India - Need advice on booking ticlets from Cochin to Chicago

I have 121K miles in delta/50K milesin continental...What is the best way to book a roundrip ticket for one of my relative who is going to travel this weekend or next weekend?

Even if i am not able to use the miles which site provides good deals for India-us flights?

delta has a blr-ord flight via cdg....my suggestion would be to try that route since blr would be the closest airport for your relative....

also, it is best to book on the airline website itself....going through an online ta can lead to problems in case you need to make any changes....
