May well be, IŽd be surprised though if LH was going into this unprepared and without having obtained a quiet nod or two from those that may be in charge already.
After all, LH has been in negotiations with AB for a while already, trying to find an agreement on buying one or another part of the latter. As a part of this, already for a few months, nearly 40 AB aircraft are flying wetlease on LH and OS routes. That EY would pull the plug today was likely not foreseen though: when Ms. Merkel visited the UAE some months ago, she was apparently promised that EY would stand by their commitment at least until November (i. e., after the German elections!).
It may be that a court will see a breach of anti-trust rules here after todays developments, but the opposite can be plausibly argued as well.
Assuming the federal bank guarantee has been granted already earlier this year (it has been requested, but the response did not make it into the news as far as I know) and just been paid out today may well turn todays declaration of bankruptcy a legal formality and explain the mode selected: there has not been a caretaker appointed by the court as would have been the case, was there no money at all left. The company has been allowed to appoint their own manager for the process, which is a sign that the court did not see all lost. And if the company is allowed to attempt to rescue itself, what is to keep it from carving itself up and selling parts of itself to get money and to keep going?
