Well I have found the service on AF to be quite good, I don't really understand why some feel obliged to slag off their own flag carrier, especially as in the case of AF such a treatment isn't deserved.
AF isn't on the road to bankruptcy, let's not be silly. It does need to keep up with the market and deliver more sustainable profits in the long run.
You shouldn't believe what your are told about AF pilots, as their conditions are just about average compared to other European flag carriers, and especially compared to their KLM colleagues, who are believe or nor more costly for the company.
AF personnel and pilots have made significant efforts including the loss of leave days, pay freeze, retirement age now 65 iso 60. They have have no such "unsustainable" privileges as you say.
However, AF crew will not make more efforts as long as the government doesn't create a more favorable environment for the airline, in terms of airport charges, numerous taxes etc, as they feel every effort that they make is quickly absorbed by another new tax (like the one that will pay for CDG express)
