According to your other post I guess you are traveling in AP, why do you want to make things complicated by traveling via India? While boarding plane back to US, Indian official may give you hard time as they may have no idea about AP. I recently boarded flight from singapore to US in AP and it took me about 45 minutes to convince singaporean officials and united airlines staffs to let me board the plane in AP. But I may be wrong about India. Do your own due deligence.
