The sources said keeping in view the recent developments, SpiceJet's promoters have asked the airline's chief executive Niel Mills to stay on till the negotiations with the potential investor are concluded. Mills had resigned last week, but his resignation is yet to be accepted by the management. He is the third CEO of the Chennai-based private carrier in the past five years. Mills' exit from SpiceJet comes a few months after its Chief Commercial Officer Harish Moideen Kutty resigned. He had been hired by Maran for SpiceJet in 2010 from Gulf-based low cost carrier FlyDubai, months after the media baron had bought the airline from NRI promoter Bhulo Kansagra the same year. In the last fiscal, SpiceJet posted a loss of Rs. 191 crore. It has a market share of about 20 % compared with its main competitor IndiGo's 30 %.
