Vistara airline on Thursday announced it has introduced its first male cabin crew as part of plans to be an "equal opportunity employer". The crew took to the skies following the completion of a rigorous three-month safety and service training programme to the exacting standards of Tata and Singapore Airlines, the airline said in a statement. "Our total crew strength at present is around 500, and as we continue to scale up, we expect to have about 25-30 per cent male crew of the total strength over a period of time," said an airline spokesperson.
