Aegean names Michalis Kouveliotis chief executive as Dimitris Gerogiannis steps down

Athens, Greece. Greek airline Aegean announced on October 12 that Michalis Kouveliotis would become chief executive officer with immediate effect. He replaces Dimitris Gerogiannis, who is leaving the position after 20 years but will stay with the airline in an advisory capacity.

Leadership transition

According to the company, the appointment forms part of a handover to a new generation of executives. Gerogiannis, who was among Aegean’s founding executives, will retain oversight of the group’s training centre and technical base, helping develop both facilities in line with its future direction.

Aegean said Kouveliotis had held the chief financial officer position since before its listing on the Athens Stock Exchange. In early 2025, he became deputy chief executive, assuming responsibility for coordination across the airline’s business divisions as preparations for the handover advanced.

Chairman recognises both executives

Aegean chairman Eftichios Vassilakis credited Gerogiannis and the late Theodoros Vassilakis with establishing the airline’s culture of quality and customer service, alongside its commitment to fairness and collaboration.

The chairman said Gerogiannis brought an unusual combination of technical knowledge and a people-centred approach. Describing him as a co-founder, Vassilakis said the leadership change would not alter the significance of his contribution.

Vassilakis added that Gerogiannis would keep supporting Aegean during the transition from its founding leadership to the next generation of executives.

Regarding Kouveliotis, the chairman said the incoming chief executive had proved his capacity to support the airline during times of expansion as well as crisis.
