In top-level exodus at grounded Jet Airways, four senior executives, including chief executive Vinay Dube and his deputy Amit Agarwal, have quit the ailing airline.

Amid lenders scrambling to find a suitor, the cash-starved carrier on Tuesday announced the exit of three executives -- Dube, Agarwal and Company Secretary Kuldeep Sharma -- while a source said the carrier's Chief People Officer Rahul Taneja has also put in his papers.
