Recently had a misconnect on my GVA-MUC-PEK resulting in a 24h delay. First leg was operated by EN (sold as LH codeshare) and delayed by 2:05. Filled claim form on LH website and received a message saying they were forwarding my claim to the operating carrier (EN).

Question is: can EN throw out my claim because their flight was "only" 125 mins late, or are they considered responsible for the delay in reaching my final destination?
