A lot will depend on what type of flying you're going to be doing. Flying domestic you can at least read a menu and ask questions or place a special order in your native (I presume) tongue. International will be harder, unless of course you take a job in India. When we get catered out of India, they label all the food Veg or Non-Veg.
