Recently I was flying from BER (Berlin, Germany) via FRA (Frankfurt, Germany) to IAD (Washington, USA). The airplane, that was designated for flight BER-->FRA arrived late due to bad weather at its starting airport. Therefore, my flight from BER to FRA was delayed, I missed my connecting flight to IAD and arrived ways more than 3 hours at my destination. However, the weather at my departure airport BER was fine for departure as other planes started without any issues.
So my question is: am I entitled for compensation? Are there any legal documents or resources, that would back this up?
Update: According to newspaper sites, the decision in case Jager v easyJet 2013 suggest, that adverse weather is not grounds for rejection of a claim under EC Regulation 261/2004 unless the ‘flight in question’ was directly affected by the weather. Is there any legal document backing this claim up?
