New Delhi: Two key executives, including chief commercial officer Samyukth Sridharan, at low-fare carrier SpiceJet Ltd have resigned at a time when the airline is expanding regional operations and set to post a loss this fiscal.

Sridharan resigned late last week after the airline's chief executive Neil Mills returned from his new year's break outside the country, according to two officials at the Gurgaon-based airline, who did not want to be named. Sridharan has a bachelor of technology degree in metallurgical engineering from the Indian Institute of Technology, Madras, and a postgraduate diploma from the Indian Institute of Management, Bangalore.

Sridharan, who joined the airline four-and-a-half-years ago, was one of the few top managers at the airline who had stayed back after Kalanithi Maran took control of the carrier in 2010. Sridharan declined to comment on the reason for his exit.
