When flying home, I'll be flying PNQ to DEL, 3 hour layover, DEL to ORD, and then on to DFW.

My question is: when I check in to Sahara Airlines in PNQ, will I be able to check my bags all the way through to DFW, or will I have to pick them up in DEL and then re-check to DFW? I ask as when flying out here, I checked my bags all the way through to PNQ, but I still had to pick them up at DEL International and carry them to DEL Domestic and then recheck.
