OP here... ...reporting!

So my Mom is here in the US and here's what happened when she checked-in at Mumbai. The agent saw the printout of the travel itinerary, looked up her reservation on the computer and asked her if she had any credit card authorization documents. As I had instructed my Mom, she asked him why would they be required if the ticket was purchased through a travel agent (travelocity.com). He said, "Okay", and that was the end of the conversation!!!
