Published on : 30 Apr 2026
Two weeks ago today, SAERCO air traffic controllers walked out at midnight. They are still out.
Day 14 is a milestone. Not because anything dramatic happened overnight — no deal was signed, no talks were announced, no suspension was declared — but because 14 consecutive days marks two full weeks of indefinite strike action with zero movement toward resolution. SAERCO and the unions have not announced fresh talks, and controllers have indicated the action will continue until a new agreement is reached. The dispute that was supposed to last a few disrupted days has become a structural feature of Spain’s aviation landscape.
And today adds its own particular pressure. Wednesday April 30 is a Groundforce strike day — which means Lanzarote and Fuerteventura are once again carrying the dual crisis that has been the defining characteristic of this entire emergency: SAERCO ATC minimum services running alongside the indefinite Groundforce ground-handling mandate with partial walkouts every Monday, Wednesday and Friday. Two independent strike actions. Two critical airport functions. Both disrupted. Simultaneously. At the UK’s two most popular Canary Islands destinations.
But the news that will define this article for the most readers is neither the two-week milestone nor today’s Groundforce window. It is what is five days away: the UK May Bank Holiday weekend.
The UK May bank holiday falls on Monday May 5, 2026. The associated travel weekend runs May 2–5. This is one of the busiest four-day Spain travel windows of the entire year — equivalent in UK leisure aviation terms to a mini-Easter weekend. Every Jet2, Ryanair, easyJet, and TUI flight to the Canary Islands, mainland Spain, and the Balearics during that period is at elevated disruption risk if the SAERCO strike continues.
The strike shows no sign of ending before May 2.

Fourteen days ago, the SAERCO strike was a crisis with an uncertain timeline. Today, it is a structural feature of Spain’s aviation environment with a clear prognosis: this dispute will not resolve quickly, and the reasons have been consistent since Day 1.
The walkout was 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 that controllers say are pushing workloads beyond safe limits, compulsory on-call shifts and last-minute roster changes that they argue breach their collective agreement, and concerns about operational fatigue and aviation safety.
None of those demands have changed. None of SAERCO’s positions have changed. No mediator has been appointed to restart talks. No Spanish court has issued a suspension order. No government minister has intervened with a proposal capable of bridging the gap.
The structural explanation makes this prognosis clear. 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.
Two-week damage assessment: Spain’s Ministry of Transport estimates that around 20,000 scheduled flight movements and 2.6 million passengers could be disrupted in the first month alone. With 14 of those 30 days now elapsed, approximately 9,300 flight movements and 1.2 million passengers have already been affected. The second half of the first month — including the May Bank Holiday weekend — remains ahead.
What a month-two extension means: If the strike runs into May and June, the impact accumulates into Spain’s peak summer aviation season. Lanzarote and Fuerteventura operate their maximum UK-facing schedules in June, July and August — when every Jet2, TUI and easyJet aircraft at those airports is carrying a full load of summer holiday passengers who booked many months ago. The Canary Islands have no realistic alternative to flying for the vast majority of international visitors. When a flight is cancelled, the next available flight is not today or tomorrow — it is the next scheduled departure, which on a suppressed ATC capacity schedule may be 2–3 days away.
Wednesday is the second Groundforce strike day of this working week. Today’s three windows are active unless a suspension has been confirmed since last night.
05:00–07:00 — Early morning window The most dangerous window for passengers booked on early-departure Ryanair services. Ryanair typically operates its first Lanzarote and Fuerteventura departures from 07:00–08:30. During the 05:00–07:00 window, baggage handlers may be absent — meaning aircraft pushed back at 07:15 depart without checked bags loaded. At the same time, ATC minimum services mean departure slot allocation is limited — aircraft queue longer for clearance. Both constraints hitting simultaneously.
11:00–17:00 — Six-hour midday peak The longest and highest-volume window. Every Jet2 and TUI midday departure falls within this band. Every easyJet afternoon service. Every Ryanair midday charter. Aircraft operating 45–60 minute turnarounds cannot absorb ATC slot delays and missing ground handling simultaneously. The choice for airlines: wait for bags (and miss the ATC slot), accept the ATC slot (and depart without bags), or cancel the sector. All three outcomes happen on Wednesday window days.
22:00–midnight — Late evening Final Ryanair sectors. Crews approaching duty time limits after a day of ATC-induced delays face increasing cancellation risk during this window. An aircraft that should have departed at 21:30 and is still on the ground at 22:15 due to the combination of afternoon ATC delays and the window-start baggage disruption is a near-certain cancellation.
The check you must do right now: Open your airline’s app or go directly to your airline’s website and search for a Spain ATC or Spain disruption travel advisory. Ryanair, easyJet, Jet2 and TUI all update these advisories during active strike periods. If a Groundforce suspension for today has been announced, it will appear there. If no suspension is shown, treat all three windows as live at Lanzarote and Fuerteventura.

This is the section every UK passenger with a May Spain booking needs to read carefully.
The UK Early May Bank Holiday is Monday May 5. The travel weekend runs Friday May 2 through Monday May 5 — four days. This is one of the busiest four-day Spain travel windows of the entire year. Every Jet2, Ryanair, easyJet, and TUI flight to the Canary Islands, mainland Spain, and the Balearics during that period is at elevated disruption risk if the SAERCO strike continues.
Each day of that weekend carries its own specific risk profile:
Saturday May 3 — The Highest Risk Day of the Long Weekend May 3 is the first peak-summer Saturday Jet2/TUI changeover day at Lanzarote and Fuerteventura. This is the Saturday that opens the summer package holiday season in earnest — when tens of thousands of UK families begin their two-week summer holidays. If the SAERCO strike is still running on May 3, this will be the single highest-impact day of the entire crisis for UK holiday passengers.
Saturday is not a Groundforce strike day (Mon/Wed/Fri pattern), which means May 3 carries only SAERCO ATC minimum services — not the dual crisis. But a high-volume Saturday under ATC minimum services, with every Jet2 and TUI aircraft cycling through Lanzarote and Fuerteventura on compressed turnaround times, produces the same cascade pattern seen on the April 18 peak Saturday. The afternoon delay build-up will be significant.
Friday May 2 — Bank Holiday Departure Surge (Groundforce Window) Friday is a Groundforce strike day. Friday May 2 is one of the highest-volume outbound UK days of the year — everyone leaving for the bank holiday weekend heads to the airport on Friday. Lanzarote and Fuerteventura flights on Friday May 2 face the dual crisis: SAERCO ATC minimum services AND Groundforce Friday windows. This is the highest-risk individual day of the bank holiday period.
Monday May 5 — UK Bank Holiday (Groundforce Window) Monday is a Groundforce strike day. May 5 is the UK bank holiday — historically one of the three or four highest inbound volume days at Lanzarote and Fuerteventura of the entire year, as thousands of families return from the bank holiday weekend. SAERCO ATC + Groundforce Monday windows. Dual crisis again.
Sunday May 4 — Return Day Sunday is not a Groundforce day, but SAERCO ATC remains active. This is a high-volume return day — passengers who flew out Saturday returning. The same cascade mechanics as every previous Sunday of the strike apply.
What to do if you have a May Bank Holiday booking:
✅ Check your airline’s Spain ATC disruption waiver today. Ryanair, easyJet, Jet2 and TUI have been issuing rolling waivers since Day 1. If a waiver is active covering May 2–5 and your airline is offering fee-free date changes, moving to a Tuesday (May 6) or Wednesday (May 7) departure removes both the peak Saturday volume risk and the Monday/Friday Groundforce window risk.
✅ If you are a Jet2 Holidays or TUI package customer: Call your tour operator today. The May Bank Holiday weekend is exactly the type of period where UK Package Travel Regulations most powerfully protect you. If the SAERCO strike is still active when you are due to depart — and it almost certainly will be — you have the right to ask your operator for an alternative comparable package or a full cash refund.
✅ Book travel insurance now if you haven’t already. The critical caveat: bought insurance before approximately April 7–8, 2026: you very likely have strike coverage. Bought insurance after approximately April 7–8, 2026: the strike was already a known event — most policies exclude known events from strike coverage. If you do not have insurance covering this strike, the practical protective action is the tour operator claim route (for package customers) or the airline waiver route (for independent travellers).
Passengers planning European travel beyond Spain should note a significant additional disruption event confirmed on the horizon: the Brussels Airport security strike on May 12, 2026. While TravelTourister’s full Brussels article is already published, the brief summary for Spain passengers using Brussels as a connection hub:
50% of Brussels Airport departures are expected to be cancelled on May 12. Approximately 60,000 passengers are at risk. This affects any UK passenger routing through Brussels Airport to Spain or elsewhere in Europe on May 12. If you have a British Airways, Brussels Airlines, Ryanair, or any other carrier booking through Brussels on May 12, check your booking now.
The Brussels and Spain ATC strikes are independent events — but they overlap in the calendar in a way that creates a uniquely risky two-week period for UK European travel: Spain ATC through the entire period, Groundforce Mon/Wed/Fri, Brussels May 12, and the UK bank holiday weekend all compressed into the same 12-day window.
The SAERCO strike has been running for 14 days. Comparable ATC disputes in Spain — and there have been several in the past decade — typically run for 3–8 weeks before either a negotiated agreement or a government-mandated resolution. Similar disputes in 2023 and 2024 were only resolved after several weeks of rolling cancellations.
If the pattern holds, the SAERCO strike could run through mid-to-late May. That covers:
The alternative routing option that most passengers don’t know about:
Passengers booked to Lanzarote (ACE, SAERCO) have a viable AENA-operated alternative: Gran Canaria (LPA), which uses ENAIRE controllers and is completely unaffected by the SAERCO strike. Gran Canaria is served by Ryanair, easyJet, Jet2 and TUI from most UK airports. The ferry from Las Palmas de Gran Canaria to Arrecife (Lanzarote) takes approximately 1 hour 15 minutes with Fred Olsen Express and runs multiple times daily. A rerouting via Gran Canaria adds approximately 2 hours to the journey but removes all SAERCO ATC risk entirely.
Similarly, passengers booked to Fuerteventura (FUE, SAERCO) can consider routing via Gran Canaria (LPA, AENA) and taking the Fred Olsen or Naviera Armas fast ferry to Morro Jable (Fuerteventura south) — approximately 1 hour 15 minutes. Not ideal, but a complete bypass of the SAERCO disruption.
For Sevilla (SVQ, SAERCO): the AVE high-speed train from Madrid Atocha to Sevilla Santa Justa takes 2.5 hours and is completely unaffected by ATC strikes. Madrid-Barajas (MAD) uses ENAIRE/AENA controllers and is not affected by SAERCO. If your Sevilla booking is flexible enough to reroute via Madrid and AVE rail, this removes all SAERCO risk for the Spanish leg of your journey.
This has not changed in 14 days and will not change. An ATC strike is classed as an extraordinary circumstance under EU261 case law because the airline does not employ the controllers and cannot prevent the disruption. That means the fixed €250–€600 cash compensation for long delays and cancellations is not payable during the SAERCO strike.
The sole exception: If your flight was delayed or cancelled during the strike window but the airline’s own records show the real cause was a crew shortage, a technical fault, or another airline-side issue, the extraordinary circumstances defence does not apply and you can still claim. Ask for the specific reason in writing.
If your flight is cancelled, you are entitled to a full cash refund within 7 days to your original payment method. Airlines cannot insist on a voucher. Invoke Article 8 directly: “I am invoking my right to a full cash refund under EU Regulation 261/2004 Article 8.”
At 2+ hour delay: Go to the check-in or gate desk immediately. 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 whether or not vouchers are provided.
At overnight cancellation: Ask the airline to arrange hotel accommodation. If they fail and you book independently, keep the receipt and document that airline-arranged accommodation was unavailable.
If your flight arrives without your checked bags: file a Property Irregularity Report (PIR) at the baggage desk before leaving the airport. You need the PIR reference number for all subsequent claims. Do not leave without it.
Call your tour operator — not the airline. Under the UK Package Travel and Linked Travel Arrangements Regulations 2018, if your package is significantly affected, you are owed either an alternative comparable package or a full cash refund. This protection does not have an ATC strike exemption — it applies regardless of the cause of disruption.
