an airline-side issue — not ATC — you may still be entitled to compensation. Ask the airline for the specific reason for your disruption in writing. If they cannot demonstrate that ATC industrial action directly caused your flight’s cancellation, the extraordinary circumstances defence is weaker.
Always ask your airline: “Please confirm in writing the specific operational reason for this delay/cancellation.” If they say “ATC strike,” you accept that. If they say “crew shortage,” “technical fault,” or “late inbound aircraft from a non-SAERCO airport” — you may have a compensation claim.
If your flight is cancelled, you are entitled to a full cash refund to your original payment method within 7 days. This right cannot be removed by extraordinary circumstances. Airlines cannot insist on giving you a voucher. If offered a voucher, state clearly: “I am invoking my right to a full cash refund under EU Regulation 261/2004 Article 8.” Document the response.
If your flight is cancelled and you still want to travel, the airline must rebook you to your final destination at the earliest opportunity. During an indefinite ATC strike, “earliest opportunity” may be several days. You are not obliged to accept a rebooking that is 5 days away if the airline can find you a faster alternative routing — via an AENA-operated Spanish airport, or via a different connecting hub.
Extraordinary circumstances removes cash compensation, but it does NOT remove duty of care. Airlines must still provide:
2+ hour delay → meals and refreshments. You do not need to wait to be offered. Go to the check-in or gate desk and say: “My flight has been delayed over two hours. Under Article 9 of EU Regulation 261/2004, I am requesting meal vouchers.” Keep every receipt regardless of whether vouchers are provided — you can submit receipts for reimbursement if the airline failed to provide care.
Overnight cancellation → hotel accommodation + transfer. If your flight is cancelled and no same-day alternative is available, the airline must arrange and pay for your overnight hotel and transport to and from it. Ask at the airline desk. If no representative is available at the airport, call the airline’s emergency line. Do not book a hotel yourself without first asking the airline to arrange it — if you do book independently, keep every receipt and submit with a written explanation of why airline-arranged accommodation was not available.
Two free communications. You are entitled to make two free phone calls, send two emails, or send two faxes to notify people of your disruption. Ask the airline desk or ground handling staff.
If you booked through Jet2 Holidays, TUI, Thomas Cook, On the Beach, Love Holidays or any ATOL-protected package operator, your rights are materially stronger than independent travellers.
Under the UK Package Travel and Linked Travel Arrangements Regulations 2018, if your package is “significantly affected” by the strike, your tour operator must:
“Significantly affected” typically means a cancellation, a forced change of travel date of more than 12 hours, or a situation where you cannot reach your destination within a reasonable time.
The crucial difference: Tour operators cannot hide behind extraordinary circumstances the way airlines can. Their obligation to you under the Package Travel Regulations does not have an ATC strike exemption. If the flight cannot operate and no comparable alternative is offered, you get your money back.
Call your tour operator — not the airline — as your first point of contact. The number to call is the operator’s customer service line, not the check-in desk at the airport.
Check each airline’s website or app for an active Spain ATC disruption travel advisory. These are typically updated daily during active strike periods.

Each day of this strike carries the same structural disruption, but Sunday has its own distinct character for UK passengers:
Sunday is the return day for week-long package holidays. Thousands of Jet2 and TUI customers who flew out the previous Sunday are today flying home. These are passengers who have been away for 7 days — they cannot extend their holiday, their accommodation has checked them out, and they need to be back in the UK tonight for work tomorrow. For this group, a flight delay of 3+ hours is not an inconvenience — it is a genuine hardship. The duty of care obligation for delays and overnight stays matters most to these passengers.
Sunday afternoon is when delays compound most severely. Saturday changeover day already delayed many aircraft. Those delays push into Sunday’s early morning slots. An aircraft that landed at Lanzarote 2 hours late on Saturday afternoon may still be running 90 minutes behind on Sunday morning, because the engineering, cleaning and positioning rotations are all subsequently late. By Sunday afternoon, the cumulative backlog from Friday, Saturday and Sunday can produce the longest delays of the entire weekend.
Monday is 24 hours away — and the risk increases. Unlike Saturday passengers who had the option to rebook to Sunday, Sunday passengers have fewer options. Moving your Sunday flight to Monday means accepting a Groundforce-risk day AND a SAERCO-risk day simultaneously at Lanzarote and Fuerteventura.
The SAERCO strike is now confirmed to be running into its third week of the broader Spain aviation disruption story (Groundforce began March 30, SAERCO Day 3 today). For UK passengers with summer 2026 Spain bookings, the questions are no longer about this weekend — they are about the next several months.
The Canary Islands are more exposed to aviation disruption than most mainland destinations because there is no realistic alternative to flying for the vast majority of international visitors.
The structural nature of the SAERCO dispute means Lanzarote, Fuerteventura, La Palma, Sevilla and Vigo carry ATC strike risk for as long as SAERCO and the unions fail to agree staffing levels and collective working terms. That is not a financial negotiation that can conclude over a weekend — it requires SAERCO to hire additional controllers (which takes months), implement new scheduling systems, and negotiate a full collective agreement.
Meanwhile the Feria de Abril runs April 20–26 — every day of the Feria is a day when Sevilla airport faces elevated passenger demand on top of minimum-service ATC operations.
The practical advice for UK passengers with upcoming Spain bookings:
| Day | Date | SAERCO Status | Groundforce | Additional |
|---|---|---|---|---|
| Day 1 | Fri 17 Apr | 🔴 Active from midnight | Suspended (Fri not a strike day) | Europa Triple Strike with Lufthansa + Stansted |
| Day 2 | Sat 18 Apr | 🔴 Active — peak UK changeover day | Not active (Sat) | Copa del Rey final at Sevilla |
| Day 3 (today) | Sun 19 Apr | 🔴 Active — return-day pressure | Not active (Sun) | Copa del Rey fans departing + Feria arrivals |
| Day 4 (tomorrow) | Mon 20 Apr | 🔴 Active (indefinite) | 🔴 Resumes unless deal | Dubai 1-flight/day cap starts |
| Day 5 | Tue 21 Apr | 🔴 Active (indefinite) | Not a Mon/Wed/Fri day | Feria de Abril in full swing |
| Day 6 | Wed 22 Apr | 🔴 Active (indefinite) | 🔴 Active if no deal | Feria + dual disruption at ACE + FUE |
