Well my problem is that I'm in Canada and, if I understand properly, I would have to take them to small claim court in Spain?

OK, here's what I could find: From this, it seems that other airlines had no troubles flying at that time. Is there any way to prove that the cancelation was not related to the strike? What should be my next course of action? Thanks.

Well, I actually speak French but I didn't find any info on Google originally. Here's a link that I found: French ATC Strike 26th and 27th May I don't know if we can say it's a credible source How would I be able to check if other flights were departing at the same time? I could not find a archvied schedule on the airport's website.

Hi, On may 26th, I was supposed to take an EasyJet flight from Barcelona to Paris but it was canceled at the last minute. We were offered a re-route on the next day, but it caused us to miss our connecting flight and we had to buy a new ticket (for a total of more than 600£). At that time, I was told that the flight was canceled for "crew issues", i.e. they didn't have enough crew members to operate the flight. When we got back, I've contacted EasyJet to get a refund because this reason does not qualifies as "extraordinary circumstances" as defined the European legislation and I wanted to receive the monetary compensation defined by the law. The reason that they now state is that "The flight was cancelled due to a crew issue, they had used all of their flight hours as a result of the ATC strikes and so were unable to operate the cancelled flight. This is extraordinary circumstances. ATC restrictions prevent aircraft operating to within 5 hours of the original schedule." and that "The strikes were initiated by French Air Traffic Control over pension reform proposals." However, I was not aware of those strikes at that time and I'm not sure of how I can verify that. I searched the news archive and I didn't find anything. Is it possible to verify this with an independent source? Is there anything else I could do to receive a monetary compensation? Thanks. As a side note, does anybody know if it's possible to make a complaint to the Spanish authority by email? All I found was the postal adress in Madrid: Reclamaciones - Derechos de los pasajeros - Ministerio de Fomento
