Air Vanuatu announced that it had cancelled international flights for four days and was considering bankruptcy protection for the South Pacific state-owned carrier.
It said international flights were cancelled until Sunday and flights after that day were “under review”.
In a statement, Air Vanuatu said: “The Vanuatu government is now considering placing Air Vanuatu into voluntary administration.
“The international firm Ernst & Young has been appointed to assist the Vanuatu government in reviewing available options and put forward recommendations.”
Thousands of travellers have been left stranded by the cancellations.
