After filing with the AESA several weeks ago I received an email yesterday referring my claim to the German equivalent because my flight originated in Germany (TXL-xMAD-BCN). The TXL-MAD was delayed for less than an hour for who knows what reason, causing me to miss my connection to BCN. My re-booked flight was roughly eight hours later.

Does anyone have experience dealing with the German body?

Can I ask AESA to reconsider, given my actual 'damage' was the 8+ hour delay at MAD, a Spanish airport?
