One issue you will have to deal with is that India requires a great deal of notice for overflight permits. Yes I realize you will be landing there, but you will still require over flight permits. Your best course of action is to get an international handler like Universal Weather to do that for you. It will cost some money, however, they take care of the everything and usually will have a rep meet you when you land. They file all the flight plans and make all the calls. Well worth the money in the long run. It is cheap insurance to ensure the flight goes smoothly.
