As the Abu Dhabi-based carrier struggles with investments in European airlines, Australian James Hogan is to standdown as head of the Etihad Airways group, the company said on Wednesday.
After piloting the state-owned Gulf airline through more than a decade of growth, Hogan will leave his post in the second half of 2017, Etihad Aviation Group said in a statement.
Hogan was the architect of a strategy that saw Etihad buy significant stakes and make major investments in other airlines, notably Air Berlin and the long-struggling Alitalia.
But Etihad Aviation Group chairman Mohamed al-Mazrouei said it was time for a company-wide review, following continued cash injections into Etihad's partners.
"We must progress and adjust our airline equity partnerships even as we remain committed to the strategy, "Mazrouei said in the statement.
"We must ensure that the airline is the right size and the right shape."
Hogan's approach was in stark contrast to the strategies of fellow Gulf airlines Emirates, based in Dubai, and QatarAirways, which instead invested in developing their own services.
It saw Etihad spend hundreds of millions on stakes in foreign airlines, including acquisitions of 49 per cent ofAlitalia, 29 percent of Air Berlin, 19.9 percent of VirginAustralia and three per cent of Irish carrier Aer Lingus that it offloaded in 2015.
