I wonder how it is possible for AB to "leave an entire plane's luggage behind" at TXL, including the bags of the passengers who check-in and board in Berlin. If at TXL bags are checked right at the gate from which a plane departs a few meters away, how can a bag be misplaced? Soon I am travelling from TXL to MUC (taking the earliest TXL-MUC flight in the morning, which normally seems to board at gate A2), where I connect to AA onward to PHL (the same reservation). Given that I originate at TXL, I hope it will be OK with my bag.
