I'm not familiar with the changes in DEL since the new terminal opened. I am considering traveling ORD-CCU-ORD, using AA for ORD-DEL-ORD.

(a) If I am staying overnight in DEL on the outbound, will 9W take my luggage after I walk it through Customs? (Probably not but I thought I would ask.) (I know there's a same-evening connection but I would like to visit some friends.)

(b) On the return, Orbitz is showing lower fares if I take AI from CCU to DEL. I know AA has a relationship with 9W, but I don't know what arrangements it has with AI...will my luggage be interlined at DEL, or will I have to retrieve it and take it to AA?

Many thanks,
