Comair CEO Erik Venter has resigned from the company to pursue his own interests.
Venter, who has been with South Africa-based Comair for 23 years, 13 of them as CEO, leaves at the end of July.
The board has not yet decided on a new appointment.
Venter leaves Comair in a much stronger position than when he started, having conceived and led a diversification strategy.
Other group businesses now contribute nearly 30% of profit before tax.
These businesses include the group’s investment in an aviation training academy with a global customer base, as well as its SLOW lounge business, its Food Directions catering unit, its travel business, and its investment in technology solutions for tourism, travel and aviation.
