Summer 2025 has proven to be another challenging year for European air travel, with some of the continent’s busiest airports experiencing significant delays and cancellations. If you’ve been affected by disruptions at any of Europe’s worst-performing airports, you could be entitled to up to €600 in compensation under EU Regulation 261/2004. Here’s the definitive ranking of Europe’s most problematic airports in 2025 and what passengers need to know about claiming their rights.
European air travel disruptions in 2025 have reached concerning levels, with over 16% of flights affected by delays according to aviation analytics. While some delays stem from weather and air traffic control issues, many result from airport-specific problems that airlines should manage better. Understanding which airports consistently underperform helps travelers plan better and know when to expect compensation claims.
The 2025 European Airport Delay Rankings
Based on comprehensive data from aviation analytics firms, passenger rights organizations, and airline performance metrics, here are Europe’s most problematic airports for delays and cancellations in 2025.
1. London Gatwick (LGW) – United Kingdom
Delay Rate: 38% of flights delayed or cancelled
Average Delay: 45 minutes
Primary Causes: Air traffic control bottlenecks, staffing shortages, runway capacity constraints
London Gatwick has earned the unfortunate distinction of being Europe’s most unreliable airport in 2025. Despite serving as a major hub for British Airways, EasyJet, and numerous other carriers, the airport has struggled with persistent operational challenges.
Key Problems:
– Single runway operations creating cascading delays during peak periods
– Air traffic control staffing issues affecting departure slots
– Weather sensitivity due to runway configuration limiting operations during adverse conditions
– Ground handling delays from third-party service providers
Passenger Impact:
– Over 280,000 passengers affected by delays exceeding 3 hours
– Compensation claims potentially worth €42 million for affected passengers
– Missed connections leading to extended travel disruptions
EU261 Implications:
Most Gatwick delays stem from operational issues within airline control, making them compensable under EU261. Air traffic control delays may qualify as extraordinary circumstances, but airlines must prove specific ATC instructions caused their individual flight delays.
2. Istanbul Airport (IST) – Turkey
Delay Rate: 34% of flights delayed or cancelled
Average Delay: 52 minutes
Primary Causes: Weather challenges, rapid expansion growing pains, air traffic management
While Turkey isn’t an EU member, Istanbul Airport affects millions of European passengers annually through connecting flights and European airline operations.
Key Problems:
– Weather-related closures during winter months affecting European connections
– Ground handling bottlenecks during peak summer season
– Air traffic coordination issues between European and Middle Eastern flight paths
– Rapid capacity expansion outpacing operational infrastructure
EU261 Implications:
– Flights departing from EU airports TO Istanbul remain covered by EU261
– European airlines like Lufthansa operating IST connections must provide compensation
– Turkish Airlines flights from EU airports to Istanbul qualify for compensation
3. Frankfurt Airport (FRA) – Germany
Delay Rate: 32% of flights delayed or cancelled
Average Delay: 41 minutes
Primary Causes: Labor strikes, technical system failures, air traffic control capacity
As Europe’s busiest cargo hub and second-busiest passenger airport, Frankfurt’s problems ripple across the entire European network.
Key Problems:

– Air traffic control congestion over the Mediterranean
– Limited runway capacity for the volume of traffic
– Ground handling delays during peak departure periods
EU261 Success Stories:
“Vueling delayed our Barcelona to Rome flight by 4 hours, claiming ‘air traffic control.’ We proved it was actually a crew scheduling problem and received €400 compensation.” – James K., Barcelona passenger
6. Amsterdam Schiphol (AMS) – Netherlands
Delay Rate: 28% of flights delayed or cancelled
Average Delay: 33 minutes
Primary Causes: Staffing shortages, security delays, runway maintenance
Schiphol’s reputation for efficiency has suffered significantly in 2025 due to post-pandemic recovery challenges.
Key Problems:
– Security staff shortages creating passenger processing delays
– Baggage handling issues causing departure delays
– Runway maintenance reducing operational capacity
– KLM operational challenges affecting the hub carrier
EU261 Implications:
Many Schiphol delays stem from airport service issues rather than airline problems, but airlines remain responsible for crew management and technical problems occurring at the airport.
7. Rome Fiumicino (FCO) – Italy
Delay Rate: 27% of flights delayed or cancelled
Average Delay: 39 minutes
Primary Causes: Strike actions, air traffic control, ground services
Italy’s primary international gateway continues struggling with infrastructure and labor challenges.
Key Problems:
– Ground service strikes affecting multiple airlines

– Security processing delays during peak periods
– Weather impacts on closely-spaced parallel runways
Recent Disruptions:
September 2025’s cyberattack affecting check-in systems caused massive delays, demonstrating Heathrow’s vulnerability to technical failures despite generally strong operations.
Understanding Delay Causes and Your Compensation Rights
Compensable Delays (Airlines Must Pay)
Airport-Related but Airline-Controlled:
– Crew scheduling problems at any airport
– Aircraft technical issues regardless of location
– Airline ground handling delays (when airline controls service)
– Fuel loading delays or aircraft cleaning issues
Example: Your Lufthansa flight from Frankfurt is delayed 4 hours because crew reached maximum duty time. Despite Frankfurt’s general delay problems, this specific cause is airline-controlled and compensable.
Potentially Non-Compensable Delays
Extraordinary Circumstances:
– Air traffic control strikes affecting all airlines
– Weather conditions preventing safe operations
– Security incidents closing airport areas
– Government-imposed restrictions
Example: French ATC strike delays your Air France flight from CDG by 5 hours. This may qualify as extraordinary circumstances, but airlines must prove the strike directly caused their specific delay.
Geographic Compensation Strategies
Choosing Alternative Airports
London Area:
– Consider Stansted (STN) or Luton (LTN) instead of Gatwick
– Both typically have better punctuality records
– May require longer ground transport but offer more reliable schedules
Paris Area:
– Orly (ORY) often performs better than Charles de Gaulle
– Limited long-haul options but good European coverage
– Consider train connections from other French airports
German Alternatives:
– Düsseldorf and Hamburg often outperform Frankfurt and Munich
– Consider connecting through Amsterdam or Zurich instead
Booking Strategies for High-Delay Airports
Allow Extra Connection Time:
– Minimum 2-3 hours for connections at problem airports
– Book later outbound flights to accommodate delays
– Consider overnight stops for tight international connections
Choose Morning Flights:
– Delay cascades worsen throughout the day
– Early departures have better on-time performance
– Fewer air traffic control restrictions in early hours
Select Hub Airlines Carefully:
– Airlines with major operations at problem airports may have better ground support
– But they’re also more affected by airport-wide issues
– Consider bypass strategies using alternative carriers
Filing Claims for Airport-Related Delays
Documentation Strategy
Prove Airline Responsibility:
Airport delays don’t automatically excuse airlines from compensation. Collect evidence showing:
– Specific delay cause was airline-controlled
– Other airlines operated normally during same period
– Airline failed to use reasonable alternative measures
Key Evidence:
– Flight tracking data showing delay reasons
– Airport announcement recordings or photos
– Comparison with other airlines’ performance
– Airline crew or gate agent statements about delay causes
Common Airline Excuses and Responses
“Airport Delays Were Outside Our Control”
Response: “Please specify which exact airport service caused the delay and provide evidence that all reasonable alternative measures were taken.”
“Air Traffic Control Caused All Delays”
Response: “Please provide ATC slot confirmation showing specific restrictions on your flight and proof that other airlines were equally affected.”
“Weather Made Operations Impossible”
Response: “Please provide meteorological reports and explain why other airlines continued operating during the same period.

Your Action Plan for High-Delay Airports
Before Travel
1. Research your departure airport’s recent performance
2. Book early morning flights when possible
3. Allow generous connection times at problem airports
4. Consider alternative airports for important trips
5. Understand your compensation rights before delays occur
During Delays
1. Document everything – delay announcements, gate information, crew statements
2. Ask specific questions about delay causes
3. Keep receipts for meals, accommodation, transport
4. Don’t sign waivers or accept vouchers as final settlement
5. Demand care services the airline owes you during delays
After Travel
1. File compensation claims promptly regardless of delay cause
2. Challenge airline excuses with specific evidence
3. Use professional help for complex cases at problematic airports
4. Share experiences to help other passengers understand their rights
The Bottom Line: Poor Airport Performance Doesn’t Excuse Airlines
Europe’s worst-performing airports create challenging conditions, but they don’t automatically excuse airlines from their compensation obligations under EU261. Many delays that airlines attribute to “airport operations” actually stem from airline-controlled factors like crew management, technical maintenance, and ground handling coordination.
Key takeaways for passengers:
– Airport delay rates help predict but don’t determine compensation eligibility
– Specific delay causes matter more than general airport performance
– Airlines must prove extraordinary circumstances with specific evidence
– Professional claim services understand airport-specific delay patterns and airline tactics
Don’t let airport reputation discourage you from claiming rightful compensation. Whether you’re delayed at chaotic Gatwick or efficient Heathrow, your EU261 rights remain the same and airlines remain responsible for delays within their control.
