Jet Airways has suspended its international flights, stoking fresh fears about the future of India’s largest private airline.

On Thursday the firm, which is grappling with a $1billion debt mountain, was forced to ground 10 of its aircraft over late payments to its leasing firms.

Some local media outlets claim that the airline is now operating only 14 of its 100 planes, taking it below the 20-aircraft minimum that carriers in India are required to maintain if they wish to run international services, the BBC reported

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.
