Refusal to comply with EU Regulation 261/2004

Very disappointing experience with Swiss International Air Lines. Flight LX1111 arrived about 24 hours late at my final destination, causing me to miss my long-haul connection and lose a full professional working day. Under EU Regulation 261/2004, €600 compensation is clearly due for this length of delay on a long-distance EU-originating journey. Instead of providing proper evidence, Swiss keeps hiding behind a vague “airport restriction” without any documentation. They offered only CHF 47.70, which is completely inadequate given the disruption. The delay was bad enough — but the refusal to respect clear passenger rights and the lack of transparency is worse. I am now escalating the matter to the relevant authorities. Would not recommend.
