Oman Air has announced that the board of directors has accepted the resignation of the chief executive, Paul Gregorowitsch.
In a statement, the company said: “The board thanks Paul Gregorowitsch for his efforts during his tenure with the company.”
Abdulaziz Saud AlRaisi, executive vice president for products and brand development, will serve as acting chief executive with immediate effect until the permanent replacement of the chief is announced in due course.
The company gave no reason for the resignation.
Gregorowitsch, a former chief commercial officer at airberlin, took up his role in summer 2014.
Under his leadership the airline has undergone a period of rapid expansion.
However, the flag-carrier has been persistently loss-making and has been facing a rapid reduction in the amount of financial support it receives from the Omani government.
Losses for full-year 2016 were more than $330 million.
Before his departure, Gregorowitsch said earlier this year that the carrier would again make a loss in 2017.
