I booked an award ticket for my cousin, using my BA miles & credit card, flying on AA.

I will not travel with my cousin. But I found that I was required to bring the credit card to the airport according to the confirmation email:
"Please remember you must bring the card used to pay for this booking to the airport with you, for verification, before you can travel.
Your itinerary is detailed below."


I called BA, talked to three agents, and got three different answers.
- The first agent said there was no way to avoid this. I need to bring my card with my cousin when he checked in at the airport.

Since the first agent was very unfriendly, I called again and talked to another agent.
- The second agent said everything was set: I don't need to bring the credit card. The agent said since the ticket was booked using my credit card instead of my cousin's, my cousin will NOT be required to show the credit card used for booking.

Since the two gave me opposite answer, I called again and talked to a third agent.
- The third agent said my cousin would NOT able to check in, even if I would go to the airport with my cousin, because American Airline would ask my cousin to show the creidt card used for booking & would assume the ticket was fraud because the card was NOT under my cousin's name.


Since the third agent said the "show credit card" would be requested by AA agent at the airport while checking in, I called American Airlines.

I talked to three AA agent, two from reservation department, one from AAdvantage department. All of three saying AA would NOT require the credit card to be showed at the airport.

Sure I be assured that the "show credit card at the airport" will NOT be enforced, since AA is the carrier?

I am a little disappointed with BA now, for the very inconsistent answers from agents, always longer waiting time than AA while calling, and less friendly (this one maybe subjective) than AA.

Thanks for any comments.
