Jet shares down 5% amid reports of ex-CEO's exit from advisory role

Shares of Jet Airways on Monday fell as much as nearly 5% amid reports that former two-time CEO Nikos Kardassis has quit from an advisory role in the airline. The Greek-American aviation veteran had rejoined the cash-strapped airline earlier this year to advise on cost-saving and productivity improvements. He had served as Jet Airways' CEO during 1994-1999 and later in 2009-2013.
