IndiGo CEO Ronojoy Dutta Thursday told employees that the airline's growth strategy remains unchanged and is firmly in place, amid reports of rift between two promoters of the country's largest carrier.
"I want to assure you that the growth strategy of the airline remains unchanged and firmly in place, and the management is fully charged by the board to implement it," Dutta said in a communication to employees.
Without directly mentioning about the rift between promoters, Dutta referred to media reports in this regard in the communication.
"I am sure that you are all aware of the press reports regarding alleged disagreements between our two promoters Rahul Bhatia and Rakesh Gangwal," he said.
