Debt-ridden Jet Airways has slipped into further trouble with its Singapore flights indefinitely suspended amid the ongoing cash crunch and a paucity of money to pay dues to aircraft lessors, Singapore\u2019s Changi Airport said in a tweet. Further, cash-strapped Jet Airways fleet is also down to 14 flying aircraft from as high as 119 earlier, CNBC TV18 reported. Financial Express Online has sent queries to Jet Airways about the same. Jet Airways\u2019 former chairman today said that he has pledged 26% stake in the airline as security with the Punjab National Bank against loans. This is about 2.95 crore shares. The pledge was submitted on 4 April as "security for existing\/ new borrowings taken by Jet Airways (India) Ltd,\u201d Jet Airways said in a BSE filing. #ADVISORY: @jetairways (9W) has suspended its services to and from Singapore until further notice. Passengers are advised to contact their booking agent or the airline directly (firstname.lastname@example.org) for available options. \u2014 Changi Airport (@ChangiAirport) April 11, 2019 Amid continuous flight groundings, Indian Oil Corporation (IOC) had previously cut Jet Airways\u2019 fuel supply due to non-payment of dues. The troubled airline was then operating 26 aircraft, about one-fifth of its original fleet which is now reduced to 14. Earlier, Naresh Goyal and his wife Anita Goyal had stepped down from the board of directors following the pressure of resolution. Goyal will lose out on his majority stake of 51% once the resolution plan for cash-strapped airline kicks in following which, his shares will be down to 25% and Etihad\u2019s shares will be down to 12%. Also, the State Bank of India (SBI)-led consortium of lenders is expected to take reins of Jet Airways after the resolution plan is effective. The lenders to the airline will infuse Rs 1,500 crore in Jet Airways for the majority control in the airline. Bankers have invited bids from investors to buy stakes in Jet Airways and infuse money into the airline. However, yesterday, the\u00a0deadline for initial bids submission was extended to 12 April 2019 as there was reportedly low interest on the part of investors to get stakes in the troubled airline. The earlier deadline was of 10 April.
