Passengers are stranded in India and around the world after Jet Airways suspended all international flights.
Flights from London, Paris and Amsterdam are among those grounded amid fears about the survival of India’s largest private airline.
The airline cancelled all international flights until Monday when, according to reports, it will meet its lenders again to try to secure funding.
Jet Airways is saddled with more than $1bn (£765m) of debt.
It is seeking a financial lifeline to avoid collapse and, on Thursday, grounded 10 planes over unpaid fees to leasing firms .
These were the latest flights to be grounded and it was not clear how many of its fleet of more than 100 planes was still in operation. Local reports suggested that it was barely a dozen.
The airline flies on 600 domestic and 380 international routes – but carriers in India must maintain a fleet of least 20 aircraft to continue to operate international services.

From London, the airline initially confirmed it had cancelled its flights between London, Paris and Amsterdam and India for 12 April, but later said that all international flights would be cancelled between 12 and 15 April.
It said it “regrets the inconvenience caused” to its passengers and was “working to minimise guest inconvenience”.
“In parallel, the airline’s management and its key stakeholders including its consortium of lenders, continue to work closely towards resolving the current situation,” it said.
There was no statement about the status of domestic flights.
