As the titel says, my flight with Vueling (VY6004) got cancelled due to 'adverse weather conditions'. It rained quite a bit in Florence, but the entire day this was the only flight leaving Florence to be cancelled. In Barcelona (BCN) 1 flight a couple hours earlier and 1 flight an hour and a half later was cancelled.

Could 'adverse weather conditions' be an actual claim, or is this some way to get out of having to pay for compensation?
