InterGlobe Aviation Ltd, owner of India's biggest airline by market share IndiGo, on Thursday appointed Ronojoy Dutta as chief executive officer (CEO) for five years, according to agency reports.

Dutta, who earlier served as a United Airlines executive and Air Sahara's president, joined IndiGo as principal consultant in December last year. At that time, IndiGo had announced that Dutta would be responsible for developing a five-year plan for the airline.

His appointment comes over a month after IndiGo's CEO-appointee Greg Taylor resigned from the company. At that time, sources had told Business Standard that Dutta's appointment as principal consultant at the airline was the pressing reason behind Taylor's resignation.
