Will ask him about Yash air and let you know. Have you done your Medical yet BTW? NOt trying to put you off but that is the first and BIGGEST hurdle you will need to overcome. Once you have passed your CPL initial issue it's quite easy.
Don't knock flying training in the US or OZ as the all told cost in India can work out to quite a bit in the end due to non-availability of instructors/aircraft etc. The nearest school to Bombay is Carver Aviation in Baramati and their costs seems quite reasonable but unsure about their ability to provide training on a sustained basis.
From your standpoint, do you see a potential for flying schools targeted towards recreational flyers?
