As I understand it from some insiders and former insiders, Saad did some good but was impossible to work with and his departure was only a matter of time.
The "new" CEO is difficult (nearly impossible) to work with and mercurial in temperament.
The Director of IT has walked - only a few weeks before a major transition to Amadeus, probably the biggest IT project in the airline's history - following a row with her.
There is now a complete case of "press-on-itus" - which the CRM instructors spend hours instructing Captains to avoid - from those now running the IT transition. It may work out OK, it may not.
The real question is who goes first - the Chairman or the CEO?
