Hi,

I like to suggest you that, better do B.tech in aeronautical or aerospace engineering in india , you can do pilot training either through commercial pilot training schools which will prepare you for obtaining Commercial pilot license . With this , you can all for job in airlines.

India, comparatively commercial pilot training institute are very costly and highly competitive.  If you are from a good financial background,  then go for it.

If not , then you can clear  Afcat exam, which is opportunity through which you can become a pliot in airforce .
