Extraordinary Circumstances Challenge Letter Template & Generator

If you need to challenge airline claim that delay was due to extraordinary circumstances, a written letter is the recommended first step — it creates a clear record and shows you're pursuing the matter formally. Below is what a strong extraordinary circumstances challenge should include, plus a free tool to generate yours.

What this letter needs to cover

• Reference the Wallentin-Hermann case establishing that technical faults are not extraordinary circumstances
• State the specific reason given and why it does not meet the legal threshold
• Request reconsideration and payment of full UK261 compensation within 14 days

Why "extraordinary circumstances" claims deserve scrutiny

Airlines don't have to pay compensation under UK261 if a delay or cancellation was caused by genuinely extraordinary circumstances beyond their control — but this is a specific legal test, not a blanket excuse, and airlines sometimes apply it too broadly. Technical faults, for example, are generally not considered extraordinary unless they stem from something outside the airline's normal operational control, like a manufacturing defect discovered through no fault of the airline.

What to include before you send it

• Your flight details and the airline's stated reason for the delay or cancellation
• Why you believe this doesn't genuinely meet the extraordinary circumstances test
• Reference to relevant case law or CAA guidance if you're aware of comparable rulings
• A clear restatement of your compensation claim under UK261

What genuinely counts as extraordinary

Examples that generally do qualify include severe weather, air traffic control restrictions, security risks, or strikes by third parties (not the airline's own staff). Routine technical faults, staffing issues, and most crew scheduling problems generally don't qualify, since these are considered within the airline's normal operational control.

Frequently Asked Questions

Who decides if circumstances were genuinely extraordinary?
If you disagree with the airline's assessment, ADR schemes or ultimately the courts can review and decide the matter based on the specific facts.

Does the length of delay affect whether I'm covered?
Compensation eligibility depends on both the extraordinary circumstances test and the length of delay or notice given for cancellation — both elements need to be considered together.
