Few indian airlines honor the International Baggage allowance if you are flying the domestic segments within 24 hrs ( Even if not in the same PNR). But you need to send a E Mail or Call ahead to confirm this.

I was flying on a SFO-JFK-BRU-MAA iten on American + Jet Airways in 2009 and Jet had 2+1 baggage allowance then. From MAA to TRZ, Paramount and Kingfisher were ready to accept the same baggages, if I could show the International Ticket and Boarding pass. I got a E mail confirmation as well.

When I checked in at Chennai, I just mentioned that I'm flying in from USA and showed the SFO-MAA boarding pass, and Paramount agent checked in the extra bags without a question. The E mail printout was not even necessary. So just look up in the website or E mail the customer care. (Jet / Jet Lite / Jet Connect / IA / Spice / Indigo / KF) are serving DEL-AMD Sector.
