Yeah, that doesn't work in practice rather frequently. I was traveling 2 years ago with 4 people - flight was delayed enough that we were entitled to a 600EUR per person compensation (2400EUR in total, which is already something..). The captain of the delayed flight said that the delay was due to a previous delay in some other airport of the same aircraft due to some "traffic jam" (= not due to weather). However, when requesting the compensation, I was immediately shut down by the airline that this delay was due to "unforeseen circumstances" and what that exactly was, is a business secret that they can't disclose (wth?). They essentially told me to get lost and I'm free to file a complaint/dispute with the consumer protection agency. I reached out to the Italian consumer protection agency (idk what the exact name was) who according to EU rules is responsible for solving these disputes but they never answer to emails or to the online form that they have for these disputes. The EU wide organization that deals with these topics says that they can't do anything and only the Italian consumer protection agency as the authority to deal with this.. but they are ghosting me.
