The company is 91 years old so they are already in the most dangerous phase for a mature company. It is very difficult for a company to live beyond 100 years. I do not enjoy saying that but it is what I have observed in the world. From all that I have heard they are in a very similar position to their friends in BA.
For the record, I do not work in the industry and have never flown QF for the simple reason that I have never had the opportunity.
