Hi,
I need to visit India frequently but am bitten by the high airfares. As of now, I spend an avg of 1200 - 1300 CAD for one return flight Toronto - Del - cal
What are some ideas to save on airfare? I take Air India since I prefer the direct flight(short duration).
I signed up for frequent flier programme but what is the translation factor of conversion of air miles to actual free flights? (like: fly 10 times and get 1 time free?)
Also, what is the cheapest season to go and come back?

Any other suggestions I also appreciate very much
