I can confirm that most left because of working conditions at QR. All left of their own accord. Most found it impossible to work for AAB. Some found the Acting GM Commercial a problem. At least one was partly influenced by his growing dislike of living in Doha (boring was the word he used).
Another one quit this week. Manager Qatar Airways Holidays. Same problem ... AAB and Fakhri (Acting GM Comm).
All were good guys who were frustrated by having Manager titles, but no authority.
The guy running FFP did quit (a Belgian I believe). The guy from London has taken over from him.
QR have a problem. The departure of so many senior managers in a short time must be difficult for any company to handle. And someone should be taking a good look at the reasons.
