Questions

Is a delay at Grenchen caused by weather always an extraordinary circumstance?

No. The airline must show that the weather actually affected your flight and that it took all reasonable measures. Eurocontrol logs weather delay at Grenchen on specific days; if your day is not one of them, the weather defence has nothing behind it. If it is, the airline still has to connect it to your flight.

How do I find out if my Grenchen flight was delayed 3 hours?

Enter the flight number and date in the checker above. It pulls the recorded arrival time, works out the delay against the schedule, and shows what Eurocontrol and the airport weather logged for Grenchen that day.

Which airlines' passengers can claim after a Grenchen delay?

Any airline departing Grenchen is covered by EU261 regardless of nationality. Arrivals are covered when the airline is a UK or EU carrier.
