For those who don't know, if your flight is delayed or cancelled in Europe, you can get up to 900$ because of EC 261, a regulation that was passed by the European Parliament in 2004.
Like when there is extreme weather or security incident, if they are denied boarding without reasonable grounds, their flight is delayed by more than three hours or their flight is cancelled with less than two weeks’ notice.
To get the money you need to keep any receipts for expenses incurred because of an affected flight.
I invite you to look the original, I summarized the story.
