Forty days. The SAERCO air traffic control strike — the longest continuous aviation industrial dispute in Spain since the 2010 crisis — has reached Day 40 this morning with no deal, no talks, and no end date in sight. And today of all days — the Monday that opens UK half term week — adds two further simultaneous disruption layers that make May 26 the highest-risk day for British Spain-bound travellers since the strike began on April 17. Unions CCOO, UGT and USO launched an indefinite Groundforce strike with three daily stoppage windows — affecting baggage and ramp services at 12 major Spanish airports including Madrid, Barcelona, Alicante, and Málaga — and today is Monday, one of the three scheduled Groundforce strike days. Meanwhile, UK May half term 2026 runs from Monday May 25 to Friday May 29 — most schools return Tuesday June 2 — with Monday May 25 being the Spring Bank Holiday, meaning the family travel surge began yesterday and reaches its departure peak today. Forty days of SAERCO minimum-service ATC. A Monday Groundforce window. Half a million UK families flying to Spain this week. Around 20,000 flight movements and 2.6 million passengers faced disruption in the first month of the strike alone — and month two has just begun. Here is everything you need to know before you fly.

The SAERCO strike is now the longest continuously active aviation industrial dispute in Spain since the infamous ATCO wildcat strike of December 2010, which triggered a national emergency and a military takeover of air traffic control. That context matters: the Spanish government has not intervened in the same way this time, because SAERCO — unlike 2010’s AENA controllers — is a private company whose workers are not classified as civil servants.
The action was jointly called by USCA and CCOO after a final mediation session at SIMA on 10 April 2026 failed to produce a deal. The unions say the dispute centres on staffing shortages at SAERCO towers pushing workloads beyond safe limits, compulsory on-call shifts and last-minute roster changes breaching their collective agreement, and concerns about operational fatigue and aviation safety. Fox News
The strike is indefinite and will continue until SAERCO and the unions reach a new agreement. As of late April, no fresh talks have been scheduled. Travel And Tour World
This is the critical point for UK half-term families: there is no mechanism forcing SAERCO to settle. AENA — the state-owned airport authority — could ultimately replace SAERCO at these towers with in-house ENAIRE controllers, but that process requires regulatory changes and takes months. The government minimum services order keeps flights running at 34% capacity, protecting SAERCO’s revenue position and removing some of the commercial pressure that would normally force a settlement. The strike’s financial impact falls almost entirely on the airlines and passengers — not on SAERCO.
This dispute is structurally at a standstill. Unless SAERCO improves its offer substantially, the USCA and CCOO have no incentive to return to talks. Unless the government intervenes with compulsory arbitration or threatens SAERCO’s operating licence — neither of which has been publicly considered — Day 40 looks exactly like Day 1.
Not every day of UK half term carries the same risk. Here is the week-by-week risk map:
| Date | Day | SAERCO ATC | Groundforce | UK Peak? | Risk Level |
|---|---|---|---|---|---|
| May 26 (TODAY) | Monday | 🔴 Day 40 | 🔴 ACTIVE — 3 windows | 🔥 PEAK DEPARTURE | 🔴🔴 MAXIMUM |
| May 27 (Tomorrow) | Tuesday | 🔴 Day 41 | ✅ No action | SCQ REOPENS | 🟠 Elevated |
| May 28 | Wednesday | 🔴 Day 42 | 🔴 ACTIVE — 3 windows | Mid-week travel | 🔴 HIGH |
| May 29 | Thursday | 🔴 Day 43 | ✅ No action | No peak | 🟠 Elevated |
| May 30 | Friday | 🔴 Day 44 | 🔴 ACTIVE — 3 windows | Return departures | 🔴 HIGH |
| May 31 | Saturday | 🔴 Day 45 | ✅ No action | Peak returns | 🟠 Elevated |
| June 1 | Sunday | 🔴 Day 46 | ✅ No action | Peak returns | 🟠 Elevated |
| June 2 (Schools back) | Monday | 🔴 Day 47 | 🔴 ACTIVE | Return crush | 🔴 HIGH |
Today — Monday May 26 — combines the peak outbound family departure day with a Groundforce strike day. The majority of UK families who took the full 9-day break opportunity (Saturday May 23 through Sunday May 31) will depart for Spain today. Airlines know this. They scheduled extra capacity for today. That extra capacity arrives at Spanish airports during Groundforce’s 11:00–17:00 window — the prime afternoon peak.
Groundforce baggage handlers have been striking every Monday, Wednesday, and Friday since March 30 at 12 Spanish airports — including Madrid-Barajas, Barcelona-El Prat, and Malaga-Costa del Sol. The dispute over pay and weekend overtime rates affects roughly 3,000 workers. Travel And Tour World
Today’s three active windows:
🔴 05:00–07:00 — Morning bank disruption. UK charter and scheduled departures leave for Spain between 06:00 and 09:00. At Spanish destination airports receiving early UK arrivals — Lanzarote, Fuerteventura, Palma, Málaga, Alicante — the turnaround ground crews that need to process arriving aircraft for the first outbound services are disrupted during this window. Aircraft arriving from the UK at 08:00 find their ground handling delayed. The outbound service that should depart at 09:30 departs at 10:45.
🔴 11:00–17:00 — Peak departure window. This is the most damaging window for half-term outbound UK flights. The bulk of UK departures to Spain happen between noon and 5pm — Ryanair from Stansted to Lanzarote at 14:30, easyJet from Gatwick to Málaga at 13:15, Jet2 from Manchester to Palma at 12:45. Every one of these departures is operating while Groundforce’s strike windows are fully active at the destination airport. Baggage loading is slower. Ramp services are compressed. Aircraft push-back is delayed. Flights that were on time depart 30–60 minutes late.
🔴 22:00–00:00 — Late-night return window. Families returning to the UK on evening flights (21:00–23:00 departures from Málaga, Palma, Alicante, Barcelona) find their aircraft undergoing ground handling during the final strike window. A 22:15 departure from Málaga to Gatwick runs into baggage loading delays. It departs at 23:20. It lands at Gatwick at 01:10. By the time families with young children collect their bags and reach their cars, it is 02:00.
SAERCO ATC (Day 40) + Groundforce Monday windows SIMULTANEOUSLY
Lanzarote and Fuerteventura are today’s most dangerous airports for UK half-term families. Minimum services at SAERCO airports are approximately 34% on lower-traffic routes up to full coverage for emergency, medical and Canary Islands inter-island lifeline flights. Fox News
In practice, 34% capacity at Lanzarote and Fuerteventura means this: the SAERCO tower has enough controllers to handle roughly one-third of normal traffic. Airlines submit their schedules and the FAA-equivalent Spanish authority decides which flights get a slot. The ones that get a slot operate — often late. The ones that don’t get a slot are cancelled.
For half-term families flying to the Canary Islands today: check your flight status RIGHT NOW before leaving for the airport. If your airline’s app shows your Lanzarote or Fuerteventura departure as confirmed — check FlightAware for the inbound aircraft. If the aircraft is late or hasn’t left the UK yet — your departure is delayed regardless of what your confirmation email says.

Post-Feria recovery — now entering half-term June surge window
Seville is the third most SAERCO-impacted airport in Spain after the Canary Islands pair. The Feria de Abril added weeks of outbound pressure to SVQ — that’s now over — but Sevilla is entering half-term season with its most popular festival period behind it and the summer sun season beginning. UK families choosing Seville for a half-term city break face today’s dual disruption.
Seville is also a Groundforce airport today — baggage handling is under the 11:00–17:00 window for the afternoon peak. Ryanair’s Stansted–Seville service and British Airways’ Heathrow–Seville connection are both operating under this combined pressure.

Santiago de Compostela closes TOMORROW — Vigo and A Coruña taking all northwest Spain traffic
Santiago de Compostela Airport closed April 23 for runway renovation — it reopens tomorrow May 27. Today is the last full day of the SCQ closure. For the past 33 days, every passenger trying to reach northwest Spain has been using Vigo and A Coruña — both SAERCO airports — as their only alternatives. That elevated traffic load has added constant pressure to two airports that were already operating at SAERCO minimum service levels. Travel Tourister
From tomorrow (May 27): Santiago reopens. Ryanair and British Airways SCQ services should resume — check your airline for confirmation and updated gate information. The first week back at SCQ after a 33-day closure will be operationally impacted: ground staff repositioning, SAERCO controllers handling a renewed traffic load, and weeks of pent-up demand all arriving simultaneously.
AENA-operated — NOT affected by SAERCO ATC — but Groundforce Monday active at both
This is the most important clarification in this entire article for UK half-term families: Madrid and Barcelona are NOT SAERCO airports. Major hubs like Madrid-Barajas and Barcelona-El Prat are controlled by state-owned ENAIRE and continue operating normally, though knock-on delays are common. Travel And Tour World
However — both Madrid and Barcelona ARE Groundforce airports today. Baggage handling, ramp services, and ground operations at MAD and BCN are operating under Groundforce’s Monday windows: 05:00–07:00, 11:00–17:00, and 22:00–00:00.
For families flying to Madrid or Barcelona for half term: ATC is completely normal. Your flight will have a normal slot. It will be handled by AENA’s ENAIRE controllers with no capacity restriction. Your risk today is only Groundforce — delayed baggage loading, possible 20–45 minute departure delays. Much less severe than Lanzarote, but not zero.
AENA-operated — NOT affected by SAERCO — but Groundforce Monday active
Palma, Málaga, Alicante, and Tenerife are the four most popular half-term destinations for UK families — and ALL FOUR are Groundforce airports without SAERCO ATC risk.
For the millions of UK families flying to these airports this week: your primary risk is Groundforce’s Monday baggage windows — not ATC. Your flight will get a slot. Your ATC handling is normal. Your bags might be 30–60 minutes slower. This is manageable, especially if you travel carry-on only.
The practical advice for Palma, Málaga, Alicante, and Tenerife today: ✅ Travel carry-on only if your trip allows it — eliminates Groundforce baggage risk entirely ✅ If you must check bags — arrive at your departure airport 3 hours before departure ✅ Track your bags via your airline’s baggage tracking app (Ryanair, easyJet, and Jet2 all have this)
Lanzarote + Fuerteventura + Seville + Vigo + A Coruña + Barcelona + Madrid + Palma + Málaga + Alicante
Ryanair has more Spain routes from the UK than any other carrier. Today — Monday May 26, half-term peak, Groundforce day, SAERCO Day 40 — Ryanair is simultaneously exposed at every category of Spanish airport: SAERCO-only, Groundforce-only, and dual-crisis.
The Ryanair no-interline warning: Ryanair has zero interline agreements. A cancelled Ryanair Spain flight cannot be transferred onto easyJet, Jet2, TUI, or any other carrier. Your options: rebook within Ryanair’s own network or take a full cash refund. There is no automatic transfer to an alternative Spain service.

Gatwick, Luton, Bristol, Manchester, Edinburgh → Palma, Málaga, Alicante, Barcelona, Lanzarote
easyJet is the second most exposed UK carrier at Spain today. Its primary half-term Spain network concentrates on Palma, Málaga, Alicante, and Barcelona — all Groundforce airports without SAERCO ATC risk. easyJet’s Lanzarote and Fuerteventura services are exposed to the full dual crisis.

Jet2 operates the dominant Spain charter programme from Northern England airports — and its half-term Spain departures are today’s highest-emotion flights. Families who have waited months for this holiday, who booked 10+ months ago, who are packing tonight for tomorrow’s departure — these are Jet2’s half-term customers.
Jet2 has a strong duty-of-care track record. If your Jet2 Spain flight is significantly delayed today, the Jet2 rep at the departure airport will proactively offer vouchers and updates. Ask explicitly for meal vouchers the moment the delay exceeds 2 hours — Jet2 staff will provide them without needing a formal UK261 request.
Contact Jet2: jet2.com | 0333 300 0042 (UK)
Package holiday customers have ADDITIONAL protections — read this section carefully
TUI operates comprehensive package holidays to Spain — including Lanzarote, Fuerteventura, Palma, Tenerife, and mainland Spain. If you booked a TUI holiday package (flight + hotel), your protections go significantly beyond UK261:
Package Travel Regulations 2018 protections for TUI customers: ✅ If TUI cannot operate your flight due to the SAERCO strike, they must offer you either:
Contact TUI: tui.co.uk | 0203 451 2688 (UK) — call your TUI rep, not the general helpline, if you are already in resort
Heathrow → Málaga, Alicante, Seville, Madrid, Barcelona, Valencia
British Airways’ Spain half-term network is primarily at Heathrow — serving Málaga, Alicante, Seville, Madrid, and Barcelona. Seville is a SAERCO airport. Madrid and Barcelona are Groundforce-only. BA’s Oneworld partnership means rerouting onto Iberia or Vueling is possible if BA cancels a Spain service — ask explicitly.
Contact British Airways: ba.com | 0344 493 0787 (UK) | BA app
As air traffic control strikes are classed as “extraordinary circumstances”, airlines are not usually required to pay compensation for delays or cancellations — although they must still offer rebooking or refunds. Routes
This means: ❌ No mandatory cash compensation for SAERCO ATC-caused disruptions ❌ No mandatory cash compensation for Groundforce-caused disruptions (contested — file anyway) ✅ Full refund or rebooking rights are ALWAYS available — regardless of cause ✅ Duty of care (meals, hotel, 2 communications) — MANDATORY regardless of cause
If your flight is CANCELLED: ✅ Full cash refund to original payment method within 7 days — mandatory under UK261/EU261 ✅ Rerouting on the next available service at no extra cost ✅ Rerouting at a later date of your convenience (if you prefer to delay your holiday)
If your flight is DELAYED 2+ hours: ✅ Meals and refreshments in proportion to wait time — ask explicitly at the check-in desk or gate; do not wait for the airline to offer ✅ 2 free phone calls or emails at airline’s expense
If your flight is DELAYED 5+ hours: ✅ Full refund of your ticket plus right to a return flight to your original departure point if you choose not to travel
Cash compensation under UK261 (£220–£520) can still apply where the airline had advance notice of the strike and failed to take reasonable measures — but this is legally contested for ATC strikes. The better argument for Groundforce:
Groundforce compensation argument: Groundforce is a third-party contractor employed by the airlines. Courts in several EU jurisdictions have found that a third-party ground handler’s strike can be within an airline’s operational control — because the airline chose to use that contractor and could have arranged alternatives. File a UK261 compensation claim for Groundforce-related cancellations. Worst case: rejection. Best case: £220–£520 per person.
File UK261 claims:
If you booked a package holiday (flight + hotel in one booking), the Package Travel Regulations 2018 give you significantly more protection than UK261 alone. Your tour operator has an obligation to: ✅ Notify you of significant changes at least 14 days before departure ✅ Offer a comparable alternative or full refund if the flight cannot operate ✅ Provide assistance if you are stranded during your holiday
Call your tour operator (TUI, Jet2 Holidays, First Choice, Thomas Cook) — not the airline — if your package holiday is affected. The operator has the liability, not just the airline.
Action 1 — Check your flight right now before leaving home. Open your airline’s app and confirm your flight is operating. Then go to flightaware.com and search your specific flight number. If the inbound aircraft hasn’t left the UK yet — your departure will be late. Do this before you leave for the airport, not when you arrive.
Action 2 — Canary Islands passengers — verify your slot has been confirmed. Lanzarote and Fuerteventura are at 34% ATC capacity. Your airline will only confirm your flight is operating if it has been allocated a slot in the minimum services window. If your airline app shows “delayed” rather than “on time” — call the airline before leaving for the airport. A 3-hour delay at the UK end is recoverable. A cancellation when you have already checked in your bags is not.
Action 3 — Travel carry-on only if your trip allows it. Today is Groundforce Monday at Palma, Málaga, Alicante, Tenerife, Barcelona, and Madrid. Carry-on only eliminates: Groundforce baggage loading delays, the risk of your bag staying behind, baggage reclaim delays on return, and the need to wait at the carousel. If you are flying to a hot-weather destination for a week — pack a cabin bag only. It is the single most effective disruption-prevention action you can take today.
Action 4 — If your SAERCO airport flight is cancelled — ask for rerouting via Madrid or Barcelona. If your Lanzarote or Fuerteventura flight is cancelled, ask your airline immediately: “Can you rebook me on a service via Madrid or Barcelona?” Both hubs are operating without SAERCO ATC restriction. Connecting routes (London→Madrid→Lanzarote) take longer but are significantly more likely to operate. Ryanair and easyJet will not proactively offer this — you must request it.
Action 5 — Know the Santiago reopening tomorrow. If your booking shows Santiago de Compostela (SCQ) — it was still closed yesterday but reopens tomorrow May 27. Ryanair Stansted–SCQ and British Airways Heathrow–SCQ are both expected to resume. Check your airline’s app for your specific departure date — the first week post-reopening will have limited capacity as airlines restore schedules.
Your last Spain ATC article was Day 22 (May 8). Here is a summary of what has happened in the 18 days since:
| Development | Status as of Day 40 |
|---|---|
| SAERCO talks | ❌ No fresh talks — no date set |
| Minimum services order | ✅ Still in force — ~34% lower-traffic capacity |
| Groundforce deal | ❌ No deal — Mon/Wed/Fri windows continue |
| Santiago SCQ closure | Closes April 23 — reopens TOMORROW May 27 |
| Spain government intervention | ❌ No compulsory arbitration — no licence threat |
| AENA considering replacing SAERCO | 🟡 Discussed in Spanish press — no confirmed timeline |
| UK May Bank Holiday (May 4) | Passed — some delays, no resolution |
| UK half term (May 25–29) | 🔴 ACTIVE NOW — peak disruption window |
| Summer season ahead | July–August Spain capacity at high risk if unresolved |
The most significant development since Day 14 is the absence of any development. The strike is indefinite and will continue until SAERCO and the unions reach a new agreement. At Day 40, the strike is no longer a crisis heading toward resolution — it is a structural feature of Spain’s summer aviation environment that every UK family with a July or August Spain booking needs to plan around. Travel And Tour World
Summer holidays in England and Wales run from approximately July 20 to September 2, 2026 — 6 weeks. Scotland breaks up from late June. Nomad Lawyer
If SAERCO Day 40 becomes SAERCO Day 70 — or Day 100 — by the time UK summer holidays begin, every family with Spain summer holidays booked faces the same disruption landscape that half-term families are navigating today.
The summer risk assessment:
The travel insurance warning: The SAERCO strike was announced on April 13 and began April 17. Any travel insurance purchased after April 13 that includes Spain has a “known event” exclusion — the insurer will reject strike-related claims because you purchased the policy after the strike was announced. This does not apply to insurance purchased before April 13. Check your policy dates. Fox News
Spain’s SAERCO ATC strike enters Day 40 on Monday May 26 — with no deal, no talks scheduled, and no end date. Today is simultaneously: the first working day of UK half term week, a Groundforce Monday with three active strike windows, and the peak outbound UK-to-Spain departure day. Lanzarote and Fuerteventura face the dual crisis they have carried since Day 1 — SAERCO ATC at 34% capacity plus Groundforce baggage handling disruption. Santiago de Compostela reopens tomorrow after 33 days. Madrid, Barcelona, Palma, Málaga, Alicante, and Tenerife are not SAERCO airports — ATC is normal there — but Groundforce Monday baggage disruption applies. EU261 and UK261 cash compensation does not apply to ATC strike disruptions — but refund rights, rebooking rights, and duty of care are absolute and non-negotiable for every cancelled or significantly delayed flight. TUI and Jet2 Holidays package customers hold additional protections under the Package Travel Regulations 2018. Travel carry-on only. Check FlightAware before leaving home. Know your duty-of-care rights — meals after 2 hours, hotel if overnight. And if you have July or August Spain bookings — buy travel insurance with strike cover now, before the known-event exclusion locks you out.
Day 40. No deal. Half term starts. The strike isn’t ending this week. Plan around it.
