AirAsia Bhd (AIRA.KL) boss Tony Fernandes has told staff and analysts he will spend more time working on the budget airline and put his other business and sporting interests to one side, after a report questioning the company’s accounts sent its share price tumbling. The chief executive has said his other work will take a back seat as he focuses on repairing the financial damage done to Asia’s largest low cost airline, according to analysts and two AirAsia executives who spoke to Reuters on condition on anonymity.
