How do you find really cheap airline tickets to india?

Im just a kid so I have nooo idea how to find airline tickets online or anything. A family friend of ours is getting married in India and my dad said that if I can find cheap round trip airline tickets, we can go. But I dont even know where to start. Air India is what we flew last time we went to india. This trip would be at the beginning-middle of march 2009.

You will find the cheapest flight to an Indian airport from any part of the world, in the website referred below. If your departure airport is USA click on Yatra.com banners. Don't believe them, check the fares offered by "Makemytrip". You can also see fares offered by British Airways, Virgin Atlantic, Air France-Canada and many others.
