The company said Julie Southern and Andreas Bierwirth will not seek re-election to the company's board at the next annual general meeting, while Nick Leeder will step down on Sept. 30.
They will be replaced by Harald Eisenächer, Detlef Trefzger and Ryanne van der Eijk.
Eisenächer has held executive positions with Germany's Lufthansa and travel firm Sabre Travel Network, while Trefzger and Eijk have experience in the transportation industry.
Eijk, who had worked with Netherlands-based KLM airlines for 20 years, will also become one of the board's employee representative directors.
