Airlines who operate in these sectors shall give you additional advantage in selection procedure.

Helicopter Pilot is a very good option. They have options in VIP flights, tourism flights, private flying, government flying, etc. You will have to appear for the course called CHPL (Commercial Helicopter Pilot License). There are various institutes which conduct such courses. Since you have just cleared your class 12, I expect you to be thorough with your studies. You may appear for NDA or Coast Guards, where you can become an Assistant Commandant under Short Service Commission and after finishing your commission of 14yrs you can easily join commercial flying. This will save you money as all your training shall be done on government expenses. Otherwise, if you go for training on your own, you can expect a fee of around 25-35 Lacs. Think wisely and then proceed accordingly with your choice.
