Austrian Airlines briefly elevated (former union rep) Capt. Mara to CEO status in the 80s to maintain political balance in an enlarged management team. (Reportedly no candidate with the right political "lean" and enough stance to counter the other CEO was found, which required the installation of two candidates of the opposite "colour" and to maintain equilibrium Capt. Mara was installed beside the "strong" candidate)
In more recent times, Capt. Walter Bock (also a former union rep who later became flight operations manager) became part of a four-man management team at Austrian Airlines from 2001 to 2004.
Neither of them is remembered for distinguished feats of management.
When Austrian Airlines took over Lauda Air and Niki Lauda left for new adventures Capt. Fitz (also a former union rep) became one of two CEOs at Lauda Air.
