HOW STRONG IS THIS CLAIM?

72/ 100

Good claim

Strong case — airlines usually pay these.

  • ✓The flight was cancelled. With less than 14 days notice and no timely re-routing, cancellations are strong claims.
  • ✓Weather was clear at both airports, removing the airline’s most common defence.
  • ⚠We could not fully verify the actual arrival time, so confidence is reduced.

✓ WHY IT MAY QUALIFY

Cancellation (Article 5). With under 14 days’ notice — and a same-day cancellation is by definition under 14 — compensation is owed unless the airline proves extraordinary circumstances.

Covered by EC261; the distance (5,848 km) sets the band: up to €600 per passenger.

☔ WEATHER AT THE TIME

Weather evidence is pulled from the airports’ own records when the claim is created — it’s what answers the airline’s “extraordinary circumstances” letter.

Why was KL645 cancelled?

  • Airlines don’t publish the cause, and we don’t know it for this flight.
  • Our radar recorded no other cancellations at Amsterdam that day.

To refuse compensation, the airline has to prove the cause was an extraordinary circumstance that could not have been avoided even if all reasonable measures had been taken (EC261 Article 5(3)).

Technical faults almost never count, and neither does a strike by the airline’s own staff. The EU’s top court has ruled on both (C-549/07, C-28/20).

Severe weather and air traffic control limits can count, but the airline must show they caused this flight’s disruption.

Weather can excuse compensation, never care: meals, hotel, and rebooking are owed regardless of cause.
