Etihad Aviation Group's chief financial officer Mark Powers has left the company and its head of treasury Adam Boukadida has been appointed in an interim capacity, the airline said. Mr Powers "decided to return to the United States for personal reasons", an Etihad Airways spokeswoman said in a statement to <em>The National</em> on Tuesday. Mr Boukadida will fill the role as Etihad searches for a permanent replacement for the position. Mr Boukadida has been interim chief financial officer since March, according to his LinkedIn profile. The executive role changes come amid a turnaround plan at the Abu Dhabi airline to return to profitability. Reuters first reported on Tuesday of the executive role changes.
