A lot of ad-hoc cancellations going on with unhappy/complaining customers. Right now AB is leasing aircrafts from other airlines to go on with their schedule. Personally I don't give them much time as they are not too big to fail (like AZ). As EY and LH now cooperating I think LH will take over major operation especially out of DUS with Eurowings. Berlin market is crowded with FR and EZY. So might be difficult for LH to get in this market (assuming FR + EZY will expand once AB will collapse).
