Airline Strike & EU261: When You're Owed Compensation

How EU261 Handles Strike Disruptions

European aviation has seen repeated strikes since 2022. Pilots, cabin crew, ground handlers and air traffic controllers have all walked out, disrupting millions of passengers and forcing airlines to cancel or badly delay hundreds of flights each time. Strikes by Ryanair cabin crew in several countries, Lufthansa ground staff, and air traffic controllers in France and Greece have grounded hundreds to thousands of flights in a single day.

Under EU Regulation 261/2004 (EUR-Lex 32004R0261), airlines must pay up to €600 in cash compensation when a flight is cancelled or arrives more than three hours late. There’s one important exception: disruptions caused by “extraordinary circumstances” that the airline couldn’t have avoided even if it had taken all reasonable measures.

Strikes are a grey area. The Court of Justice of the European Union has ruled many times on which kinds of strike count as extraordinary, and the answers favour passengers more than airlines admit in their first reply to a claim.

It mostly comes down to one question: was the strike internal (the airline’s own employees) or external (air traffic controllers, airport security, or baggage handlers employed by someone else)?

Internal Airline Staff Strikes: Compensation Is Usually Due

When pilots, cabin crew or ground staff employed by the airline itself walk out, EU261 cash compensation is almost always owed. It doesn’t matter whether the walkout was spontaneous or organised by a union. Many passengers get this wrong. Airlines often send refusal letters citing extraordinary circumstances for internal strikes, knowing most passengers won’t challenge them.

The CJEU has dealt with this in two key rulings:

C-195/17, Krüsemann v TUIFly (17 April 2018): After TUIFly suddenly announced a large restructuring, its flight crew called in sick en masse. TUIFly called this an extraordinary circumstance. The court disagreed. A walkout caused by the airline’s own restructuring decisions is part of its normal business and within its control. The strike came straight from a decision management made. Compensation was due.

C-28/20, Airhelp v SAS (23 March 2021): SAS pilots held a union-organised strike over pay, following every legal procedure and giving advance notice. SAS argued that a formally announced union strike within the law was an extraordinary circumstance outside its control. The CJEU disagreed. A strike by the airline’s own pilots, even a lawful one announced in advance, is part of its normal operations and doesn’t meet the extraordinary circumstances test. Compensation was still due.

Many airlines cite C-28/20 in refusal letters to argue that formally organised union strikes exempt them from paying compensation. This is legally incorrect. The ruling confirmed the opposite: organised internal strikes are not extraordinary circumstances.

The court uses a two-part test for extraordinary circumstances: (1) is the event part of the airline’s normal operations, and (2) is it within the airline’s actual control? Internal strikes, spontaneous or union-organised, fail both parts for the airline. Pay negotiations, restructuring announcements and managing staff are all part of running an airline. They aren’t outside forces the airline can’t control.

If your flight was cancelled or more than three hours late because the airline’s own staff walked out, you’re entitled to:

EU261 cash compensation: €250, €400 or €600 depending on flight distance
Care and assistance under Art. 9: meals and refreshments while you wait, plus a hotel and transport to it if you’re stuck overnight
Rerouting or a full refund under Art. 8: rerouting at the earliest opportunity, or a full refund of your ticket

External Strikes: Cash Compensation Disappears, Rights Remain

Not every strike gets you EU261 cash compensation. When the strikers work for someone else, such as air traffic controllers, airport security staff, or fuel and ground-handling contractors working for the airport, the position changes.

External strikes are generally treated as extraordinary circumstances under Art. 5(3) of EU Regulation 261/2004. The airline has no control over air traffic control rosters, airport staffing or contractors it doesn’t manage. An ATC strike that grounds flights across a whole region of airspace is the clearest example. The disruption starts entirely outside the airline and hits every operator equally, however well each manages its own staff. For the full extraordinary circumstances test and the other events that qualify, see our guide to extraordinary circumstances under EU261.

What this means in practice:

EU261 cash compensation of €250–600 is not payable for disruptions caused by strikes at other companies.

Your rights to care and rerouting always apply:

Art. 9 (Care): Meals and refreshments in proportion to the wait, plus a hotel and transport to and from it if you’re stuck overnight.
Art. 8 (Rerouting or refund): Rerouting to your final destination under comparable conditions at the earliest opportunity, or a full ticket refund plus a return flight to your departure point if you no longer want to travel.

These rights apply whether or not the disruption counts as extraordinary. An ATC strike doesn’t allow the airline to leave you stranded without meals, a hotel or a realistic way to reach your destination. If the airline refuses care because the disruption was extraordinary, that refusal itself breaks the regulation. The extraordinary circumstances exemption only removes the duty to pay cash compensation. The duty of care stays.

The Practical Thresholds and Amounts

EU261 cash compensation applies when you arrive three hours or more late. The CJEU set this threshold in Sturgeon (C-402/07) and Nelson (C-581/10). The regulation itself doesn’t spell it out. The time that counts is when the aircraft door opens at your final destination. The scheduled arrival and the moment of touchdown don’t count.

Compensation amounts under Art. 7 of EU Regulation 261/2004 (EUR-Lex 32004R0261):

Flight distance	Cash compensation
≤1,500 km	€250
1,501–3,500 km	€400
>3,500 km	€600

Under Art. 7(2), the airline can cut compensation by 50% if it offers rerouting and you arrive within set limits: under two hours late (≤1,500 km), three hours (1,501–3,500 km) or four hours (>3,500 km), wherever the flight departed from.

Other timing rules:

From 2 hours (≤1,500 km), 3 hours (1,501–3,500 km) or 4 hours (>3,500 km): right to meals and refreshments begins (Art. 6/Art. 9)
Delay of 5 hours or more: you can choose a full refund plus a return flight to your departure point instead of continuing your trip (Art. 8)
Overnight disruption: hotel and transport to it (Art. 9)
Cancellation notified less than 14 days ahead: full compensation applies, subject to the extraordinary circumstances test and unless the airline offers rerouting within the time limits in Art. 5(1)(c)

Time limits for claims are set by national law and vary a lot between EU member states: for example, five years in France, three years in Germany, and six years in England and Wales under retained EU law for pre-Brexit departures. These periods differ by country and can change, so check the limit for your route before you claim.

How to Claim EU261 Strike Compensation: Step by Step

Most passengers can handle an EU261 claim without a lawyer. The most important step is working out what kind of strike it was. Everything else follows from that.

Work out the strike type. Check the airline’s disruption notice, news reports or messages about meals and hotels. Did the airline’s own pilots, crew or directly employed ground staff walk out? That’s internal, and compensation is very likely due. Was it ATC, airport security or handlers employed by the airport? That’s external: no cash compensation, but your rights to care and rerouting still apply.
Record the disruption. Keep your boarding pass, booking confirmation, any disruption notice or text from the airline, and a screenshot of the destination airport’s arrivals board or the airline’s app showing the scheduled and actual arrival time at your final destination. A board screenshot is the strongest record you can get, because it shows both times side by side and was published by the airport or airline itself. Flight status shows scheduled and reported arrival times for the flights GADUIN tracks.
Send the airline a written claim. Cite EU Regulation 261/2004 by name. For internal strikes, cite C-195/17 (Krüsemann) and C-28/20 (Airhelp v SAS) by case number. Airlines are much less likely to dismiss claims that cite the leading CJEU rulings. Send it by email with a read receipt, or by registered post, so you can prove you sent it.
Challenge a wrongful refusal. If the airline refuses by citing extraordinary circumstances for what looks like an internal strike, reply in writing. Name the CJEU ruling that applies, say you disagree with the legal basis for the refusal, and give them 14 days to pay. Keep copies of all letters and emails in date order.
Escalate to the National Enforcement Body or an ADR scheme. Every EU member state has an NEB, such as the Luftfahrt-Bundesamt in Germany, the DGAC in France and the CAA in the UK for eligible flights. Most member states also have approved alternative dispute resolution schemes that are free for passengers.
Allow six to eight weeks for the airline to reply, and two to four months for an NEB complaint. Most airlines reply to well-documented claims that cite the case law within the first window.

When EU261 Falls Short: Event Contracts as an Alternative

Whether you get EU261 compensation depends on a legal classification: was the strike extraordinary or not? Airlines often dispute even clear internal strikes, and the claim can drag on for months after the disruption is over. If the airline wins the extraordinary circumstances argument, or the strike really was external, you get no cash compensation, however long the delay or however many connections you missed.

GADUIN flight event contracts work differently. A GADUIN flight market has three outcomes and settles on exactly one: the flight arrived on time, it arrived more than 15 minutes late, or it was cancelled. It’s measured on the flight’s recorded arrival against its scheduled arrival, and the threshold was fixed when the market opened. Why the flight was disrupted, internal or external strike, wildcat or organised, makes no difference to settlement. Each share of the outcome that happened pays $1 in USDT, and every other share pays $0. You don’t file a claim, write to the airline or argue about extraordinary circumstances.

So event contracts work alongside your EU261 rights and don’t replace them. If you hold a position, you keep all your EU261 rights and can pursue both at once. If the EU261 claim succeeds, you get that on top of the contract payout. If the airline defeats the claim on extraordinary circumstances grounds, the contract has already settled on what actually happened to the flight. The market settles once the official arrival record is in, without waiting for the airline’s lawyers.

An event contract on GADUIN isn’t insurance, legal advice or a sports market. It’s a traded position that settles on the official transport record, under terms fixed before the market opened.
