Thousands of holidaymakers and business travelers are facing chaos after Dutch airline Transavia and KLM canceled hundreds of flights to and from Portugal following a wave of strikes by Portuguese air traffic controllers and ground staff. The disruptions, which began on Wednesday, have left hundreds stranded at airports across Europe, including Eindhoven, Amsterdam, and Lisbon, with many questioning whether they’re entitled to compensation under EU passenger rights.
The strikes, organized by the Portuguese Air Traffic Controllers Association (APAN) and the General Union of Workers (UGT), have caused widespread flight cancellations and delays, with Portuguese airspace experiencing significant operational restrictions. While the unions cite safety concerns and wage disputes as their primary grievances, the immediate impact has been felt most acutely by passengers whose travel plans have been upended.
For many travelers, the news comes as a bitter blow just days before the peak summer travel season. The European Commission’s passenger rights regulations provide clear protections in such situations, but understanding what constitutes “extraordinary circumstances” versus airline responsibility remains crucial. Here’s what you need to know about your rights, alternative options, and what happens next.
Understanding the Strikes and Their Impact
According to the European Civil Aviation Conference, the current strikes involve both air traffic controllers and ground handling staff at Lisbon’s Humberto Delgado Airport (LIS) and Porto Airport (OPO). The Portuguese government has classified the situation as “extraordinary circumstances” for aviation purposes, which has significant implications for passenger compensation claims.
KLM and Transavia, which operate extensive routes between the Netherlands and Portugal, have canceled approximately 300 flights this week alone, according to real-time flight tracking data. The Dutch airline group has stated that while they are working to restore normal operations, the strikes have created “unprecedented challenges” for their scheduling systems.
Key affected airports include:
- Eindhoven Airport (EIN) – Dutch hub with direct connections to Lisbon and Porto
- Amsterdam Schiphol (AMS) – Major KLM hub with extensive Portuguese routes
- Lisbon Humberto Delgado (LIS) – Primary Portuguese international airport
- Porto Francisco Sá Carneiro (OPO) – Second largest Portuguese airport
EU Passenger Rights: Are You Entitled to Compensation?
The critical question for stranded passengers is whether these strikes qualify as “extraordinary circumstances” under EU Regulation 261/2004. If they do, airlines are not required to provide compensation. However, if the cancellations were within the airline’s control, passengers may be entitled to between €250 and €600 in compensation plus reimbursement or rerouting.
According to the Portuguese Civil Aviation Authority (ANAC), strikes by air traffic controllers are generally considered extraordinary circumstances, meaning airlines would not be liable for compensation. However, the situation becomes more complex when considering:
- Union statements: APAN has stated the strikes are about safety concerns, not wage disputes, which could affect legal interpretations
- Government classification: The Portuguese government’s official designation of the situation is crucial
- Airlines’ response: Whether airlines could have implemented alternative measures
Transavia and KLM have both stated they are offering affected passengers alternative travel options, including rerouting through other European hubs. However, many travelers report difficulties in securing these alternatives, particularly for summer holiday travel.
What to Do If Your Flight Is Cancelled
If you’re affected by these cancellations, here are immediate steps to take:
1. Verify Your Status
Check with your airline directly using their official customer service channels. Both KLM and Transavia have dedicated pages for flight status updates:

2. Request Assistance
Under EU regulations, airlines must provide:
- Meals and refreshments
- Hotel accommodation if an overnight stay becomes necessary
- Transport between the airport and hotel
- Two phone calls or emails
Request these immediately if you’re stranded. Keep all receipts for expenses incurred.
3. Explore Rerouting Options
While strikes may limit immediate options, consider:
- Connecting through alternative European hubs (Paris, Madrid, Frankfurt)
- Using budget airlines that may have available capacity
- Temporary accommodation near the departure airport
4. Document Everything
For potential compensation claims, save:
- Flight confirmation emails
- Boarding passes
- Photos of cancellation notices
- Receipts for additional expenses
- Communication with airline customer service
Compensation Claims: What’s Likely?
Based on current information and legal precedents, here’s the most likely scenario:
- Strikes by air traffic controllers: Generally considered extraordinary circumstances → no compensation
- Strikes by airline employees: May be considered within airline’s control → potential compensation
- Delays vs. Cancellations: Compensation rules differ significantly between these scenarios
However, legal experts note that recent European Court of Justice rulings have shown increasing scrutiny of what constitutes “extraordinary circumstances.” The 2019 “Nelson” case set a precedent that airlines cannot automatically claim extraordinary circumstances without demonstrating they took all reasonable measures to avoid the situation.
If you believe your cancellation was within the airline’s control, you may submit a claim through:
- European Consumer Centre Network
- Portuguese Civil Aviation Authority
- KLM Complaints Portal
- Transavia Complaints Portal
Looking Ahead: What Happens Next?
The Portuguese government has stated We see working with unions to resolve the strikes as quickly as possible. However, with summer being the peak travel season, the situation could persist for several days. Here’s what to expect:

- Short-term (next 72 hours): Continued flight cancellations and operational restrictions
- Medium-term (1 week): Potential for partial restoration of services if strikes end
- Long-term (beyond 2 weeks): Possible compensation claims if strikes continue beyond reasonable periods
The European Civil Aviation Conference has indicated they are monitoring the situation closely and may intervene if the strikes begin to affect safety standards across European airspace.
Key Takeaways for Affected Travelers
- Compensation is unlikely for cancellations directly caused by Portuguese air traffic controller strikes, as these are considered extraordinary circumstances
- Alternative travel options are your best immediate recourse, though capacity may be limited during peak season
- Document everything in case legal interpretations evolve or if strikes continue beyond current expectations
- Check official sources for updates rather than relying on social media or unofficial channels
- Consider travel insurance if you need to make alternative arrangements, as some policies may cover additional expenses
