For somebody that travels the same route over and over again, what are some ways to save on airfare?
Yapta.com will track flight prices, so you can know when a good time historically is to make a bunch of reservations.  Also, Air India has a frequent flier program so I hope you have signed up for it... you could get free flights once you get enough points (although I would probably use your points for upgrades to business class).
