Rono J Dutta, former chief of the world's biggest carrier United Airlines, has taken over as president of Air Sahara in place of Uttam Kumar Bose.
Meanwhile, Bose is likely to handle other assignments within the Sahara India Parivar, probably in the housing sector, group sources said.
Dutta, who was the president of the United Airlines from 1999 to 2002, has been the advisor to the Air Sahara for some months after his superannuation from the US carrier.
He has been in the global aviation business for about three decades.
