The Indian airline, which is believed to be now operating 14 aircraft down from a peak of 119, has been undergoing financial issues for some time.
It is now reported in media in India and South East Asia to have pulled flights on its entire international progamme for two days.
The decision comes following confirmation earlier this month that Jet would reduce its Heathrow-Mumbai service from three times a day to twice daily.
At the same time it was believed the airline had shied away from introducing a second daily Heathrow-Delhi flight
The confirmation came after Jet Airways suspended its Manchester-Mumbai route until the end of April last month amid its worsening financial position.
Chairman and founder Naresh Goyal has since stepped aside to allow fresh investment in the carrier he set up in the early 1990s.
Goyal’s resignation as chairman in March opened the door for a consortium led by State Bank of India to take a majority shareholding.
Jet Airways’ new backers have pledged to pump INR 1,500 crore (£162 million) into the airline in the interim, allowing it to re-deploy a number of grounded aircraft.
