Tony Tyler has announced he will step down from the role as chief executive and director general next year.
Tyler has been head of the International Air Transport Association since 2011 and will resign following the next Annual General Meeting of IATA in Dublin in June 2016.
"Tony Tyler is a very effective leader of IATA, who is achieving much in his role as Director General and CEO," said Andrés Conesa, chairman of the IATA Board of Governors, and Aeromexico CEO. "I regret that he will be leaving the association, but respect his decision to retire next year after a long and successful career in aviation."
Coseca said an executive search is now underway with the successor due to be formally announced in Dublin next year.
"After five years as director general and CEO of IATA, I believe it will be time for me to retire and leave the organisation," said Tyler, a former CEO of Cathay Pacific.
"It is a great privilege and responsibility to lead IATA, and I am proud of what the IATA team is achieving during my term of office."
