The situation
A claim was submitted against Iberia following a significant flight delay. The passenger arrived late enough to qualify for compensation under EU261. The claim was straightforward and submitted through the airline's official process.
Iberia rejected the claim. Their explanation was that the delay was caused by weather conditions, and therefore no compensation was owed.
The airline's explanation
Iberia relied on a common defense. They stated that weather affecting a previous flight caused a knock-on delay, and that this qualified as an extraordinary circumstance outside their control.
This type of response is frequently used in airline delay compensation claims. It sounds definitive, and most passengers assume it ends the process.

Why this matters under EU261
Not all weather qualifies as an extraordinary circumstance.
Under EU261, the airline must show that:
The issue directly affected the flight in question
The situation was outside their control
And it could not have been avoided with reasonable measures
A delay caused by an earlier flight does not automatically meet this standard. Operational knock-on effects, including aircraft rotation and scheduling, remain the airline's responsibility.
This is where many valid EU261 claims are incorrectly denied.
What we did
We did not accept the rejection. Instead, we evaluated whether the airline's reasoning actually met the required legal standard. It did not.
At that point, the claim moved beyond airline-level handling. It was escalated and prepared for enforcement.

Outcome
The airline maintained its position. We proceeded to litigation. The court ruled in favor of the passenger, and compensation was awarded.
Lesson
"Weather" is one of the most common reasons airlines use to deny compensation. It is also one of the most commonly misapplied.
A weather-related denial is not automatically valid. It must meet a strict legal threshold. If it does not, the claim remains enforceable.
Why most passengers lose here
Most passengers stop after the first rejection. The explanation sounds technical and authoritative. There is no clear indication that it can be challenged, and no obvious next step. That is exactly why this approach works.
Valid claims are often lost because they are not pursued beyond the airline's initial response.
Bigger picture
Airlines do not need to be fully correct in their first response. They only need to be convincing enough that the claim is not challenged.
When the explanation is tested against the actual legal standard, the outcome often changes. This is the difference between a rejected claim and a successful one.
