Last November, the airline took delivery of its first Airbus A350XWB which cost more than $US100 million.
In January, flights began to Sydney and Los Angeles but by the end of March, the airline was forced to suspend air travel due to the Covid-19 outbreak.
This week, the airline's chief executive, Andre Viljoen, said the situation was like "sitting with a noose" with no way to wriggle out.
Mr Viljoen said defaulting on loan or lease repayments for one aircraft could make Fiji Airways "lose everything and go belly up".
