Your best bet is to review your travel interruption insurance to see whether it might cover this.
Incorrect
(again...). AB will not pay claims arising from circumstances prior to August 15th (refunds for tickets bought prior to that date, compensation for cancellations/delays before that date, etc). Anyone with that sort of claim has to join the queue and wait for the eventual distribution of assets (if any).
Anyone with a claim arising from AB trading/operating after August 15th on the other hand is a preferential creditor. They will be paid, in full, unless the Administrators/Trustees notify the Court of "insufficiency of assets", i.e. that in their opinion there are not even enough funds to pay the preferential creditors. It goes without saying that such an event would immediately ground the airline. And, obviously, no such statement has been made so far.
Such are the joys of German insolvency law.
(NB: If you're a lawyer and drafting a contract, those choice of law clauses are there for a reason.)
