Most Disrupted Airports in Europe 2025: Delay Rankings and EC261 Implications
Not all airports are equal when it comes to flight disruptions. Some — due to infrastructure limitations, geography, ATC constraints, or traffic volume — consistently generate more delays than others. If you regularly fly from a high-disruption airport, understanding the patterns helps you know when delays are genuinely extraordinary (and therefore not compensable) versus when they're predictable operational failures (very likely compensable).
This analysis combines Eurocontrol CODA (Central Office for Delay Analysis) ATFM data, national airport authority reports, and flight tracking aggregate statistics for 2025.
How Airport Disruption Is Measured
ATFM Delay: Air Traffic Flow Management delay — the delay imposed by Eurocontrol's Network Manager on flights at departure to avoid congestion at destination or en route. ATFM delay is measured in minutes per flight.
Ground Delay Programme (GDP) events: Periods when an airport implements flow control reducing arrival or departure rates.
Cancellation rate: Percentage of scheduled flights cancelled (weather, capacity, operational).
Average delay per departing flight: Including all delay causes (ATFM, airline, ground handling, weather).

Deep Dive: The Five Worst Airports for EC261 Claims
1. Athens (ATH) — Summer Congestion Capital
Athens generates the highest ATFM delays in Europe during June–September. Greek ATC (HCAA — Hellenic Civil Aviation Authority) has faced chronic capacity and staffing issues. The tourist influx to Greek islands — Santorini, Mykonos, Heraklion, Rhodes — funnels through ATH's limited ATC zone.
EC261 context: Athens ATC delays are predictable and seasonal. Courts across Europe have recognised that airlines operating to/from Greece during peak season are well aware of these conditions. Citing "Athens ATC restrictions" as extraordinary circumstances for a July delay is increasingly difficult to sustain.
Key airports nearby: Athens, Heraklion (HER), Rhodes (RHO), Mykonos (JMK), Santorini (JTR), Corfu (CFU) — all high-disruption.
2. Palma de Mallorca (PMI) — Tourism Saturation
Palma handles over 30 million passengers in summer from a relatively modest airport infrastructure. Slot saturation during July–August creates systematic late departures and cascading delays.
EC261 context: Palma summer delays are among the most foreseeable in European aviation. Airlines scheduling peak summer operations to Palma cannot credibly claim these disruptions are extraordinary.
3. Lisbon (LIS) — Infrastructure Bottleneck
Lisbon has been operating beyond its comfortable capacity for years. Debate over a new airport (Alcochete/Montijo) continues without resolution. LIS handles TAP's hub operations plus growing point-to-point traffic from Ryanair, easyJet, and others.
EC261 context: LIS delays are structural. TAP Air Portugal's use of "Lisbon ATC restrictions" as extraordinary circumstances has been challenged by multiple passengers and courts. The chronic, predictable nature of LIS congestion undermines the extraordinary circumstances defence for airlines that base there.
See our Lisbon Airport delays guide.
4. Paris CDG — Hub Complexity
CDG is Europe's second-busiest airport and Air France's main hub. Its complexity — multiple terminals, large aircraft mix, high long-haul volume — creates cascading delay potential. French labour relations add strike-related disruption.
EC261 context: CDG delays have multiple causes. Sudden ATC restriction: potentially extraordinary. Predictable summer congestion: not extraordinary. Air France strikes (pre-announced): generally not extraordinary under Krüsemann (C-195/17, 2018).
5. Gatwick (LGW) — Single Runway Constraint
Gatwick operates one of the world's busiest single runways. Any disruption — aircraft incident, weather, unusual traffic — immediately cascades across the entire schedule. easyJet and British Airways are primary operators.
EC261 context: Gatwick's single-runway constraint is inherent to its infrastructure. Courts have recognised that airlines operating there know this risk. Ordinary disruption at Gatwick is generally not extraordinary.
ATFM Delays vs EC261: When Does Airport Congestion Create a Claim?
This is the key question for passengers at congested airports:
| Delay Cause | Airline's Extraordinary Circumstances Claim | Courts' General View |
|---|---|---|
| Predictable seasonal ATC capacity | Yes | Rejected — foreseeable |
| Sudden unexpected ATC restriction | Yes | Often accepted — if genuinely sudden |
| Airport closure (weather, safety) | Yes | Generally accepted |
| Ground handler strike (pre-announced) | Yes | Generally rejected — Krüsemann |
| Technical fault on aircraft | Yes | Rejected — Wallentin-Hermann |
| Previous flight delayed (knock-on) | Yes | Only if original cause was extraordinary |
The critical test: was this disruption genuinely unforeseeable to an airline that had exercised all reasonable care? For airports listed in this guide, most seasonal delays fail this test.

Airports That Have Improved Most in 2025
Despite the congested airports above, some airports showed notable OTP improvement in 2025:
| Airport | 2024 ATFM min/flight | 2025 ATFM min/flight | Change |
|---|---|---|---|
| Amsterdam Schiphol | 10.4 | 8.1 | -2.3 min (improved) |
| Frankfurt | 11.2 | 9.4 | -1.8 min (improved) |
| Berlin Brandenburg | 5.8 | 5.1 | -0.7 min (improved) |
Schiphol's improvement reflects the operational stabilisation post-2022 crisis, though it remains above the European average.

Frequently Asked Questions
Q: My flight from Athens was 4 hours late due to Greek ATC. Can I claim? A: Probably yes. While Greek ATC delays are predictable seasonally, the question is whether the airline (a) had adequate notice of the specific restriction, (b) took all reasonable measures to mitigate, and (c) the restriction was genuinely unforeseeable for that specific day. Many Athens ATC delay claims succeed. Check your eligibility at /check.
Q: My Ryanair flight from Palma was cancelled due to "airport congestion." Is that extraordinary? A: Palma summer congestion is extremely foreseeable. Ryanair knows this better than anyone — they are among Palma's largest operators. Airport congestion at Palma in July is unlikely to constitute extraordinary circumstances. File your claim.
Q: Frankfurt ATFM delays are on this list — does that mean all Lufthansa Frankfurt delays are compensable? A: Not automatically, but Frankfurt ATFM delays that are predictable/seasonal don't give Lufthansa an extraordinary circumstances shield. Sudden, unforeseeable restrictions on a specific day are different. Each case requires assessment.
Q: I was delayed at both ends — departure and arrival airports were both congested. Does that double the claim? A: No. EC261 compensation is per flight, per passenger. Whether delay originated at departure or en route, you have one claim per disrupted flight.
Q: Does the airport's OTP ranking affect my claim at all legally? A: Not directly in legal terms, but the chronic, documented nature of delays at specific airports weakens the airline's "extraordinary, unforeseeable" argument. Evidence of systematic predictable disruption at that airport can be cited in your claim.
