Flight Canceled Due to Strike? When You Can (and Can't) Get Compensation

EU261 and UK261 contain an 'extraordinary circumstances' defense: an airline is not required to pay fixed compensation if the disruption was caused by something outside their control that could not have been avoided even if all reasonable measures had been taken. This defense has been heavily litigated and is far narrower than airlines claim.

The European Court of Justice has repeatedly rejected broad extraordinary circumstances arguments. Mechanical issues, crew shortages, late inbound aircraft, and most airline operational problems do not qualify. But some external events -- genuine severe weather, ATC decisions, security incidents, and certain types of strike action -- can qualify.

Extraordinary circumstances never eliminate your refund right. Even if the airline successfully proves extraordinary circumstances and avoids paying the fixed €600/£520 compensation, you are still entitled to a full refund of your ticket and to duty of care (meals, hotel) during the delay.

In a landmark 2018 ruling (Helga Krüsemann v TUIfly), the Court of Justice of the EU ruled that a strike organized by the airline's own cabin crew is not extraordinary circumstances under EU261 when it is called in response to the restructuring decisions made by the airline itself. The court found that such a strike is inherent in the normal exercise of the airline's business activities.

This ruling covers strikes by pilots, cabin crew, and other airline employees. If Ryanair pilots strike, if Lufthansa cabin crew walk out, or if British Airways ground staff take industrial action over pay or conditions -- that is an internal airline matter and the extraordinary circumstances defense generally does not apply. Passengers are entitled to full EU261/UK261 compensation.

Airlines frequently misapply the extraordinary circumstances defense to their own staff strikes. If your airline canceled your flight citing 'industrial action' or 'strike' and refused EU261 compensation, challenge this denial -- the 2018 CJEU ruling is on your side for airline-internal strikes.

Strikes by air traffic controllers (ATC) are treated differently. ATC is an external service that airlines depend on but cannot control. A strike by French ATC workers that grounds flights at CDG can qualify as extraordinary circumstances under EU261, as the airline took no action that caused the strike and has no control over ATC staffing decisions.

Similarly, a wildcat strike by airport ground handlers (a third-party supplier, not airline employees) at the departure airport may qualify as extraordinary circumstances if the airline had no reasonable opportunity to anticipate or mitigate the disruption.

The key distinction is: airline's own employees on strike = likely not extraordinary circumstances. External parties (ATC, airport authority, third-party ground handlers) on strike = potentially extraordinary circumstances.

US DOT rules do not have an extraordinary circumstances defense for refund purposes. If your US-departing flight is canceled for any reason -- including a strike -- and you choose not to travel, you are entitled to a full cash refund. The cause of the cancellation is irrelevant to the refund right.

However, US DOT does not mandate fixed compensation for cancellations in the same way EU261 does. The refund covers your ticket cost, but you would not typically recover a separate compensation amount above the ticket price for a US domestic cancellation due to a strike.

Regardless of whether extraordinary circumstances apply to your specific strike situation, you always retain these rights under EU261/UK261:

• ›

  Full refund of your ticket price if you choose not to travel.

• ›

  Re-routing to your destination at the earliest opportunity on comparable transport.

• ›

  Duty of care: meals and refreshments for delays of 2+ hours; hotel and transport for overnight delays.

The extraordinary circumstances defense only affects whether the airline must pay the fixed €250-€600 / £220-£520 compensation on top of these base rights. It does not affect refunds, re-routing, or duty of care.

File your EU261 compensation claim stating the flight details and the reason given for the cancellation. If the airline denies your claim citing extraordinary circumstances due to a strike, request written documentation specifying: which party was on strike, when the strike was announced relative to your flight, and what measures the airline took to avoid the disruption.

For airline-internal strikes (pilots, cabin crew, ground staff employed by the airline), challenge the extraordinary circumstances defense by referencing the Krüsemann ruling and citing that internal strikes are not extraordinary circumstances under EU261. Escalate to the national aviation authority if the airline refuses.
