Thanks for your replies, especially Key8 and Yuropeflyer. As predicted, Edelweiss have denied the claim. This is their response (google translated from German - sorry!):

In the machine which was used for the rotation Zurich - Gran Canaria - Zurich, the pre-rotation caused a technical delay.
An unforeseen technical defect was identified in the aircraft planned for and from the flights from Zurich to Gran Canaria. The necessary repair took some time, which interrupted the flight rotation.

This unexpected event, which was neither predictable nor predictable, preventable or even influenceable for us, meant that various changes to the timetable had to be made to ensure that your flight was carried out.We understand that the delay has affected not only our timetable but, above all, our passengers' itineraries. Nevertheless, we point out that the law applicable in some EU Member States according to the ECJ ruling of 19 November 2009, according to which compensatory payments are due in the event of a departure delay of more than 3 hours, does not apply in Switzerland.

So, they are claiming technical difficulty? Does this mean that we don't have a case? Also, they are using the "this doesn't apply to Switzerland" thing as expected.

Thoughts on how to proceed would be very gratefully received!!! Thanks in advance!
