The secretary general of the European Technology & Travel Services Association is to stand down.
Christoph Klenner, who has led the organisation for more than nine years, will be leaving in the third quarter of 2018.
He will continue to head the travel technology trade body while a successor is sought.
Brussels-based Klenner said: “It has been a true privilege to help establish ETTSA and build it into a strong organisation for the travel technology sector in Europe.”
He added: “I thank the ETTSA board of directors for their confidence in me, and for creating the inspirational and professional environment in which I have had the opportunity to work.
“But after more than nine years, the time has come for me to explore new professional endeavours.”
“I look forward to continuing to work closely with the board in the coming months, and giving my successor all the tools he or she needs to excel in this exciting role.”
Association chairman Simon Gros said: “The board regrets to see Christoph go. He has been a staunch defender of the independent travel distribution industry in Brussels and he leaves ETTSA in great shape.
“We will begin the search for Christoph’s replacement immediately and look forward to continuing the momentum he has built up.”
