Airlines frequently use "adverse weather" as a blanket excuse to avoid paying up to €600 per passenger under Regulation EC 261/2004 (and the post-2025 UK Passenger Rights framework). However, in 2026, air passenger rights have evolved. If the airport remained operational but your flight was grounded, the cause was likely operational, not meteorological.
At Aireclaim, we bridge the information gap by cross-referencing your flight status with real-time aviation weather reports (METAR) to prove when an airline is misrepresenting the truth.

1. What Constitutes an 'Extraordinary Circumstance' in 2026?
Under current legal precedents (including the updated Wallentin-Hermann standards), weather only excuses an airline if the event was unavoidable even if all reasonable measures were taken.
- Routine Weather is NOT an Excuse: Normal winter snowfall in Helsinki or typical autumn fog at Schiphol are "inherent in the normal exercise of the activity of the air carrier."
- The 2026 Standard: If the airline failed to secure enough de-icing fluid or didn't have sufficient crew with "low-visibility" training, the delay is compensable. The weather was the catalyst, but the airline's lack of preparation was the cause.
2. The Adjacency Test: Forensic Proof for Your Claim
The Adjacency Test is the gold standard for dismantling airline excuses. It uses comparative data to prove that the "weather" didn't stop other flights—it only stopped yours.
How to Conduct an Adjacency Check:
- Temporal Window: Analyze departures and arrivals within ±120 minutes of your scheduled slot.
- Equipment Peer Review: If you were flying a Boeing 737-800 and other 737s or A320s took off from the same runway, the weather was within the aircraft's safety limits.
- The "Selective Cancellation" Indicator: In 2025, a landmark case proved that if more than 30% of scheduled flights at a terminal departed successfully, a weather-based "global" excuse is invalid.
3. Decoding METAR: The Data Airlines Hide
Pilots don't use "weather apps"; they use METAR (Meteorological Aerodrome Reports). These hourly codes tell the real story.
Weather Variable | Airline Claim | The METAR Reality (Claimable) |
Visibility | "Dangerous Fog" | If METAR shows RVR > 550m, Category II/III equipped aircraft can land. |
Wind | "Severe Gusts" | If the Crosswind Component is < 30 knots, most commercial jets are safe to operate. |
Precipitation | "Airport Closed" | If the METAR doesn't show +SN (Heavy Snow), the airport usually remains open with de-icing. |

4. Common Airline Tactics & How to Counter Them
As low-cost carriers face rising costs in 2026, "weather-washing" claims have risen by 40%. Here is how to fight back:
- The "Knock-on" Effect: The airline claims your flight is delayed because the previous flight was delayed by weather. The Law: This is rarely an extraordinary circumstance for your flight. The airline must maintain a "reserve" of aircraft.
- The "ATC Instruction" Myth: They blame Air Traffic Control. The Counter: If the ATC restriction was due to the airline's inability to provide a de-iced plane on time, the airline is liable.
FAQ: Weather Compensation Myths (2026 Edition)
Can I claim compensation if it was snowing but other flights departed?
Yes. This is a classic case where the Adjacency Test applies. If other airlines managed to take off or land during the same window, it proves that the airport infrastructure was fully operational. In this scenario, your flight’s cancellation wasn't caused by "inclement weather" but by your airline's operational failure—such as a shortage of ground staff, lack of de-icing fluid, or poor crew scheduling. Under EC 261/2004, these are not "extraordinary circumstances," and you are likely owed up to €600.
Can I claim if the weather was bad at the departure airport but fine at the destination?
Yes. It doesn't matter where the weather was; what matters is whether it was actually prohibitive. We analyze the flight path and airport capacity to see if the airline chose to cancel for economic reasons.
How much compensation can I get for a 4-hour weather delay?
Depending on the distance:
- €250 for flights under 1,500km.
- €400 for flights between 1,500km and 3,500km.
- €600 for long-haul flights over 3,500km.
Does "Air Traffic Management" (ATM) weather count?
Only if the restriction applied to all slots. If the airline simply "missed" their slot due to slow boarding and then blamed weather, you are owed compensation.
Conclusion: Don't Take "No" for an Answer
Airlines count on passengers not having access to METAR data or the technical knowledge to challenge them. We turn the tables using the same data the pilots use.
