Your flight is delayed and the airline blames a strike. The announcement offers little detail — just a vague reference to "industrial action" or "circumstances beyond our control." Should you accept that and go home empty-handed? Not necessarily.

Under EU Regulation EC 261/2004, whether a strike entitles you to compensation depends entirely on who is striking. The law makes a sharp distinction between strikes that are the airline's responsibility and strikes that fall outside the airline's control. Getting this right can mean the difference between €0 and €600 per passenger.
Internal Airline Strike — Compensation Is Owed
When the airline's own employees go on strike, this is not considered an extraordinary circumstance under EC 261/2004. You are entitled to the full compensation.
The European Court of Justice confirmed this principle in the landmark case Transportes Aéreos Portugueses (TAP) v Airhelp and subsequent rulings. The court found that a strike by the airline's own staff — pilots, cabin crew, ground handling teams, check-in staff — is a foreseeable and manageable risk that airlines must account for. Labour disputes are part of running an airline. The airline has tools to prevent or resolve them: collective bargaining, staffing strategies, reserve crews.
Airlines that fall under this rule when their own staff strike:
- Pilots refusing to fly (pilot strike)
- Cabin crew strike or work-to-rule action
- Ground handling staff employed directly by the airline
- Customer service or check-in staff employed by the airline
If your flight was delayed or cancelled because the operating airline's own employees were striking, you are entitled to:
| Flight distance | Compensation |
|---|---|
| Under 1,500 km | €250 |
| 1,500–3,500 km | €400 |
| Over 3,500 km | €600 |
This applies when the delay causes you to arrive at your final destination 3 or more hours late. For cancellations within 14 days of departure, compensation applies regardless of the arrival delay.
External Strike (ATC, Airport Workers) — Extraordinary Circumstances
When workers outside the airline's control go on strike, this does qualify as an extraordinary circumstance — and the airline is exempt from paying compensation under EC 261/2004.
The most common external strikes affecting flights:
Air Traffic Control (ATC) strikes: ATC strikes are the most disruptive external strike type, affecting entire regions or countries. When air traffic controllers walk out, airlines cannot legally operate flights in affected airspace. This is entirely outside the airline's control, and courts consistently treat it as a genuine extraordinary circumstance.
Airport security or ground handling strikes (third-party): If the airport's own security staff, border police, or third-party handling agents (not employed by the airline) go on strike, grounding flights or causing severe delays, this can qualify as extraordinary.
Air traffic management system failures or go-slows: A union action by national air traffic authorities that restricts capacity also typically qualifies.
In these cases, you are not entitled to EC 261/2004 cash compensation. However, the airline's duty of care obligations still apply — you must still be offered meals, refreshments, hotel accommodation if stranded overnight, and rerouting.
How Airlines Misuse the "Strike" Excuse
The grey area between internal and external strikes is fertile ground for airline dishonesty. Some airlines routinely use the word "strike" when the actual reason for the delay is something entirely different.
Common misrepresentations:
"Wildcat strike" by airline staff: Some airlines claim an unofficial or spontaneous walkout by their crew qualifies as an extraordinary circumstance because it was unexpected. EU courts have been sceptical of this argument — the airline's relationship with its own staff remains its responsibility.
Third-party contractor strikes misattributed to the airline: Conversely, if an airline outsources its ground handling to a contractor and that contractor's workers strike, the situation is more ambiguous. Courts have generally still treated this as the airline's sphere of responsibility, since the airline chose and manages the contractor.
Blaming "air traffic control" for an internal problem: Airlines sometimes mention ATC in delay communications when the real cause was their own operational failure. A flight that was already 90 minutes late due to crew issues and then received an ATC slot delay is only partly covered by the extraordinary circumstances defence.
Vague "industrial action" language: Airlines deliberately use broad language to obscure whether the striking workers were their own employees or third parties. Always ask for the specific cause in writing.
How to Fight a Wrongful Strike Refusal
If the airline rejects your compensation claim by citing a strike, here is how to push back effectively:
Step 1 — Request the specific cause in writing. Ask the airline to confirm in writing exactly which employees were on strike, who employed them, and why this constitutes an extraordinary circumstance under EC 261/2004. Vague responses are a red flag.
Step 2 — Cross-reference public information. Check aviation news, union press releases, and government communications for the date of your flight. ATC strikes are public events covered by the media. If there was no reported ATC or external strike on that date, the airline's claim is questionable.
Step 3 — Submit a formal complaint citing the case law. Reference the ECJ ruling in TAP v Airhelp and state clearly that you believe the delay was caused by the airline's own staff, not an external extraordinary circumstance.
Step 4 — Escalate to your National Enforcement Body (NEB). Each EU country has a designated authority responsible for enforcing EC 261/2004. In the UK it is the Civil Aviation Authority; in Germany the Luftfahrt-Bundesamt; in France the DGAC. NEBs investigate airlines' use of the extraordinary circumstances defence.
Step 5 — Use a professional claims service. AirHelp and similar services have extensive databases of flight disruption causes and legal precedents. They know when airlines are misclassifying strike types and how to challenge these decisions effectively. They work on a no-win-no-fee basis, so there is no financial risk to you.

Frequently Asked Questions
The airline said "industrial action by air traffic control" but I cannot find any ATC strike reported that day — what should I do?
Request written confirmation from the airline of the specific ATC authority and country involved. If no ATC strike can be independently verified for that date, the airline is likely misrepresenting the cause. File a claim and escalate if rejected.
My flight was cancelled due to a pilot strike. The airline offered me a voucher. Can I demand cash?
Yes. You have a legal right to cash compensation, not just vouchers. If the strike involved the airline's own pilots, the cancellation is not covered by extraordinary circumstances. You are entitled to €250–€600 in cash, plus the right to a full refund or rerouting.
If both the airline's staff AND ATC were on strike on the same day, what happens?
The airline must prove that the extraordinary circumstance (the ATC strike) was the actual cause of your specific delay — not the internal strike. If both were ongoing simultaneously, the causal chain matters. This is a complex fact-specific question where professional legal help is valuable.
I was stuck at the airport for 8 hours due to a strike — am I owed hotel accommodation?
Regardless of whether you qualify for compensation, the airline's duty of care applies during any lengthy disruption, including strikes. If you were not offered meals during the wait, or needed overnight accommodation, you can claim these costs back even if the compensation for the delay is blocked by extraordinary circumstances.
The airline only offered me a voucher and said the strike means they owe me nothing. Is that true?
"Nothing" is almost never accurate. Even when extraordinary circumstances block cash compensation, the airline still owes you care (meals, hotel if overnight, rerouting). And if the strike was by the airline's own staff, compensation is owed too. Challenge a "nothing" response in writing.
