I've long believed that Vuyani was SAA's best and final chance at restructuring the airline successfully. I've been dealing with SAA and the rotating door of CEOs for 15+ years now dating back to the mid-2000s. In that time, most of the CEOs were either incompetent, thieves, politically unacceptable, or just there to mark time in a caretaker role (or some combination of the above).
Vuyani was different. He actually listened when others gave him advice. It made a world of difference. The unions backed him. The managers backed him. For the first time, SAA would come to partnership negotiations not with the "this is what we are going to do" attitude, but rather with a "what can we do together to be successful" approach. As I said in an interview with SABC in 2019 when I signed a codeshare agreement with SAA on behalf of my then airline, "for the first time in my memory, the different factions in SAA are actually working together towards a common goal rather than infighting". As someone who was privy to some of his plans for SAA, they were realistic and achievable.
Alas, the infighting was apparently happening at a higher level. Vuyani resigned the very day that Pravin Gordhan was reappointed as the Minister in charge of the Department of Public Enterprises. Read into that what you will. His exit sucked the life and morale out of an SAA team that was just beginning to believe again.
I have stayed in contact with Vuyani since his exit from SAA, and he is a true gentleman in addition to being a very sharp business exec. He will be successful elsewhere, unlike the SAA he had to leave behind.
