Meanwhile, former THAI president Piyasvasti Amranand has denied accusations the airline's losses in 2015 were partly caused by fuel-hedging decisions he line had made during his October 2009-June the on 2012 term.
The airline reported a net profit of 6.23 billion baht in 2012, net losses of 12.05 billion baht in 2013 and 15.61 billion baht and in 2014.
During a speech to lawmakers and policy-makers last month, Gen Prayut vowedto tackle inefficiency at loss-making and debt-ridden state enterprises, telling their executives to consider cutting their salaries as a means of reducing losses, particularly at Thai Airways.
"I will overhaul them. Each organisation hires a large number of people, but when they introduced early retirement incentive programmes to cut costs, only low-level staff left, not high-level executives," Gen Prayut said.
THAI said last week that staff cuts, outlined in its"Mutual Separation Plan' saved n the company 3,722 billion baht in the first nine months of this year.
