Ryanair canceled our fllight at the London Stansted airport with no warning. According to European Union we are entitled to compensation for €250 per passenger . Ryan air denied our claim due to safety With no detailed explanation. We are not aware of any bad weather condition on that day . I would like to take this claim to the higher authority than Ryan air customer service but I Do not want to involve third-party. Was anybody in the same situation and do you know what to do next? I Would appreciate any help with this matter.
