If these are contractual items and they have arbitrarily taken them away then it’s not just deterioration, it’s a violation.
Did they say why? You would think a salary review or bonus would be coming up with the sacrifices the foreign pilots have made.
Is this a permanent change? If they are trying to recruit foreigners for the 380 this definitely won’t help their cause.
I wouldn’t bet the agencies are going to step in and do anything about it.
