I'm convinced ( but maybe I'm wrong)that AAB is very sensitive about the image of Q.A. Worldwide ( and about his image ..off course!).
I don't think he can remain insensitive for a long time against all the remarks and ( true)critics that have been raised by former or actual crew against him and the airline.(newspaper,articles,pprune.....)
We all known the truth.I do not believe one second that those courageous people who contacted The press just did it for " Fun", sure they have a serious issue to share.
But Unless he is willing to tarnish further more the image of Qatar Airways ,AAB has to change his attitude soon or later.( blaming the crew won't change anything).
If the article is true, I am sure a @#$%storm will brew with OneWorld partner American Airlines and it's Flight Attendants. I can't see QR remaining in the alliance if this is what goes on.
He can't hide from scrutiny like the old days.
