None of the Indian airlines are currently members of any airline alliances, so knowing that your airlines are in oneworld/star doesn't really help. I think AI (and thus IC?) is supposed to join Star in March... don't really know how award tickets will be.

If you have AA miles, they'll let you book a domestic 9W (Jet Airways) ticket for 20K miles according to their award chart, plus I think a $20 phone ticketing fee. I've never tried this and have no idea how availability is.

It seems UA will give you a 9W ticket for 35k miles, probably with a $25 ticketing fee?

I think NW gives you award tickets on 9W or IT (Kingfisher). CO lets you earn on IT but not redeem, AFAIK.

Seriously, though, paid tickets are like $130 return; is that really worth burning 20,000 miles on? You can get far better deals for your miles.
