The quickest way is to get all your ratings in the USA. It will take 6-8 months and cost betwen $50,000-80,000 depending on where you go. Then you have to convert your licenses to Indian ones (a nightmare I'm told). If you are young enough you can apply via the cadet program where the airline picks up the tab for all your training, but you have to sign a training bond of several thousand dollars. Look up the websites of all the key players and click on careers link. Good luck! The time to do it is now. Oh I almost forgot, don't get into the airlines just because of the money--you will regret it. Find out if you have the aptitude for it and a passion for aviation. Too many folks seem to be doing it in India and elsewhere for the wrong reasons.
